mcp-registry

Petrol's private MCP registry for GitHub Enterprise Copilot MCP controls.

registry.json is the source of truth: a specification-compliant MCP Registry ServerListResponse listing the MCP servers approved for use inside Petrol. A small HTTP service (server.js) hosts that file over the MCP v0.1 registry API so GitHub Enterprise can consume it as an MCP Registry URL.

To update the registry, edit registry.json. See instructions.md.

What we set up (2026-07-10)

  • Added a zero-dependency Node.js service (server.js) that serves registry.json over the GitHub-required MCP v0.1 endpoints (/v0.1/servers, .../versions/latest, .../versions/{version}) with CORS. Added a Dockerfile and the deploy guide HOSTING.md.
  • Deployed it to Petrol's own Azure as an App Service (Linux, Node 22 LTS):
    • Resource group rg-petrol-mcp, app petrol-mcp-registry, region germanywestcentral, SKU B1.
    • Live URL: https://petrol-mcp-registry.azurewebsites.net
    • httpsOnly enabled (HTTP → HTTPS 301 redirect).
  • Wired it into GitHub Enterprise → AI Controls → MCP:
    • MCP servers in Copilot → Enabled everywhere
    • MCP Registry URL → https://petrol-mcp-registry.azurewebsites.net
    • Restrict MCP access to registry servers → Registry only (only the servers in this registry are allowed org-wide).

registry.json was not changed by any of this — it is served as-is.

MCP Registry URL

Set this in GitHub Enterprise Copilot settings (MCP Registry URL):

https://petrol-mcp-registry.azurewebsites.net

Use the service root — GitHub appends /v0.1/... automatically. Do not point GitHub at the raw registry.json file: the v0.1 API is path-based (/v0.1/servers, /versions/latest, ...), which a static file cannot serve.

Notes

  • listed ≠ auto-running. Appearing in the registry means a server is allowed and installable; each developer still needs the relevant runtime (docker/podman, npx/Node, Babashka) and any required secrets (e.g. ES_API_KEY, DATABASE_URI, SONARQUBE_TOKEN) on their machine to actually run it.
  • * calva-backseat-driver connects over a TCP socket (localhost:1664). The MCP registry spec has no native socket transport type; this entry carries name/metadata only — configure the socket connection in your local mcp.json.
  • com.petrol/gdm-mcp is internal; the internal registryType signals it is not downloadable from a public registry.
  • Servers pass their required secrets as environment variables at runtime (they are marked isSecret: true in registry.json and are not stored in the registry).
