agloop_set_phase · Agloop MCP: Risk & Policy

WHAT IT DOES

What agloop_set_phase does on Agloop

AI agents use agloop_set_phase to create or update resources in Agloop — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Agloop environment.

WHY IT NEEDS A POLICY

Why agloop_set_phase needs a policy

The tool modifies the agent's current phase state, which is a reversible write operation. It transitions the agent framework to a new phase, altering system state but not irreversibly destroying data. The 'COORDINATOR ONLY' restriction suggests it has meaningful impact on agent orchestration, raising severity to medium.

From the tool's definition Transition to a new phase. COORDINATOR ONLY.

Verdict

agloop_set_phase Rate-limited

agloop_set_phase stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches Agloop, so you can run agents against it safely.

FAQ

Questions about agloop_set_phase

What does the agloop_set_phase tool do? +

Transition to a new phase. COORDINATOR ONLY. It is categorised as a Write tool in the Agloop MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on agloop_set_phase? +

Register the Agloop MCP server in PolicyLayer and add a rule for agloop_set_phase: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Agloop. Nothing to install.

What risk level is agloop_set_phase? +

agloop_set_phase is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit agloop_set_phase? +

Yes. Add a rate_limit block to the agloop_set_phase rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block agloop_set_phase completely? +

Set action: deny in the PolicyLayer policy for agloop_set_phase. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides agloop_set_phase? +

agloop_set_phase is provided by the Agloop MCP server (zebbern/agloop-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
