Standalone MCP directory — 61862 servers across 36145 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 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 61862 indexed servers, of which 53021 answered within the last 6 h.

  • uptime_30d 1.0%; p95 156.1ms; conformance: fail

  • Scan any public GitHub MCP-server repo for security issues. 37 MCP-specific L1 rules, 8 languages.

  • Static security scanner for MCP servers. POST a public GitHub URL, get severity counts, a score, and the top findings with file+line back. 37 rules across TypeScript, JavaScript, Python, Go, Rust, C#, Java, and Kotlin — every language with an official MCP SDK. Detects argument injection for npx/uvx/pipx/pnpx runner binaries (CWE-88), known CVEs in 40+ top packages, and the usual L0 discovery (transport, tool inventory, dependency pinning). This is a pattern detector, not an exploitability oracle. Around 90% raw false-positive rate on unfiltered output — triage is on you, and the response says so explicitly. POST /v1/scan is free with no API key. POST /v1/scan/pay charges $0.10 USDC per scan via x402 on Base. Manual L2-L4 audits at compuute.se/audit when you need dataflow review. Wraps compuute-scan (MIT, zero deps). Per-rule false-positive rates and the methodology paper live in the repo.
