Arclan MCP Registry

MCP server registry — validated by live handshake, scored on reliability, monitored continuously.

MCP server registry with live validation and continuous reliability monitoring.

Captured live from the server via tools/list.

query_registry

Search the Arclan registry for MCP servers. By default returns only connectable servers (active, mcp_partial, auth_gated). Use status=stdio to browse local-only servers available for installation. Use status=all to query the full index. Use production_safe=true to restrict to servers with uptime > 97% and handshake success > 95%. Use read_only=true to restrict to servers with no write or exec tools. Use this before connecting to an MCP server to check its validation status and score. After using a server, call report_server to contribute reliability data.

Parameters (7)

capabilitystring
Filter by tool name or keyword (searches name, description, tools)
min_scorenumber
Minimum validation score 0–100 (default 0)
transportstring
Filter by transport type
statusstring
Filter by state. Default (omit): connectable states only (active + mcp_partial + auth_gated). Use "stdio" for local-install catalog. Use "all" for the full index.
production_safeboolean
Only return servers with uptime_7d > 97% and handshake_success_rate > 95%. Use when reliability matters.
read_onlyboolean
Only return servers with no write or exec tools — safe for read-only agent workflows.
limitnumber
Max results to return 1–20 (default 10)

get_server

Get full details for a specific MCP server. Pass the server name (e.g. "GitHub", "Brave Search"), registry ID slug, or endpoint URL. Returns score, state, tools list, latency, and recent test history.

Parameters (2)

urlstring
The MCP server endpoint URL (e.g. "https://mcp.example.com/mcp")
idstring
Server name, registry ID slug, or any identifier (e.g. "github", "brave-search", "gateway-pipeworx-io-rpc-mcp")

recommend_server

Get ranked MCP server recommendations for a task. Returns servers scored by production safety, keyword relevance, registry score, latency, and freshness. Each result includes a reason code array explaining why it was ranked. Use this instead of query_registry when you want an opinionated ranked list rather than a filtered search.

Parameters (5)

qstring
Task or capability query — e.g. "search the web" or "read files"
authboolean
Include servers that require authentication (default: true)
production_safeboolean
Only return production-safe servers (uptime > 97%, handshake > 95%)
read_onlyboolean
Only return servers with no write-classified tools
limitnumber
Max results 1–20 (default: 5)

report_server

Submit an agent usage report for an MCP server. Reports are aggregated and influence registry trust scores. Call this after using an MCP server so the registry can track real-world reliability. Supports both a simple outcome report and a structured scoring report (criterion + component_score).

Parameters (14)

serverUrlstringrequired
The MCP server endpoint URL that was used
outcomestringrequired
Result of using the server
agentIdstring
Identifier for the reporting agent (optional)
toolsUsedarray
List of tool names that were called
turnsRequirednumber
Number of turns to complete the task
latencyMsnumber
Total wall-clock latency in milliseconds
taskCategorystring
Category of task attempted (e.g. "search", "write", "read")
taskDescriptionstring
Brief description of what the task was
errorsarray
Array of error strings encountered during tool use
criterionstring
Specific reliability criterion being scored (enables structured component scoring)
componentScorenumber
Score 0–100 for the specified criterion
severitystring
Severity of the worst issue encountered
environmentstring
Environment the server was used in
evidenceRefstring
Trace ID, log URL, or other reference supporting this report
