search_code_semantic
AI agents call search_code_semantic to retrieve information from Portable MCP Toolkit without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool performs semantic search across a codebase using vector search, which is a read-only query operation. No side effects are created—it retrieves information only. The empty description slightly reduces confidence, but the server's stated purpose and related tools strongly indicate this is a search/retrieval function, placing it firmly in the Read category with low severity.
From the tool's definition Tool name 'search_code_semantic' indicates semantic search functionality. Server description emphasizes 'semantic code search' and 'context-optimized code generation' as core features.
Attacks that exploit this kind of access
search_code_semantic. It is categorised as a Read tool in the Portable MCP Toolkit MCP Server, which means it retrieves data without modifying state.
Register the Portable MCP Toolkit MCP server in PolicyLayer and add a rule for search_code_semantic: 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 Portable MCP Toolkit. Nothing to install.
search_code_semantic 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_code_semantic 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_code_semantic. 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_code_semantic is provided by the Portable MCP Toolkit MCP server (mjdevaccount/aistack-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
