Provides a bridge specifically between Claude Code and the OpenClaw management plane via JSON-RPC
The OpenClaw control plane MCP server. Operate the gateway's full management surface from Claude Code, Cursor, or any MCP client β list and trigger crons, inspect sessions, configure agents and channels, manage skills and secrets, drive the doctor memory plane, pair devices, approve exec/plugin calls. 143 typed tools covering every JSON-RPC method the gateway publishes.
demo
Different from the upstream openclaw-mcp, which only wraps /v1/chat/completions. This one talks the JSON-RPC protocol used by the OpenClaw Control panel β so you can operate the gateway itself (its crons, sessions, agents, channels, skills, secrets, β¦), not just chat through it.
Without vs with
Without openclaw-control-mcp β you bounce between the Control panel UI, your terminal, and Claude Code. "List my crons" means opening the SPA. "Tail this agent session" means staying in the panel and refreshing. "Why did this skill fail?" means hunting through logs.tail manually. The assistant can chat through the gateway but it cannot operate it.
With openclaw-control-mcp β the same assistant queries openclaw_cron_list, follows up with openclaw_sessions_tail to watch a turn in flight, asks openclaw_skills_status for diagnostic data, rotates a secret via openclaw_secrets_set, and approves a stuck openclaw_exec_approval β without you ever leaving the chat. The Control panel becomes an audit interface, not a daily-driver.
Quickstart
bash
# Claude Code β registers a stdio server under the default config
claude mcp add openclaw-control -- npx -y openclaw-control-mcp
One-click install from supported clients:
On first start the wrapper generates an Ed25519 device identity and surfaces a pairing request id. Approve it once in the OpenClaw Control panel, the gateway issues a device token, and every subsequent call uses it transparently. Full pairing flow below.
Status
0.8.1 β published on npm, indexed on the official MCP Registry as io.github.smurfy92/openclaw-control-mcp. Multi-instance gateway configs, file-based secrets (.env + store.json mode 0600, no OS keychain access β see ADR-006), 143 typed tools across the 128 published JSON-RPC methods, plus two escape hatches: openclaw_introspect enumerates every method/event the gateway publishes in its hello-ok, and openclaw_call lets you reach any method that doesn't have a typed wrapper yet β so new gateway endpoints are reachable without waiting on a release.
The Ed25519 signed handshake is verified live against gateway 2026.4.12+. On first start, the wrapper generates a long-lived device identity, persists it under ${XDG_CONFIG_HOME:-~/.config}/openclaw-control-mcp/store.json (mode 0600), signs the connect frame, and surfaces the resulting pairing request id so you can approve it once via the Control panel. After approval the gateway issues a device token (in hello-ok.auth.deviceToken) which is cached per-gateway and used on subsequent connects to grant scopes.
The wire format (frame types, field names, signing canonicalisation, scopes) was reverse-engineered from the minified Control panel bundle (/api-docs/assets/index-*.js) and cross-checked against openclaw/openclaw/scripts/dev/gateway-smoke.ts. It is not officially documented. Behaviour may change without notice if OpenClaw updates the gateway.
First-run / pairing flow
Start the wrapper (Claude Code does this automatically once registered in ~/.claude.json).
Ask Claude to run openclaw_device_status. The first call:
generates an Ed25519 keypair and persists it to disk,
opens a WS to the gateway,
sends a signed connect frame,
the gateway replies with PAIRING_REQUIRED and a requestId,
the tool returns { pendingPairing: { requestId }, nextStep: "approve in Control panelβ¦" }.
Open the OpenClaw Control panel β Devices tab β approve the request whose id matches.
Ask Claude to run openclaw_device_status again. This time the gateway accepts the connect, returns auth.deviceToken in hello-ok, the wrapper caches it, and paired: true plus the granted scopes appear in the response.
From then on, scoped tools (openclaw_cron_list, _status, β¦) work normally.
Install
From npm (recommended)
bash
claude mcp add openclaw-control -- npx -y openclaw-control-mcp
git clone https://github.com/smurfy92/openclaw-control-mcp.git
cd openclaw-control-mcp
npm install
npm run build
claude mcp add openclaw-control -- node "$(pwd)/dist/index.js"
Configuration
The wrapper requires the WebSocket URL of your OpenClaw gateway. The public Hostinger HTTPS hostname does not expose the WS endpoint β you need the URL the Control panel itself uses internally.
Copy the gatewayUrl field (typically ws://127.0.0.1:18789, a Tailscale ws://100.x.y.z:18789, or a dedicated wss://β¦ host).
