search_memory_facts
AI agents call search_memory_facts to retrieve information from KnowledgeSmith MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Despite the empty description, the tool name strongly suggests a query or search operation that retrieves information from memory/fact storage without side effects. This aligns with the Read category (retrieve, query, search).
From the tool's definition Tool name 'search_memory_facts' indicates a search operation, and the sibling tools on this server include 'search_memory_nodes' which is clearly a Read-category tool. The verb 'search' denotes retrieval without modification.

search_memory_facts. It is categorised as a Read tool in the KnowledgeSmith MCP MCP Server, which means it retrieves data without modifying state.
Register the KnowledgeSmith MCP server in PolicyLayer and add a rule for search_memory_facts: 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 KnowledgeSmith MCP. Nothing to install.
search_memory_facts 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 search_memory_facts 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 search_memory_facts. 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.
search_memory_facts is provided by the KnowledgeSmith MCP server (leo7nel23/knowledgesmith-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
search_memory_facts is one line of KnowledgeSmith's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
