Minecraft Server Management Protocol
- Added a server management API (JSON-RPC over WebSocket) for dedicated servers.
- The API is disabled by default and can be enabled in the server properties file.
management-server-enabled=truemanagement-server-host=localhostmanagement-server-port=25585
- The API is accessible at
ws://<management-server-host>:<management-server-port>when enabled. - Supports querying and updating of server state (players, allowlist, operators, settings, game rules).
- Sends notifications on state changes (e.g. player joins, game rule updates).
- Calling
{"id":1,"method":"rpc.discover"}returns an API schema containing supported methods and notifications of the currently running server. - The Data Generator produces an API schema (
json-rpc-api-schema.json) in the reports output folder mirroring the contents returned by therpc.discovermethod. - The API adheres to the JSON-RPC 2.0 specification.
- Uses namespaced methods and the reserved namespaces are
minecraft(e.g.minecraft:players,minecraft:allowlist/add) and notification (e.g.notification:players/joined).- Extensible via custom namespaces for additional methods and events.
- Core method groups: players, allowlist, operators, server (save, stop), server settings, game rules.
- Example method call:
- Request:
{"method":"minecraft:allowlist/add","id":1,"params":[[{"name":"jeb_"}]]} - Response:
{"jsonrpc":"2.0","id":1,"result":[{"id":"853c80ef-3c37-49fd-aa49-938b674adae6","name":"jeb_"}]}
- Request:
- Example notification:
{"jsonrpc":"2.0","method":"notification:players/joined","params":[{"id":"853c80ef-3c37-49fd-aa49-938b674adae6","name":"jeb_"}]}
- Example error:
- Request:
{"method": "minecraft:foo/bar","id": 1} - Response:
{"jsonrpc":"2.0","id":1,"result":{"jsonrpc":"2.0","id":1,"error":{"code":-32601,"message":"Method not found","data":"Method not found: minecraft:foo/bar"}}} - Errors and error codes follow JSON-RPC 2.0 error object format.
- Request:
- The API is disabled by default and can be enabled in the server properties file.
- Added "Allow Cursor Changes" option in "Mouse Settings" menu.
