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

tai42-mcp-dynamic-postgres 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 today.

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

AGENTS.md

Contributor and agent rules for this repository. Terse by design.

Commits

Conventional Commits. The type sets the release:

Type Release
fix: patch
feat: minor
feat!: or a BREAKING CHANGE: footer major
chore: docs: test: ci: refactor: perf: build: style: none

release-please parses merged commits and raises a release PR; a human merges it, which tags v<version> and publishes. Non-conforming commits and PR titles fail the commitlint check.

Build, test, lint

uv sync --locked --python 3.13 --extra dev
uv run ruff check .
uv run ruff format --check .
uv run pyright
uv run --python 3.13 pytest --cov --cov-report=term-missing
uv sync --locked --python 3.13 --extra dev --extra test-integration
uv run pytest -m integration

Comments and docs

Terse, constraint-only, present tense. State the constraint and why it holds, not what changed. No history notes and no ticket references in comments.

Rules

  • Release notes are generated onto the GitHub Release from commit messages; release-please is configured with skip-changelog, so CHANGELOG.md stays the empty stub.
  • Loud errors: a failure is fatal. No silent fallbacks, no || true, no swallowed exceptions, no compatibility shims.
  • The workflows under .github/workflows/ are the source of truth for commands; keep this file in step with them.
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.
