ietf-llm 0.5.1

Maintain a local, LLM-queryable corpus of an IETF Working Group's public record (drafts, mailing list, GitHub issues, meetings), with an MCP server, semantic search, and NotebookLM export.

ietf-llm

Maintain a local, queryable corpus of an IETF Working Group's public record — charter, drafts, RFCs, meeting minutes, slides, transcripts, mailing list archives, and GitHub issues — for use with LLM-based tools.

Two supported workflows:

1. Use it as an MCP server — register ietf-llm-mcp with Claude, Codex, Gemini, Cursor, Zed, etc. and ask questions across any WG you've gathered.
2. Use it with NotebookLM — export the gathered corpus as a directory of clean text files (or push directly to NotebookLM Enterprise) and ingest it as a notebook source set.

Also works with IRTF Research Groups. Pass the RG's shortname (e.g. cfrg, hrpc, pearg) anywhere this README says <wg>.

Note: This package was previously published as ietf-notebook. That distribution is deprecated. See Migrating from ietf-notebook.

Installation

pipx install ietf-llm

Behind a corporate firewall with TLS interception? Install with the certs extra:

pipx install ietf-llm[certs]

---

1. Use as an MCP server

ietf-llm-mcp is a stdio Model Context Protocol server that exposes the local corpus to any MCP-capable agent. Set up once, gather each WG you care about once, then ask questions indefinitely.

Register the server

Pick your client. The snippets below are correct as of writing — if your client has changed since, its own MCP docs are authoritative.

Gotcha (all clients): if ietf-llm-mcp was installed via pipx, the binary is on your shell PATH but may not be on the PATH inherited by a GUI app launched from Finder / Spotlight / Explorer. Use the absolute path (which ietf-llm-mcp) if the client can't find the command.

Claude Code

claude mcp add ietf-llm -- ietf-llm-mcp

Also install the bundled skill so Claude knows how to drive the tools well (digests before raw reads, search before slurping mailing-list files, etc.):

ietf-llm --install-claude-skill

Re-run after upgrading the package to pick up improvements.

Claude Desktop

Edit claude_desktop_config.json (create it if missing):

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "ietf-llm": {
      "command": "ietf-llm-mcp"
    }
  }
}

Quit and relaunch Claude Desktop — the config is only read at startup.

Codex CLI (OpenAI)

~/.codex/config.toml:

[mcp_servers.ietf-llm]
command = "ietf-llm-mcp"

Gemini CLI

~/.gemini/settings.json:

{
  "mcpServers": {
    "ietf-llm": {
      "command": "ietf-llm-mcp"
    }
  }
}

opencode

~/.config/opencode/opencode.json (or opencode.json in your project root):

{
  "$schema": "https://opencode.ai/config.json",
  "mcp": {
    "ietf-llm": {
      "type": "local",
      "command": ["ietf-llm-mcp"],
      "enabled": true
    }
  }
}

Cursor

In-app MCP settings panel, or ~/.cursor/mcp.json (global) or .cursor/mcp.json (per-project):

{
  "mcpServers": {
    "ietf-llm": {
      "command": "ietf-llm-mcp"
    }
  }
}

Zed

~/.config/zed/settings.json:

{
  "context_servers": {
    "ietf-llm": {
      "command": {
        "path": "ietf-llm-mcp",
        "args": []
      },
      "settings": {}
    }
  }
}

Gather a Working Group

Gathering is a slow, network-heavy job, so it runs from the CLI — not silently from the agent. Do it once per WG you want to query:

ietf-llm httpbis \
    --github httpwg/http-core \
    --github httpwg/http-extensions \
    --embed

• --github org/repo — GitHub repos whose issues to include. Repeat per repo. Persisted, so future updates omit it.
• --embed — build the local semantic search index that backs the search_corpus MCP tool. Required if you want the agent to search. Downloads ~130 MB of model weights once on first run.

Everything goes to ~/.cache/ietf-llm/<wg>/. The MCP server reads from there — no separate destination to manage.

Ask your agent

"What's open in httpbis right now?"
"Anyone on the list raised concerns about cookie partitioning?"
"How did the debate on MLKEM evolve in TLS?"

