This one has been quiet for a while
Quiet is not dead — but it is worth knowing when it wakes up, or when someone else takes it over. We watch the repository and tell you either way.

Endpoint below is the one we actually reach during checks — not the one copied from a README. Last verified 6 min ago.

}This one needs environment variables set before it will start:
CLAIDEX_MCP_URL (Claidex MCP endpoint URL.), CLAIDEX_MCP_API_KEY (Claidex API key for protected tools and resources.).
The author declared them in the registry entry; get the values from the project itself.
This endpoint answered with an authorization challenge. The server is running, but it did not say what kind of credentials it expects.

query_clinicaltrials
Search ClinicalTrials.gov for clinical trials. Can search by drug name, condition, target, or NCT ID. Returns trial status, phase, sponsor, primary endpoints, and why_stopped if terminated.
computation
run_computation
Evaluate deterministic mathematical expressions with optional variables. Use for algebra, matrices, vectors, transformations, descriptive numerical checks, and reproducible calculations. Does not execute arbitrary JavaScript or install packages.
consult
consult_specialist_model
Ask a specialist Gateway model for code, database/tool-calling, statistics, literature, preprint, or mechanistic synthesis support. Use for hard subproblems, second opinions, code generation/review, or complex synthesis.
failure
query_failure_graph
Query the Claidex failure graph for a specific gene target. Returns the Mechanism Risk Score (MRS), failure counts by phase and archetype, and all related claim slugs.
fetch
fetch
Fetch a specific result returned by search. This compatibility tool supports OpenAI and ChatGPT remote MCP retrieval flows.
openfda
query_openfda
Query the FDA FAERS database for adverse event signals for a drug. Returns top adverse event terms, serious case count, and death count.
opentargets
query_opentargets
Query Open Targets for target-disease association evidence. Returns genetic evidence score, clinical evidence, known drugs, tractability, and safety liabilities for a gene-disease pair.
package
query_package_registry
Look up package metadata from npm or PyPI before recommending code, analysis packages, API clients, or dataset tooling.
preprint
search_preprint_flags
Search the Claidex Preprint Watch database for bioRxiv preprints flagged as contradicting the clinical failure record. Search by target gene, disease, or preprint title.
pubmed
search_pubmed
Search PubMed for biomedical literature. Returns title, authors, journal, year, DOI, abstract, and PMID for each result.
rank
rank_documents_by_embedding
Embed a query and candidate documents, then rank documents by cosine similarity. Use for semantic matching, retrieval checks, clustering triage, and lightweight RAG over user-provided passages.
rerank
rerank_documents
Rerank candidate documents/passages against a query using a dedicated reranking model. Use after retrieval/search when exact relevance ordering matters.
research
fetch_research_url
Fetch a public HTTPS research URL, JSON API response, package metadata endpoint, documentation page, or dataset preview. Blocks private/internal hosts and truncates large responses.
search
search
Search Claidex failure claims and preprint flags. This compatibility tool returns citation-ready results for OpenAI and ChatGPT remote MCP flows.
statistical
run_statistical_analysis
Run a statistical analysis computation. Supports: Wilson confidence intervals, binomial proportions, phase transition success rates, power calculations, Bayesian posterior estimates, descriptive statistics, and two-proportion comparisons. Returns computed values, interpretation, and LaTeX formula.
web
web_search
Search the web for recent news, investor commentary, analyst notes, press releases, and conference coverage about drugs, clinical trials, or biomedical mechanisms.

Claidex MCP — questions
Answers built from our own checks of this server.
What can Claidex MCP do?
It exposes 24 tools, read directly from the server on our last check. Among them: claidex_capabilities, claidex_claim_risk_matrix, claidex_health_snapshot, claidex_research_prompt, claidex_tool_catalog, consult_specialist_model and 18 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README.
How MCP servers expose tools in the first place →
Is Claidex MCP working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 141 ms. The bar chart above shows every period we have measured.
Is Claidex MCP still maintained?
The linked repository no longer exists on GitHub — it was deleted or made private. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.
How do I connect Claidex MCP?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address. You will need your own credentials: it refuses anonymous clients.
Does Claidex MCP need an API key?
Yes. Every time we knock, Claidex MCP answers with an authorization challenge instead of its tool list — that is how we know it is running and gated rather than broken. Bring your own credentials and it will talk.
How fast is Claidex MCP?
It answers our handshake in 141 ms on average, which is faster than 78% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
How many people use Claidex MCP?
The npm package @claidex-mcp/claidex-mcp was installed 33 times in the last week. Week over week that is +29%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
