simsima-connectivity — MCP server

Glama score

Website: simsima.io · Endpoint: POST https://mcp.simsima.io/mcp (Streamable HTTP) · Registry: io.github.Willyfab/simsima-connectivity

Public MCP server exposing Simsima's travel eSIM catalog to AI agents. Endpoint: POST https://mcp.simsima.io/mcp (Streamable HTTP). Health: GET /health.

Tools

  • list_destinations — countries/regions covered, with min price + product URL.
  • search_plans — plans for a destination, with optional price/data/validity filters.
  • get_plan — a single plan by sku.
  • recommend_plan — best plan(s) for a trip (length + light/medium/heavy usage).
  • create_checkout_link — a Simsima product URL with agent attribution (source/utm_*).

Read + attributed-link only. No payment, no order data, no auth.

Data source

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 in en/fr (regional/global inherit from the feed later).

Env

  • SIMSIMA_FEED_BASE (default https://simsima.io)
  • PORT (default 8080)
  • RATE_LIMIT_RPM (default 60)
  • POSTHOG_KEY (optional) — PostHog project API key. When set, the server emits an mcp_tool_call event per tool call. Absent → telemetry disabled (no-op).
  • POSTHOG_HOST (optional, default https://us.i.posthog.com) — PostHog ingestion host (match the web app).

Local dev

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 at https://mcp.simsima.io/mcp, then try: "Recommande-moi un eSIM pour 7 jours au Japon en usage moyen."

Deploy

Coolify app, Docker build context = mcp/, subdomain mcp.simsima.io. Auto-deploy on push to main. Set SIMSIMA_FEED_BASE, PORT, RATE_LIMIT_RPM env vars.

Publication to the MCP Registry (Phase 1b)

Metadata lives in server.json (namespace io.github.Willyfab/simsima-connectivity, remote streamable-http at https://mcp.simsima.io/mcp). Discovery is also hinted from web/public/llms.txt + llms-full.txt.

To publish (needs the mcp-publisher CLI + 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
  • Bump version in server.json on each meaningful change and re-run publish.
  • To use a branded com.simsima/connectivity namespace instead, verify domain ownership of simsima.io via a DNS TXT record, then update name in server.json (the remote URL mcp.simsima.io already sits on the verified domain).
