MOST DANGEROUS TOOLS

High Risk

The most dangerous Bruno MCP Server tools

Write · Medium add_test_script This tool adds scripts to Bruno API requests, which modifies existing request configurations. Write · Medium create_collection This tool creates a new resource (a Bruno collection) which is a Write operation. Write · Medium create_crud_requests This tool generates request definitions within Bruno's API testing framework, which are reversible configurations that can be modified or deleted. Write · Medium create_environment This tool creates environment configuration files, which is a reversible write operation.

6 of Bruno MCP Server's 8 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control Bruno MCP Server

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

Rate limit write operations

{
  "add_test_script": {
    "limits": [
      {
        "counter": "add_test_script_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "get_collection_stats": {
    "limits": [
      {
        "counter": "get_collection_stats_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

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