semantic_search
AI agents call semantic_search to retrieve information from CodeFlow MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Semantic search retrieves and queries data from a codebase without modifying, deleting, or executing code. It returns analysis results such as matching code segments or related functions. No side effects occur beyond information retrieval. This is a Read operation with low severity since misuse would only result in exposure of existing codebase information, not destructive changes or execution of arbitrary code.
From the tool's definition Tool name 'semantic_search' combined with server description stating it 'Enables AI assistants to analyze codebases through semantic search' and 'provides real-time code analysis'.
Attacks that exploit this kind of access
semantic_search. It is categorised as a Read tool in the CodeFlow MCP Server MCP Server, which means it retrieves data without modifying state.
Register the CodeFlow MCP Server 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 CodeFlow MCP Server. 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 CodeFlow MCP Server MCP server (mrorigo/code-flow-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
