Q: What risk level is register?

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

WHAT IT DOES

What register does on Claude Senator

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

WHY IT NEEDS A POLICY

Why register needs a policy

Registration is a reversible write operation that creates or updates metadata about this Claude instance in a shared network system. It modifies the state of the Senator network but does not execute arbitrary code, delete data, or cause financial impacts.

From the tool's definition Tool name is 'register' and description states it explicitly registers a Claude instance in the Senator network and updates instance metadata. This is a write operation that creates or modifies state in the network by enrolling/updating a Claude instance.

Verdict

register 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.

FAQ

Questions about register

What does the register tool do? +

Explicitly register this Claude instance in the Senator network. Usually automatic, but useful for troubleshooting or updating instance metadata. It is categorised as a Write tool in the Claude Senator MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on register? +

Register the Claude Senator MCP server in PolicyLayer and add a rule for register: 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 Claude Senator. Nothing to install.

What risk level is register? +

Can I rate-limit register? +

Yes. Add a rate_limit block to the register 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 register completely? +

Set action: deny in the PolicyLayer policy for register. 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 register? +

register is provided by the Claude Senator MCP server (vvkmnn/claude-senator-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