Use with Claude Code
Recommended: register, then configure in chat
The slickest path β no ~/.claude.json editing, no env vars. After installing (npx or from source), in chat:
"Configure OpenClaw with gateway wss://your-gateway.example.com and token <your-token>"
Claude calls openclaw_setup({ gatewayUrl, gatewayToken }), the values get persisted to ~/.config/openclaw-control-mcp/store.json (mode 0600). The next call to openclaw_device_status triggers the WS handshake and pairing flow.
openclaw_setup_show reports the effective configuration, openclaw_setup_clear wipes the persisted config (without touching the device identity / token).
Alternative: env-var-driven
If you prefer env vars (they take precedence over the stored config), edit ~/.claude.json:
Restart Claude Code β openclaw_cron_list and friends will be available.
Secrets & the .env file
The server never touches your OS keychain β no security / secret-tool call, no permission prompt, nothing to approve. Since 0.8.0 secrets resolve from exactly two places, in this order:
#
Source
Notes
1
Real environment variables
Always win. OPENCLAW_GATEWAY_TOKEN=β¦ npx -y openclaw-control-mcp is a valid one-shot override.
2
A .env file
Loaded into the environment at startup. Never overwrites a variable that is already set.
3
store.json (mode 0600)
What openclaw_setup and the pairing flow write. Plain JSON, in your config dir.
.env candidates, highest precedence first:
$OPENCLAW_ENV_FILE β explicit path
./.env β the directory the server is started from
Copy .env.example, fill it in, then chmod 600 .env. The server warns on stderr if the file is readable by other users. The parser is deliberately minimal β KEY=value, export KEY=value, "quoted", '''raw''', # comments β with no variable interpolation, so a secret is never expanded or reinterpreted.
Want the server to never write a secret to disk? Put OPENCLAW_DEVICE_PRIVATE_KEY + OPENCLAW_DEVICE_TOKEN in the .env (get them from an already-paired install with npx tsx scripts/export-ci-secrets.ts). Env-supplied identity short-circuits the store entirely.
--health reports which .env files were loaded and which variables they supplied.
Upgrading from 0.5.0 β 0.7.0 (keychain removal)
Those versions kept secrets in the OS keychain and left blank fields in store.json. Run the one-shot import once, before your next session:
It reads the keychain, writes the values into store.json (mode 0600), and prints the security delete-generic-password β¦ / secret-tool clear β¦ commands for the now-unused items β it never deletes anything from your keychain itself. Running it twice is a no-op. This is the only code path in the package that reads a keychain at all; it is dynamically imported behind that flag and never runs on normal startup.
If you'd rather not migrate, openclaw_device_repair wipes the orphaned device and the next connect re-pairs from scratch.
Environment variables
Variable
Required
Description
OPENCLAW_GATEWAY_URL
yes
WebSocket URL of the gateway (ws:// or wss://)
OPENCLAW_GATEWAY_TOKEN
recommended
Gateway login token
OPENCLAW_GATEWAY_PASSWORD
optional
Extra password (some gateway configs require it)
OPENCLAW_TIMEOUT_MS
optional
Connect / request timeout (default 30000)
OPENCLAW_DEBUG
optional
Set to 1 to log every WS frame to stderr
OPENCLAW_CONTROL_HOME
optional
Override the directory used to persist store.json (defaults to ${XDG_CONFIG_HOME:-~/.config}/openclaw-control-mcp/). The legacy OPENCLAW_CLAW_HOME is still read as a fallback.
OPENCLAW_ENV_FILE
optional
Explicit path to a .env file. Loaded before anything else reads the environment; takes precedence over ./.env and <configDir>/.env. See Secrets & the .env file.
OPENCLAW_HTTP
optional
Set to 1 to expose the MCP over Streamable HTTP at /mcp instead of stdio. Equivalent to passing --http.
OPENCLAW_HTTP_PORT
optional
HTTP port (default 3333). Equivalent to --http-port=N.
OPENCLAW_HTTP_HOST
optional
HTTP host (default 127.0.0.1). Equivalent to --http-host=H.
OPENCLAW_MOCK
optional
Set to 1 (or pass --mock) to swap the WebSocket gateway for an in-memory MockGateway. Lets you exercise the MCP without provisioning a real gateway β for CI, demos, or dry-runs. State is kept in-process and discarded on exit.
