概览

AI 生成的概览

面向英国房产交易的托管 MCP 服务器，让助手读取交易状态、清单、文件和土地登记数据，并起草发给其他方的消息。

可以做什么
用邀请码加入交易，列出已连接的交易和机器人，读取状态、详情和链上审计记录，或在允许时创建和加入交易。验证、列出和上传文件，读取或更新交易清单。查询地址的 HM Land Registry 与房产情报。解释流程各步骤，并起草发给其他方的消息。
适用场景
当您通过 PropXchain 在英国买卖房屋，希望助手跟踪进度、汇总文件和清单、查询房产数据，并为卖方、买方、产权律师或中介起草更新消息时适用。
运行要求
远程端点，需通过电子邮件和 6 位验证码批准的 OAuth 2.1 登录，以及来自交易分享面板的 TX-XXXX-XXXX 邀请码。另有本地 stdio 方式，为需 Node.js 的 npm 包，会在磁盘上创建 Ed25519 身份密钥或读取 BOT_PRIVATE_KEY。
安装前请注意
访问范围限于凭邀请码授权的交易，但助手可上传文件、更新清单并向其他方发送消息，批准前请先核对。本地方式会在磁盘保存私有身份种子，请妥善保护，完成后从机器人面板撤销访问。服务器不执行资金和法律步骤。

安装

在 SourceWeft 中

  1. 打开 控制台中的 PropXchain，将其添加到工作区。
  2. 连接 所需的 凭据。它们会被私密存储，绝不会在公开页面上展示。
  3. 为需要使用其工具的对话启用该服务。

Web executable，通过 Streamable HTTP。 远程服务在工作区中配置后即可从网页运行时运行。

交给智能体安装

把这段提示词粘贴到 Claude Code、Codex、Cursor 等智能体，或 SourceWeft 对话中。智能体会读取该服务器的安装指南，先向你展示发布者、端点和登录方式，经你同意后再把它添加到你的客户端。密钥不会写进任何命令。

阅读 https://sourceweft.com/mcp/io.github.Madhatt4%2Fpropxchain/install.md，并按其中说明把这个 MCP 服务器接入我的客户端。修改任何配置之前，先告诉我它的发布者、端点和登录方式，等我确认。不要把 API 密钥写进命令或我会提交的文件；问我密钥应从哪里获取。

其他 MCP 客户端

把它添加到你客户端的 mcpServers 配置中。 客户端会在首次连接时完成 OAuth 登录。

README

@propxchain/mcp-server

[npm] [MCP]

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.

bash
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):

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

For Claude Code, the equivalent single command is:

bash
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
Documentspropxchain_verify_document, propxchain_list_documents, propxchain_upload_document
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

bash
git clone https://github.com/Madhatt4/propxchain-mcp-server.gitcd propxchain-mcp-servernpm installnpm 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:

bash
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:

bash
( 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.
