Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.04343 | $0.04343 |
| Opus 5.5 | $0.01737 | $0.01737 |
| Sonnet 5.5 | $0.00869 | $0.00869 |
| Haiku 4.5 | $0.00434 | $0.00434 |
Grade A, and why
vibo-mcp CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 294 lines — stays where its author put it; the contents beside it link to each section on GitHub.
vibo-mcp
MCP server for Vibo. Wraps the Vibo consumer GraphQL API
(https://api.vibodj.com/v2/graphql) and exposes 42 host/couple tools to Claude
over stdio (15 reads + 27 writes/actions, confirmation-gated where they mutate). Built on @chrischall/mcp-utils
(runMcp, minifiedResult, toolAnnotations, confirmWrite, error classes).
Commands
npm run build # tsc + esbuild bundle → dist/index.js + dist/bundle.js
npm test # vitest run
npm run test:watch # vitest watch
npm run test:coverage # vitest run --coverage (v8 reporter, no thresholds)
Run locally (requires built dist/ + credentials):
[email protected] VIBO_PASSWORD=… node dist/index.js
Tool naming
All tools are prefixed vibo_ (e.g. vibo_list_sections, vibo_add_song_to_section).
Architecture
src/
version.ts # single source of truth for VERSION (x-release-please-version)
index.ts # entry — runMcp({ name, version, banner, tools })
client.ts # ViboClient — GraphQL POST w/ x-token, deferred config error,
# single-flight login + refresh-on-expiry + replay-once;
# gqlUpload() for multipart (Upload scalar);
# adoptVerifiedTokens() verifies a browser-captured pair on an
# isolated client before adopting it (never the env login,
# never session.json — the tool persists after it succeeds)
auth.ts # captureViboSession() — fetchproxy browser-bridge token capture (SSO)
session-store.ts# persist {accessToken,refreshToken} to ~/.vibo-mcp/session.json (0600)
gql.ts # all GraphQL operation documents (selections from introspection)
reorder.ts # planMoves() — "move these after X" as single-item reorder
# calls (Vibo: source lands after target; null = first)
brief.ts # view: "brief" lines (title — date — status, ≤ 120 chars,
# "-- " note lines) in the untrusted-data envelope
song-search.ts # pure search-quality heuristics — parseSearchQuery, assessSong,
# annotateSearchResults; grades each search hit
# likely-original / uncertain / likely-not-original
tools/
profile.ts # vibo_get_me, vibo_healthcheck
events.ts # list_events, get_event, join_event, leave_event, create_event_contact
sections.ts # vibo_list_sections
songs.ts # get_section_songs, search_songs, add_song_to_section, toggle_song_like
playlists.ts # get_playlists, get_playlist_songs, export_event_to_{spotify,apple_music}
notifications.ts # list_notifications, get_notifications_count, mark_notifications_read
questions.ts # list_section_questions, answer_question (incl. image/file uploads)
song-management.ts # remove_song_from_section, update_song, move_song, reorder_songs
comments.ts # comment_on_song/section, delete_song/section_comment
ideas.ts # list_section_song_ideas, list_song_ideas_songs
imports.ts # import_playlist_to_section
collaboration.ts # list_event_users, invite_users, change_user_role, remove_user
section-edit.ts # update_section
section-manage.ts # create_section, delete_section, reorder_sections
lookups.ts # read-before-write helpers (sections, event perms,
# section song ids, id validation)
uploads.ts # set_profile_photo
session.ts # capture_session (SSO browser token capture)
shared.ts # pagination + confirmWrite (confirmation gate) helpers
hints.ts # familyMeta() — context-group `_meta.mint` hints
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
