What search_code does on Code MCP Server
AI agents call search_code to retrieve information from Code MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why search_code is rated Low
This tool performs pattern matching and code search, which is a read-only operation that retrieves information without creating, modifying, deleting, or executing code. It has minimal blast radius if misused by an AI agent—worst case would be disclosure of existing code patterns or sensitive information already in the workspace, not data destruction or execution of harmful commands.
From the tool's definition Tool name is 'search_code' and description states 'Search for patterns in code' - these indicate a query/retrieval operation with no modifications or side effects.
Attacks that exploit this kind of access
The rule that runs search_code safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Code MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For search_code, this is the rule to start with:
search_code is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Code MCP Server, apply this rule, and every search_code call is checked against it from then on.
Questions about search_code
Search for patterns in code. It is categorised as a Read tool in the Code MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Code MCP Server MCP server in PolicyLayer and add a rule for search_code: 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 Code MCP Server. Nothing to install.
search_code 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 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. 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 is provided by the Code MCP Server MCP server (agentics-ai/code-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
