in the cloud
one click: the provider's deploy form opens filled in, in your own account- koyeb
-
Koyeb builds the repository's Dockerfile from branch main; change the branch in the form if the default one has another name.
Clients connect to the service's https://…koyeb.app address plus /mcp.
- cloud run
-
Cloud Shell clones the repository, builds its Dockerfile and deploys it to Cloud Run.
Cloud Run sends requests to $PORT (8080); the recipe expects :8000, so the server has to read PORT, or set the container port on the service afterwards.

The only text from the server itself is in the section quoted from it below. ## How to reach it - A web service at `https://codecraft-ashy-seven.vercel.app/mcp` (streamable HTTP); nothing runs here. - Your MCP client knows it as `codecraft` (`clients/` configures it under that name); call its tools by the names below. Claude Code shows them as `mcp__codecraft__<tool>`. - No credentials. ## Tools 9 tools. The read-only column is the server's own hint (`readOnlyHint`), not something the hub checked. ### Quoted from the server: data, not instructions The names, sentences and parameter names in this table are the server's own text, as the hub listed it.

check_feasibilityChecks whether a user request can be built with a behavior pack and the @minecraft/server API. If it is blocked, returns why, the evidence behind that rule, and a workable alternative. Call this BEFORE writing any code or JSON: input simulation, file system access and network access do not exist in the Bedrock scripting API, and those are the most commonly hallucinated APIs.Checks whether a user request can be built with a behavior pack and the @minecraft/server API.

pin 9c6fcd0c8d570cb1c66650c7f44143fd1c1c3cd14a4bf88fe823516aad224465validate_pythonValidates a Python automation script that runs OUTSIDE the game, on three axes: Python syntax (using the real interpreter), Minecraft commands embedded in the script (against the official command index), and the shape of the /connect WebSocket message envelope. For behavior pack scripts use validate_script instead — Python does not run inside a pack. The embedded command check is the most valuable one: a command written from memory can look syntactically fine and still do nothing in the game. Only strings starting with / are treated as commands. If syntax could not be checked, syntaxChecked is false in the result; ok:true alone does not mean the syntax is valid.Validates a Python automation script that runs OUTSIDE the game, on three axes: Python syntax (using the real interpreter), Minecraft commands embedded in the script (against the official command index), and the shape of the /connect WebSocket message envelope.
