“Agent-facing access to PropXchain UK property conveyancing transactions on the Internet Computer: read transaction state, phase and checklist status, document proofs and property intelligence, and join a transaction via its TX-XXXX-XXXX invite code. The service endpoint speaks Model Context Protocol (JSON-RPC over streamable HTTP); the tools below are exposed as MCP tools rather than A2A message/send tasks.

DANE / TLSA: Not verified
Discovery: Well-known document
This host also publishes an ARD catalog (/.well-known/ai-catalog.json) declaring 4 resources. The catalog's entries are the publisher's claims, not something agenttru.st verified.
AI use policy: Search: yesAI input: yesAI training: yes

What this site's robots.txt says about how AI may use its content. Recorded as the operator wrote it, not enforced — these are preferences about use, not access, and agenttru.st only reads the agent's own discovery documents.
AI-facing documents: Publishes /llms.txt — “PropXchain” a curated map of the site's content for language models

Publishes a Web Bot Auth key directory (1 key, EdDSA) — the operator publishes keys so their agent's signed requests can be verified. agenttru.st recorded that the directory exists; it has not verified a signature.

What this agent says it can do

Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of propxchain.com controls every word below.

Join a transaction by invite code

Adds the agent to a transaction's access list using the TX-XXXX-XXXX invite code the user shares. Idempotent.

transactionsonboarding

Examples it gives

Join transaction TX-1234-ABCD as my assistant

Read transaction state

Returns a transaction's parties, phase, status, chain of linked transactions and outstanding items.

transactionsstatus

Examples it gives

What's outstanding on my sale?
List my PropXchain transactions

Track and update the conveyancing checklist

Reads phase checklists and marks items complete where the agent has been granted write access.

checklistsworkflow

Examples it gives

Which checklist items are still open?

Register and verify documents

Lists documents on a transaction, registers a document's SHA-256 hash on-chain and verifies a file against its on-chain proof. Files never leave the user's device.

documentsproofs

Examples it gives

Verify this TA6 against the chain

Property intelligence

Returns HM Land Registry title data, search results and address intelligence for a property on a transaction.

propertyhmlrsearches

Examples it gives

Message transaction parties

Posts a message into the transaction's shared thread visible to seller, buyer, conveyancer and agent.

Plain-English explanation of any stage of a UK sale or purchase and what the next step is.

education

Examples it gives

What its catalog declares

From the ARD catalog this host publishes at /.well-known/ai-catalog.json. The operator controls every entry; agenttru.st verified that the catalog exists and parses, and nothing about what the entries say.
