/** |
| 3 |
* MCP tool registry — the single source of truth for the tools xSpeed |
| 4 |
* exposes to AI assistants. |
| 5 |
* |
| 6 |
* Each tool declares an MCP-style descriptor (name, description, JSON |
| 7 |
* Schema inputSchema) and a handler that runs against the Free engine. |
| 8 |
* Consumed by BOTH: |
| 9 |
* - Mcp_Server (the per-site JSON-RPC endpoint at /xspeed/mcp), and |
| 10 |
* - McpModule's REST tool routes (the optional hosted-broker path), |
| 11 |
* so the two transports can never drift. |
| 12 |
* |
| 13 |
* Handlers take an associative array of already-decoded arguments and |
| 14 |
* return either a plain array (serialized to JSON in the MCP result) or |
| 15 |
* a WP_Error (surfaced as an MCP tool error). |
| 16 |
* |
| 17 |
* The plugin adds ZERO cache logic here — every handler is a thin proxy |
| 18 |
* to Cache / Settings / Settings_Manager / Server / Admin / Pro_Audit / |
| 19 |
* Cache_Benchmark. |
| 20 |
