Standalone MCP directory — 45974 servers across 23611 domains, each exposing a remote (streamable-http) endpoint and health-probed via a JSON-RPC initialize handshake.

Add your server

Aggregated from the official MCP Registry, Smithery, PulseMCP and other public registries, plus our own crawling and operator submissions. Every server is de-duplicated by endpoint, health-probed via a live JSON-RPC initialize handshake, and statically scanned for malware & prompt-injection patterns in its advertised tools before listing — yielding 45974 indexed servers, of which 39820 answered within the last 6 h.

  • DevMatch is an MCP server for hiring engineers based on what they've actually built. Connect from Cursor, Claude Desktop, or any MCP-compatible AI assistant and search 35M+ developers ranked by verified open-source contributions — not LinkedIn keywords or self-reported skills. **Three tools:** **`find_candidates`** — paste a job description, get a ranked shortlist with bio, top repos, contribution evidence, and contact info. Pro tier adds verified email enrichment on the top 5 results. **`get_profile`** — deep-dive any GitHub handle. Bio, recent activity, top projects, and outreach channels in one call. **`find_similar_projects`** — landscape mapping from a seed repo with top contributors surfaced, so you can pivot from a project to its maintainers in one step. Built for mission-driven teams that want engineers who care about the work, not just check the keyword box. OAuth sign-in (no API keys to juggle). Free tier with 50 monthly credits, $129/mo Pro for higher quotas plus verified email enrichment.

  • uptime_30d 1.0%; p95 341.9ms; conformance: fail

  • Diagnoses, drugs & lab codes: ICD-11, LOINC, RxNorm, MeSH, ATC, CID-10. 33 tools, MIT.

  • Unified MCP server for six medical terminologies — ICD-11, LOINC, RxNorm, MeSH, ATC and the Brazilian CID-10 (Portuguese) — with authoritative WHO ICD-10→ICD-11 mapping, cross-terminology search and provenance (source, version, timestamp) on every response. Read-only retrieval, not clinical decision support. Remote (Streamable HTTP, no auth, no credentials) or local stdio.

  • Unified MCP server giving LLMs and AI agents reliable lookup access to seven medical terminology systems — instead of inventing codes, the model queries the same APIs that WHO, NLM, and NIH publish for clinical and research use. **Terminologies covered:** - **ICD-11** — WHO's current International Classification of Diseases - **LOINC** — laboratory observations and clinical measurements (NLM) - **RxNorm** — normalized drug nomenclature (NIH) - **MeSH** — Medical Subject Headings for PubMed search refinement (NLM) - **ATC** — Anatomical Therapeutic Chemical classification (via NLM RxClass) - **CID-10** — Brazilian Portuguese ICD-10 (bundled DataSUS V2008) - **SNOMED CT** — optional, license-gated (requires a self-hosted Snowstorm endpoint) **Highlights:** - **37 tools** across search, lookup, hierarchy navigation, batch validation, and cross-terminology mapping - **Authoritative WHO ICD-10 → ICD-11 mapping** via bundled transition tables (release 2025-01, 11,243 categories — 1,461 with documented alternatives) - **Cross-terminology batch validator** flags codes that no longer exist and surfaces ICD-10 → ICD-11 replacements - Tool responses include both human-readable text and `structuredContent` matching a published `outputSchema` (for tools whose results are structured) - Per-tool `language` parameter on SNOMED, ICD-11, and MeSH for multilingual workflows - **Hosted Streamable HTTP endpoint** at `medical-terminologies-mcp.sidneybissoli.workers.dev/mcp` — no install required - TypeScript / Node 20+, OAuth2 with proper `expires_in` handling, token-bucket rate limiting (5/10/20 req/s per API), exponential backoff with jitter, 313 unit + contract tests gating CI, daily live-API integration cron - **MIT licensed** **Audience:** clinical informaticians, biomedical researchers, public-health analysts, EMR integrators, and developers building agentic workflows around medical coding. This is a lookup layer, not a clinical decision tool.
