Augments▌

A next-generation framework documentation provider for Claude Code via Model Context Protocol (MCP). Returns types + prose + examples with context-aware formatting for any npm package — not just curated ones.

mcp-name: dev.augments/mcp

What's New in v5

Version 5.0 closes the gap with context7 by adding prose documentation, README fallback, concept search, and intent-aware formatting — while keeping the type-signature accuracy that made v4 unique.

What You Get Now

Query: "how to use zustand"
→ Intent: howto
→ Code examples first, then prose explanation, then brief signature

Query: "useEffect signature"
→ Intent: reference
→ Full signature, parameters, return type, related types, 1 example

Query: "ioredis set"
→ README fallback provides examples for uncurated packages

Quick Start

Option 1: Hosted MCP Server — project-local (Recommended)

# Add the hosted MCP server (available in current project only)
claude mcp add --transport http augments https://mcp.augments.dev/mcp

# Verify configuration
claude mcp list

Option 2: Hosted MCP Server — user-wide

# Add the hosted MCP server (available across all projects)
claude mcp add --transport http --scope user augments https://mcp.augments.dev/mcp

# Verify configuration
claude mcp list

Option 3: Using Cursor

{
  "mcpServers": {
    "augments": {
      "transport": "http",
      "url": "https://mcp.augments.dev/mcp"
    }
  }
}

Usage

# Get API context with prose + examples (recommended first tool to try)
@augments get_api_context query="useEffect cleanup" framework="react"

# How-to format — examples first
@augments get_api_context query="how to use zustand"

# Reference format — full signature first
@augments get_api_context query="zod object signature"

# Search for APIs by concept (synonym-aware)
@augments search_apis query="state management"

# Get version information and breaking changes
@augments get_version_info framework="react" fromVersion="18" toVersion="19"

Key Features

Concept Synonyms

"state management" matches useState, useReducer, createStore, atom, signal, ref, reactive, writable, store. Eight concept clusters cover state, form, fetch, animation, routing, auth, cache, and effect patterns.

README Fallback

For the 99%+ of npm packages without curated documentation sources, augments fetches README.md from the CDN and extracts concept-relevant code blocks and prose.

Auto-Discovery

When no curated doc source exists, augments parses the npm repository field, identifies the GitHub repo, and probes for docs/, documentation/, doc/, or README.md.

Intent-Aware Formatting

Coverage

Any npm Package

Every npm package is supported out of the box — no curation or configuration needed. Augments resolves documentation automatically through three layers:

1. TypeScript types — bundled ("types" in package.json) or DefinitelyTyped (@types/*)
2. Auto-discovered docs — parses the npm repository field, finds the GitHub repo, and probes docs/, documentation/, doc/ directories
3. README fallback — extracts concept-relevant code blocks and prose directly from README.md

This means augments works with the entire npm ecosystem (~2.5M packages), not just a curated subset.

Enhanced Results for Popular Frameworks

22 frameworks have curated doc sources for richer examples: React, Next.js, Vue, Prisma, Zod, Supabase, TanStack Query, tRPC, React Hook Form, Framer Motion, Express, Zustand, Jotai, Drizzle, SWR, Vitest, Playwright, Fastify, Hono, Solid, Svelte, Angular, Redux

Barrel Export Handling

Special sub-module resolution for: React Hook Form, TanStack Query, Zustand, Jotai, tRPC, Drizzle ORM, Next.js
