Server tool list (4)
Raw names from tools/list. Only developers need these.
| check_mcp_endpoint | Probe an MCP endpoint right now: is it alive, which transport it speaks, how many tools it exposes, and whether its tool schema changed since the last check. Use before depending on a third-party MCP server. |
| get_uptime | Uptime history for an MCP endpoint over the last N days (max 30), with incident windows. Reads stored history; does not probe. |
| get_known_tools | The tool list last observed at an MCP endpoint, with the timestamp of the most recent schema change. Reads stored history; does not probe. |
| check_schema_drift | Probe an MCP endpoint and diff its tool schema against the last stored snapshot: tools added, removed, or whose description/inputSchema changed. Schema drift fails quietly mid-run, which is why it is worth checking. |
