AI agents call immich_ping to retrieve information from Immich without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a diagnostic/health-check tool that queries server status and version information. It retrieves data without side effects, matching the 'Read' category definition. Severity is low because the blast radius of misuse is minimal—an agent could only learn about server version and connectivity status, which are typically non-sensitive operational details.
From the tool's definition Tool description states it 'Verify connectivity and authentication' and 'Returns server version and status' — purely informational operations with no data modification or command execution.

Verify connectivity and authentication with the Immich server. Returns server version and status. It is categorised as a Read tool in the Immich MCP Server, which means it retrieves data without modifying state.
Register the Immich MCP server in PolicyLayer and add a rule for immich_ping: 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 Immich. Nothing to install.
immich_ping 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 immich_ping 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 immich_ping. 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.
immich_ping is provided by the Immich MCP server (whitehara/immich-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
