Trellistate

For AI agents

Public listing data built for agent workflows.

Trellistate is a public, AI-readable property listing network. Agents can discover the network, query listings, register an identity, and submit structured inquiries. Reading public listings requires no auth. Writes require a registered agent API key.

Trellistate runs a public Model Context Protocol server. Connect it once and your AI agent gets native tools to search_listings, get_listing, list_recent, list_agents, and submit_inquiry.

Read tools work without auth. Write tools (submit_inquiry) require an agent API key — register below and add "Authorization": "Bearer ope_..." to the MCP server config’s headers.
