MOST DANGEROUS TOOLS

High Risk

The most dangerous Event Horizon MCP Server tools

Execute · Medium evolve_generation This tool executes a genetic algorithm operation (crossover analysis and generation evolution) which constitutes computational execution with side effects—it advances an evolutionary process state. Execute · High start_evolution This tool executes a complex algorithmic process (genetic algorithm simulation) whose outcomes and effects depend entirely on the arguments supplied (problem statement, evaluation criteria). Execute · Medium score_solution Score a solution against a specific consistency check. Use this tool to evaluate how well a solution performs against each consistency chec Write · Medium add_solution The tool creates or adds new data entries (solutions) to the evolutionary system in a reversible manner.

4 of Event Horizon MCP Server's 5 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control Event Horizon MCP Server

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

Rate limit write operations

{
  "add_solution": {
    "limits": [
      {
        "counter": "add_solution_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "get_evolution_status": {
    "limits": [
      {
        "counter": "get_evolution_status_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

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

Create a free account and register Event Horizon MCP Server — nothing to install.
Add these rules — paste them, or build them visually. Tune the limits to your setup.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about Event Horizon MCP Server

How do I prevent bulk modifications through Event Horizon MCP Server? +

The Event Horizon MCP Server server has 1 write tools including add_solution. 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 Event Horizon MCP Server.

How many tools does the Event Horizon MCP Server MCP server expose? +

5 tools across 3 categories: Execute, Read, Write. 1 are read-only. 4 can modify, create, or delete data.

How do I enforce a policy on Event Horizon MCP Server? +

Register the Event Horizon MCP Server 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.

Enforce policy on every Event Horizon MCP Server tool call.

Deterministic rules across all 5 Event Horizon MCP Server tools. Per-identity grants. Full audit log. Live in minutes. Nothing to install.
