Search for nodes in the knowledge graph based on a query
AI agents call mcp_memory_search_nodes to retrieve information from Chicken Business Management MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information from a knowledge graph without modifying, executing external operations, or destroying data. It performs a search query operation, which is a classic read action. The blast radius of misuse is limited to unauthorized data disclosure from the knowledge graph, not operational damage or financial impact.

Register the Chicken Business Management MCP Server MCP server in PolicyLayer and add a rule for mcp_memory_search_nodes: 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 Chicken Business Management MCP Server. Nothing to install.
mcp_memory_search_nodes 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 mcp_memory_search_nodes 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 mcp_memory_search_nodes. 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.
mcp_memory_search_nodes is provided by the Chicken Business Management MCP Server MCP server (psyger02/mcpserver). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
