AI agents call chat.status to retrieve information from Signomy without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool only reads and returns current system state information (governance mode, posture, role, vault context, agent presence, cursors). No data is created, modified, deleted, or financial transactions triggered. Pure read/query operation with minimal blast radius if misused.
From the tool's definition Inspect current MO§ES™ governance state: mode, posture, role, loaded vault context, agent presence, and message cursors
Attacks that exploit this kind of access
Inspect current MO§ES™ governance state: mode, posture, role, loaded vault context, agent presence, and message cursors. It is categorised as a Read tool in the Signomy MCP Server, which means it retrieves data without modifying state.
Register the Signomy MCP server in PolicyLayer and add a rule for chat.status: 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 Signomy. Nothing to install.
chat.status is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the chat.status 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.
Set action: deny in the PolicyLayer policy for chat.status. 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.
chat.status is provided by the Signomy MCP server (sunrisesillneversee/agent-universe). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
