AI agents call project_doc_list_tags to retrieve information from ProjectDoc without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata about existing tags without creating, modifying, or deleting any data. It is a read-only query operation with minimal blast radius if misused by an AI agent—worst case would be retrieving tag information already accessible within the project scope.
From the tool's definition Tool name 'project_doc_list_tags' and description '列出所有标签' (list all tags) indicates a retrieval/query operation with no side effects. The description states it informs AI of available tags in the current project.

Register the ProjectDoc MCP server in PolicyLayer and add a rule for project_doc_list_tags: 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 ProjectDoc. Nothing to install.
project_doc_list_tags 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 project_doc_list_tags 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 project_doc_list_tags. 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.
project_doc_list_tags is provided by the ProjectDoc MCP server (yarrow-cai/project-doc). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
