LLMs rely on outdated or generic information about the libraries you use. You get:
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.
use context7No tab-switching, no hallucinated APIs that don't exist, no outdated code generation.
[!NOTE] This repository hosts the source code of Context7 MCP server. The supporting components — API backend, parsing engine, and crawling engine — are private and not part of this release.
Check out our project addition guide to learn how to add (or update) your favorite libraries to Context7.

[mcp_servers.context7] url = "https://mcp.context7.com/mcp" http_headers = { "CONTEXT7_API_KEY" = "YOUR_API_KEY" }
Optional troubleshooting — only if you see startup "request timed out" or "not found program". Most users can ignore this.
- First try: increase
 startup_timeout_msto40_000and retry.- Windows quick fix (absolute
 npxpath + explicit env):[mcp_servers.context7] command = "C:\\Users\\yourname\\AppData\\Roaming\\npm\\npx.cmd" args = [ "-y", "@upstash/context7-mcp", "--api-key", "YOUR_API_KEY" ] env = { SystemRoot="C:\\Windows", APPDATA="C:\\Users\\yourname\\AppData\\Roaming" } startup_timeout_ms = 40_000
- macOS quick fix (use Node + installed package entry point):
 [mcp_servers.context7] command = "/Users/yourname/.nvm/versions/node/v22.14.0/bin/node" args = ["/Users/yourname/.nvm/versions/node/v22.14.0/lib/node_modules/@upstash/context7-mcp/dist/index.js", "--transport", "stdio", "--api-key", "YOUR_API_KEY" ]Notes: Replace
yournamewith your OS username. Explicitly settingAPPDATAandSystemRootis essential because these are required bynpxon Windows but not set by certain versions of OpenAI Codex mcp clients by default.

If you prefer to run the MCP server in a Docker container:
Build the Docker Image:
First, create a Dockerfile in the project root (or anywhere you prefer):
FROM node:18-alpine WORKDIR /app # Install the latest version globally RUN npm install -g @upstash/context7-mcp # Expose default port if needed (optional, depends on MCP client interaction) # EXPOSE 3000 # Default command to run the server CMD ["context7-mcp"]
Then, build the image using a tag (e.g., context7-mcp). Make sure Docker Desktop (or the Docker daemon) is running. Run the following command in the same directory where you saved the Dockerfile:
docker build -t context7-mcp .
Configure Your MCP Client:
Update your MCP client's configuration to use the Docker command.
Example for a cline_mcp_settings.json:
{ "mcpServers": { "Сontext7": { "autoApprove": [], "disabled": false, "timeout": 60, "command": "docker", "args": ["run", "-i", "--rm", "context7-mcp"], "transportType": "stdio" } } }
Note: This is an example configuration. Please refer to the specific examples for your MCP client (like Cursor, VS Code, etc.) earlier in this README to adapt the structure (e.g., mcpServers vs servers). Also, ensure the image name in args matches the tag used during the docker build command.
Install the context7.mcpb file under the mcpb folder and add it to your client. For more information, please check out MCP bundles docs.
The configuration on Windows is slightly different compared to Linux or macOS (Cline is used in the example). The same principle applies to other editors; refer to the configuration of command and args.

Save.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 forget-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.If you don’t want to add use context7 to every prompt, you can define a simple rule in your MCP client's rule section:
.windsurfrules fileCursor Settings > Rules sectionCLAUDE.md fileOr the equivalent in your MCP client to auto-invoke Context7 on any code question.
Always use context7 when I need code generation, setup or configuration steps, or library/API documentation. This means you should automatically use the Context7 MCP tools to resolve library id and get library docs without me having to explicitly ask.
From then on, you’ll get Context7’s docs in any related conversation without typing anything extra. You can alter the rule to match your use cases.
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.
If you are behind an HTTP proxy, Context7 uses the standard https_proxy / HTTPS_PROXY environment variables.
Clone the project and install dependencies:
bun i
Build:
bun run build
Run the server:
bun run dist/index.js
context7-mcp accepts the following CLI flags:
--transport <stdio|http> – Transport to use (stdio by default). Use http for remote HTTP server or stdio for local integration.--port <number> – Port to listen on when using http transport (default 3000).--api-key <key> – API key for authentication (or set CONTEXT7_API_KEY env var). 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
You can use the CONTEXT7_API_KEY environment variable instead of passing the --api-key flag. This is useful for:
.env filesNote: The --api-key CLI flag takes precedence over the environment variable when both are provided.
Example with .env file:
# .env CONTEXT7_API_KEY=your_api_key_here
Example MCP configuration using environment variable:
{ "mcpServers": { "context7": { "command": "npx", "args": ["-y", "@upstash/context7-mcp"], "env": { "CONTEXT7_API_KEY": "YOUR_API_KEY" } } } }
{ "mcpServers": { "context7": { "command": "npx", "args": ["tsx", "/path/to/folder/context7/src/index.ts", "--api-key", "YOUR_API_KEY"] } } }
npx -y @modelcontextprotocol/inspector npx @upstash/context7-mcp
If you encounter ERR_MODULE_NOT_FOUND, try using bunx instead of npx:
{ "mcpServers": { "context7": { "command": "bunx", "args": ["-y", "@upstash/context7-mcp"] } } }
This often resolves module resolution issues in environments where npx doesn't properly install or resolve packages.
For errors like Error: Cannot find module 'uriTemplate.js', try the --experimental-vm-modules flag:
{ "mcpServers": { "context7": { "command": "npx", "args": ["-y", "--node-options=--experimental-vm-modules", "@upstash/[email protected]"] } } }
Use the --experimental-fetch flag to bypass TLS-related problems:
{ "mcpServers": { "context7": { "command": "npx", "args": ["-y", "--node-options=--experimental-fetch", "@upstash/context7-mcp"] } } }
