Mintlify Index

Warning

Mintlify Index has been discontinued and this repo is no longer maintained. The hosted MCP server and the mint index command have been shut down.

Real-time documentation retrieval for coding agents.

Mintlify Index answers implementation questions (syntax, configuration, migration, setup) with compact, cited context assembled from primary-source developer documentation and live web search. It ships as a hosted MCP server exposing a single context tool.

Quickstart

npx mint index

The interactive installer detects your coding agents and adds the hosted MCP server (https://index.mintlify.com/mcp) plus a usage rule so the agent reaches for it automatically. Supported clients:

• Claude Code
• Cursor
• VS Code (Copilot)
• Codex
• OpenCode
• Windsurf
• Zed

Non-interactive setup:

npx mint index --claude --cursor --yes     # specific clients, skip prompts
npx mint index --project                   # write project-level config instead of global

Any other MCP client can be pointed at the server manually:

{
  "mcpServers": {
    "mintlify-index": {
      "type": "http",
      "url": "https://index.mintlify.com/mcp"
    }
  }
}

The context tool takes a query (plus optional product, includeDomains, excludeDomains, and a tokenBudget up to 6000) and returns a cited answer in one call.

About this repo

This is a source release of the hosted service. It is not runnable standalone: docs ingestion, the Chroma corpus, auth, and infrastructure live in the Mintlify platform and are represented here by small interfaces in src/internal/. src/server.ts shows how the pieces wire together in production.
