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

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

## Why switch_ship is rated Medium

This tool modifies game state reversibly by switching the active ship and relocating cargo. It creates a new game state (different active ship, cargo in storage) but these changes can be undone by switching back. This is a Write operation rather than Destructive because the action is reversible and no data is permanently lost.

From the tool's own definition: "Swap your active ship with one stored at this station. Cargo from your current ship is moved to station storage. Modules stay on their ships."

## Use case

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

## Recommended policy (PolicyLayer)

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