Integration

AddressZen integration

AddressZen is a US address data API built on USPS data. Verify and correct a freeform US address into its USPS-standard form with ZIP+4, autocomplete partial addresses and resolve a suggestion into a full address, find and resolve places, and validate email addresses and phone numbers. Account and API key management (key details, usage, lookup logs, licensees, configs), which needs a separate management key, and the CLI sign-up routes are not included. Authentication is an API key (begins ak_) sent as a Bearer token in the Authorization header.

Connect AddressZen How integrations work

Ask it in chat

Say what should happen.
The workflow builds itself.

When this happens, do that in AddressZen.Built from the 7 AddressZen tools below, on the connection you add once.

What you can do with AddressZen

Each of these is one operation on one endpoint, available both as a workflow step and as a tool an AI agent can call on its own. Nothing bundles several operations into one action, so what a run did stays readable afterwards.

Most endpoints run on the free plan. A few, mainly the ones that publish on your behalf, need a paid plan.

Address, 2 operations

autocomplete_addressAutocomplete addressGETReturns address suggestions (a display label and an id) for a partial address; pass a chosen id to resolve_address to get the full address. Free, but keys that autocomplete without resolving are rate limited, then suspended.
verify_addressVerify addressPOSTVerifies and corrects a US address with USPS CASS: returns match (standard lines, ZIP+4, delivery point, DPV, carrier route, county, coordinates) with fit and confidence, or match null and count 0. Billed per answered query.

Place, 2 operations

find_placeFind placeGETReturns up to 10 place suggestions (countries, administrative areas, capitals and other seats) for a query; pass a chosen id to resolve_place. Free, but integrations that never resolve are rate limited, then suspended.
resolve_placeResolve placeGETReturns the full place for a suggestion id from find_place: the suggestion's fields plus coordinates, language and the dataset record. Each call is billed; an unknown id returns 404.

Email, 1 operation

validate_emailValidate emailGETChecks whether an email address is deliverable (result.result: deliverable, not_deliverable, unknown and others). Needs a key licensed for email validation; a validated address is billed, unknown and dead domains are not.

Phone number, 1 operation

validate_phone_numberValidate phone numberGETValidates a phone number with its country code and returns validity, country, national and international formats and the original network. Needs a key licensed for phone validation; every query is billed, invalid numbers included.

Usa, 1 operation

resolve_addressResolve addressGETReturns the full address for a suggestion id from autocomplete_address, in one US-shaped format (address lines, city, state, zip_code) whatever the country. Each successful call is billed; an unknown id returns 404.

Use AddressZen from Claude Code, Cursor or Codex

Connect AddressZen in LiveContext, create an API key in Settings, then add the LiveContext MCP server to your client. Its AddressZen operations become tools the client can call, next to every other integration you connected.

Claude Code

claude mcp add --transport http livecontext https://livecontext.ai/mcp --header "X-API-Key: YOUR_API_KEY"

Codex (~/.codex/config.toml)

[mcp_servers.livecontext]
url = "https://livecontext.ai/mcp"

[mcp_servers.livecontext.http_headers]
"X-API-Key" = "YOUR_API_KEY"

Cursor, Claude Desktop and other JSON configs

{
  "mcpServers": {
    "livecontext": {
      "type": "http",
      "url": "https://livecontext.ai/mcp",
      "headers": {
        "X-API-Key": "YOUR_API_KEY"
      }
    }
  }
}

The workflow builds itself in front of you and picks the endpoints it needs. Drag the steps yourself on the canvas whenever you would rather be explicit.
