List and filter traces with sorting, pagination, and server-side filtering. A trace represents a complete workflow execution containing multiple spans (individual operations). IMPORTANT: Use the
AI agents call list_traces to retrieve information from Respan MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool performs a read-only operation that retrieves and filters existing trace data. It supports listing, filtering, sorting, and pagination—all standard data retrieval patterns with no side effects. No data is created, modified, deleted, or executed. This is a classic Read category tool.
From the tool's definition Tool name 'list_traces' and description 'List and filter traces with sorting, pagination, and server-side filtering' indicates a query/retrieval operation with no modification or execution capability.

List and filter traces with sorting, pagination, and server-side filtering. A trace represents a complete workflow execution containing multiple spans (individual operations). IMPORTANT: Use the. It is categorised as a Read tool in the Respan MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Respan MCP Server MCP server in PolicyLayer and add a rule for list_traces: 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 Respan MCP Server. Nothing to install.
list_traces 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 list_traces 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 list_traces. 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.
list_traces is provided by the Respan MCP Server MCP server (respanai/respan-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
