Use cases

Use cases include programmatically retrieving specific RFCs, searching for RFCs based on keywords, and extracting particular sections from RFC documents for analysis or integration into applications.

How to use

To use mcp-rfc, configure your MCP settings file to include the server, and utilize available tools such as get_rfc, search_rfcs, and get_rfc_section to interact with RFC documents.

Key features

Key features include fetching RFC documents by number, searching for RFCs by keyword, extracting specific sections, parsing both HTML and TXT formats, and caching for improved performance.

Where to use

mcp-rfc can be used in software development, research, and any domain requiring access to RFC documents and related information.

Implementation Details

The server implements two main components:

1. RFC Service: Handles fetching, parsing, and extracting data from RFCs
2. MCP Server: Implements the MCP protocol and exposes tools and resources

The RFC service supports both HTML and TXT format RFCs, attempting to use HTML first for better structure, then falling back to TXT format if needed.
