Retrieves a specific document by its path relative to the Pydantic documentation root (e.g., 'usage/models.md').
AI agents call get_document_by_path 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 operation to fetch documentation content. It has no capability to modify, delete, or execute code. The blast radius is minimal as it only returns static documentation files. The severity is low because documentation retrieval poses no security risk to systems or data integrity.
From the tool's definition Tool description states it 'Retrieves a specific document' with 'no side effects' — it accesses documentation content by path parameter without modification or execution capabilities.

Retrieves a specific document by its path relative to the Pydantic documentation root (e.g., 'usage/models.md'). 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 get_document_by_path: 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.
get_document_by_path 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 get_document_by_path 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 get_document_by_path. 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.
get_document_by_path 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.
