Built from this server's own package name, version and transport as found in its source — not copied from anyone's documentation, so it cannot drift against a page we do not control. Replace the environment placeholders with a token scoped to the least it needs.

Questions
What tools does Tinybird expose?
11 in total: 7 read-only, 4 that write, and 0 that can delete or overwrite. Every one is listed on this page with its risk.
Is Tinybird 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 Tinybird need?
It reads TB_ADMIN_TOKEN and TINYBIRD_SIGNING_KEY 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 Tinybird run?
It speaks stdio, so it runs as a local process your client starts. It is published on npm as bluesky-demo at 0.1.0.
How current is this page?
The grade is for one exact copy of the source (0e4a5e0fa832), read on 2026-10-07. The repository is watched and re-audited when it changes.
