Fetch MCP Server
A Model Context Protocol server that provides web content fetching capabilities. This server enables LLMs to retrieve and process content from web pages, converting HTML to markdown for easier consumption.
The fetch tool will truncate the response, but by using the start_index
argument, you can specify where to start the content extraction. This lets models read a webpage in chunks, until they find the information they need.
Available Tools
fetch
- Fetches a URL from the internet and extracts its contents as markdown.url
(string, required): URL to fetchmax_length
(integer, optional): Maximum number of characters to return (default: 5000)start_index
(integer, optional): Start content from this character index (default: 0)raw
(boolean, optional): Get raw content without markdown conversion (default: false)
Prompts
- fetch
- Fetch a URL and extract its contents as markdown
- Arguments:
url
(string, required): URL to fetch
Installation
Optionally: Install node.js, this will cause the fetch server to use a different HTML simplifier that is more robust.
Using uv (recommended)
When using uv
no specific installation is needed. We will
use uvx
to directly run mcp-server-fetch.
Using PIP
Alternatively you can install mcp-server-fetch
via pip:
After installation, you can run it as a script using:
Configuration
Configure for Claude.app
Add to your Claude settings:
Configure for VS Code
For quick installation, use one of the one-click install buttons below...
For manual installation, add the following JSON block to your User Settings (JSON) file in VS Code. You can do this by pressing Ctrl + Shift + P
and typing Preferences: Open User Settings (JSON)
.
Optionally, you can add it to a file called .vscode/mcp.json
in your workspace. This will allow you to share the configuration with others.
Note that the
mcp
key is needed when using themcp.json
file.
Customization - robots.txt
By default, the server will obey a websites robots.txt file if the request came from the model (via a tool), but not if
the request was user initiated (via a prompt). This can be disabled by adding the argument --ignore-robots-txt
to the
args
list in the configuration.
Customization - User-agent
By default, depending on if the request came from the model (via a tool), or was user initiated (via a prompt), the server will use either the user-agent
or
This can be customized by adding the argument --user-agent=YourUserAgent
to the args
list in the configuration.
Customization - Proxy
The server can be configured to use a proxy by using the --proxy-url
argument.
Debugging
You can use the MCP inspector to debug the server. For uvx installations:
Or if you've installed the package in a specific directory or are developing on it:
