k1_place · Execution Market MCP: Risk & Policy

WHAT IT DOES

What k1_place does on Execution Market

AI agents invoke k1_place to trigger actions in Execution Market. 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.

k1_place Rate-limited

k1_place 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.
