recall · Manasdb MCP: Risk & Policy

WHAT IT DOES

What recall does on Manasdb

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

WHY IT NEEDS A POLICY

Why recall needs a policy

The recall tool performs a read/query operation against stored memories, returning deduplicated results across providers. It does not create, modify, delete, or trigger any external operations. This is a pure retrieval function.

From the tool's definition 'Recall related context from ManasDB memory' and 'retrieve' in server description; the tool retrieves/queries stored memories using semantic vector search with no side effects

Questions about recall

What does the recall tool do? +

Recall related context from ManasDB memory (deduplicated across configured providers). It is categorised as a Read tool in the Manasdb MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on recall? +

Register the Manasdb 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 Manasdb. 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 Manasdb MCP server (manasdb/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
