Install in BoltAI

Open the "Settings" page of the app, navigate to "Plugins," and enter the following JSON: ```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](https://docs.boltai.com/docs/plugins/mcp-servers). For BoltAI on iOS, [see this guide](https://docs.boltai.com/docs/boltai-mobile/mcp-servers).

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](https://docs.roocode.com/features/mcp/using-mcp-in-roo) 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](https://docs.aws.amazon.com/amazonq/latest/qdeveloper-ug/command-line-mcp-configuration.html) 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 ``` ### CLI Arguments `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 name 2. Use `bunx` as an alternative to `npx` 3. Consider using `deno` as another alternative 4. Ensure you're using Node.js v18 or higher for native fetch support
