Reads the public web feed${SIMSIMA_FEED_BASE}/{locale}/agent/catalog(cached ~15 min). Product URLs come straight from the feed → always valid (zero 404). No database, no backend calls. Phase 1 covers country plans inen/fr(regional/global inherit from the feed later).
- SIMSIMA_FEED_BASE(defaulthttps://simsima.io)
- PORT(default 8080)
- RATE_LIMIT_RPM(default 60)
- POSTHOG_KEY(optional) — PostHog project API key. When set, the server emits anmcp_tool_callevent per tool call. Absent → telemetry disabled (no-op).
- POSTHOG_HOST(optional, defaulthttps://us.i.posthog.com) — PostHog ingestion host (match the web app).
cd mcp npm install npm test # jest (25 tests) npm run dev # ts-node-dev on :8080 curl localhost:8080/health
Connect from Claude (private validation — Phase 1a)
Add a custom connector pointing athttps://mcp.simsima.io/mcp, then try: "Recommande-moi un eSIM pour 7 jours au Japon en usage moyen."
Coolify app, Docker build context =mcp/, subdomainmcp.simsima.io. Auto-deploy on push tomain. SetSIMSIMA_FEED_BASE,PORT,RATE_LIMIT_RPMenv vars.
Publication to the MCP Registry (Phase 1b)
To publish (needs themcp-publisherCLI + GitHub auth as the repo owner):
cd mcp # install: see github.com/modelcontextprotocol/registry (release binary or go install) mcp-publisher login github # OIDC auth for the io.github.Willyfab/ namespace mcp-publisher publish # validates server.json and publishes
- Bumpversioninserver.jsonon each meaningful change and re-runpublish.
- To use a brandedcom.simsima/connectivitynamespace instead, verify domain ownership ofsimsima.iovia a DNS TXT record, then updatenameinserver.json(the remote URLmcp.simsima.ioalready sits on the verified domain).
