Setup
Setup guide
- 11. In Switchy, open Settings > Integrations > MCP Servers and click Add Server. 2. Select Addressfinder from the catalog. 3. Log in to your Addressfinder account at addressfinder.com, navigate to API Keys under your account settings, and copy your API key. 4. Paste the key into Switchy's configuration field and click Connect. 5. Switchy will test the connection by calling the AU Address Autocomplete endpoint with a sample query. 6. Once verified, open any Space and type '@Addressfinder verify this address: 123 George St, Sydney NSW' to confirm the MCP responds. 7. If the tool returns structured address data with coordinates and metadata, the integration is live. 8. For email verification, try '@Addressfinder check if this email is valid: test@example.com' to test the Email Verification API tool.
What teammates see: by default, memories from Addressfinder are scoped to the Space (PROJECT visibility) - you can mark any memory PRIVATE or share it ORG-wide.

@addressfinder verify this Australian address and give me the standardized format with coordinates: 123 Swanston St, Melbourne VIC
I've verified that address against the PAF/GNAF databases. The standardized format is: 123 Swanston Street, Melbourne VIC 3000, Australia. Coordinates: -37.8136° S, 144.9631° E. The address is valid and deliverable according to Australia Post standards. I've also retrieved the SA1 statistical area code (20604110216) and mesh block identifier if you need those for demographic analysis.
This example shows the AU Address Verification tool's core strength: converting messy user input into postal-authority-standard addresses with geocoding. Requires an API key with verification credits. Note that verification consumes API credits per lookup, so batch operations can add up quickly. Best used when address accuracy is critical (shipping, compliance, data cleaning).
@addressfinder I need to validate these 5 email addresses before we send the campaign: john@example.com, sarah@fakeco.xyz, admin@client-domain.com.au, typo@gmial.com, support@verified-vendor.io
I've run email verification on all five addresses. Results: john@example.com is syntactically valid but the domain has no MX records (undeliverable). sarah@fakeco.xyz failed—domain doesn't exist. admin@client-domain.com.au is valid and deliverable. typo@gmial.com caught the typo—did you mean gmail.com? support@verified-vendor.io is valid with active mailbox confirmed. I recommend removing the first two and fixing the typo before sending.
This demonstrates the Email Verification API's multi-layer checks: syntax, DNS/MX records, and mailbox existence. The tool helps prevent bounce rates and protects sender reputation. Be aware that mailbox verification can occasionally trigger spam filters if done at high volume, and some providers block verification pings. Use for critical sends, not bulk scraping.
@addressfinder search for locations matching 'George St' in Australia and summarize which cities have the most results—I'm planning regional office locations
I searched the AU Location Autocomplete database for 'George St' and retrieved 47 matches across Australia. Sydney dominates with 12 distinct George Street entries (CBD, North Sydney, Parramatta, etc.), followed by Brisbane with 6, and Melbourne with 4. Regional centers like Bathurst, Launceston, and Rockhampton each have 1-2. For office planning, Sydney's George Street CBD offers the highest foot traffic and transit access, while Brisbane's results span more suburban zones. I can pull full metadata (coordinates, suburb demographics) for any specific location if you want deeper analysis.
This example pairs the AU Location Autocomplete tool with AI reasoning to synthesize geographic patterns from raw search results. Useful for site selection, market analysis, or understanding address density. The autocomplete API returns partial matches quickly, but you'll need follow-up metadata calls (consuming additional credits) to get coordinates and census data for each location. Works best for exploratory research before committing to detailed lookups.
Use-case deep-dives
When real-time address verification cuts cart abandonment
A 6-person DTC brand ships 200 orders a week across AU and NZ. Their Shopify checkout was leaking 8% of orders to bad addresses—reships cost $40 each. The Addressfinder MCP wires AU Address Autocomplete and NZ Address Metadata into their order-processing agent, which now validates addresses at checkout and flags mismatches before the label prints. The email verification tool catches typos in receipts. This works because their volume stays under 5k lookups/month and the API_KEY setup takes one afternoon. If you're shipping physical goods in AU/NZ and eating resend costs, this MCP pays for itself in week one.
Batch-validating 10k contact records without manual review
A 12-person SaaS company inherited a CRM with 10k Australian leads—30% had incomplete or outdated addresses from trade-show signups. Their ops lead used the AU Address Verification tool through Switchy to batch-process the list overnight, flagging 2,800 invalid records and standardizing the rest with GNAF metadata. The Email Verification API caught another 600 bounced domains. This scenario works because Addressfinder's 17 tools cover the full validation stack and the API_KEY auth means no OAuth dance per user. If your CRM has address fields and you're running AU/NZ campaigns, this MCP turns dirty data into segmentable records in one sprint.
Why location autocomplete beats manual address entry for mobile crews
A 20-person HVAC company runs 8 trucks across Sydney. Dispatchers were typing job addresses into their scheduling tool, which geocoded them wrong 15% of the time—techs wasted 40 minutes a day finding sites. They plugged AU Location Autocomplete into their dispatch agent so the system suggests streets and suburbs as the dispatcher types, then pulls GPS coordinates with Get AU Location Metadata. Jobs now route correctly and the agent pre-fills travel time. This works at their scale (60 jobs/day) because the autocomplete is fast enough for live typing and the metadata includes census boundaries for zone-based pricing. If your field team loses time to bad addresses, this MCP turns dispatch into a one-click workflow.
Frequently asked
What does the Addressfinder MCP do in Switchy?
It lets AI agents validate and autocomplete addresses across Australia, New Zealand, and international markets. You can verify email addresses, standardise postal addresses against official databases like PAF and GNAF, and retrieve geocoordinates or census metadata. Useful when your team needs clean address data for CRM imports, logistics workflows, or customer onboarding.
Do I need an Addressfinder account to use this MCP?
Yes. You need an active Addressfinder subscription and an API key from your account dashboard. Switchy uses that key to authenticate requests on behalf of your team. The MCP doesn't create accounts or offer a free tier—billing happens directly between you and Addressfinder based on your usage.
Can it validate addresses outside Australia and New Zealand?
Yes, the MCP includes an international address autocomplete tool and metadata retrieval for global addresses. Coverage depends on Addressfinder's underlying datasets, which vary by country. Australian and New Zealand addresses get the most detailed validation because they're matched against official postal databases. For other regions, expect street-level autocomplete but less granular metadata.
Why use this instead of Google Maps API for address validation?
Addressfinder specialises in postal-authority datasets like Australia Post's PAF and New Zealand's LINZ data. If you need compliance-grade address standardisation for billing, shipping, or government forms, this is more accurate than geocoding APIs. Google Maps is better for routing and place discovery; Addressfinder is better for matching addresses to official records.
Who on the team should connect the Addressfinder MCP?
Whoever manages your Addressfinder account and holds the API key. This is usually someone in ops, data, or engineering. Once connected in Switchy, any team member can invoke the tools through AI agents without needing their own Addressfinder credentials. Usage counts against your Addressfinder plan limits, not Switchy's.
