# pg-aiguide — AI Connector pg-aiguide publishes 2 MCP tools to Claude. Marketplace availability, tool surface, verification tier, and what Node8 measured against the live endpoint. Source: https://node8.ai/ai-connectors/developer-tools/pg-aiguide/ --- [AI Connectors](https://node8.ai/ai-connectors/) · [Developer Tools](https://node8.ai/ai-connectors/developer-tools/) # pg-aiguide Postgres and TimescaleDB documentation with authoring skills Listed in Claude · 2 published tools · Verified partner [Claude connector docs](https://github.com/timescale/pg-aiguide) [tigerdata.com](https://tigerdata.com) Overview ## What pg-aiguide does Tiger Data publishes this server to improve the Postgres output of a coding agent. It carries two things: documentation, searched with a hybrid of vector similarity and BM25 keyword matching, and a set of skills describing TimescaleDB operations and the practices around them. The distinction between the two matters. Documentation answers what a function does; the skills describe how to do something correctly, which is usually where a model writing SQL from memory goes wrong. The endpoint listed both tools without credentials, so the material is reachable without a Tiger Data account. ### Who it is for Developers writing PostgreSQL or TimescaleDB code with an agent's help. ### Tool surface search\_docs and view\_skill are the whole surface, and the pairing is deliberate: retrieval for factual lookups, and a separate call for longer procedural guidance on TimescaleDB. Both are reads. Availability ## Where pg-aiguide is listed pg-aiguide is listed in the Claude connectors directory only. Tiger Data has no app under the same domain in the ChatGPT directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them. The MCP server behind a Claude connector is usually the same server a ChatGPT app would need, so the absence is a distribution decision rather than a technical one. Claude listing ## In the Claude connectors directory pg-aiguide publishes 2 tools to Claude, a deliberately narrow surface; only 5.3% of the 1,253 Claude-listed connectors expose fewer. The median Claude-listed connector filed under Developer Tools publishes 13, so this one sits 11 tools below its bucket's median, 83rd of 95. It falls in the 1-3 tools band, which holds 16.4% of the Claude directory. ### Measured against the live endpoint A direct call to the endpoint returned 2 tools, matching the 2 the listing publishes. Probed 2026-08-07. #### Tools the server actually returns - `search_docs` - `view_skill` pg-aiguide publishes a remote MCP endpoint. Claude connects to it over HTTP; there is nothing to install locally. Every connector in the Claude directory is remote, all 1,253 of them, so transport is not a differentiator there. Publisher Tiger Data Verification Verified partner (37.8% of the Claude directory) Filed under Developer Tools Endpoint `https://mcp.tigerdata.com/docs` Documentation [Publisher setup docs](https://github.com/timescale/pg-aiguide) Published tools 2 · 1-3 tools band Depth rank in Developer Tools 83 of 95 Snapshot August 2026 pg-aiguide carries partner verification in the Claude directory, which 474 of 1,253 listings do (37.8%). That is a review step past self-publishing, not an Anthropic-built server. In the publisher's words ## How Tiger Data describes it > Give your agent Postgres skills and documentation.
