Composite tool: gather everything known about a person + their gift history (to avoid repeating) + any past gift ideas tracked, so the LLM can suggest a thoughtful gift.
AI agents call gift_suggester to retrieve information from Personal Brain without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a composite Read tool that aggregates personal data (person profile, gift history, tracked ideas) to enable gift suggestion by the LLM. It performs only semantic queries and data retrieval across the personal database with no side effects, reversible writes, code execution, deletions, or financial transactions.
From the tool's definition Tool description states it 'gather[s] everything known about a person' and retrieves 'gift history' and 'past gift ideas tracked' — all retrieval operations with no modification, creation, deletion, or execution of external actions.

Composite tool: gather everything known about a person + their gift history (to avoid repeating) + any past gift ideas tracked, so the LLM can suggest a thoughtful gift. It is categorised as a Read tool in the Personal Brain MCP Server, which means it retrieves data without modifying state.
Register the Personal Brain MCP server in PolicyLayer and add a rule for gift_suggester: 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 Personal Brain. Nothing to install.
gift_suggester 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 gift_suggester 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 gift_suggester. 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.
gift_suggester is provided by the Personal Brain MCP server (phantomts/personal-brain-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