The agent uses list_working_groups, overview, read_digest, search_corpus, and read_topic to answer — no need to point at files. See MCP tools for the full surface.

Updating

Just re-run the gather. All per-WG settings (GitHub repos, embedding choice) are remembered:

ietf-llm httpbis

Embedding is incremental — only changed files are re-embedded. Run on a cron or whenever you want fresh data; the agent picks up the new state on its next tool call.

---

2. Use with NotebookLM

NotebookLM ingests a corpus as a set of source files. ietf-llm-export turns the gathered cache into an upload-ready directory, or pushes straight to a NotebookLM Enterprise notebook.

Workflow note: export always produces a complete fresh dump. Create a new notebook on each refresh rather than trying to merge updates into an existing one.

Gather a Working Group

Same as the MCP path, but --embed is optional (NotebookLM does its own indexing):

ietf-llm httpbis \
    --github httpwg/http-core \
    --github httpwg/http-extensions

Export to a local directory

ietf-llm-export httpbis --destination ~/notebooklm/httpbis

Drag the directory's contents into NotebookLM as sources. Per-thread mailing list conversations and per-issue GitHub records are bundled by year / repo to stay under NotebookLM's 50-source free / 300-source Plus limit.

Export to NotebookLM Enterprise

If you have Google Workspace Enterprise with NotebookLM enabled, ietf-llm-export can create the notebook and upload sources directly:

ietf-llm-export httpbis --create my-gcp-project-id

One-time setup:

1. Google Cloud Project with the Discovery Engine API enabled.
2. OAuth credentials: create an "OAuth 2.0 Client ID" (Desktop App) in the Cloud Console.
3. Save the JSON as client_secrets.json in ~/.config/ietf-llm/ (or pass --credentials-file PATH).

First run opens a browser to authorise; the token is cached at ~/.config/ietf-llm/token.json.

Per-WG export settings are persisted at ~/.config/ietf-llm/<wg>/export.json — subsequent runs of the same mode need only ietf-llm-export <wg>.

Reference

Commands

Command	Job	Reads	Writes
ietf-llm	Gather / refresh a WG	network	cache
ietf-llm-export	Mirror cache to dir, or push to NotebookLM Enterprise	cache	dir / NotebookLM
ietf-llm-search	Semantic search over the cache	cache	stdout
ietf-llm-mcp	Expose the cache to MCP clients	cache	stdio (MCP)

All four are independent. The cache (~/.cache/ietf-llm/<wg>/) is the single source of truth; everything else reads from it.

Gather options

ietf-llm [OPTIONS] <wg_shortname>

• --github OWNER/REPO — repeat per GitHub repo whose issues to gather.
• --draft DRAFT-NAME — extra Internet-Draft to track, beyond the WG's auto-discovered documents (repeatable, persisted). Version suffix is stripped; every revision is gathered.
• --mailing-list LIST — extra IETF-hosted mailing list to sync, beyond the WG's auto-discovered one (repeatable, persisted). Accepts foo or [e-mail].

Synthetic / pre-WG corpora. Prefix the shortname with x- (e.g. ietf-llm x-webbotauth --draft draft-... --mailing-list [e-mail]) to gather a collection of drafts and mailing lists that don't have a formal WG yet. The x- prefix opts out of every Datatracker / WG-page lookup (no charter, no leadership, no auto-discovered drafts, no Datatracker timeline / ballot events) while leaving the rest of the pipeline working as normal — --draft and --mailing-list become the only content sources.

• --github-label LABEL / --exclude-github-label LABEL — filter issues by label; repeatable.
• --months N — months of mailing list / meeting history (default 12).
• --summarize / --summarize-model MODEL — add LLM-generated one-liners to digests via the llm package.
• --embed / --embed-model MODEL — build / refresh the semantic search index (required for ietf-llm-search and the MCP search_corpus tool).
• --rebuild-embeddings — with --embed, drop and re-embed instead of incremental update.
• --clear-cache — wipe the cache for this WG and re-download.
• --clear-config — clear persisted config for this WG.
• --quiet / --verbose.

Per-WG settings are persisted at ~/.config/ietf-llm/<wg>/gather.json.