Multi-instance: per-call instance parameter
Every tool accepts an optional instance field so a single MCP can target several gateways without flipping the active default first:
jsonc
// route this one call to the 'work' gateway, regardless of the active default{"name":"openclaw_cron_list","arguments":{"instance":"work","limit":10}}
Configure each gateway with openclaw_setup({ instance: "work", gatewayUrl, gatewayToken }), list them with openclaw_setup_list, switch the active default with openclaw_setup_select_default. When OPENCLAW_GATEWAY_URL is set in the env, it overrides everything (including a instance arg) β the env-var path always wins.
HTTP mode
For clients that don't speak stdio (Cursor, Continue, Cline, Zed, browser), run the MCP as a Streamable HTTP server:
bash
# Loopback (default 127.0.0.1:3333), no bearer β fine for local trust
npx -y openclaw-control-mcp --http --http-port=3333
# Same, but with bearer auth on (recommended even on loopback)
OPENCLAW_HTTP=1 OPENCLAW_HTTP_BEARER="$(openssl rand -hex 32)" \
npx -y openclaw-control-mcp
# Bound to a public interface β bearer is REQUIRED (server refuses to start without)
OPENCLAW_HTTP=1 OPENCLAW_HTTP_HOST=0.0.0.0 OPENCLAW_HTTP_PORT=3333 \
OPENCLAW_HTTP_BEARER="$(openssl rand -hex 32)" \
npx -y openclaw-control-mcp
Endpoint: POST/GET http://<host>:<port>/mcp (MCP Streamable HTTP, stateful β each client gets its own session id). Stdio remains the default; the HTTP server only starts when explicitly enabled.
Auth behaviour:
OPENCLAW_HTTP_BEARER set β every /mcp request must include Authorization: Bearer <token>. Mismatched / missing tokens get 401 Unauthorized with a WWW-Authenticate: Bearer realm="openclaw-control-mcp" header. Comparison is constant-time.
OPENCLAW_HTTP_BEARER unset + bound to loopback β starts with a stderr warning. Anyone with local shell access can invoke every tool.
OPENCLAW_HTTP_BEARER unset + bound to a non-loopback host (0.0.0.0, public IP, etc.) β the server refuses to start. Public binding without auth is a takeover risk and not negotiable.
For long-lived deployments behind a reverse proxy, terminate TLS at the proxy (nginx, Caddy, Traefik) and forward to 127.0.0.1:3333/mcp β the bearer protects the proxy β MCP hop too.
Mock mode (no gateway required)
Set OPENCLAW_MOCK=1 (or pass --mock) to swap the WebSocket client for an in-memory mock. Useful for:
CI β run tests / demos without a live gateway.
Workflow rehearsals β dry-run a sequence of cron.add / cron.update / config.patch calls before pointing at prod.
Onboarding β try the MCP without provisioning a gateway instance.
State (cron jobs added, config patches, sessions) is kept in-process and discarded on exit. The mock seeds one cron job (sample-weekly) and one session so list calls return non-empty. Methods without a canned handler return { mock: true, ok: true } so nothing crashes β extend src/gateway/mock.ts to specialise additional methods.
Cron templates (no schedule syntax to remember)
Four wrappers on top of cron.add synthesize the wire format for the most common cases:
jsonc
// every Friday at 09:00 Paris, send a weekly digest to a Telegram channel{"name":"openclaw_cron_add_weekly","arguments":{"name":"weekly-digest","dayOfWeek":"fri","hour":9,"minute":0,"tz":"Europe/Paris","message":"Compose the weekly digest β¦","channel":"telegram","to":"-1001234567890"}}// every day at 07:00 UTC{"name":"openclaw_cron_add_daily","arguments":{"name":"morning-check","hour":7,"tz":"UTC","message":"Run the morning checks."}}// every 15 minutes (clock-agnostic){"name":"openclaw_cron_add_every","arguments":{"name":"ping","intervalMinutes":15,"message":"ping the upstream"}}// one-shot reminder, auto-deletes after firing{"name":"openclaw_cron_add_once","arguments":{"name":"remind-meeting","at":"2026-12-25T09:00:00+01:00","message":"Don't forget the holiday call."}}
All four take the standard knobs: agentId?, model?, timeoutSeconds? (default 900), channel? + to?, deliveryMode? (announce | direct | none), instance?.
Tools
143 typed tools wrapping the 128 JSON-RPC methods the gateway publishes (and 2 standalone introspection tools). Run openclaw_introspect once paired to see the live list of methods + events on your specific gateway.
Introspection (no scopes required)
Tool
Notes
openclaw_introspect
Returns server version, your role/scopes, and the full methods[] / events[] list the gateway publishes in its hello-ok.
openclaw_call
Escape hatch β call any JSON-RPC method with arbitrary params. Useful when the gateway adds new methods between releases. Prefer typed wrappers when they exist.
