Lists all available changelog files found in the Pydantic-AI documentation repository (e.g., in 'docs/history/').
AI agents call list_available_changelogs 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 only a read operation: it retrieves and enumerates metadata about existing documentation artifacts. There is no creation, modification, deletion, code execution, or financial impact. The blast radius of misuse is minimal — an AI could at worst enumerate changelogs it shouldn't access, but cannot alter or destroy data.
From the tool's definition Tool 'list_available_changelogs' lists available changelog files without modifying any data. The description states it 'Lists all available changelog files' — a pure retrieval operation with no side effects.
Attacks that exploit this kind of access
Lists all available changelog files found in the Pydantic-AI documentation repository (e.g., in 'docs/history/'). 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_available_changelogs: 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_available_changelogs 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_available_changelogs 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_available_changelogs. 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_available_changelogs 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.
