Provides access to IETF RFC documents for Large Language Models via the Model Context Protocol.
If you already use IETF Document Server, the ietf document server mcp server is the piece that lets your assistant work with it directly. Provides access to IETF RFC documents for Large Language Models via the Model Context Protocol.
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.
The toolset is worth reading before you wire it up, because it tells you what the integration is really for:
Requirements — The Requirements tool exposed by this serverlist_docs_number — Get the total number of RFC documents available in the indexget_doc — Parameters: - number: The RFC number (e.g., "1234") - start_line: The line number to start from (default: 1) - max_lines: Maximum number of lines tosearch_rfc_by_keyword — Parameters: - keyword: The search term to look for in RFC titlespyproject.tomlInstallation goes through your MCP client rather than a global install: point it at @modelcontextprotocol/inspector on npm and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.
Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. IETF Document Server's toolset — Requirements, list_docs_number, get_doc and 1 more — is a fair guide to whether it matches your workflow. It is maintained by tizee; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
