looker-dev

looker-dev is an MCP server for Claude Code from gemini-cli-extensions/looker. Its token cost is not measured, scanned A, a copy of looker, Apache-2.0.

A command-line server that connects Looker, a business-intelligence platform, to a toolbox interface. It reads connection settings such as the Looker address and client credentials from environment variables.

In plain words
What is it for?
It is for starting the Looker development server and configuring its URL, credentials, SSL checking, and visibility of hidden models, explorations, and fields.
Why use it?
It provides a local way to expose Looker through the toolbox without requiring the connection details to be written directly into the command.

Security

Grade A, and why

looker-dev 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 2d 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.

Origin

This is a copy

94% identical to looker — 4 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

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.
