Context7 MCP - Up-to-date Code Docs For Any Prompt

-purple>)

❌ Without Context7

LLMs rely on outdated or generic information about the libraries you use. You get:

• ❌ Code examples are outdated and based on year-old training data
• ❌ Hallucinated APIs that don't even exist
• ❌ Generic answers for old package versions

✅ With Context7

Context7 MCP pulls up-to-date, version-specific documentation and code examples straight from the source — and places them directly into your prompt.

Add use context7 to your prompt in Cursor:

Create a Next.js middleware that checks for a valid JWT in cookies and redirects unauthenticated users to `/login`. use context7

Configure a Cloudflare Worker script to cache JSON API responses for five minutes. use context7

Context7 fetches up-to-date code examples and documentation right into your LLM's context.

• 1️⃣ Write your prompt naturally
• 2️⃣ Tell the LLM to use context7
• 3️⃣ Get working code answers

No tab-switching, no hallucinated APIs that don't exist, no outdated code generations.

🛠️ Installation

Requirements

• Node.js >= v18.0.0
• Cursor, Claude Code, VSCode, Windsurf or another MCP Client
• Context7 API Key (Optional for higher rate limits) (Get yours by creating an account at context7.com/dashboard)

[!WARNING] SSE Protocol Deprecation Notice

The Server-Sent Events (SSE) transport protocol is deprecated and its endpoint will be removed in upcoming releases. Please use HTTP or stdio transport methods instead.

<summary>Install in Cursor</summary> Go to: Settings -> Cursor Settings -> MCP -> Add new global MCP server Pasting the following configuration into your Cursor ~/.cursor/mcp.json file is the recommended approach. You may also install in a specific project by creating .cursor/mcp.json in your project folder. See Cursor MCP docs for more info. > Since Cursor 1.0, you can click the install button below for instant one-click installation. #### Cursor Remote Server Connection json { "mcpServers": { "context7": { "url": "https://mcp.context7.com/mcp", "headers": { "CONTEXT7_API_KEY": "YOUR_API_KEY" } } } } #### Cursor Local Server Connection json { "mcpServers": { "context7": { "command": "npx", "args": ["-y", "@upstash/context7-mcp", "--api-key", "YOUR_API_KEY"] } } }

<summary>Install in VS Code</summary> Add this to your VS Code MCP config file. See VS Code MCP docs for more info. #### VS Code Remote Server Connection json "mcp": { "servers": { "context7": { "type": "http", "url": "https://mcp.context7.com/mcp", "headers": { "CONTEXT7_API_KEY": "YOUR_API_KEY" } } } } #### VS Code Local Server Connection json "mcp": { "servers": { "context7": { "type": "stdio", "command": "npx", "args": ["-y", "@upstash/context7-mcp", "--api-key", "YOUR_API_KEY"] } } }

   docker build -t context7-mcp .

<summary>Install in LM Studio</summary> See LM Studio MCP Support for more information. #### One-click install: #### Manual set-up: 1. Navigate to Program (right side) > Install > Edit mcp.json. 2. Paste the configuration given below: json { "mcpServers": { "Context7": { "command": "npx", "args": ["-y", "@upstash/context7-mcp", "--api-key", "YOUR_API_KEY"] } } } 3. Click Save to apply the changes. 4. Toggle the MCP server on/off from the right hand side, under Program, or by clicking the plug icon at the bottom of the chat box.

🔨 Available Tools

Context7 MCP provides the following tools that LLMs can use:

• resolve-library-id: Resolves a general library name into a Context7-compatible library ID.

  • libraryName (required): The name of the library to search for

• get-library-docs: Fetches documentation for a library using a Context7-compatible library ID.

  • context7CompatibleLibraryID (required): Exact Context7-compatible library ID (e.g., /mongodb/docs, /vercel/next.js)
  • topic (optional): Focus the docs on a specific topic (e.g., "routing", "hooks")
  • tokens (optional, default 5000): Max number of tokens to return. Values less than 1000 are automatically increased to 1000.

🛟 Tips

Add a Rule

If you don’t want to add use context7 to every prompt, you can define a simple rule in your .windsurfrules file in Windsurf or from Cursor Settings > Rules section in Cursor (or the equivalent in your MCP client) to auto-invoke Context7 on any code question:

[[calls]]
match = "when the user requests code examples, setup or configuration steps, or library/API documentation"
tool  = "context7"

From then on you’ll get Context7’s docs in any related conversation without typing anything extra. You can add your use cases to the match part.

Use Library Id

If you already know exactly which library you want to use, add its Context7 ID to your prompt. That way, Context7 MCP server can skip the library-matching step and directly continue with retrieving docs.

implement basic authentication with supabase. use library /supabase/supabase for api and docs

The slash syntax tells the MCP tool exactly which library to load docs for.

HTTPS Proxy

If you are behind an HTTP proxy, Context7 uses the standard https_proxy / HTTPS_PROXY environment variables.

💻 Development

Clone the project and install dependencies:

bun i

Build:

bun run build

Run the server:

bun run dist/index.js

CLI Arguments

context7-mcp accepts the following CLI flags:

• --transport <stdio|http> – Transport to use (stdio by default). Note that HTTP transport automatically provides both HTTP and SSE endpoints.
• --port <number> – Port to listen on when using http transport (default 3000).
• --api-key <key> – API key for authentication. You can get your API key by creating an account at context7.com/dashboard.

Example with http transport and port 8080:

bun run dist/index.js --transport http --port 8080

Another example with stdio transport:

bun run dist/index.js --transport stdio --api-key YOUR_API_KEY
