Acuris MCP Server

Model Context Protocol server for the Acuris Address Validation & Geocoding API. Plug Acuris into Claude Desktop, Claude Code, Cursor, or any MCP-aware client and your agent gains four address tools:

Tool	What it does
`validate_address`	Validate any postal address in 240+ countries. Returns standardised address, rooftop coordinates, confidence score (A-F), UDPRN + UPRN for UK.
`postcode_lookup`	Given a UK postcode, return every Royal Mail PAF delivery point at it.
`geocode`	Convert an address into latitude + longitude.
`reverse_geocode`	Convert a lat/lng into the nearest known address.

Quick start

Get a free API key (100 free validations, 100 free geocodes, 7 days, no credit card) at api.acuris-geo.com/register.

Claude Desktop

Add this to claude_desktop_config.json:

{
  "mcpServers": {
    "acuris": {
      "command": "npx",
      "args": ["-y", "@acuris-geo/mcp-server"],
      "env": { "ACURIS_API_KEY": "acu_…" }
    }
  }
}

Restart Claude Desktop. The four tools appear under the "Acuris" server.

Claude Code

claude mcp add acuris -e ACURIS_API_KEY=acu_… -- npx -y @acuris-geo/mcp-server

Cursor / Codex / any MCP client

The server speaks plain stdio MCP. Point your client at:

ACURIS_API_KEY=acu_… npx -y @acuris-geo/mcp-server

Example prompts

After installing, try:

Validate this address: 10 Downing Street, London, SW1A 2AA

Look up every address at the UK postcode M1 1AD

What's the rooftop coordinate for the Reichstag, Berlin?

What address is at 51.5036, -0.1277?

The agent picks the right tool, calls it, and reads the JSON back to you.

Why an MCP server?

No other UK / EU address-validation provider (Ideal Postcodes, Loqate, Smarty, postcoder, getaddress.io) ships an MCP server today. If your team builds with agentic IDEs, Acuris is the only AV provider that hands you a first-class integration.

API surface

The server talks to:

POST https://api.acuris-geo.com/validate
POST https://api.acuris-geo.com/postcode-lookup (GBR — proxied to paf.acuris-geo.com internally)
GET https://api.acuris-geo.com/geocode
GET https://api.acuris-geo.com/reverse

UK requests are automatically routed to our PAF satellite (paf.acuris-geo.com) where the licensed Royal Mail PAF dataset lives. The caller doesn't need to know this.

Development

npm install
npm run build
ACURIS_API_KEY=test node dist/index.js   # smoke-test with the public test key
