approval_resolve · AIOS Co-Founder MCP: Risk & Policy

WHAT IT DOES

What approval_resolve does on AIOS Co-Founder MCP

AI agents invoke approval_resolve to trigger actions in AIOS Co-Founder MCP. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why approval_resolve needs a policy

This tool controls the approval gating mechanism described in the server description for 'sensitive operations.' Resolving an approval can trigger any downstream action (e.g., sending emails, modifying calendar events, updating contacts). The actual effect depends on what was gated, but the act of approving/denying directly enables execution of those sensitive operations.

From the tool's definition 'Approve or deny an action' — resolves a pending approval gate, triggering or blocking a downstream operation

Verdict

approval_resolve Rate-limited

approval_resolve stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
