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://trust-gate-mcp.onrender.com/mcp` (streamable HTTP); nothing runs here. - Your MCP client knows it as `trust-gate` (`clients/` configures it under that name); call its tools by the names below. Claude Code shows them as `mcp__trust-gate__<tool>`. - No credentials. ## Tools 7 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.
