Why it got a B

TaskBullet's own MIT-licensed TypeScript server. It gives an agent 13 tools: check the hours balance, hand a task to a human virtual assistant, place and track a human phone call (US and Canada numbers, structured answers back), and confirm, cancel or reopen work. It runs locally over stdio through npm, or you can point a cloud agent at the hosted endpoint https://taskbullet.com/api/agent-mcp. The repo and npm show no advisories, and the source has no shell-outs. A second endpoint, /api/mcp, is a read-only site guide that needs no key. Biggest deduction: every call rests on one unscoped tb_live_ API key that can spend paid hours and place calls, so the grade stops at B; keep a small balance on the account and read each brief before the agent sends it. One human maintainer.

Is TaskBullet MCP Server safe?

Is TaskBullet MCP Server safe to use?

TaskBullet MCP Server grades B (solid, with minor gaps). Login is required, but access is coarse: one sign-in or key covers more than your agent needs, so grant the narrowest account you can. Upkeep is hard to verify (closed source or a single maintainer), so pin the version you tested.

Does TaskBullet MCP Server have known vulnerabilities?

Not in our current data: it has no open CVEs or advisories. We re-check as new ones are published.

Does TaskBullet MCP Server support authentication?

Yes. It requires a login, so access can be tied to a person or a scoped key.
