Overview

What is Rfcxml Mcp?

Rfcxml Mcp is a Model Context Protocol (MCP) server for structured understanding of RFC documents. It leverages the semantic structure of RFCXML to extract normative requirements (MUST/SHOULD/MAY), build dependency graphs, manage definition scopes, and generate implementation checklists. It is designed for AI assistants and human developers who need precise analysis of RFC specifications.

How to use Rfcxml Mcp?

Add the server to your MCP configuration file (Claude Desktop or Claude Code) using the command npx -y @shuji-bonji/rfcxml-mcp. Optionally install globally via npm install -g @shuji-bonji/rfcxml-mcp and use rfcxml-mcp as the command. Tools are invoked through the MCP client.

FAQ from Rfcxml Mcp

How is Rfcxml Mcp different from existing text-based RFC MCP servers?

Unlike text-based servers, it uses RFCXML structural data to extract requirements, conditions, exceptions, dependencies, and checklists that are not available from plain text.

How does Rfcxml Mcp handle RFCs published before RFC 8650?

It has automatic fallback – when official RFCXML is not available, it parses the text format instead, with a note indicating reduced accuracy.

What source information is included in the response?

Every response includes a _source field ("xml" or "text") and a _sourceNote when text fallback is used, so you know the reliability of the data.

What tools does Rfcxml Mcp provide?

Tools include get_rfc_structure, get_requirements, get_definitions, get_rfc_dependencies, get_related_sections, validate_statement, and generate_checklist.

How do I configure Rfcxml Mcp with Claude Desktop or Claude Code?

Add the server entry to your MCP config file (e.g., ~/Library/Application Support/Claude/claude_desktop_config.json on macOS) with command npx -y @shuji-bonji/rfcxml-mcp.
