AI agents call list_tools to retrieve information from DocAgent without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only retrieves and displays information about available tools in the DocAgent server. It performs no data modifications, does not execute operations, and has no destructive or financial implications. The action is purely read-only information disclosure, making it the least risky classification.
From the tool's definition Tool name is 'list_tools' and description states 'List available tools' - this is a simple informational query that retrieves metadata about available functionality with no side effects.

Register the DocAgent MCP server in PolicyLayer and add a rule for list_tools: 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 DocAgent. Nothing to install.
list_tools 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_tools 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_tools. 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_tools is provided by the DocAgent MCP server (vinnyfds/docagent). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
