Refresh the list of database paths
AI agents call refresh_databases to retrieve information from Phalcon MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool appears to refresh/reload a cached list of database paths, which is a read operation that queries available databases. No data is created, modified, or deleted. Confidence is moderate because the description is brief and 'refresh' could imply some side effects, but in context it likely just re-reads and updates an in-memory list.

Attacks that exploit this kind of access
Refresh the list of database paths. It is categorised as a Read tool in the Phalcon MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Phalcon MCP Server MCP server in PolicyLayer and add a rule for refresh_databases: 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 Phalcon MCP Server. Nothing to install.
refresh_databases 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 refresh_databases 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 refresh_databases. 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.
refresh_databases is provided by the Phalcon MCP Server MCP server (xindong888999/phalcon-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
