listing.about

Grounded Docs builds a local documentation index for your AI coding assistant. It fetches docs from websites, GitHub, npm, PyPI, local folders and zip archives, then lets the assistant search the version of a library you actually use. It handles HTML, Markdown, PDF, Office files, Jupyter Notebooks and many source code languages.

It runs on your machine through npx (Node.js 22+) or Docker, with a web UI on port 6280 for adding documentation and an SSE endpoint for MCP clients. No sign-in is needed. An embeddings provider key such as OPENAI_API_KEY is optional and enables semantic search; Ollama, Gemini and Azure are also supported.

Claude Code

  1. Run this in a terminal, in your project folder:
claude mcp add --transport stdio grounded-docs -- npx @arabold/docs-mcp-server@latest
  1. Start Claude Code and type /mcp. grounded-docs should show as connected.

Add --scope user to make it available in every project.

Claude Desktop

  1. Open Settings → Developer → Edit Config. It opens claude_desktop_config.json. Add:
claude_desktop_config.json
{
  "mcpServers": {
    "grounded-docs": {
      "command": "npx",
      "args": [
        "@arabold/docs-mcp-server@latest"
      ]
    }
  }
}
  1. Save the file and restart Claude Desktop.

Needs Node.js on your computer. The file lives in ~/Library/Application Support/Claude/ on macOS and %APPDATA%\Claude\ on Windows.

Cursor

Add to Cursor a11y.new_tab

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

mcp.json
{
  "mcpServers": {
    "grounded-docs": {
      "command": "npx",
      "args": [
        "@arabold/docs-mcp-server@latest"
      ]
    }
  }
}

Needs Node.js on your computer.

VS Code

Install in VS Code a11y.new_tab

Or from a terminal:

code --add-mcp '{"name":"grounded-docs","type":"stdio","command":"npx","args":["@arabold/docs-mcp-server@latest"]}'

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

.vscode/mcp.json
{
  "servers": {
    "grounded-docs": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "@arabold/docs-mcp-server@latest"
      ]
    }
  }
}

Needs Node.js on your computer.

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": {
    "grounded-docs": {
      "command": "npx",
      "args": [
        "@arabold/docs-mcp-server@latest"
      ]
    }
  }
}
  1. Refresh the MCP server list in Cascade.

Devin Desktop is the new name for Windsurf.

Codex

codex mcp add grounded-docs -- npx @arabold/docs-mcp-server@latest

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

config.toml
[mcp_servers.grounded-docs]
command = "npx"
args = ["@arabold/docs-mcp-server@latest"]

Needs Node.js on your computer.

Gemini CLI

gemini mcp add grounded-docs npx @arabold/docs-mcp-server@latest

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

Any client

Most clients that start local servers accept this shape:

{
  "mcpServers": {
    "grounded-docs": {
      "command": "npx",
      "args": [
        "@arabold/docs-mcp-server@latest"
      ]
    }
  }
}

Zed puts servers under context_servers in its settings, with the same command, args and env fields.

Needs Node.js on your computer.

listing.faq

Can I paste mcp.tc/i/grounded-docs into my MCP client?

No. Grounded Docs runs on your own computer, started by your client, so it has no web address to connect to. The quick link is the page to share; the install command is npx @arabold/docs-mcp-server@latest.

Does Grounded Docs need an API key?

No. It doesn't declare any keys or environment variables. It runs with your user account's permissions, so check what its tools can reach.

Is Grounded Docs a remote or a local server?

Local. Your client starts it as a process on your computer with npx @arabold/docs-mcp-server@latest, which needs Node.js.

What can Grounded Docs do?

You can scrape documentation from websites, GitHub, npm, PyPI and local files, search indexed docs for a specific library version and fetch a single page as Markdown.

Which clients can use it?

Any client that starts local servers: Claude Code, Claude Desktop, Cursor, VS Code, Devin Desktop, Codex, Gemini CLI, Zed and others. claude.ai and ChatGPT only connect to remote servers.

Who wrote this page?

mcp.tc's robot read Grounded Docs's public metadata (its package and repository 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.
