@letmepost/mcp

MCP server for letmepost.dev. Lets AI agents drive the full publishing API — posts, media, accounts, webhooks, API keys — through one MCP connection. The tool surface is generated from the canonical OpenAPI spec at startup, so every documented endpoint is reachable without a bespoke wrapper.

Install

npx @letmepost/mcp

Or wire it into Claude Code:

claude mcp add letmepost npx @letmepost/mcp --env LMP_API_KEY=lmp_live_...

Cursor / Cline / any MCP client:

{
  "mcpServers": {
    "letmepost": {
      "command": "npx",
      "args": ["@letmepost/mcp"],
      "env": { "LMP_API_KEY": "lmp_live_..." }
    }
  }
}

Configuration

Tools

Tool names follow {method}_{path} with {param} segments rewritten as by_{param}. The current surface, generated from the OpenAPI spec:

• post_v1_posts — Publish or schedule a multi-target post. One call fans out to up to 25 connected accounts.
• get_v1_posts — List posts with cursor pagination, filterable by platform, status, error code, and time window.
• get_v1_posts_by_id — Fetch a single post with all its publish attempts.
• get_v1_media — List uploaded media. (Upload itself is multipart-only and exposed via the REST API; the MCP surface stays JSON-only.)
• get_v1_accounts, get_v1_accounts_by_id, delete_v1_accounts_by_id — Read and disconnect platform accounts.
• post_v1_accounts_connect_by_platform, post_v1_accounts_connect_by_platform_complete — Drive the connect handshake.
• get_v1_accounts_by_id_pinterest_boards, post_v1_accounts_by_id_pinterest_boards, patch_v1_accounts_by_id_pinterest_default_board — Pinterest board lifecycle.
• post_v1_api_keys, get_v1_api_keys, delete_v1_api_keys_by_id — Mint / list / revoke API keys.
• post_v1_webhook_endpoints, get_v1_webhook_endpoints, get_v1_webhook_endpoints_by_id, patch_v1_webhook_endpoints_by_id, delete_v1_webhook_endpoints_by_id, post_v1_webhook_endpoints_by_id_test — Outbound webhook management.

Each tool's inputSchema is a flat JSON schema with path / query / body fields merged into one object — the agent doesn't need to know which slot a field lives in. Idempotency keys are auto-injected on writes.

Self-host

Self-host bypasses every platform approval gate. Bring your own credentials, every platform works the day you clone the repo. See docs.letmepost.dev/self-host/quick-start.
