列出所有活跃的任务
AI agents call list_active_tasks to retrieve information from Claude Code Multi-Process MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns information about running tasks. It has no side effects, does not execute code, does not modify state, and does not delete anything. It is a straightforward read/list operation typical of monitoring or status-checking functionality in a task management system.
From the tool's definition Tool name 'list_active_tasks' and description '列出所有活跃的任务' (list all active tasks) indicate a retrieval operation that enumerates existing background tasks without modification.

列出所有活跃的任务. It is categorised as a Read tool in the Claude Code Multi-Process MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Claude Code Multi-Process MCP Server MCP server in PolicyLayer and add a rule for list_active_tasks: 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 Code Multi-Process MCP Server. Nothing to install.
list_active_tasks 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_active_tasks 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_active_tasks. 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_active_tasks is provided by the Claude Code Multi-Process MCP Server MCP server (l-x-c/cc-multi-process-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
list_active_tasks is one line of Claude Code Multi-Process MCP Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
