mcp-server-questdb

mcp-server-questdb is an MCP server for Claude Code, Codex, Cursor, Gemini CLI, OpenCode from questdb/mcp-server-questdb. Its token cost is not measured, scanned A, original, Apache-2.0.

An MCP server that connects coding agents to a running QuestDB Web Console. QuestDB is a database designed for time-stamped data, and MCP lets an agent use connected tools.

In plain words
What is it for?
Use it to run SQL queries, work with notebook cells, and create charts in QuestDB.
Why use it?
It avoids switching between the coding agent and QuestDB for database exploration. The connection requires four environment variables and a locally running console.

Security

Grade A, and why

mcp-server-questdb 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 4d 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.