Setup (no scopes required)
Tool
Notes
openclaw_setup
Persist { gatewayUrl, gatewayToken, gatewayPassword? } to local config.
openclaw_setup_show
Report effective config (env vs store), without printing tokens.
openclaw_setup_clear
Wipe persisted gateway config. Device identity + tokens are kept.
Device & pairing (device.pair.*, device.token.*)
openclaw_device_status / openclaw_device_pair_list / _pair_approve / _pair_reject / _pair_remove / openclaw_device_token_revoke / _token_rotate. Manages your local Ed25519 identity and the per-gateway tokens it's been issued.
Coverage by domain (require operator.read / operator.write / operator.admin)
These carry destructive side effects (data loss, service interruption, revoked access). Their description is marked accordingly so Claude Code's confirmation gate prompts before each call:
Self-update: update_run (gateway-wide, may interrupt sessions)
Examples
Copy-paste prompts you can drop into Claude after the MCP is paired. Each one targets the corresponding tool and shows the kind of natural-language phrasing that resolves to a concrete call.
Health & sanity
code
> Run a full openclaw health check.
β Calls openclaw_health, reports MCP version, gateway server version, paired device fingerprint, granted scopes, and how recently the last successful call ran.
code
> What gateway methods do I have access to right now?
β Calls openclaw_introspect, returns the 128 JSON-RPC methods + 24 events the gateway publishes in its hello-ok.
Cron
code
> List all openclaw cron jobs, including disabled ones.
β openclaw_cron_list({ enabled: "all" }).
code
> Show me the last 5 runs of cron job <id> β compact mode, just the summaries.
β openclaw_cron_runs({ id: "<job-id>", limit: 5, compact: true }) β summaries truncated to 200 chars, each entry gets a runAtAgo: "3d ago" field.
code
> Create a cron that runs every Friday at 1pm Paris and posts a summary to Telegram group -1001234567890.
β Generates an openclaw_cron_add payload with the right schedule.kind: "cron", expr: "0 13 * * 5", tz: "Europe/Paris", and delivery.mode: "announce".
Sessions
code
> List the 10 most recent active openclaw sessions, ranked by last activity.
> Show me the last 8 messages of session agent:main:cron:<id>.
β openclaw_sessions_preview({ keys: ["agent:main:cron:<id>"] }) β returns role/text turns straight from the gateway.
Agents & channels
code
> List the agents configured on this gateway and which model they use.
β openclaw_agents_list.
code
> What's the connection state of my Telegram channel?
β openclaw_channels_status.
Escape hatch
code
> Use openclaw_call to invoke "config.schema" with no params and return the keys it exposes.
β Useful when a gateway-side method doesn't yet have a typed wrapper, or you want to inspect a feature still in beta.
Resilience
request() retries transient errors (network drop, ws close, timeout, DNS) with exponential backoff: defaults to 1s β 2s β 4s, max 4 attempts. Non-retryable errors (PAIRING_REQUIRED, INVALID, MISSING_SCOPE, etc.) fail fast β no point retrying a permission issue. Tune via:
OPENCLAW_RETRY_ATTEMPTS β total attempts (default 4, range 1β10)
OPENCLAW_RETRY_BASE_MS β initial backoff in ms (default 1000, range 100β60000)
OPENCLAW_DEBUG=1 β prints every retry decision to stderr
When a request gives up, the thrown error carries gateway request '<method>' failed (attempt N/M): as a prefix and the original error is preserved as cause for inspection. GatewayErrorcode / details / retryable flags are propagated through the wrap.
The client tracks lastSuccessAtMs for openclaw_health's lastSuccessAgo field β useful for "is the gateway still talking to me?" debug.
Diagnostic CLI
For one-shot health checks without wiring the MCP into a client:
bash
npx -y openclaw-control-mcp --health
Prints a JSON report (MCP version, gateway URL, paired state, scopes, server version, last-success age, error if any) and exits non-zero on failure. Handy in CI / scripts.
Schema looseness
Most v0.3.0 wrappers use z.passthrough() for params β they accept the documented fields plus anything else, and pass them through to the gateway. This trades strict client-side validation for forward-compat: as the gateway evolves, calls don't break on new fields. The downside is you'll only learn about a wrong field when the gateway rejects the request. If you hit a "missing required property" error, look at the gateway's response β it tells you the exact wire shape β and either correct your call, or open an issue / PR to tighten the wrapper's Zod schema.
