docsapi - Documentation API for LLMs

Need structured docs for an LLM? docsapi turns doc sites into clean Markdown.

Many documentation sites are JavaScript-heavy or fragmented across generators. docsapi fetches the page, extracts the content, and returns Markdown.

Apple Docs are supported as a docset type, alongside common generators like MkDocs, Sphinx, Docusaurus, TypeDoc, and more.

Apple Docs via /api (docset: apple)

Append the raw Apple docs URL to /api/:

Original: https://developer.apple.com/documentation/swift/array
AI-readable: https://docsapi.xo.vg/api/https://developer.apple.com/documentation/swift/array

Generic Docs API

Append any doc URL to /api/:

https://docsapi.xo.vg/api/https://docs.rs/serde/latest/serde/

Set Accept: application/json to receive { url, content }. Inputs ending in .html are normalized.

Examples

Local docs admin: /local-docs (password required).

MCP Usage

Connect your MCP client to https://docsapi.xo.vg/mcp.

GitHub Copilot for Xcode

Open GitHub Copilot for Xcode and go to Settings…
Select the MCP tab
Click Edit Config
Enter the following configuration:

{
  "servers": {      "docsapi": {
      "type": "http",
      "url": "https://docsapi.xo.vg/mcp"
    }  }
}

For more information, see the GitHub Copilot for Xcode README.

Cursor

Click the button below to automatically install the docsapi MCP server:

For more information, see the Cursor documentation.

VSCode

Create a .vscode/mcp.json file in your workspace and enter the following configuration:

{
  "servers": {      "docsapi": {
      "type": "http",
      "url": "https://docsapi.xo.vg/mcp"
    }  }
}

For more information, see the VSCode documentation.

Claude Desktop

Open Claude Desktop
Go to Settings → Connectors
Click "Add custom connector"
Set "Name" to docsapi
Set "Remote MCP server URL" to https://docsapi.xo.vg/mcp
Click "Add"

See the Claude Desktop documentation for more information.

Claude Code

Run the following command in your terminal:

claude mcp add --transport http docsapi https://docsapi.xo.vg/mcp

For more information, see the Claude Code MCP documentation.

Codex

Codex reads MCP servers from ~/.codex/config.toml. Add a table like:

[mcp_servers.docsapi]
url = "https://docsapi.xo.vg/mcp"

Other MCP Clients

docsapi's MCP server supports Streamable HTTP and Server-Sent Events (SSE) transport. If your client supports either of these, configure it to connect directly to https://docsapi.xo.vg/mcp.

Otherwise, you can run this command to proxy over stdio:

{
  "mcpServers": {
    "docsapi": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://docsapi.xo.vg/mcp"
      ]
    }  }
}

Troubleshooting

If you're experiencing connection timeouts or network issues with the MCP server, you may need to configure a proxy. This is particularly common in corporate environments or regions with restricted internet access.

Configure your MCP client to use a proxy by adding environment variables:

{
  "mcpServers": {
    "docsapi": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://docsapi.xo.vg/mcp"
      ],
      "env": {
        "HTTP_PROXY": "http://proxy.example.com:8080",
        "HTTPS_PROXY": "http://proxy.example.com:8080"
      }
    }  }
}

Replace proxy.example.com:8080 with your actual proxy server details. For authenticated proxies, use the format: http://username:[email protected]:8080
