Overview

Description from the maker (original English)

UK property transactions: status, checklists, documents, HM Land Registry intel.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • The registry lists no key to fill in.

You need

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Works in Claude on the web, desktop and mobile:

  1. Open Settings → Connectors
  2. Press Add custom connector
  3. Paste the address below and press Add
  4. If it asks you to sign in, sign in with the maker
SettingsConnectors1+ Add2https://…3
https://mcp.propxchain.com/mcp

Run this in your terminal

claude mcp add --transport http propxchain https://mcp.propxchain.com/mcp

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "propxchain": {
      "url": "https://mcp.propxchain.com/mcp"
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "propxchain": {
      "type": "http",
      "url": "https://mcp.propxchain.com/mcp"
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

ChatGPT connects only to servers on the internet:

  1. Open ChatGPT on the web → Settings → Connectors (Apps)
  2. Press Create or Add (some plans need Developer mode under Advanced first)
  3. Paste the address below, give it a name and save
  4. If it asks you to sign in, sign in with the maker
SettingsConnectors1+ Create2https://…3

Menu names can differ slightly by plan and over time.

Your choice stays on this device in a cookie; no account needed.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Compared with others in Otheri

  • More stars than 0% of the other 32606 servers in this category
  • Published to the registry more recently than 58% of the other 32606 servers in this category
  • Basic checks equal to or better than 100% of the other 32606 servers in this category

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.

Common questions

Is PropXchain safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (2.2.1) reached the registry 28 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

@propxchain/mcp-server

MCP server for PropXchain, the UK platform for selling or buying a home: one shared, live record of the transaction for seller, buyer, conveyancer and estate agent. (Not Propchain/PROPC, the unrelated crypto token.)

Your AI assistant can join your transaction with its invite code, read status, checklists, documents and the audit trail, pull HM Land Registry and property data, explain each step, and draft messages to the other parties. Money and legal steps still wait for you.

Connect (hosted, no install)

PropXchain runs this server for you at:

https://mcp.propxchain.com/mcp
  • claude.ai / Claude Desktop: Settings, Connectors, Add custom connector, paste the URL, leave client ID and secret blank.
  • Claude Code: claude mcp add --transport http propxchain https://mcp.propxchain.com/mcp
  • ChatGPT, Cursor and other MCP clients: add a remote (Streamable HTTP) server with the URL above. Sign-in is OAuth 2.1, discovered automatically.

You approve the connection with your PropXchain email and a 6-digit code, then give your assistant a TX-XXXX-XXXX invite code. Remove it at any time from the transaction's bot panel.

Full setup walkthrough: propxchain.com/agent. Machine-readable manifest: propxchain.com/.well-known/mcp.json. Registry listing: server.json (io.github.Madhatt4/propxchain).

Run it locally instead (stdio)

For hosts without remote MCP support. The local server generates its own Ed25519 keypair on first launch (stored on disk, never copied across boundaries); access is still per transaction via invite code.

npm install -g @propxchain/mcp-server

Then add to your Claude Desktop config (%APPDATA%/Claude/claude_desktop_config.json on Windows, ~/Library/Application Support/Claude/claude_desktop_config.json on macOS, ~/.config/Claude/claude_desktop_config.json on Linux):

{

"mcpServers": { "propxchain": { "command": "propxchain-mcp-server", "env": { "IC_NETWORK": "ic" } } } }

For Claude Code, the equivalent single command is:

claude mcp add propxchain propxchain-mcp-server -e IC_NETWORK=ic

Restart your agent. In a new chat, ask:

*Join propxchain transaction TX-XXXX-XXXX as a bot called "Claude Desktop"*

(Get the invite code from the share panel of any of your transactions on propxchain.com.)

Identity model

On first launch, the server reads or creates an Ed25519 seed at:

  • macOS / Linux: ~/.config/propxchain-mcp/identity.key (or $XDG_CONFIG_HOME/propxchain-mcp/identity.key if set)
  • Windows: %APPDATA%/propxchain-mcp/identity.key

The file is chmod 600 on POSIX and contains a single base64-encoded 32-byte seed plus a trailing newline. The bot's principal is derived from this seed and printed to stderr at startup.

Override for ops or CI: set BOT_PRIVATE_KEY in env to a base64-encoded 32-byte seed. When set, the server uses this instead of reading from disk.

Tools

17 tools across these categories:

CategoryTools
Bot managementpropxchain_join_transaction_as_bot, propxchain_list_my_transactions, propxchain_list_connected_bots
Transactionspropxchain_search_transactions, propxchain_get_transaction, propxchain_get_status, propxchain_create_transaction, propxchain_join_transaction, propxchain_get_transaction_chain

Checklistspropxchain_get_checklist, propxchain_update_checklist
Property intelligencepropxchain_get_property_intel
Educationpropxchain_explain_process, propxchain_send_message

Each tool's full schema is discoverable via the standard MCP tools/list call.

Security model

  • The bot principal only sees transactions the user has granted via invite code.
  • No write surface for funds, signatures, or transactions outside the granted ones.
  • Revocation is one click in the propxchain.com bot panel; calls transaction_manager.disconnectBot on chain.
  • The seed file lives on the user's local machine. The npm package contains no credentials.
  • npm provenance attestation is enabled on every release; verify with npm view @propxchain/mcp-server.

Build from source

git clone https://github.com/Madhatt4/propxchain-mcp-server.git

cd propxchain-mcp-server npm install npm run build

npm run build compiles TypeScript and prepends a #!/usr/bin/env node shebang to dist/index.js (post-tsc, since tsc strips it). Test the binary directly:

node dist/index.js

The server reads/creates the local identity file as above. To smoke-test the MCP protocol roundtrip, pipe an initialize + tools/list request:

( printf '%s\n' \

'{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2024-11-05","capabilities":{},"clientInfo":{"name":"test","version":"1.0"}}}' \ '{"jsonrpc":"2.0","method":"notifications/initialized"}' \ '{"jsonrpc":"2.0","id":2,"method":"tools/list"}' ; \ sleep 2 ) | node dist/index.js

You should see your bot principal in stderr and the tool list in stdout.

Versioning

Releases are published manually via gh workflow run release.yml --field dry-run=false. Bump version in package.json first; the workflow refuses to republish an existing version and refuses pre-release suffixes on the latest tag. Pre-release validation runs the same MCP smoke test shown above before publishing.

License

UNLICENSED. The npm package is freely installable for use against PropXchain canisters; redistribution and modification rights are not granted.
