Lists files and directories non-recursively within the Pydantic documentation.
AI agents call list_topics to retrieve information from Pydantic AI Documentation Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only query of the documentation structure. It retrieves information about available topics but does not create, modify, delete, or execute anything. The blast radius is minimal—an agent misusing this tool could only access information about documentation organization, with no capability to alter state or trigger external operations.
From the tool's definition Tool description states it 'Lists files and directories non-recursively within the Pydantic documentation' — a pure retrieval operation with no side effects.
Attacks that exploit this kind of access
Lists files and directories non-recursively within the Pydantic documentation. It is categorised as a Read tool in the Pydantic AI Documentation Server MCP Server, which means it retrieves data without modifying state.
Register the Pydantic AI Documentation Server MCP server in PolicyLayer and add a rule for list_topics: 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 Pydantic AI Documentation Server. Nothing to install.
list_topics 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_topics 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_topics. 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_topics is provided by the Pydantic AI Documentation Server MCP server (omniwaifu/pydantic-ai-docs-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