GitHub auth. Set GITHUB_TOKEN on the gather invocation (a fine- scoped read-only token is plenty); without one you'll hit anonymous API rate limits quickly on large WGs. Prefer inline-passing over exporting in your shell rc so the token doesn't leak into every other subprocess:

GITHUB_TOKEN=ghp_... ietf-llm httpbis
# or, from a secret manager:
GITHUB_TOKEN=$(security find-generic-password -s github-readonly -w) \
    ietf-llm httpbis

Semantic search from the CLI

ietf-llm-search httpbis "skepticism about cookie partitioning" -k 8

Chunks are content-aware: one chunk per mailing list message, one per issue comment, and a windowed slice of drafts/RFCs/transcripts. The index lives at ~/.cache/ietf-llm/<wg>/embeddings.db and updates incrementally on each --embed run.

Default model: sentence-transformers/BAAI/bge-small-en-v1.5 — small (~33M params), MPS-accelerated, runs entirely on your machine. Override with --embed-model <id> for any model the llm package recognises.

Digest files

Every gather produces small markdown digests under ~/.cache/ietf-llm/<wg>/files/digests/:

• index.md — categorised inventory of all cached files.
• issues.md — one row per GitHub issue (state, title, labels, comments, last updated), sorted open-first.
• threads.md — one row per mailing list thread (subject, message count, participants, date range).
• people.md — participants with roles + message counts.
• timeline.md — chronological events (draft publications, issue open/close, meetings, polls, WGLC, …).

Generated deterministically from the cache. Pass --summarize to also include LLM-generated one-liners per row.

MCP tools

ietf-llm-mcp exposes:

• list_working_groups() — WGs gathered locally.
• overview(wg) — chairs, active drafts, top open issues, recent threads, latest meeting. First call for "tell me about X."
• list_labels(wg) — GitHub issue labels with frequencies.
• list_files(wg, pattern?) — file inventory with chunk counts.
• read_digest(wg, kind, ...filters) — index / issues / threads / people / timeline. Filters compose (state, label, author, role, since/until, event_kind, …).
• search_corpus(wg, query, ...) — semantic search with optional state, label, file_pattern, since/until, sort="date", group_by="file".
• read_topic(wg, query, include_replies=False) — chronological narrative view: full message bodies across threads and issues in date order, optionally walking reply descendants.
• get_chunk_text(wg, file, chunk_idx, end_chunk_idx?) — full text of one chunk (or a range).
• get_chunks_batch(wg, [{file, chunk_idx, end_chunk_idx?}, …]) — multi-file batch fetch.
• fetch_by_url(wg, url) — resolve a GitHub or mail-archive URL to its cached content.
• read_file_section(wg, file, start_line, max_lines) — bounded raw read (default 400 lines, hard cap 5000).

Migrating from ietf-notebook

If you previously used the ietf-notebook distribution:

pipx uninstall ietf-notebook
pipx install ietf-llm

Cache and config directories changed names. To preserve a gathered cache, move it by hand:

mv ~/.cache/ietf-notebook  ~/.cache/ietf-llm
mv ~/.config/ietf-notebook ~/.config/ietf-llm

Otherwise the old directories are simply ignored.

Command renames

Before	After
ietf-notebook <wg>	ietf-llm <wg>
(no equivalent)	ietf-llm-export <wg> (split out)
(no equivalent)	ietf-llm-search <wg> <query> (new)
(no equivalent)	ietf-llm-mcp (new)

Flags moved off the gather CLI

These now live on ietf-llm-export:

Old: ietf-notebook <wg> ...	New
--destination DIR	ietf-llm-export <wg> --destination DIR
--create GCP_PROJECT	ietf-llm-export <wg> --create GCP_PROJECT
--credentials-file PATH	ietf-llm-export <wg> --credentials-file PATH
--token-file PATH	ietf-llm-export <wg> --token-file PATH

If you pass any of these to ietf-llm, you'll get a redirect error.

--update is gone

The gather CLI is now idempotent — re-run it whenever you want fresh data. The export CLI always produces a complete fresh dump; for NotebookLM, create a new notebook each refresh rather than trying to merge updates.
