Find all client calls across subprojects that call a specific endpoint. Shows file, line, call type, and confidence. Use to find all consumers of an endpoint before modifying it. Read-only. Returns JSON: { endpoint, clients: [{ repo, file, line, callType, confidence }], total }.
AI agents call get_subproject_clients 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 retrieves and queries dependency graph data to identify callers of a specific endpoint. It performs static analysis without modifying, executing, or deleting any code or data. The 'read-only' designation and query nature confirm this is a Read category tool with low severity risk.
From the tool's definition Tool description explicitly states 'Read-only' and 'Find all client calls across subprojects that call a specific endpoint. Shows file, line, call type, and confidence.' The return value is a static JSON analysis result with no side effects.
Documented attack patterns abuse exactly the kind of access get_subproject_clients 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_subproject_clients:
{
"version": "1",
"default": "deny",
"tools": {
"get_subproject_clients": {}
}
}get_subproject_clients is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Find all client calls across subprojects that call a specific endpoint. Shows file, line, call type, and confidence. Use to find all consumers of an endpoint before modifying it. Read-only. Returns JSON: { endpoint, clients: [{ repo, file, line, callType, confidence }], total }. 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_subproject_clients: 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_subproject_clients 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_subproject_clients 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_subproject_clients. 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_subproject_clients 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.
