    koyeb
    deploy to koyeb

    The form opens with CHANGE_ME for each value you supply: CITE_NEXUS_CONTACT_EMAIL, SEMANTIC_SCHOLAR_API_KEY, OPENALEX_API_KEY, SERPAPI_API_KEY, SCOPUS_API_KEY, SCOPUS_INSTTOKEN, WOS_API_KEY, UNPAYWALL_EMAIL. Fill them in before you deploy.

    Clients connect to the service's https://…koyeb.app address plus /mcp.

    azure
    deploy to azuretemplate

    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.
