RFC Editor

mcp-name: io.github.daedalus/mcp-rfc-editor

An MCP (Model Context Protocol) server for editing RFC TXT documents using the rfc-editor Python library.

Installation

pip install mcp-rfc-editor

Usage

CLI

python -m mcp_rfc_editor

Programmatic

from mcp_rfc_editor import main
main()

MCP Tools

The server exposes the following tools:

• load_rfc - Load and parse an RFC TXT file (creates session)
• download_rfc - Download an RFC from rfc-editor by ID (creates session)
• create_rfc - Create a new empty RFC document (creates session)
• get_document - Get the current document from session context
• save_rfc - Save an RFC document to TXT format
• set_title - Set the document title
• set_abstract - Set the document abstract
• add_section - Add a new section
• update_section - Update an existing section
• delete_section - Delete a section
• list_sections - List all sections in the document
• set_copyright - Set copyright notice
• set_authors - Set document authors
• to_dict - Convert document to dictionary

Session-Based Workflow

The server maintains session context so you don't need to pass the full document object on every call:

# 1. Download an RFC - returns Session ID
result = download_rfc(rfc_id="791")
# Returns: {document..., "Session ID": "abc-123"}

# 2. Use session ID to get title (no document needed)
get_title(session_id="abc-123")

# 3. Modify and changes are persisted
set_title(session_id="abc-123", title="New Title")

Alternatively, you can always pass the full document object directly (legacy mode).
