listing.about

pg-aiguide gives coding assistants version-aware documentation search across PostgreSQL, Tiger Cloud (TimescaleDB) and PostGIS. Search combines keyword (BM25) and semantic vector ranking, and the weighting is adjustable. It also serves curated skills for table design, hypertables, pgvector, hybrid text search, schema exploration and safe migrations.

It runs as a hosted streamable-http endpoint at https://mcp.tigerdata.com/docs. No sign-in or API key is needed. The same project is also published as an npm package and container image, and as a Claude Code plugin.

listing.can

  • Search PostgreSQL, TimescaleDB and PostGIS documentation
  • Switch between keyword-only, semantic-only or blended search
  • Load Postgres table design best-practice skills

  • Plan and test PostgreSQL schema migrations
  • Set up pgvector and hybrid BM25 plus vector search

listing.tools 2

  • search_docslisting.hint.ro

    Hybrid keyword and semantic search over Tiger Cloud, PostgreSQL and PostGIS documentation.

Claude Code

  1. Run this in a terminal, in your project folder:
claude mcp add --transport http pg-aiguide https://mcp.tigerdata.com/docs
  1. Start Claude Code and type /mcp. pg-aiguide should show as connected.

Add --scope user to make it available in every project, not just this one.

Claude Desktop

  1. Open Settings → Connectors and click Add custom connector.
  2. Name it pg-aiguide and paste this URL:
https://mcp.tigerdata.com/docs
  1. Click Add. Its tools appear in the chat's tools menu.

Claude Desktop's JSON config file only starts local servers. Remote servers go through Connectors, and connectors you add on claude.ai show up here too.

claude.ai

  1. Open the connector form on claude.ai. This button fills in the name and URL for you:
  1. Check that the URL reads https://mcp.tigerdata.com/docs and click Add.
  2. Turn it on in a chat from the tools menu.

Free plans allow one custom connector. On Team and Enterprise plans an owner adds it under Organization settings → Connectors.

ChatGPT

  1. On chatgpt.com, open Settings → Security and login and turn on Developer mode.
  2. Go to chatgpt.com/plugins and click + to create an app for a remote MCP server.
  3. Paste https://mcp.tigerdata.com/docs as the server URL and choose No authentication.

Developer mode is available on the web for Plus, Pro, Business, Enterprise and Education accounts.

Cursor

Or add it by hand to ~/.cursor/mcp.json (all projects) or .cursor/mcp.json (this project):

mcp.json
{
  "mcpServers": {
    "pg-aiguide": {
      "url": "https://mcp.tigerdata.com/docs"
    }
  }
}

VS Code

Or from a terminal:

code --add-mcp '{"name":"pg-aiguide","type":"http","url":"https://mcp.tigerdata.com/docs"}'

Or commit it to the repo in .vscode/mcp.json:

.vscode/mcp.json
{
  "servers": {
    "pg-aiguide": {
      "type": "http",
      "url": "https://mcp.tigerdata.com/docs"
    }
  }
}

Devin Desktop

  1. Add it to ~/.config/devin/mcp_config.json (macOS and Linux) or %APPDATA%\devin\mcp_config.json (Windows):
mcp_config.json
{
  "mcpServers": {
    "pg-aiguide": {
      "serverUrl": "https://mcp.tigerdata.com/docs"
    }
  }
}
  1. Refresh the MCP server list in Cascade.

Devin Desktop is the new name for Windsurf. It reads serverUrl (or url) for remote servers.

Codex

codex mcp add pg-aiguide --url https://mcp.tigerdata.com/docs

Or edit ~/.codex/config.toml directly:

config.toml
[mcp_servers.pg-aiguide]
url = "https://mcp.tigerdata.com/docs"

Gemini CLI

gemini mcp add --transport http pg-aiguide https://mcp.tigerdata.com/docs

This adds it to the current project. Add -s user to use it everywhere.

Any client

Most clients accept this shape. Some name the URL field differently: serverUrl in Devin Desktop, httpUrl in Gemini CLI's settings file.

{
  "mcpServers": {
    "pg-aiguide": {
      "type": "http",
      "url": "https://mcp.tigerdata.com/docs"
    }
  }
}

Zed puts servers under context_servers in its settings. Cline needs "type": "streamableHttp", or it assumes SSE.

Client only starts local servers? Bridge it with npx -y mcp-remote https://mcp.tigerdata.com/docs.

listing.faq

Can I paste mcp.tc/i/pg-aiguide into my MCP client?

No. mcp.tc links are pages, not server addresses. Connect with https://mcp.tigerdata.com/docs, so your client talks to pg-aiguide directly. The quick link is for sharing: it opens this page, with setup steps for every client.

Does pg-aiguide need an API key or a sign-in?

No. pg-aiguide doesn't ask for an account or key.

Is pg-aiguide a remote or a local server?

Remote. Tiger Data (Timescale) hosts it at https://mcp.tigerdata.com/docs, and it speaks Streamable HTTP. There's nothing to install.

What can pg-aiguide do?

It has 2 tools: search_docs and view_skill. You can search PostgreSQL, TimescaleDB and PostGIS documentation, switch between keyword-only, semantic-only or blended search and load Postgres table design best-practice skills.

Which clients can use it?

Any client that supports remote MCP servers: Claude Code, Claude Desktop, claude.ai, ChatGPT in developer mode, Cursor, VS Code, Devin Desktop, Codex, Gemini CLI, Zed and others. The setup steps cover each one.

Who wrote this page?

mcp.tc's robot read pg-aiguide's own metadata (its MCP handshake, tool list and public pages), and an AI model drafted the text from it. A person reviews anything the checks can't confirm. The text can still be wrong, so if you spot a mistake, use Report this listing on this page.
