## Facts

- Tool: `navigation_add_obstacle`
- Server: Godot (`chanceflow/godot-mcp`) — https://policylayer.com/tools/chanceflow-godot-mcp.md
- Homepage: https://github.com/ChanceFlow/godot-mcp
- Risk category: Write (Medium risk)
- Registry record: grade F, identity unverified
- Server rate-limited: no
- Parameters: 0
- Recommended policy verdict: Rate-limited

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "navigation_add_obstacle",
    "arguments": {}
  }
}
```

## Why navigation_add_obstacle is rated Medium

The 'add' verb combined with 'obstacle' in a Godot game engine context indicates the tool creates or inserts a new navigation obstacle entity into the game world, modifying scene state reversibly. This is a Write operation rather than Execute because it adds a discrete game object rather than running arbitrary code.

From the tool's own definition: "Tool name 'navigation_add_obstacle' indicates creation of a game engine object; 'add' prefix suggests a write/create operation that modifies the scene or navigation system. No description provided, limiting certainty."

## Use case

AI agents use navigation_add_obstacle to create or update resources in Godot, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Godot environment.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Godot:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "navigation_add_obstacle": {
      "limits": [
        {
          "counter": "navigation_add_obstacle_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}
```
