Overview
Provides an n8n community node that acts as an MCP (Machine-readable Capability Protocol) server, dynamically generating and exposing tools from an OpenAPI specification URL via a webhook for API integration.
Installation
No command providedSecurity Notes
The server's core functionality involves fetching external OpenAPI specifications from a user-provided `openapiUrl` and making requests to external APIs defined by a user-provided `baseUrl` and the OpenAPI spec. While crucial for its operation, this introduces potential for SSRF (Server-Side Request Forgery) if the n8n instance is configured by an untrusted user and its network egress is not restricted. Input parameters for API calls are generally sanitized (e.g., `encodeURIComponent` for URL parts, `JSON.stringify` for bodies), mitigating common injection risks within the HTTP requests themselves. No `eval` or code obfuscation is present. The code appears well-structured and focuses on its stated purpose.
