Search pre-indexed bundles for symbols from popular libraries (React, Express, etc.). Returns symbol definitions from dependency bundles — useful for go-to-definition into node_modules/vendor. Install bundles via CLI:
AI agents call search_bundles 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.
The tool searches pre-indexed dependency bundles and returns symbol definitions (like go-to-definition functionality). This is a retrieval operation that does not modify state, execute code, or trigger external side effects. It falls clearly into the Read category with low severity since it only provides code intelligence without mutation or operational risk.
From the tool's definition Tool performs 'search' and 'returns symbol definitions' from pre-indexed bundles — a read-only query operation with no side effects. No create, modify, delete, or execute capability mentioned.
Documented attack patterns abuse exactly the kind of access search_bundles 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 search_bundles:
{
"version": "1",
"default": "deny",
"tools": {
"search_bundles": {}
}
}search_bundles is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Search pre-indexed bundles for symbols from popular libraries (React, Express, etc.). Returns symbol definitions from dependency bundles — useful for go-to-definition into node_modules/vendor. Install bundles via CLI:. 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 search_bundles: 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.
search_bundles 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 search_bundles 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 search_bundles. 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.
search_bundles 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.
