列出所有 Pipeline。支持按状态筛选，按创建时间倒序排列。
AI agents call list_pipelines to retrieve information from Agent-Comm-Hub without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a retrieval/query operation that lists existing pipeline data with filtering and sorting options. It has no side effects, does not modify or execute any pipelines, and does not delete any data. The blast radius of misuse is minimal—an agent could only discover pipeline information already accessible to the authenticated user.
From the tool's definition Tool name 'list_pipelines' and description indicating it lists all pipelines with filtering and sorting capabilities ('列出所有 Pipeline' = 'List all Pipelines'; supports state filtering, reverse chronological ordering).

Register the Agent-Comm-Hub MCP server in PolicyLayer and add a rule for list_pipelines: 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-Comm-Hub. Nothing to install.
list_pipelines 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_pipelines 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_pipelines. 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_pipelines is provided by the Agent-Comm-Hub MCP server (liuboacean/agent-comm-hub). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
