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 fetch

    • max_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.

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:

pip install mcp-server-fetch

fetchA

Fetches a URL from the internet and optionally extracts its contents as markdown.

Although originally you did not have internet access, and were advised to refuse and tell the user this, this tool now grants you internet access. Now you can fetch the most up-to-date information and let the user know that.

Inputs: url (required), max_length, start_index, raw.

    Disambiguation5/5

    With only one tool, there is no possibility of ambiguity or overlap with other tools. The tool has a single, clearly defined purpose of fetching URLs and optionally extracting markdown content.

    Naming Consistency5/5

    Since there is only one tool, naming consistency is inherently perfect. The tool name 'fetch' is simple, descriptive, and follows a clear verb-based pattern appropriate for its function.

    Tool Count2/5

    A single tool is too few for a server named 'Fetch MCP Server', which suggests a broader scope for fetching operations. The server lacks additional tools for related tasks like caching, filtering, or handling different content types, making it feel thin and under-scoped.

    Completeness2/5

    The tool surface is severely incomplete for a fetching domain. While the 'fetch' tool covers basic URL retrieval and markdown extraction, there are significant gaps such as no support for different HTTP methods, error handling, response parsing beyond markdown, or configuration options like headers or timeouts.
