What get_subproject_clients does on Trace
AI agents call get_subproject_clients to retrieve information from Trace without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why get_subproject_clients is rated Low
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.
Attacks that exploit this kind of access
The rule that runs get_subproject_clients safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Trace, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For get_subproject_clients, this is the rule to start with:
get_subproject_clients 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 Trace, apply this rule, and every get_subproject_clients call is checked against it from then on.
Questions about get_subproject_clients

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.
