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

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

## Why set_config is rated Medium

This tool creates or modifies build configuration data reversibly. It does not delete data (Destructive), execute arbitrary code (Execute), or involve financial operations (Financial). While it affects kernel compilation parameters, the effects are limited to configuration state and are reversible—new builds can use different configs.

From the tool's own definition: "Tool name 'set_config' and server context indicate modifying kernel build configuration. Sibling tool 'android_set_config' on the same server confirms this pattern of configuration modification. Tool description is empty, limiting direct evidence."

## Use case

AI agents use set_config to create or update resources in Pypi:labmcp Alicat, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Pypi:labmcp Alicat environment.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Pypi:labmcp Alicat:

## For agents

This record is a snapshot. Live verdicts and the full registry:

- Check every server in your MCP config at once: `npx -y policylayer stack`
- Vet a server before you add it: install the mcp-precheck skill — `npx skills add https://policylayer.com` (skill text: https://policylayer.com/skill.md)
- Query the registry over MCP: endpoint `https://api.policylayer.com/mcp` — tools `check_mcp_server`, `check_mcp_stack`, `check_tool`, `search_registry`, `get_change_events`
