# ai.partsgraph/catalog (ai.partsgraph/catalog@1.2.0) > Source: > Published: 2026-08-19 22:27:01+00:00 [← Index](/leaderboard) # ai.partsgraph/catalog Search real parts with datasheet-provenance specs, check compatibility and compose priced BOMs. The current version, v1.2.0, was published to the official MCP registry on 2026-08-19. It is distributed as a hosted remote over streamable-http, filed under Search by this index. 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. ## Using ai.partsgraph/catalog in Claude, Cursor, Gemini CLI, Cline, or Zed? MCP 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). Rewrites your MCP host config so each server launches behind the gate. Inspect first: curl -fsSL https://mcpindex.ai/install.sh | less ``` uv tool install mcpindex-gate && mcpindex-config-wire ``` [method](/methodology) Verdict 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). Own this server? [Screen its description →](/screen) ## That verdict was true at screening time (snapshot 2026-08-19). Contracts can change after screening, with no version bump. The gate pins ai.partsgraph/catalog’s tool contracts on first sight and holds any silent change before your agent acts - the check that keeps being true on Tuesday.
