Show which business domains depend on which. Based on edges between symbols in different domains. Use to understand domain coupling. Read-only. Returns JSON: { dependencies: [{ from, to, edgeCount }] }.
AI agents call get_cross_domain_deps 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 analyzes cross-domain dependency information from an already-built dependency graph. It performs analysis and navigation only, with no ability to modify code, execute operations, delete data, or commit financial transactions. The explicit 'Read-only' designation and JSON return structure confirm it is a passive inspection tool.
From the tool's definition Tool description explicitly states 'Read-only' and describes retrieval of dependency information: 'Show which business domains depend on which... Returns JSON'. The operation is a query that analyzes existing code structure without modification.
Documented attack patterns abuse exactly the kind of access get_cross_domain_deps 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_cross_domain_deps:
{
"version": "1",
"default": "deny",
"tools": {
"get_cross_domain_deps": {}
}
}get_cross_domain_deps is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Show which business domains depend on which. Based on edges between symbols in different domains. Use to understand domain coupling. Read-only. Returns JSON: { dependencies: [{ from, to, edgeCount }] }. 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_cross_domain_deps: 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_cross_domain_deps 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_cross_domain_deps 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_cross_domain_deps. 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_cross_domain_deps 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.