Threat model
This MCP server exposes secret-bearing and side-effectful gateway operations (config.*, secrets.*, cron.run, sessions.send, agent, channel send) to an LLM that the operator drives via natural language. Treat that surface deliberately:
The gateway token, device private key, and per-gateway device tokens are persisted under ${XDG_CONFIG_HOME:-~/.config}/openclaw-control-mcp/store.json (file mode 0600). Since 0.8.0 the server never touches your OS keychain β no security / secret-tool call, no permission prompt. If you'd rather no secret was written to disk by the server at all, supply them via a .env file instead (see Secrets & the .env file). Never commit the store or the .env, and don't post --health output unredacted.
openclaw_secrets_set writes into the gateway config tree via config.patch. Any tool call that reaches this wrapper rotates the underlying secret in the gateway's view. Wrap it with explicit human confirmation in agent prompts.
openclaw_call is an escape hatch β it forwards arbitrary JSON-RPC method calls. The gateway enforces per-scope permissions, but on the client side there's no input filter. Limit which tool catalogs your agent can see if untrusted prompts can reach it.
OPENCLAW_DEVICE_PRIVATE_KEY / OPENCLAW_DEVICE_TOKEN env vars (for headless / CI / service-account usage) take priority over the store. Set them only in trusted execution contexts (GitHub secrets, K8s secrets, password manager exports, a chmod 600.env β never in shell history, Docker --env, or a .env committed to a repo).
Prompt-injection surface: the gateway's responses (session previews, logs, agent outputs) feed back into the MCP client and can carry attacker-controlled content. Treat any tool output as untrusted when deciding whether to call destructive tools (the destructive list is published in Β§Destructive tools β confirm before chaining a write tool to a read tool output).
HTTP transport surface: when running --http, the server enforces a constant-time Bearer check if OPENCLAW_HTTP_BEARER is set, refuses to bind to a non-loopback interface without one, and emits a loud stderr warning if started on loopback without one. Rotate the bearer like a gateway admin token β anything that can read it can invoke every tool, including secrets.* writes. Terminate TLS at a reverse proxy before exposing the HTTP port to the network.
Auto-reconnect with backoff (currently single-shot β Claude Code respawns the stdio process on demand).
Stream session messages back into the MCP client (currently sessions.subscribe registers server-side but stdio can't surface deltas to Claude Code).
Tighten Zod schemas for the wrappers added in 0.3.0 β most use passthrough() until the gateway shape for each domain is fully nailed down. PRs welcome.
HTTP / SSE transport in addition to stdio, to enable Cursor remote and Claude.ai web custom-connector use.
Claude Desktop Extension (.mcpb) packaging.
Migrating from openclaw-claw-mcp (early adopters)
If you used the wrapper under its previous name (openclaw-claw-mcp):
The Store automatically reads ~/.config/openclaw-claw-mcp/store.json as a fallback when the new path is empty, so your paired device token keeps working.
On the next successful connect, the new path (~/.config/openclaw-control-mcp/store.json) is created. You can then delete the old directory.
Update the entry name in ~/.claude.json from openclaw-claw to openclaw-control (purely cosmetic β only changes the tool prefix mcp__openclaw-control__*).
The local working dir / build output keeps the same path you cloned to; nothing else needs moving.
Troubleshooting
gateway request 'β¦' failed: expected Uint8Array of length 32, got length=0 β the persisted device.privateKey is empty. On 0.8.0+ the usual cause is an upgrade from 0.5.0β0.7.0 where the key still sits in the OS keychain: run npx -y openclaw-control-mcp --migrate-from-keychain once. Otherwise recover with openclaw_device_repair. Background: docs/troubleshooting/empty-private-key.md.
gateway request 'β¦' failed: device nonce mismatch after some idle time β the WS connection went stale and the retry loop reuses a burned nonce. Workaround: re-call openclaw_setup with the same params (forces a fresh handshake). Details + proposed fixes: docs/troubleshooting/stale-connection-nonce-mismatch.md.
Caveats
The protocol is reverse-engineered, not documented. Behaviour may change with gateway updates.
The connect frame matches what openclaw/openclaw/scripts/dev/gateway-smoke.ts sends today (client.id: "openclaw-ios", mode: "ui", role + scopes per the iOS operator default). Different client.id values trigger different server policies β openclaw-control-ui and openclaw-tui for example require device identity and a secure-context origin.
OPENCLAW_DEBUG=1 logs every WS frame to stderr (truncated at 8 KB). Useful when comparing handshakes against the live Control panel SPA.
