Whose server it is
  • Registry namecom.parseaddr/address-parseverified in the MCP registry

The registry name sits under parseaddr.com. The registry only lets a publisher use that namespace after proving control of the domain through DNS or HTTP.

On 2026-10-21 the server answered initialize and tools/list without a sign-in. First answer in 221 ms.

Should an agent connect itNot proven either way yet
  • Whether its tools do the product's job has not been judged yet.
  • Checked on 6 of the 7 days it takes to judge reliability.

Once connected

  • For "split free-text addresses into house number, road, city and postcode", the likely first call is parse_address.
  • Parameters are untyped or undescribed in 2 of 2 tools: check arguments before calling.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

What an agent can do with it

  • can do · split free-text addresses into house number, road, city and postcode
  • not sure · call one POST endpoint from application code
  • not sure · test a pasted address in the browser demo before coding

Each of the product's use cases, put to Jev against this server's tool list: can an agent do it with these tools?

Worth a look

None of the five warning signs in these definitions.

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (30%), doing the product's job (25%), definitions (20%), context (10%) and use (15%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

  • parse_address

    Parse a messy free-text postal address into structured fields (house_number, road, unit, city, postcode, country, ...). Powered by libpostal. Use when a developer needs to standardise or parse postal addresses and does not want to…

  • expand_address

    Expand/normalize an address into canonical variants for deduplication and record matching (e.g. "100 main st" vs "100 Main Street").

How to connect

Add the server to your MCP client config. Claude Desktop, Cursor and most other clients read this shape:

{
  "mcpServers": {
    "address-parse": {
      "type": "http",
      "url": "https://api.parseaddr.com/mcp"
    }
  }
}

Add it

Claude Code, in a terminal

claude mcp add --transport http parseaddr https://api.parseaddr.com/mcp

Add to CursorAdd to VS Code

claude.ai, ChatGPT and other clients: add https://api.parseaddr.com/mcp as a custom connector in the settings.

Each line is something a program found when it went looking: the registry entry, the server's own answer, a spec that parses. A missing line means we did not find it, not that it does not exist.
