LLMs rely on outdated or generic information about the libraries you use.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 basic Next.js project with app router. use context7
Create a script to delete the rows where the city is "" given PostgreSQL credentials. 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use context7No tab-switching, no hallucinated APIs that don't exist, no outdated code generations.
To install Context7 MCP Server for Claude Desktop automatically via Smithery:
npx -y @smithery/cli install @upstash/context7-mcp --client claude
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.
{ "mcpServers": { "context7": { "command": "npx", "args": ["-y", "@upstash/context7-mcp@latest"] } } }
Alternative: Use Bun
{ "mcpServers": { "context7": { "command": "bunx", "args": ["-y", "@upstash/context7-mcp@latest"] } } }
Alternative: Use Deno
{ "mcpServers": { "context7": { "command": "deno", "args": ["run", "--allow-net", "npm:@upstash/context7-mcp"] } } }
Add this to your Windsurf MCP config file. See Windsurf MCP docs for more info.
{ "mcpServers": { "context7": { "command": "npx", "args": ["-y", "@upstash/context7-mcp@latest"] } } }
Add this to your VS Code MCP config file. See VS Code MCP docs for more info.
{ "servers": { "Context7": { "type": "stdio", "command": "npx", "args": ["-y", "@upstash/context7-mcp@latest"] } } }
It can be installed via Zed Extensions or you can add this to your Zed settings.json. See Zed Context Server docs for more info.
{ "context_servers": { "Context7": { "command": { "path": "npx", "args": ["-y", "@upstash/context7-mcp@latest"] }, "settings": {} } } }
Run this command. See Claude Code MCP docs for more info.
claude mcp add context7 -- npx -y @upstash/context7-mcp@latest
Add this to your Claude Desktop claude_desktop_config.json file. See Claude Desktop MCP docs for more info.
{ "mcpServers": { "Context7": { "command": "npx", "args": ["-y", "@upstash/context7-mcp@latest"] } } }
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):
Click to see Dockerfile content
FROM node:18-alpine WORKDIR /app # Install the latest version globally RUN npm install -g @upstash/context7-mcp@latest # 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.
DEFAULT_MINIMUM_TOKENS: Set the minimum token count for documentation retrieval (default: 5000).Examples:
{ "mcpServers": { "context7": { "command": "npx", "args": ["-y", "@upstash/context7-mcp@latest"], "env": { "DEFAULT_MINIMUM_TOKENS": "10000" } } } }
resolve-library-id: Resolves a general library name into a Context7-compatible library ID.
libraryName (required)get-library-docs: Fetches documentation for a library using a Context7-compatible library ID.
context7CompatibleLibraryID (required)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 the configured DEFAULT_MINIMUM_TOKENS value are automatically increased to that value.Clone the project and install dependencies:
bun i
Build:
bun run build
{ "mcpServers": { "context7": { "command": "npx", "args": ["tsx", "/path/to/folder/context7-mcp/src/index.ts"] } } }
npx -y @modelcontextprotocol/inspector npx @upstash/context7-mcp@latest
If you see this error, try using bunx instead of npx.
{ "mcpServers": { "context7": { "command": "bunx", "args": ["-y", "@upstash/context7-mcp@latest"] } } }
This often resolves module resolution issues, especially in environments where npx does not properly install or resolve packages.
If you encounter an error like: Error: Cannot find module 'uriTemplate.js' try running with the --experimental-vm-modules flag:
{ "mcpServers": { "context7": { "command": "npx", "args": [ "-y", "--node-options=--experimental-vm-modules", "@upstash/context7-mcp@1.0.6" ] } } }
Try removing @latest from the package name.
Try using bunx as an alternative.
Try using deno as an alternative.
Make sure you are using Node v18 or higher to have native fetch support with npx.
