MOST DANGEROUS TOOLS

High Risk

The most dangerous Sequential Thinking MCP Server tools

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

POLICY

How to control Sequential Thinking MCP Server

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

Rate limit write operations

{
  "apply_leave": {
    "limits": [
      {
        "counter": "apply_leave_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "get_leave_balance": {
    "limits": [
      {
        "counter": "get_leave_balance_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

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