List all running and completed AI agent processes. Returns a simple list with PID, agent type, and status for each process.
AI agents call list_processes to retrieve information from Agent Bridge without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries process metadata without side effects. It performs status inspection only, matching the 'Read' category definition of retrieving data without causing side effects. The low severity reflects that process listing poses minimal risk even if misused by an agent, as it only exposes metadata about already-running processes rather than enabling new actions or data loss.
From the tool's definition Tool description explicitly states it 'List all running and completed AI agent processes' and 'Returns a simple list with PID, agent type, and status' — purely informational retrieval with no modification, deletion, or execution capabilities.
Attacks that exploit this kind of access
List all running and completed AI agent processes. Returns a simple list with PID, agent type, and status for each process. It is categorised as a Read tool in the Agent Bridge MCP Server, which means it retrieves data without modifying state.
Register the Agent Bridge MCP server in PolicyLayer and add a rule for list_processes: 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 Agent Bridge. Nothing to install.
list_processes 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_processes 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_processes. 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_processes is provided by the Agent Bridge MCP server (lailai258/agent-bridge-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
