Git-based code ownership: who contributed most to specific files (git shortlog). Requires git. Use to identify who to ask about specific files. For symbol-level ownership use get_symbol_owners instead. Read-only. Returns JSON: [{ file, owners: [{ author, commits, percentage }] }].
AI agents call get_code_owners to retrieve information from Trace without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries git history to retrieve code ownership information based on commit statistics. It has no side effects, cannot modify or delete data, and does not execute code or perform financial operations. It is purely informational retrieval, making it a Read category tool with low severity.
From the tool's definition Tool description explicitly states 'Read-only' and 'git shortlog' which queries git history. Returns ownership metadata without modifying anything. Uses: 'get code owners', 'who contributed most', 'identify who to ask' — all retrieval operations.
Documented attack patterns abuse exactly the kind of access get_code_owners gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Trace, and nothing reaches the server without passing your rules. This is the rule we recommend for get_code_owners:
{
"version": "1",
"default": "deny",
"tools": {
"get_code_owners": {}
}
}get_code_owners is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Git-based code ownership: who contributed most to specific files (git shortlog). Requires git. Use to identify who to ask about specific files. For symbol-level ownership use get_symbol_owners instead. Read-only. Returns JSON: [{ file, owners: [{ author, commits, percentage }] }]. It is categorised as a Read tool in the Trace MCP Server, which means it retrieves data without modifying state.
Register the Trace MCP server in PolicyLayer and add a rule for get_code_owners: 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 Trace. Nothing to install.
get_code_owners 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 get_code_owners 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 get_code_owners. 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.
get_code_owners is provided by the Trace MCP server (nikolai-vysotskyi/trace-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
