magpie-dataset

magpie-dataset is an MCP server for Claude Code from TimSimpsonJr/magpie. Its token cost is not measured, scanned A, original, MIT.

A local service that lets a coding agent work with SQLite database files, including optional metadata used by Datasette, a tool for publishing and exploring data.

In plain words
What is it for?
Use it to analyze the SQLite dataset stored in the project’s .magpie folder and run predefined dataset queries.
Why use it?
It gives the agent a defined way to inspect and query a project database without relying on a remote database service.

MCP server for Claude Code

Written for Claude Code: ${CLAUDE_PROJECT_DIR} variable. Also seen: listed in a Claude config.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

Security

Grade A, and why

magpie-dataset 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.

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.
