What is steampipe-mcp-server CLAUDE.md?

A project instruction file for a Python server that connects coding agents to Steampipe databases. It documents how to build, run, test, lint, format, and type-check the project.

Use it when developing or maintaining this server, especially for installing dependencies, running it locally, executing tests, checking code quality, and understanding its source directories.

It gives contributors one place to find the repository’s expected commands, layout, Python version, and coding rules. Steampipe is a system that lets SQL query services and external data sources.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00474	$0.00474
Opus 5	$0.00237	$0.00237
Sonnet 5	$0.00095	$0.00095
Haiku 4.5	$0.00047	$0.00047

Security

Grade A, and why

steampipe-mcp-server 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 9d 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.

Create a git tag: git tag v0.1.0 and push: git push origin v0.1.0

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.
