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

yahboom-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 2mo 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

yahboom-mcp — Claude Code Guide

Overview

SOTA 2026 Yahboom Raspbot v2 ROS 2 MCP Server (FastMCP 3.4 + FastAPI Unified Gateway).

Entry Points

  • uv run yahboom-mcp → yahboom_mcp:main (CLI: --mode stdio|http|dual, --port 10892)
  • start.ps1 → dual-mode gateway on 10892 (webapp 10893)
  • just serve / just test / just lint / just fix

Standards

  • FastMCP 3.4 portmanteau tool pattern — tools use an operation enum param
  • Responses: structured dicts with success, message, domain-specific fields
  • Dual transport: stdio (Claude Desktop) + HTTP (--mode dual)
  • Five-gate: ruff check + ruff format --check + pyright src/ + pytest + webapp tsc/biome
  • Session-context injection lives in .claude-plugin/ and .cursorrules
  • See mcp-central-docs for fleet-wide coding standards

Key Files

  • README.md — full documentation
  • docs/ — CONFIGURATION, DEVELOPMENT, TOOLS, TROUBLESHOOTING, ONBOARDING + ops/hardware
  • pyproject.toml — build config, entry points, ruff/pyright/coverage gates
  • src/yahboom_mcp/server.py — Unified Gateway, REST routes, MCP tools, main()
  • src/yahboom_mcp/portmanteau.py — yahboom_tool dispatch
  • native/ — Tauri 2 NSIS desktop shell (embedded backend)
  • AGENTS.md — OpenAI Codex agent context (if present)
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.
