AI agents call raw_versions to retrieve information from Agent Wiki without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns version information about files—a retrieval operation with no side effects. It does not create, modify, delete, or execute anything. The blast radius if misused by an AI agent is minimal: it only exposes file version metadata that is likely already internal to the system. Classification as Read is appropriate.
From the tool's definition Tool name 'raw_versions' and description 'List all versions of a raw file' indicate a read-only operation that retrieves version history metadata without modifying data.

Register the Agent Wiki MCP server in PolicyLayer and add a rule for raw_versions: 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 Agent Wiki. Nothing to install.
raw_versions 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 raw_versions 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 raw_versions. 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.
raw_versions is provided by the Agent Wiki MCP server (xinhuagu/agent-wiki). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
