Get Started
Docker
💡 Recommended for evaluation purposes (Local Python or Node are not required)
docker run -p 5000:5000 -it falkordb/queryweaver
Launch: http://localhost:5000
Use an .env file (Recommended)
Create a local .env by copying .env.example and passing it to Docker. This is the simplest way to provide all required configuration:
cp .env.example .env # edit .env to set your values, then: docker run -p 5000:5000 --env-file .env falkordb/queryweaver
Alternative: Pass individual environment variables
If you prefer to pass variables on the command line, use -e flags (less convenient for many variables):
docker run -p

Questions
What is the QueryWeaver MCP server?
An open-source Text2SQL tool that transforms natural language into SQL using graph-powered schema understanding. Ask your database questions in plain English, QueryWeaver handles the weaving.
Is QueryWeaver safe to connect to an agent?
No — not without reading the findings first. The audit graded it D (61/100) and found 1 critical or high issue in the source. Each one is listed on this page with the file and line it is on.
What credentials does QueryWeaver need?
It reads ANTHROPIC_API_KEY, AZURE_API_KEY, COHERE_API_KEY, EMAIL_AUTH_ENABLED, FASTAPI_SECRET_KEY, GEMINI_API_KEY, GITHUB_CLIENT_SECRET, GOOGLE_CLIENT_SECRET, MAIL_PASSWORD, OAUTH_BASE_URL, OPENAI_API_KEY and TEST_USER2_PASSWORD from the environment. Give it a token scoped to the least it needs — an agent that can be talked into calling a tool can be talked into calling it with your credentials.
How does QueryWeaver run?
It speaks streamable-http, so it runs as a service you connect to over the network. It is published on PyPI as queryweaver.
How current is this page?
The grade is for one exact copy of the source (2a55c41d7ed2), read on 2026-09-25. The repository is watched and re-audited when it changes.
