ClinicalTrials.gov Data API v2 (candidate MCP surface)

A CANDIDATE tool list derived from the ClinicalTrials.gov Data API v2 OpenAPI operations. The National Library of Medicine does not publish an MCP server for ClinicalTrials.gov — no hosted endpoint, no NLM-owned package, and no reference to MCP anywhere on clinicaltrials.gov/data-api. Nothing here is an endpoint an agent can call today.

⚠ Proposed MCP surface. No official hosted MCP server was found for ClinicalTrials.gov. The tools below are a candidate set derived from this provider's API, and the link points at the source descriptor rather than a live server. If ClinicalTrials.gov publishes an official server, this page will update to it on the next build.

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.

Work with this as data

Every MCP server here is available over the APIs.io API and to AI agents over MCP.
