MOST DANGEROUS TOOLS

High Risk

The most dangerous MCP Server Proto-OKN tools

Execute · High query Given the server context (SPARQL endpoint querying) and the tool name 'query', this tool likely executes SPARQL queries against knowledge graph endpoints. Execute · High route_query The server is designed for querying SPARQL endpoints. Write · Low create_chat_transcript This tool creates or generates new data (a chat transcript) without irreversible consequences.

4 of MCP Server Proto-OKN's 13 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control MCP Server Proto-OKN

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

Rate limit write operations

{
  "create_chat_transcript": {
    "limits": [
      {
        "counter": "create_chat_transcript_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "get_descendants": {
    "limits": [
      {
        "counter": "get_descendants_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

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