-"""Google Maps MCP server (JSON-RPC 2.0 over stdio).
-
-Capabilities (callable as `mcp__gmaps__<tool>`):
-  directions       — transit/driving/walking directions from A to B
-  geocode          — convert an address or place name to coordinates
-  reverse_geocode  — convert coordinates to an address
-  search_places    — find nearby places (stations, stops, POIs)
-  distance_matrix  — travel time & distance between multiple origins/destinations
-
-Auth:
-  API key is read from env var GOOGLE_MAPS_API_KEY, or from the file at
-  GOOGLE_MAPS_API_KEY_FILE (default: ./secrets/gmaps_api_key.txt).
-
-Required Google Cloud APIs to enable:
-  - Directions API
-  - Geocoding API
-  - Places API (New) or Places API
-  - Distance Matrix API

-"""
-MCP Server for Google Trends data via trendspyg.
-
-Provides tools to query Google Trends: interest over time, related queries,
-interest by region, trending now (RSS), and bulk trending CSVs.
-
-Uses trendspyg v0.7.0 as the data backend.
-Browser-based tools require Chrome installed on the host.
-RSS-based tools require no browser and return in ~0.2s.
-
-Rate limits: Google Trends is a public service. Browser-based queries should
-be spaced 5-10 seconds apart to avoid HTTP 429. RSS is lighter but still
-subject to rate limiting on excessive polling.
-
-Transport: stdio JSON-RPC (mcp.run() default). All diagnostics go to stderr —
-never stdout — to avoid corrupting the protocol stream.
-
-Output: tools return plain dicts, so FastMCP emits real ``structuredContent``
-(a JSON object) plus a pretty-printed text fallback. Errors are raised as
-``ToolError`` → the client receives an ``isError`` result carrying an
-LLM-actionable hint.

-                            through SerpAPI, returning prices, airlines, durations,
-                            layovers, and CO2 emissions.
-
-Auth:
-  API key is read from env var SERPAPI_API_KEY, or from the file at
-  SERPAPI_API_KEY_FILE (default: ./secrets/serpapi_api_key.txt).
-
-Run with:
-  python3 scripts/mcp/serpapi_flights/server.py

-/**
- * WhatsApp MCP Server (JSON-RPC 2.0 over stdio) — Baileys edition.
- *
- * Runs INSIDE the user's per-user container (blueprint §6/§7). Unlike the old
- * whatsapp-web.js server, this one uses `@whiskeysockets/baileys`: a pure-WebSocket
- * WhatsApp multi-device client with **no browser** — so it fits the slim
- * `skald-runtime` image (node, no Chromium) and needs no puppeteer self-healing.
- *
- * ── Interactive login contract (the generic §15 seam) ───────────────────────────
- * A per-user connector that needs an interactive login exposes ONE standard tool,
- * `login_status`, that Skald's login API calls directly (never the agent). It
- * returns a small JSON object the login panel renders:
- *
- *   { "state": "connecting" | "need_scan" | "ready" | "logged_out",
- *     "qr":    "data:image/png;base64,…"   // present only while state == need_scan
- *     "message": "human-readable line" }
- *
- * The panel polls it; when `state == "ready"` Skald flips the connector's
- * `auth_state` to `ready`. WhatsApp's credential is the persisted session on disk
- * (`./auth/`, under the bind-mounted home → survives a container recreate), not a
- * token — so there is nothing to paste back, only a QR to scan.
