engrail-therapeutics-mcp.yml
engrail.com runs two live Model Context Protocol servers on its WordPress-backed corporate site, registered under the `mcp` REST namespace and fronted by RFC 8414 / RFC 9728 OAuth discovery documents at the apex. Both servers are OAuth-protected: an anonymous `tools/list` returns HTTP 401 (`mcp_unauthorized` on the OAuth server, `rest_forbidden` on the adapter default server), so the live tool manifest and its inputSchemas could not be read and NO tool list is recorded here. The companion WordPress Abilities API (`wp-abilities/v1`), which is what backs MCP tools on this plugin stack, is likewise 401 for anonymous callers. This is a real, discoverable agent surface on a clinical-stage pharmaceutical company's marketing site — not a product API.
One-click install for Cursor, VS Code, Claude, and 20+ other MCP clients, powered by API Commons MCP Install — visit install.apicommons.org for more information.

About MCP
The Model Context Protocol (MCP) is an open protocol Anthropic introduced for connecting LLM-based agents to external tools and data sources. Providers publish MCP servers that expose their API surface as structured, discoverable tools — an MCP-compatible client (Claude Desktop, Cursor, Cline, Continue, etc.) can connect to the server and call its tools without any per-provider integration code.
Browse every MCP server on the APIs.io network or compare with the broader Agent Skill surfaces of the same providers.
