WHAT IT DOES

What dive_code_locate does on Nodebench

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

RISK

Why dive_code_locate is rated Low

This tool performs static code searching and location mapping. While it stores results in a database, the operations are informational queries (grep searches) and reference data storage, with no side effects on the codebase, no code execution, and no destructive actions.

From the tool's definition Tool description states it 'uses grep/ripgrep to search the project codebase' and 'finds the exact source code location' - these are read-only search and query operations that retrieve information without modifying or executing code.

RECOMMENDED RULE

The rule that runs dive_code_locate safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Nodebench, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For dive_code_locate, this is the rule to start with:

dive_code_locate Allowed

dive_code_locate 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": {
    "dive_code_locate": {}
  }
}

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

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

FAQ

Questions about dive_code_locate

What does the dive_code_locate tool do? +

Find the exact source code location for a bug, component, or design issue. Uses grep/ripgrep to search the project codebase for the relevant code. Maps UI bugs to file:line so you know exactly where to fix. Stores the location in the DB linked to the bug/component for the full traceability chain: UI element → bug → source file:line → fix → verify. It is categorised as a Read tool in the Nodebench MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on dive_code_locate? +

Register the Nodebench MCP server in PolicyLayer and add a rule for dive_code_locate: 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 Nodebench. Nothing to install.

What risk level is dive_code_locate? +

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

Can I rate-limit dive_code_locate? +

Yes. Add a rate_limit block to the dive_code_locate 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 dive_code_locate completely? +

Set action: deny in the PolicyLayer policy for dive_code_locate. 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 dive_code_locate? +

dive_code_locate is provided by the Nodebench MCP server (nodebench-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
