doc-fetcher

Claude Code plugin that fetches documentation and converts it to markdown. Integrates with Dash for instant access to 200+ docsets, or fetches any URL directly.

Features

Dash integration - Search your installed Dash docsets by name (react, typescript, python, etc.)
Direct URL fetch - Grab docs from any URL and convert to clean markdown
Section extraction - Pull just the section you need (e.g., "Parameters", "Usage")
Token limiting - Control response size for quick lookups

Installation

As a Claude Code plugin (recommended)

# Add the marketplace
/plugin marketplace add Robdel12/doc-fetcher-mcp

# Install the plugin
/plugin install doc-fetcher@doc-fetcher

Or via CLI:

claude plugin marketplace add Robdel12/doc-fetcher-mcp
claude plugin install doc-fetcher@doc-fetcher

Requirements

Claude Code 1.0.33+
Node.js 18+
Dash (optional, for docset search)
- Enable API Server: Dash > Settings > Integration > Enable API Server

Usage

Once installed, Claude can fetch documentation automatically. Just ask:

"Look up the useEffect hook in React docs"

"Get the Parameters section from useState documentation"

"Fetch https://docs.anthropic.com/en/docs/claude-code/overview"

Tool parameters

| Parameter | Type | Description | |-----------|------|-------------| | query | string | Search query for Dash docsets | | docset | string | Docset to search - platform name (react, typescript, node) or Dash identifier | | url | string | Direct URL to fetch (bypasses Dash) | | section | string | Extract only a specific section by heading | | maxTokens | number | Max tokens to return (default: 20000) |

Examples

// Search React docs
{ "query": "useEffect", "docset": "react" }

// Search all docsets
{ "query": "async await" }

// Get a specific section
{ "query": "useEffect", "docset": "react", "section": "Parameters" }

// Fetch any URL
{ "url": "https://docs.anthropic.com/en/docs/claude-code/overview" }

// Limit response size
{ "query": "useState", "docset": "react", "maxTokens": 2000 }

How it works

Dash search: Queries the local Dash API to find matching documentation
Fetch: Retrieves the HTML content from Dash's local server or any URL
Convert: Uses Readability + Turndown to extract clean markdown
Extract: Optionally pulls just the section you need
Return: Markdown content with title, truncation status, and alternative results
