npm install context7-mcp-serverContext7 MCP - Up-to-date Code Docs For Any Prompt
 
           
❌ 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LLMs rely on outdated or generic information about the libraries you use.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- ❌ Code examples are outdated and based on year-old training data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:
``txt`
Create a basic Next.js project with app router. use context7
`txt`
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.
- 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No tab-switching, no hallucinated APIs that don't exist, no outdated code generations.

Using Docker
If you prefer to run the MCP server in a Docker container:
1. Build the Docker Image:
First, create a Dockerfile in the project root (or anywhere you prefer):
Click to see Dockerfile content
`Dockerfile
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:
`bash`
docker build -t context7-mcp .
2. 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., mcpServers vs servers). Also, ensure the image name in args matches the tag used during the docker build command._
Install in Windows
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.
`json`
{
"mcpServers": {
"github.com/upstash/context7-mcp": {
"command": "cmd",
"args": ["/c", "npx", "-y", "@upstash/context7-mcp@latest"],
"disabled": false,
"autoApprove": []
}
}
}
Install in Augment Code
To configure Context7 MCP in Augment Code, follow these steps:
1. Press Cmd/Ctrl Shift P or go to the hamburger menu in the Augment panel
2. Select Edit Settings
3. Under Advanced, click Edit in settings.json
4. Add the server configuration to the mcpServers array in the augment.advanced object
`json`
"augment.advanced": {
"mcpServers": [
{
"name": "context7",
"command": "npx",
"args": ["-y", "@upstash/context7-mcp"]
}
]
}
Once the MCP server is added, restart your editor. If you receive any errors, check the syntax to make sure closing brackets or commas are not missing.
Install in Roo Code
Add this to your Roo Code MCP configuration file. See Roo Code MCP docs for more info.
#### Roo Code Remote Server Connection
`json`
{
"mcpServers": {
"context7": {
"type": "streamable-http",
"url": "https://mcp.context7.com/mcp"
}
}
}
#### Roo Code Local Server Connection
`json`
{
"mcpServers": {
"context7": {
"command": "npx",
"args": ["-y", "@upstash/context7-mcp"]
}
}
}
Install in Zencoder
To configure Context7 MCP in Zencoder, follow these steps:
1. Go to the Zencoder menu (...)
2. From the dropdown menu, select Agent tools
3. Click on the Add custom MCP
4. Add the name and server configuration from below, and make sure to hit the Install button
`json`
{
"command": "npx",
"args": [
"-y",
"@upstash/context7-mcp@latest"
]
}
Once the MCP server is added, you can easily continue using it.
Install in Amazon Q Developer CLI
Add this to your Amazon Q Developer CLI configuration file. See Amazon Q Developer CLI docs for more details.
`json`
{
"mcpServers": {
"context7": {
"command": "npx",
"args": ["-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.
💻 Development
Clone the project and install dependencies:
`bash`
bun i
Build:
`bash`
bun run build
Run the server:
`bash`
bun run dist/index.js
$3
context7-mcp accepts the following CLI flags:
- --transport – Transport to use (stdio by default).--port
- – Port to listen on when using http or sse transport (default 3000).
Example with http transport and port 8080:
`bash`
bun run dist/index.js --transport http --port 8080
Local Configuration Example
`json`
{
"mcpServers": {
"context7": {
"command": "npx",
"args": ["tsx", "/path/to/folder/context7-mcp/src/index.ts"]
}
}
}
Testing with MCP Inspector
`bash`
npx -y @modelcontextprotocol/inspector npx @upstash/context7-mcp
🚨 Troubleshooting
Module Not Found Errors
If you encounter ERR_MODULE_NOT_FOUND, try using bunx instead of npx:
`json`
{
"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.
ESM Resolution Issues
For errors like Error: Cannot find module 'uriTemplate.js', try the --experimental-vm-modules flag:
`json`
{
"mcpServers": {
"context7": {
"command": "npx",
"args": ["-y", "--node-options=--experimental-vm-modules", "@upstash/context7-mcp@1.0.6"]
}
}
}
TLS/Certificate Issues
Use the --experimental-fetch flag to bypass TLS-related problems:
`json`
{
"mcpServers": {
"context7": {
"command": "npx",
"args": ["-y", "--node-options=--experimental-fetch", "@upstash/context7-mcp"]
}
}
}
General MCP Client Errors
1. Try adding @latest to the package namebunx
2. Use as an alternative to npx
3. Consider using
4. Ensure you're using Node.js v18 or higher for native fetch support
