Lets an assistant search and monitor ClinicalTrials.gov and EU clinical trial registry records, including tracking changes to trials.
What you can do
This remote MCP server connects an assistant to clinical trial registry data. According to its description, it supports searching and monitoring records from ClinicalTrials.gov and EU trial registries, and it tracks changes to those trial records over time. No individual tools are listed in the supplied manifest, so the exact operations available are not documented here.
When to use it
Consider it when an assistant needs to look up clinical trial records or keep an eye on updates to trials in the US or EU registries. It is aimed at research, monitoring, and registry-tracking workflows rather than general web search.
Requirements
It runs as a remote streamable HTTP endpoint at clinicaltracker.org, so no local runtime or package install is needed. The manifest declares no authentication, environment variables, or headers, and no accounts or API keys are documented.
Before you install
The manifest declares no authentication, so it is unclear what data or rate limits apply, and no credentials are described. The description mentions change tracking, but it does not state whether the server only reads registry data or also writes anything. Verify the provider's terms and privacy practices before relying on it.
Enable the server for the chats that should use its tools.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Use with an agent
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/io.github.agentstructure%2Fclinical/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.
Search ClinicalTrials.gov by condition, intervention, sponsor, phase, recruitment status, location, institution, study type or dates. Returns structured studies with source links and retrieval time.

get_clinical_trial
Get a clinical trial
One study by NCT id: full structured record (status, dates, enrollment, eligibility text, sites and contacts, outcomes, documents), plus the changes AgentStructure has observed and data freshness.
The change history AgentStructure recorded for a study: previous and new values, event type, dates and provenance. Starts monitoring the study if it was unknown.
Side-by-side registry attributes for 2 to 5 studies. A structural comparison only, never an efficacy or safety ranking.

Search EU clinical trials
Search the EU Clinical Trials Information System (CTIS, euclinicaltrials.eu) by condition, medicine, sponsor or text, or get one trial by EU CT number (with its ClinicalTrials.gov link when listed). Experimental source.
A source-linked brief on a study, sponsor, condition, intervention, or one of your watchlists: current facts, observed developments, unknowns, and freshness.
