What search does on Rewind

AI agents call search to retrieve information from Rewind without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Why search needs a policy

This tool performs search and retrieval operations across personal data domains (listening, running, watching, collecting, reading). It uses FTS5 full-text search and semantic embeddings to query and return information, but does not modify, delete, or execute external actions. The primary function is data retrieval, making it a Read operation.

From the tool's definition Tool description states 'Search across all domains' with 'full-text search' and 'embeddings for...recall' — retrieval operations with no side effects.

Questions about search

What does the search tool do? +

Search across all domains (listening, running, watching, collecting, reading). Three ranking modes: keyword (default) uses FTS5 full-text search across all domains; semantic uses Voyage AI embeddings for paraphrased / meaning-based recall (reading domain only); hybrid fuses both (reading domain only). Use semantic or hybrid when the user describes what an article was ABOUT rather than quoting its words. Prefer. It is categorised as a Read tool in the Rewind MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on search? +

Register the Rewind MCP server in PolicyLayer and add a rule for search: 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 Rewind. Nothing to install.

What risk level is search? +

search is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit search? +

Yes. Add a rate_limit block to the search 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.

How do I block search completely? +

Set action: deny in the PolicyLayer policy for search. 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.

What MCP server provides search? +

search is provided by the Rewind MCP server (rewind-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
