Context7 MCP - Up-to-date Code Docs For Any Prompt
<img alt="Install in VS Code (npx)" src="https://img.shields.io/badge/VS_Code-VS_Code?style=flat-square&label=Install%20Context7%20MCP&color=0098FF">
❌ 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LLMs rely on outdated or generic information about the libraries you use.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- ❌ Code examples are outdated and based on year-old training data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 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No tab-switching, no hallucinated APIs that don't exist, no outdated code generations.
📚 Adding Projects
Check out our project addition guide to learn how to add (or update) your favorite libraries to Context7.
🛠️ Installation

mcpServersobject in yoursettings.jsonfile:
{
"mcpServers": {
"context7": {
"command": "npx",
"args": ["-y", "@upstash/context7-mcp"]

}
}
You can easily install Context7 through the Cline MCP Server Marketplace by following these instructions:
- Open Cline.
- Click the hamburger menu icon (☰) to enter the MCP Servers section.
- Use the search bar within the Marketplace tab to find Context7.
- Click the Install button.
Open the "Settings" page of the app, navigate to "Plugins," and enter the following JSON:
{
"mcpServers": {
"context7": {
"command": "npx",
"args": ["-y", "@upstash/context7-mcp"]
}
}
}
Once saved, enter in the chat get-library-docs followed by your Context7 documentation ID (e.g., get-library-docs /nuxt/ui). More information is available on BoltAI's Documentation site. For BoltAI on iOS, see this guide.
If you prefer to run the MCP server in a Docker container:
-
Build the Docker Image:
First, create a
<details> <summary>Click to see Dockerfile content</summary>Dockerfilein the project root (or anywhere you prefer):</details>DockerfileFROM 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 theDockerfile:bashdocker 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:
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.,
mcpServersvsservers). Also, ensure the image name inargsmatches the tag used during thedocker buildcommand.
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.
{
"mcpServers": {
"github.com/upstash/context7-mcp": {
"command": "cmd",
"args": ["/c", "npx", "-y", "@upstash/context7-mcp@latest"],

🔨 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 10000): Max number of tokens to return. Values less than the default value of 10000 are automatically increased to 10000.
🛟 Tips
Add a Rule
If you don’t want to add
use context7to every prompt, you can define a simple rule in your.windsurfrulesfile in Windsurf or fromCursor Settings > Rulessection in Cursor (or the equivalent in your MCP client) to auto-invoke Context7 on any code question:toml[[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.
txtimplement basic authentication with supabase. use library /supabase/supabase for api and docsThe slash syntax tells the MCP tool exactly which library to load docs for.
💻 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|sse>– Transport to use (stdioby default).--port <number>– Port to listen on when usinghttporssetransport (default3000).
Example with http transport and port 8080:
bun run dist/index.js --transport http --port 8080
{
"mcpServers": {
"context7": {
"command": "npx",
"args": ["tsx", "/path/to/folder/context7-mcp/src/index.ts"]
}
}
}
npx -y @modelcontextprotocol/inspector npx @upstash/context7-mcp
🚨 Troubleshooting
<details> <summary><b>Module Not Found Errors</b></summary>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/context7-mcp@1.0.6"]
}
}
}
Use the --experimental-fetch flag to bypass TLS-related problems:
{
"mcpServers": {
"context7": {
"command": "npx",
"args": ["-y", "--node-options=--experimental-fetch", "@upstash/context7-mcp"]
}
}
}
- Try adding
@latestto the package name - Use
bunxas an alternative tonpx - Consider using
denoas another alternative - Ensure you're using Node.js v18 or higher for native fetch support
