n8n-mcp-server-rust

Provides an MCP server (implemented in Rust) that exposes n8n functionality such as managing executions, workflows, and tags, and can trigger running a workflow (notably one with a webhook-trigger node).

Best When

You already run (or can run) an MCP client that can call tools and you want programmatic n8n control via those MCP tool methods.

Avoid When

You cannot verify authentication, transport security requirements, or operational limits from documentation; avoid deploying without reviewing the repository code/docs for these aspects.

Use Cases

  • Connect an AI agent to n8n for workflow and tag management
  • Perform operational tasks such as listing/deleting executions and CRUD for workflows/tags
  • Automate n8n workflow runs from an MCP-capable orchestration/agent environment

Not For

  • Direct end-user use without an MCP client/orchestrator
  • Use cases requiring strong, explicitly documented security/credential handling guarantees (not provided in the provided README)

Known Gotchas

  • The provided README lists tool capabilities but does not document pagination, filtering, timeouts, rate limits, or idempotency semantics; agents may need to handle these carefully.
  • “Run a workflow” implies specific n8n setup (webhook trigger node); if the workflow does not meet requirements, tool calls may fail without clear guidance.
