Use when: you want high-level stats about the whole library — total counts of photos, movies, albums, folders, keywords, and persons — or to confirm which library you
AI agents call library-info to retrieve information from Apple Photos 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 aggregate statistics about the Apple Photos library without side effects. It is purely informational retrieval, making it a Read category tool. Low severity because the output is only summary metadata that any local user could already observe, with no ability to export sensitive photo content or modify the library.
From the tool's definition Tool retrieves 'high-level stats' and 'counts' of library metadata—total photos, movies, albums, folders, keywords, persons. Description explicitly states 'you want high-level stats' (read operation). No data modification, deletion, or execution occurs.
Attacks that exploit this kind of access
Use when: you want high-level stats about the whole library — total counts of photos, movies, albums, folders, keywords, and persons — or to confirm which library you. It is categorised as a Read tool in the Apple Photos MCP Server, which means it retrieves data without modifying state.
Register the Apple Photos MCP server in PolicyLayer and add a rule for library-info: 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 Apple Photos. Nothing to install.
library-info 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 library-info 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 library-info. 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.
library-info is provided by the Apple Photos MCP server (sweetrb/apple-photos-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
