This string is passed to external search services. 27 | - `pageno` (number, optional): Search page number, starts at 1 (default 1) 28 | - `time_range` (string, optional): Filter results by time range - one of: "day", "month", "year" (default: none) 29 | - `language` (string, optional): Language code for results (e.g., "en", "fr", "de") or "all" (default: "all") 30 | - `safesearch` (number, optional): Safe search filter level (0: None, 1: Moderate, 2: Strict) (default: instance setting) 31 | 32 | - **web_url_read** 33 | - Read and convert the content from a URL to markdown with advanced content extraction options 34 | - Inputs: 35 | - `url` (string): The URL to fetch and process 36 | - `startChar` (number, optional): Starting character position for content extraction (default: 0) 37 | - `maxLength` (number, optional): Maximum number of characters to return 38 | - `section` (string, optional): Extract content under a specific heading (searches for heading text) 39 | - `paragraphRange` (string, optional): Return specific paragraph ranges (e.g., '1-5', '3', '10-') 40 | - `readHeadings` (boolean, optional): Return only a list of headings instead of full content 41 | 42 | ## Configuration 43 | 44 | ### Setting the SEARXNG_URL 45 | 46 | The `SEARXNG_URL` environment variable defines which SearxNG instance to connect to. 47 | 48 | #### Environment Variable Format 49 | ```bash 50 | SEARXNG_URL=<protocol>://<hostname>[:<port>] 51 | ``` 52 | 53 | #### Examples 54 | ```bash 55 | # Local development (default) 56 | SEARXNG_URL=http://localhost:8080 57 | 58 | # Public instance 59 | SEARXNG_URL=https://search.example.com 60 | 61 | # Custom port 62 | SEARXNG_URL=http://my-searxng.local:3000 63 | ``` 64 | 65 | #### Setup Instructions 66 | 1. Choose a SearxNG instance from the [list of public instances](https://searx.space/) or use your local environment 67 | 2. Set the `SEARXNG_URL` environment variable to the complete instance URL 68 | 3. If not specified, the default value `http://localhost:8080` will be used 69 | 70 | ### Using Authentication (Optional) 71 | 72 | If you are using a password protected SearxNG instance you can set a username and password for HTTP Basic Auth: 73 | 74 | - Set the `AUTH_USERNAME` environment variable to your username 75 | - Set the `AUTH_PASSWORD` environment variable to your password 76 | 77 | **Note:** Authentication is only required for password-protected SearxNG instances. See the usage examples below for how to configure authentication with different installation methods. 78 | 79 | ### Proxy Support (Optional) 80 | 81 | The server supports HTTP and HTTPS proxies through environment variables. This is useful when running behind corporate firewalls or when you need to route traffic through a specific proxy server. 82 | 83 | #### Proxy Environment Variables 84 | 85 | Set one or more of these environment variables to configure proxy support: 86 | 87 | - `HTTP_PROXY`: Proxy URL for HTTP requests 88 | - `HTTPS_PROXY`: Proxy URL for HTTPS requests 89 | - `http_proxy`: Alternative lowercase version for HTTP requests 90 | - `https_proxy`: Alternative lowercase version for HTTPS requests 91 | 92 | #### Proxy URL Formats 93 | 94 | The proxy URL can be in any of these formats: 95 | 96 | ```bash 97 | # Basic proxy 98 | export HTTP_PROXY=http://proxy.company.com:8080 99 | export HTTPS_PROXY=http://proxy.company.com:8080 100 | 101 | # Proxy with authentication 102 | export HTTP_PROXY=http://username:[email protected]:8080 103 | export HTTPS_PROXY=http://username:[email protected]:8080 104 | ``` 105 | 106 | **Note:** If no proxy environment variables are set, the server will make direct connections as normal. See the usage examples below for how to configure proxy settings with different installation methods. 107 | 108 | ### [NPX](https://www.npmjs.com/package/mcp-searxng) 109 | 110 | ```json 111 | { 112 |

You can see the full documentation [here](https://www.mcpevals.io/docs). 642 | 643 | ```bash 644 | SEARXNG_URL=SEARXNG_URL OPENAI_API_KEY=your-key npx mcp-eval evals.ts src/index.ts 645 | ``` 646 | 647 | ## For Developers 648 | 649 | ### Contributing to the Project 650 | 651 | We welcome contributions!
