Google Address Validation

@Google Address Validation check if '1600 Amphitheatre Pkwy, Mountain View CA' is deliverable and get its standardized format

The address validates successfully. Standardized format: '1600 Amphitheatre Parkway, Mountain View, CA 94043, USA'. Geocode: 37.4224764, -122.0842499. Deliverability verdict: DELIVERABLE with high confidence. Address components parsed: street number (1600), route (Amphitheatre Parkway), locality (Mountain View), administrative area (California), postal code (94043). USPS data confirms this is a valid delivery point.

This example shows the MCP's core validation capability — parsing user input into standardized components, geocoding, and returning a deliverability verdict. Requires a Google Cloud API key with Address Validation API enabled. Useful for checkout flows or CRM data cleanup where you need to confirm an address before storing it.

@Google Address Validation verify this international address: 'Buckingham Palace, London SW1A 1AA, United Kingdom' and tell me if it's residential or commercial

Address validates with modifications. Standardized: 'Buckingham Palace, Westminster, London SW1A 1AA, UK'. Geocode: 51.5013673, -0.1440787. Deliverability: DELIVERABLE. Address type: Premise (specific building). The API does not explicitly classify residential vs. commercial, but metadata indicates this is a landmark premise. Components include thoroughfare (unspecified), locality (Westminster), postal code (SW1A 1AA), country (United Kingdom).

Demonstrates international address handling and the MCP's parsing granularity. The API returns address type metadata (premise, subpremise, route) but does not directly label 'residential' or 'commercial' — that inference requires additional context. Works globally but coverage and detail vary by country. Check Google's supported territories list before relying on this for non-US addresses.

@Google Address Validation I just validated '123 Main St, Springfield' and got a suggestion to add 'IL 62701'. Confirm I used that corrected version in my system.

Feedback recorded. Your validation sequence ID has been logged with the outcome: VALIDATION_ACCEPTED. This helps Google improve address suggestions for ambiguous inputs like 'Springfield' (which exists in 30+ US states). No further action required on your end. The feedback tool does not return confirmation of what you stored — it only signals to Google that their suggestion was useful.

This example highlights the feedback loop tool, which is optional but improves Google's model over time. Use it after a validation attempt where the user accepted a suggested correction. Does not verify your database state — it's purely telemetry for Google. Requires the validation response ID from the prior Validate Address call. Consider calling this in background after checkout completion to avoid blocking user flows.

When this MCP saves shipping costs at checkout

A 6-person e-commerce team shipping 200+ orders daily uses this MCP to validate customer addresses before printing labels. The Validate Address tool catches typos, apartment numbers in the wrong field, and undeliverable PO boxes in real-time during checkout. The geocode output flags addresses outside their shipping zones before the order hits fulfillment. The trade-off: Google charges per validation call, so teams under 50 orders/day might not justify the API cost versus manual review. If your return rate from bad addresses is above 3%, this MCP pays for itself in the first month. Wire it into your checkout flow with the API key and start catching errors before they ship.

When geocode accuracy matters for same-day dispatch

A 12-person HVAC company running same-day service calls uses this MCP to standardize customer addresses as tickets come in. The Validate Address tool returns lat/long coordinates that feed directly into their routing software, eliminating the 10-15 minutes techs waste per job hunting down vague addresses. The deliverability verdict flags addresses that need a callback before dispatch. The threshold: if your team runs fewer than 20 service calls per week, manual address cleanup is faster than setting up the API key and integration. Above that volume, the time saved on routing and callbacks justifies the per-call cost. The Provide Validation Feedback tool helps Google improve results in your service area over time.

When this MCP cleans legacy contact databases

A 4-person sales team inheriting a 5,000-contact CRM with inconsistent address formatting uses this MCP to batch-validate mailing addresses before a direct mail campaign. The Validate Address tool standardizes formatting, flags moved or demolished addresses, and returns USPS-compliant versions that reduce postage waste. The geocode output helps segment contacts by region without manual zip code lookups. The limit: Google's API pricing makes this viable for one-time cleanup or quarterly refreshes, not real-time validation on every CRM update. If your list is under 500 contacts, manual spot-checking is cheaper. Above 2,000 contacts, the MCP saves days of work and cuts undeliverable mail by 40%.
