Teleport Google Maps MCP — read-only, P2P, zero cloud

The official Google Maps server needs a billable API key. Share the capability instead of the credential: a remote agent geocodes and plans routes through your tunnel with a --max-calls ceiling so the bill stays boring. This guide maps all 7 tools of @modelcontextprotocol/server-google-maps by blast radius, then gives you the exact command to share it with a remote teammate's AI agent — capability without credentials.

host terminal — read-only share command

npx -y mcpwire share --allow "maps_geocode,maps_reverse_geocode,maps_search_places,maps_place_details,maps_directions,maps_distance_matrix,maps_elevation" --redact-secrets --ttl 30m -- npx -y @modelcontextprotocol/server-google-maps

Only the 7 read-only tools are exposed; the other 0 are invisible to the peer (filtered from tools/list and blocked if forced). Tunnel dies in 30 minutes. Add --confirm to approve every call, or --max-calls 20 for a hard budget.

peer config — claude_desktop_config.json / .cursor/mcp.json

🛡️ tool risk map — Google Maps

tool	risk	notes
`maps_geocode`	SAFE	Address to coordinates.
`maps_reverse_geocode`	SAFE	Coordinates to address.
`maps_search_places`	SAFE	POI search.
`maps_place_details`	SAFE	Place metadata.
`maps_directions`	SAFE	Routing.
`maps_distance_matrix`	SAFE	Distance/time matrix.
`maps_elevation`	SAFE	Elevation lookup.

🔒 Why not just share your token?

Google Maps's credential would grant the full toolset to a foreign LLM — including every mutating tool. With mcpwire the credential stays in your env; the peer only ever holds an expiring wire:// capability scoped to 7 tools.

🎥 Audit everything

Add --record session.wirelog and every call, block and redaction is logged locally. Drag the file into mcpwire.co/replay for a DevTools-style waterfall of what the remote agent actually did.

🔁 Works with every MCP client

Claude Desktop, Cursor, Windsurf, Cline — anything speaking MCP over stdio. Your peer pastes the snippet above; you keep the kill-switch (Ctrl+C) in your terminal.

What happens if the peer's agent tries to call a blocked Google Maps tool?

The request never reaches your MCP server. mcpwire answers with a JSON-RPC error (-32601 [MCPWire Firewall]) and logs the attempt — the tool doesn't exist from the agent's point of view, so well-behaved agents won't even try.

Can I expose the caution-level tools too?

Yes — just add them to --allow or run with --confirm so each call waits for your y/n in the host terminal. The risk map above tells you exactly what you'd be signing up for.

Is the traffic really serverless?

Yes. Discovery goes through the public Hyperswarm DHT; the data path is a direct Noise-encrypted socket between the two machines (UDP hole punching). If both NATs are stubborn, Hyperswarm routes through community relays — which only see ciphertext.
