List agents in the organization, optionally filtered by project.
AI agents call list_agents to retrieve information from Spaceship MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and lists existing agents with optional filtering. It performs no modifications, deletions, or external operations—it is a pure read operation that queries agent metadata. The blast radius of misuse is minimal; an agent could gain organizational visibility but cannot alter state or trigger execution.
From the tool's definition Tool name 'list_agents' and description 'List agents in the organization, optionally filtered by project' indicate a query/retrieval operation with no side effects.
Attacks that exploit this kind of access
List agents in the organization, optionally filtered by project. It is categorised as a Read tool in the Spaceship MCP MCP Server, which means it retrieves data without modifying state.
Register the Spaceship 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 Spaceship MCP. 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 Spaceship MCP server (spaceship-ai/spaceship-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
