Returns source-bearing results from Groundlink.\n\nThe current version, v0.1.1, was published to the official MCP registry on 2026-08-22. It is distributed as groundlink-mcp on npm, filed under Search by this index, and declares one environment variable. 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 Groundlink 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 2026-08-22).\n\nContracts can change after screening, with no version bump. The gate pins Groundlink’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`GROUNDLINK_API_KEY`\n\nGroundlink API key used for every cited web-search request.\n\n[methodology](/methodology)\n\n[YTDL RMCPai.dinglebear/rytdl](/server/ai-dinglebear-rytdl)\n\nyt-dlp search, download, metadata, delivery, and Plex workflows over MCP and CLI.\n\n[Fodda Topic & Trend Researchai.fodda/topic-research](/server/ai-fodda-topic-research)\n\nTrend, stats & insight search across PSFK expert graphs with citable sources.\n\n[MediaWikiio.github.olgasafonova/mediawiki-mcp-server](/server/io-github-olgasafonova-mediawiki-mcp-server)\n\nSearch, read, and edit any MediaWiki wiki.
