recall

Semantic search over evidence_log rows. Embeds the query and every (title + body) pair, ranks by cosine similarity, returns the top-N matches with their scores. v1.1 first cut uses a deterministic signed-hash-bag embedder; a real local model will land in a follow-up behind the same async interface.

What recall does on Slopweaver

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

Why recall needs a policy

The recall tool is a pure retrieval and ranking operation. It searches and returns matching data without modifying, deleting, or executing any operations. The use of embedding and similarity ranking does not elevate this beyond a Read operation. The deterministic nature and local-first context confirm this is a passive data retrieval tool with minimal blast radius if misused.

From the tool's definition Tool performs "Semantic search over evidence_log rows" with "Embeds the query and every (title + body) pair, ranks by cosine similarity, returns the top-N matches". No mutations, deletions, or side effects described.

Questions about recall

What does the recall tool do? +

Semantic search over evidence_log rows. Embeds the query and every (title + body) pair, ranks by cosine similarity, returns the top-N matches with their scores. v1.1 first cut uses a deterministic signed-hash-bag embedder; a real local model will land in a follow-up behind the same async interface. It is categorised as a Read tool in the Slopweaver MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on recall? +

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

What risk level is recall? +

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

Can I rate-limit recall? +

Yes. Add a rate_limit block to the recall 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 recall completely? +

Set action: deny in the PolicyLayer policy for recall. 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 recall? +

recall is provided by the Slopweaver MCP server (slopweaver/slopweaver). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
