WHAT IT DOES

What search_code does on Mcp Dev

AI agents call search_code to retrieve information from Mcp Dev without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why search_code is rated Low

This is a read-only operation that searches and retrieves code context. It does not create, modify, execute, delete, or move data. The semantic search functionality is non-destructive and returns information about the codebase without side effects. The context of being part of a development assistant system focused on 'codebase context' further supports this as an information retrieval tool.

From the tool's definition Tool name 'search_code' and description 'Semantic search over the current branch' indicate a query operation that retrieves codebase information without modifying, executing, or deleting data.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs search_code safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Mcp Dev, 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 Allowed

search_code is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "search_code": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Mcp Dev, apply this rule, and every search_code call is checked against it from then on.

FAQ

Questions about search_code

What does the search_code tool do? +

Semantic search over the current branch\. It is categorised as a Read tool in the Mcp Dev MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on search_code? +

Register the Mcp Dev 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 Mcp Dev. Nothing to install.

What risk level is search_code? +

search_code is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit search_code? +

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.

How do I block search_code completely? +

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.

What MCP server provides search_code? +

search_code is provided by the Mcp Dev MCP server (2loch-ness6/mempalace-mcp-dev). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
