It is distributed through a declared package, filed under Memory & RAG by this index, and declares 3 environment variables. Removals and unreachable sources are measured across every server this index tracks, contract drift across the servers that answer in consecutive snapshots; [the index's current counts](/stats) put this record in context.\n\n## Using KMP in Claude, Cursor, Gemini CLI, Cline, or Zed?\n\nMCP tool contracts can change remotely with no version bump. The mcpindex gate pins each contract and **HOLDs the call** when it drifts-before your agent acts. Zero credentials. This is not the package install for this server itself (use **Install this server** for that).\n\nRewrites your MCP host config so each server launches behind the gate. Inspect first: curl -fsSL https://mcpindex.ai/install.sh | less\n\n```\nuv tool install mcpindex-gate && mcpindex-config-wire\n```\n\n[method](/methodology)\n\nVerdict not yet evaluated for this tool. The semantic screen takes adversarial cases first; coverage rolls out as the corpus expands (15/150 labels to graduation). The deterministic conformance probe is built but has not yet run on the public corpus, so a recorded verdict here is REVIEW or UNVERIFIED, never a clearing ALLOW. Until a verdict is recorded, an agent should treat this tool as not-yet-cleared and fall back to its own checks. Method: [the eval, four-state verdict, honest limits](/methodology).\n\nOwn this server? [Screen its description →](/screen)\n\n## That verdict was true at screening time (snapshot 2026-08-29).\n\nContracts can change after screening, with no version bump. The gate pins KMP’s tool contracts on first sight and holds any silent change before your agent acts - the check that keeps being true on Tuesday.\n\n[See your first HOLD in 2 minutes →](/guides/install-the-gate-first-hold)\n\nRelated: [how to trust an MCP server](/guides/how-to-trust-an-mcp-server) · [screen before install](/guides/screen-mcp-server-before-install) · [silent contract drift](/guides/mcp-silent-contract-drift)\n\n`KMP_MCP_DATA_DIR`\n\nOptional memory directory; otherwise KMP uses the project or per-user default\n\n`KMP_VIEWER_ADDR`\n\nOptional viewer address, or off to disable the local viewer\n\n`KMP_KERNEL_GRPC_ENDPOINT`\n\nOptional remote KMP endpoint; omit it to keep the kernel in this process\n\n`KMP_MCP_DATA_DIR`\n\nOptional memory directory; otherwise KMP uses the project or per-user default\n\n`KMP_VIEWER_ADDR`\n\nOptional viewer address, or off to disable the local viewer\n\n`KMP_KERNEL_GRPC_ENDPOINT`\n\nOptional remote KMP endpoint; omit it to keep the kernel in this process\n\n[methodology](/methodology)\n\n[Fodda Knowledge Graphsai.fodda/mcp-server](/server/ai-fodda-mcp-server)\n\nExpert-curated knowledge, brand, research & earnings intelligence — 47 tools, 220+ graphs.\n\n[Achriomcom.achriom/achriom](/server/com-achriom-achriom)\n\nMedia memory for AI agents and their humans: books, movies, music, shows, anime, podcasts, games.\n\n[unerrio.github.unerr-ai/unerr](/server/io-github-unerr-ai-unerr)\n\nOperational memory for AI agents: code graph, session memory & guardrails.
