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

engrava-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 1mo 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.

CLAUDE.md — engrava-mcp

This is a public repository (engrava-mcp) — Model Context Protocol server exposing Engrava as agent memory.

Assume every commit message, PR title, PR body, branch name, code comment, and docstring is world-visible. Public-safe by default.

Context

Aspect Value
License MIT
Primary language python 3.11+
Default branch for PRs the active release/vX.Y.Z branch
Release flow Manual version in pyproject.toml and server.json + maintainer-created vX.Y.Z tag on main
Contribution model issues + PRs on GitHub

Repository-specific rules

  • Thin MCP server: consume Engrava's public API only — no internals access.
  • Transport: stdio; the surface is MCP tools / resources / prompts.
  • Store resolution via env vars (ENGRAVA_MCP_CONFIG, ENGRAVA_DB_PATH, ENGRAVA_MCP_READ_ONLY).
  • Quality gate: ruff ALL + mypy strict + 90% test coverage.

Code quality — zero-compromise bar

This is production code maintained to a high quality bar. A feature is not "done" until every point below holds:

  • Linting — ruff check clean, ruff format --check clean, no rule disables without a justifying comment.
  • Typing — mypy --strict clean. No bare Any. No # type: ignore without a justifying inline comment.
  • Coverage — 90% minimum, enforced by --cov-fail-under=90. TDD preferred; tests are first-class code.
  • Docstrings — Google-style on every public symbol (params, returns, raises, examples).
  • Domain modelling — concrete types per concept, no catch-all dicts, no god objects.
  • Errors — typed exceptions; never bare except; never swallow errors silently.
  • No shortcuts — no TODO/FIXME/HACK in production code; open an issue instead. No dead code. No magic strings.
  • Secrets — never hard-code API keys; use env vars or config objects; never log secrets.

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.
