# Search1API MCP Server



[中文文档](./README_zh.md)



A Model Context Protocol (MCP) server that provides search and crawl functionality using Search1API.



## Prerequisites



- Node.js >= 18.0.0

- A valid Search1API API key (See **Setup Guide** below on how to obtain and configure)



## Installation (Standalone / General)



1.  **Clone the repository:**

    ```bash

    git clone https://github.com/fatwang2/search1api-mcp.git

    cd search1api-mcp

    ```



2.  **Configure API Key:** Before building, you need to provide your Search1API key. See the **Setup Guide** section below for different methods (e.g., using a `.env` file or environment variables).



3.  **Install dependencies and build:**

    ```bash

    npm install

    npm run build

    ```

    *Note: If using the project's `.env` file method for the API key, ensure it exists before this step.*



## Usage (Standalone / General)



Ensure your API key is configured (see **Setup Guide**).



Start the server:

```bash

npm start

```



The server will then be ready to accept connections from MCP clients.



## Setup Guide



### 1. Get Search1API Key



1.  Register at [Search1API](https://www.search1api.com/?utm_source=mcp)

2.  Get your API key from your dashboard.



### 2. Configure API Key



You need to make your API key available to the server. Choose **one** of the following methods:



**Method A: Project `.env` File (Recommended for Standalone or LibreChat)**



This method is required if integrating with the current version of LibreChat (see specific section below).



1.  In the `search1api-mcp` project root directory, create a file named `.env`:

    ```bash

    # In the search1api-mcp directory

    echo "SEARCH1API_KEY=your_api_key_here" > .env

    ```

2.  Replace `your_api_key_here` with your actual key.

3.  Make sure this file exists **before** running `npm install && npm run build`.



**Method B: Environment Variable (Standalone Only)**



Set the `SEARCH1API_KEY` environment variable before starting the server.



```bash

export SEARCH1API_KEY="your_api_key_here"

npm start

```



**Method C: MCP Client Configuration (Advanced)**



Some MCP clients allow specifying environment variables directly in their configuration. This is useful for clients like Cursor, VS Code extensions, etc.



```json

{

  "mcpServers": {

    "search1api": {

      "command": "npx",

      "args": [

        "-y",

        "search1api-mcp"

      ],

      "env": {

        "SEARCH1API_KEY": "YOUR_SEARCH1API_KEY"

      }

    }

  }

}

```



**Note for LibreChat Users:** Due to current limitations in LibreChat, Method A (Project `.env` File) is the **required** method. See the dedicated integration section below for full instructions.



## Integration with LibreChat (Docker)



This section details the required steps for integrating with LibreChat via Docker.



**Overview:**



1.  Clone this server's repository into a location accessible by your LibreChat `docker-compose.yml`.

2.  Configure the required API key using the **Project `.env` File method** within this server's directory.

3.  Build this server.

4.  Tell LibreChat how to run this server by editing `librechat.yaml`.

5.  Make sure the built server code is available inside the LibreChat container via a Docker volume bind.

6.  Restart LibreChat.



**Step-by-Step:**



1.  **Clone the Repository:**

    Navigate to the directory on your host machine where you manage external services for LibreChat (this is often alongside your `docker-compose.yml`). A common location is a dedicated `mcp-server` directory.

    ```bash

    # Example: Navigate to where docker-compose.yml lives, then into mcp-server

    cd /path/to/your/librechat/setup/mcp-server

    git clone https://github.com/fatwang2/search1api-mcp.git

    ```



2.  **Navigate into the Server Directory:**

    ```bash

    cd search1api-mcp

    ```



3.  **Configure API Key (Project `.env` File Method - Required for LibreChat):**

    ```bash

    # Create the .env file

    echo "SEARCH1API_KEY=your_api_key_here" > .env

    # IMPORTANT: Replace 'your_api_key_here' with your actual Search1API key

    ```



4.  **Install Dependencies and Build:**

    This step compiles the server code into the `build` directory.

    ```bash

    npm install

    npm run build

    ```



5.  **Configure `librechat.yaml`:**

    Edit your main `librechat.yaml` file to tell LibreChat how to execute this MCP server. Add an entry under `mcp_servers`:

    ```yaml

    # In your main librechat.yaml

    mcp_servers:

      # You can add other MCP servers here too

      search1api:

        # Optional: Display name for the server in LibreChat UI

        # name: Search1API Tools



        # Command tells LibreChat to use 'node'

        command: node



        # Args specify the script for 'node' to run *inside the container*

        args:

          - /app/mcp-server/search1api-mcp/build/index.js

    ```

    *   The `args` path (`/app/...`) is the location *inside* the LibreChat API container where the built server will be accessed (thanks to the volume bind in the next step).



6.  **Configure Docker Volume Bind:**

    Edit your `docker-compose.yml` (or more likely, your `docker-compose.override.yml`) to map the `search1api-mcp` directory from your host machine into the LibreChat API container. Find the `volumes:` section for the `api:` service:

    ```yaml

    # In your docker-compose.yml or docker-compose.override.yml

    services:

      api:

        # ... other service config ...

        volumes:

          # ... other volumes likely exist here ...



          # Add this volume bind:

          - ./mcp-server/search1api-mcp:/app/mcp-server/search1api-mcp

    ```

    *   **Host Path (`./mcp-server/search1api-mcp`):** This is the path on your host machine *relative* to where your `docker-compose.yml` file is located. Adjust it if you cloned the repo elsewhere.

    *   **Container Path (`:/app/mcp-server/search1api-mcp`):** This is the path *inside* the container. It **must match** the directory structure used in the `librechat.yaml` `args` path.



7.  **Restart LibreChat:**

    Apply the changes by rebuilding (if you modified `docker-compose.yml`) and restarting your LibreChat stack.

    ```bash

    docker compose down && docker compose up -d --build

    # Or: docker compose restart api (if only librechat.yaml changed)

    ```



Now, the Search1API server should be available as a tool provider within LibreChat.
