3TG Test Generation

Q: How do I prevent bulk modifications through 3TG Test Generation?

The 3TG Test Generation server has 6 write tools including create_agent_instructions, create_mock_for_function, create_spec. Set a rate limit in your policy -- for example, 10 calls per hour prevents an agent from making more than 10 modifications per hour. PolicyLayer enforces this at the gateway, before calls reach 3TG Test Generation.

Q: How many tools does the 3TG Test Generation MCP server expose?

10 tools across 3 categories: Execute, Read, Write. 4 are read-only. 6 can modify, create, or delete data.

Q: How do I enforce a policy on 3TG Test Generation?

Register the 3TG Test Generation MCP server in PolicyLayer, apply the suggested rules above (adjust the limits to your use case), and point your AI client at the PolicyLayer proxy URL instead of the server directly. Your agents keep the same tools; PolicyLayer evaluates every call against policy before it executes. Nothing to install, live in minutes.

MOST DANGEROUS TOOLS

High Risk

The most dangerous 3TG Test Generation tools

Write · Low create_agent_instructions This tool creates or generates files—reversible write operations. Write · Medium create_mock_for_function This tool creates and writes a new file to the project's mock directory structure. Write · Low create_spec This is a Write operation: it creates a new spec file artifact that documents test requirements. Write · Low create_spec_for_function The tool creates or generates a specification document scoped to a function or component.

6 of 3TG Test Generation's 10 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control 3TG Test Generation

PolicyLayer is an MCP gateway — it sits between your AI agents and 3TG Test Generation, and nothing reaches the server without passing your rules. These are the rules we recommend:

Rate limit write operations

{
  "create_agent_instructions": {
    "limits": [
      {
        "counter": "create_agent_instructions_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "get_client_info": {
    "limits": [
      {
        "counter": "get_client_info_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

Controls API costs and prevents retry loops from exhausting upstream rate limits.
