It is distributed as grok-build-mcp-server on npm, filed under Other by this index, and declares 9 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 Grok Build 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 2026-08-18).\n\nContracts can change after screening, with no version bump. The gate pins Grok Build’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`GROK_BINARY`\n\nPath to the grok executable. Only needed when grok is not on PATH.\n\n`GROK_MCP_PERMISSION_CEILING`\n\nHighest permission level any call may request. Granted once at registration and never prompts again.\n\n`GROK_MCP_DEFAULT_PERMISSION`\n\nPermission level used when a call specifies none. Must be at or below the ceiling.\n\n`GROK_MCP_DEFAULT_MODEL`\n\nModel used when a call omits one.\n\n`GROK_MCP_DEFAULT_EFFORT`\n\nReasoning effort used when a call omits one.\n\n`GROK_MCP_TIMEOUT_MS`\n\nWall-clock kill for a single run, in milliseconds.\n\n`GROK_MCP_STATE_DIR`\n\nDirectory for background job records. Defaults to $XDG_STATE_HOME/grok-mcp.\n\n`GROK_MCP_MAX_CONCURRENT_RUNS`\n\nBackground runs alive at once. Use off, none, or unlimited for no cap.\n\n`STRUCTURED_CONTENT_ENABLED`\n\nEmit structuredContent alongside _meta. Off by default because some clients mishandle it.\n\n[methodology](/methodology)\n\n[ConnectMachineai.connectmachine/connectmachine](/server/ai-connectmachine-connectmachine)\n\nManage your ConnectMachine contacts, networks, events, and digital business cards.\n\n[DABLOCK AI Visibility Indexai.dablock/visibility-index](/server/ai-dablock-visibility-index)\n\nMeasured share of answer for 24 crypto and Web3 brands.
