Connects Claude to the IETF RFC Editor archive with full text retrieval, metadata lookups, errata queries, and BCP/STD document mappings. Runs through Pipeworx's hosted gateway, so you can ask natural language questions via ask_pipeworx instead of calling tools directly. Useful when you're researching protocol specs, checking official standards documents, tracking RFC status changes, or need to verify technical details from authoritative internet standards. The gateway handles tool selection and argument mapping, which saves you from manually constructing RFC numbers and search parameters. Part of a larger 250+ data source collection, but works standalone if you only need RFC access.
RFC Editor MCP — fetch full RFC text + metadata directly from rfc-editor.org (complementary to ietf-datatracker which deals in metadata). Keyless.
Part of Pipeworx — an MCP gateway connecting AI agents to 1476+ live data sources.
rfc_text(number) — full RFC plain textrfc_metadata(number) — RFC index entry metadata (title, authors, status, obsoletes/updates)errata(number?) — known errata (per-RFC or all)bcp(number) — Best Current Practice mapping (BCP → RFC list)std(number) — STD mapping (STD → RFC list)search(query, status?) — substring search in title/abstract via rfc-editor indexhttps://www.rfc-editor.org/rfc/rfc<N>.txt etc., plus the rfc-index.xml + errata feed.
Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):
{
"mcpServers": {
"rfc-editor": {
"url": "https://gateway.pipeworx.io/rfc-editor/mcp"
}
}
}
tools/list at https://gateway.pipeworx.io/rfc-editor/mcp returns the tools in the table
above plus the shared Pipeworx meta-tools — ask_pipeworx,
discover_tools, search_within, remember/recall and the rest of the
gateway-wide set. So the tool count you see is larger than this table: a
single-pack endpoint currently lists roughly 30 shared tools alongside the
pack's own. The connection's initialize response states its exact scope, and
is the authoritative answer for a given day.
This is deliberate, not multiplexing by accident. The meta-tools are what let a
scoped connection answer a question this pack does not cover — via
ask_pipeworx, which routes across the whole catalog — without you adding a
second MCP server. There is currently no way to mount a pack endpoint without
them; if the extra schemas cost you more context than the routing is worth,
connect to the full gateway once rather than to several pack endpoints.
Or connect to the full Pipeworx gateway to get every pack's tools listed directly, instead of just this one's:
{
"mcpServers": {
"pipeworx": {
"url": "https://gateway.pipeworx.io/mcp"
}
}
}
Both URLs reach the same gateway and the same 1476+ data sources. The
only difference is which pack's tools are listed directly; ask_pipeworx
reaches all of them from either one.
Instead of calling tools directly, you can ask questions in plain English — this works on the pack endpoint above as well as on the full gateway:
ask_pipeworx({ question: "your question about Rfc Editor data" })
The gateway picks the right tool and fills the arguments automatically.
