Force re-scan of all Verse digest files for updated schema intelligence.
AI agents call verse_refresh_schemas to retrieve information from Uefn without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool reads/scans Verse digest files to refresh schema information. It is a read/index operation with no data modification, deletion, or execution of user code. The word 'Force' implies it triggers a scan immediately rather than waiting, but the action itself is non-destructive and only updates an internal schema cache.

Documented attack patterns abuse exactly the kind of access verse_refresh_schemas gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Uefn, and nothing reaches the server without passing your rules. This is the rule we recommend for verse_refresh_schemas:
{
"version": "1",
"default": "deny",
"tools": {
"verse_refresh_schemas": {}
}
}verse_refresh_schemas is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Force re-scan of all Verse digest files for updated schema intelligence. It is categorised as a Read tool in the Uefn MCP Server, which means it retrieves data without modifying state.
Register the Uefn MCP server in PolicyLayer and add a rule for verse_refresh_schemas: 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 Uefn. Nothing to install.
verse_refresh_schemas 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 verse_refresh_schemas 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 verse_refresh_schemas. 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.
verse_refresh_schemas is provided by the Uefn MCP server (quangdang46/uefn-verse-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Uefn, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
