Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

vibecompass-mcp AGENTS.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 24d 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.

What it actually says

VibeCompass MCP

Project memory lives in this repo's workspace, not in the repo. From a main checkout the workspace is ..; from a lane worktree (<workspace>/worktrees/<lane-id>/<repo-id>/) it is ../../.., and ../.vibecompass-lane.yaml names the lane's memory root (memory_root). Read the workspace AGENTS.md first: it names the canonical root and the session protocol. Architecture docs are under <workspace>/vibecompass-docs/architecture/.

Repo Purpose

This package is the local MCP client/server layer that exposes VibeCompass context to AI tools over stdio.

Working Rules

  • Keep tool contracts aligned with vibecompass-app /api/mcp/* endpoints
  • Read tools should stay resilient and never hard-fail the user session
  • Write tools should surface failures clearly
  • Preserve TypeScript ESM / NodeNext conventions

Commands

  • npm run build
  • npm run dev
  • npm run start

Important Context

  • Runtime env:
    • hosted mode: VIBECOMPASS_API_KEY, optional VIBECOMPASS_API_URL
    • local read mode: VIBECOMPASS_ROOT
    • hybrid mode: if both are set, read tools use the local root while write tools and hosted conflict reads stay enabled through the API client
  • Current architecture and behavior decisions live in:
    • <workspace>/vibecompass-docs/decisions/mcp-server.md
    • <workspace>/vibecompass-docs/architecture/mcp-server/
Changes

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.
