Search for entities semantically using vector embeddings and similarity in your DevFlow MCP knowledge graph memory
AI agents call semantic_search to retrieve information from DevFlow MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries the knowledge graph and returns matching entities based on semantic similarity. It has no capability to modify, delete, or execute operations—only to retrieve data. The blast radius of misuse is minimal; an agent could retrieve unintended information but cannot alter the knowledge graph or trigger external actions.
From the tool's definition Tool name 'semantic_search' and description 'Search for entities semantically using vector embeddings and similarity' indicate a retrieval operation with no side effects.
Attacks that exploit this kind of access
Search for entities semantically using vector embeddings and similarity in your DevFlow MCP knowledge graph memory. It is categorised as a Read tool in the DevFlow MCP MCP Server, which means it retrieves data without modifying state.
Register the DevFlow MCP server in PolicyLayer and add a rule for semantic_search: 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 DevFlow MCP. Nothing to install.
semantic_search 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 semantic_search 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 semantic_search. 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.
semantic_search is provided by the DevFlow MCP server (takin-profit/devflow-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
