get_entity_edge
AI agents call get_entity_edge 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.
The tool appears to retrieve entity edge relationships from a knowledge graph or memory structure without modifying data. No destructive, financial, or code execution capabilities are implied. The empty description lowers confidence slightly, but the naming convention and server context strongly suggest this is a data retrieval (Read) operation with minimal risk.
From the tool's definition Tool name 'get_entity_edge' and the context of sibling tools (search_memory_facts, search_memory_nodes, get_episodes) indicate a query/retrieval operation.
Attacks that exploit this kind of access
get_entity_edge. 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 get_entity_edge: 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.
get_entity_edge 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 get_entity_edge 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 get_entity_edge. 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.
get_entity_edge 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.
