Questions about Biel Ai MCP server

What is the Biel Ai MCP server?
Connect AI tools like Cursor, VS Code, and Claude to your product docs.
Is Biel Ai safe to connect to an agent?
The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B.
What credentials does Biel Ai need?
No credential environment variables were found in its source, so it appears to need none.
How does Biel Ai run?
It speaks sse and streamable-http, so it runs as a service you connect to over the network. It is published on PyPI as biel-mcp.
How current is this page?
The grade is for one exact copy of the source (61e93b89185d), read on 2026-09-19. The repository is watched and re-audited when it changes.
