About MCP-Server-IETF

MCP-Server-IETF gives LLMs access to IETF RFCs, with title search, paginated retrieval, and cached indexes and documents.

Key features

  1. 01Download and cache RFC indexes and documents
  2. 02Search RFCs by title keywords
  3. 03Read RFC documents with pagination
  4. 04Extract metadata such as page numbers

Use cases

  1. 01Find RFCs containing specific title keywords
  2. 02Read long RFCs in sections
  3. 03Provide standards text to an LLM

MCP support

This MCP server exposes tools to MCP clients for counting, retrieving, and searching RFC documents.

Configuration

Local server config is the same for every client. Copy it into your client’s MCP config file.

mcp.json · Universal config
{
  "mcpServers": {
    "ietf": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/inspector"
      ]
    }
  }
}
Run commandnpx -y @modelcontextprotocol/inspector

Local servers need a runtime on your machine (e.g. Node.js 18+). Config file locations differ by client; see your client’s docs.

Packages
npm@modelcontextprotocol/inspector

Tools

Local servers expose tools only once running on your machine, and the maintainer has not provided a tool list.

MCP-Server-IETF

A Model Context Protocol server for fetching IETF documents (RFCs) for Large Language Models.

Overview

This project implements a Model Context Protocol (MCP) server that provides access to IETF RFC documents. It enables Large Language Models to access RFC specifications through a standardized interface.

Key features:

  • Download and cache RFC index and documents
  • Search RFCs by keyword in titles
  • Access RFC documents with pagination support
  • Extract metadata like page numbers from documents

Installation

Requirements
  • Python 3.11 or higher
  • Dependencies as listed in pyproject.toml
Install from source
# Clone the repository
git clone https://github.com/tizee/mcp-server-ietf
cd mcp-server-ietf

# Install with pip
pip install -e .

Usage

Starting the server
# Start the server
mcp-server-ietf

Or use it with the MCP inspector:

npx @modelcontextprotocol/inspector uv run mcp-server-ietf
Available Tools

When connected to the server, the following tools are available:

list_docs_number

Get the total number of RFC documents available in the index.

get_doc

Get an RFC document by its number with pagination support.

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
