Browse indexed agents with their trust scores. Returns a paginated list of all known ACP agents.
AI agents call list_agents to retrieve information from Maiat Protocol without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a simple query/list operation that retrieves publicly indexed agent information. The blast radius of misuse is minimal — an AI agent could over-query or enumerate agents, but cannot modify trust scores, move funds, delete records, or trigger external actions. Categorized as Read with low severity.
From the tool's definition Tool description states it 'Browse[s] indexed agents' and 'Returns a paginated list of all known ACP agents' — these are read-only retrieval operations with no data modification, creation, deletion, or side effects.
Attacks that exploit this kind of access
Browse indexed agents with their trust scores. Returns a paginated list of all known ACP agents. It is categorised as a Read tool in the Maiat Protocol MCP Server, which means it retrieves data without modifying state.
Register the Maiat Protocol MCP server in PolicyLayer and add a rule for list_agents: 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 Maiat Protocol. Nothing to install.
list_agents 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 list_agents 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 list_agents. 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.
list_agents is provided by the Maiat Protocol MCP server (jhinresh/maiat-protocol). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Every MCP server has a record like this.
