# get_runtime_profile

Runtime profile for a symbol or route: call count, latency percentiles (p50/p95/p99), error rate, calls per hour. Requires OTLP trace ingestion. Read-only, queries external runtime data. Use for performance analysis of specific endpoints. Returns JSON: { symbol_id, callCount, latency: { p50, p95, p99 }, errorRate, callsPerHour }.

## Facts

- Tool: `get_runtime_profile`
- Server: Trace (`nikolai-vysotskyi/trace-mcp`) — https://policylayer.com/tools/nikolai-vysotskyi-trace-mcp.md
- Homepage: https://github.com/nikolai-vysotskyi/trace-mcp
- Risk category: Read (Low risk)
- Registry record: grade F, identity unverified
- Server rate-limited: no
- Parameters: 0
- Recommended policy verdict: Allowed

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "get_runtime_profile",
    "arguments": {}
  }
}
```

## Why get_runtime_profile is rated Low

This tool purely queries observability data (OTLP traces) and returns JSON performance statistics. It has no side effects, cannot modify code or systems, and poses no destruction or financial risk. The read-only designation and retrieval-only function clearly place it in the Read category.

From the tool's own definition: "'Read-only, queries external runtime data' and 'Runtime profile for a symbol or route: call count, latency percentiles (p50/p95/p99), error rate, calls per hour.' The tool retrieves performance metrics without modifying state."

## Use case

AI agents call get_runtime_profile 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.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Trace:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_runtime_profile": {}
  }
}
```
