one click: the provider's deploy form opens filled in, in your own account- koyeb
-
The form opens with CHANGE_ME for each value you supply: SOCRATA_APP_TOKEN, SOCRATA_DEFAULT_DOMAIN, SOCRATA_DATAFRAME_DROP_ENABLED, MCP_LOG_LEVEL. Fill them in before you deploy.
Clients connect to the service's https://…koyeb.app address plus /mcp.

A Container Apps environment with one app per server, each with HTTPS ingress and one replica. The portal asks for each value you supply as a secure parameter; the deployment's outputs list the endpoints.

Claude Code shows them as `mcp__socrata__<tool>`. - No credentials. ## Tools 6 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.
