The in-path trust gate for agent tool calls.
What can you do with mcpindex?
mcpindex.ai
The in-path trust gate for agent tool calls.
MCP tool contracts can change remotely with no version bump. mcpindex pins each contract and HOLDs the call when it drifts — before your agent acts. Deterministic contract-diff on your host. Zero credential custody. Not a safety oracle.
Live site · Install gate · npx mcp-server-mcpindex · pip install mcpindex-gate · Remote MCP · Docs · Trust · Methodology
What you get
- In-path drift gate — one command wires Claude Desktop / Claude Code / Cursor / Gemini CLI / Cline / Zed so each MCP server launches behind the gate. Local, fail-closed, default build egresses nothing.
curl -fsSL https://mcpindex.ai/install.sh | sh(inspect first with| less) · PyPI:mcpindex-gate - Advisory directory — search, recommend, preflight (
/api/v1/preflight), and trust lookups over HTTP or as a drop-in MCP server (mcp-server-mcpindex). Screen verdicts are REVIEW / UNVERIFIED at v1; ALLOW / DENY are reserved in the contract. - Agent-readable surfaces —
/llms.txt,/.well-known/mcp-index.json, JSON-LD, and a per-server page for every indexed server (live count at mcpindex.ai/stats).
The gate is the wedge. The directory is the corpus the gate can query — also free.
