## Facts

- Tool: `executeApi`
- Server: Dynamic API Server (MCP) (`1049861657/mcp`) — https://policylayer.com/tools/1049861657-mcp.md
- Homepage: https://github.com/1049861657/MCP
- Risk category: Execute (High risk)
- Registry record: grade C, identity unverified
- Server rate-limited: no
- Parameters: 0
- Recommended policy verdict: Rate-limited

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

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

## Why executeApi is rated High

This tool triggers external API operations whose effects depend entirely on which apiId is specified and what params are passed. While not inherently destructive, the execution of arbitrary APIs with dynamic parameters creates significant blast radius for misuse (could trigger financial transactions, data modifications, deletions, or other side effects depending on available APIs).

From the tool's own definition: "Tool name is 'executeApi' and description states 'Run apiId with params', indicating execution of arbitrary APIs with user-supplied parameters."

## Use case

AI agents invoke executeApi to trigger actions in Dynamic API Server (MCP). What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

## Recommended policy (PolicyLayer)

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

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "executeApi": {
      "limits": [
        {
          "counter": "executeapi_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}
```

## 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`
