ArchieSI searches licensed collections from architecture firms and answers with the drawings it used. Every answer cites the source asset and the firm, and every call is written to that firm's usage log.
The MCP endpoint is live at https://archiesi.com/mcp. Sign in with OAuth. Claude, Cursor, and other MCP clients discover sign-in from https://archiesi.com/.well-known/oauth-protected-resource.
Tools
search_catalog(query, image?, filters) returns ranked asset cards plus a ranked firm list. Show the View and License links beside each result you mention.
get_asset_card(asset_id) returns card data, preview link, license terms, and price. Show the View and License links beside the result.
compare_assets(ids) returns a side-by-side comparison. Show the View and License links beside each result you mention.
explore(question, image?, max_firms) runs cross-firm discovery and returns a cited synthesis. Show the View and License links beside each result you mention.
ask_firm(firm, question) runs RAG scoped to one firm and returns an answer with cited asset IDs. It replaces v3's ask_firm_assistant. Show the View and License links beside each citation you mention.
request_license(asset_id, terms, project) returns the site License & download URL. Show that link. Sign-in and checkout stay on the site. There is no in-chat purchase.
get_delivery_link(license_id) returns an expiring link for the Revit plugin or download.
request_license returns a link to the item page on archiesi.com (ref=mcp). The buyer signs in there and confirms checkout. get_delivery_link returns a 15-minute download link for a license that buyer already holds. Taken-down items cannot be licensed or downloaded.
Claude
Add a custom connector whose URL is https://archiesi.com/mcp. Claude returns to https://claude.ai/api/mcp/auth_callback. That callback is already on the MCP client.
ChatGPT
In developer mode, create a custom connector with the MCP server URL https://archiesi.com/mcp and OAuth. ChatGPT shows a callback https://chatgpt.com/connector/oauth/{callback_id}. Add that exact URL to the existing MCP client, then finish sign-in. Do not create a new client. search_catalog and explore show a result grid in the chat. get_asset_card shows one card.
Claude Code has to use loopback port 8080. Cognito matches the port, and that port is the one registered for this client:
claude mcp add --transport http archie https://archiesi.com/mcp --callback-port 8080
Cursor's redirect is https://www.cursor.com/agents/mcp/oauth/callback. The local callback is http://localhost:8787/callback. Cognito does not accept the cursor:// scheme, so that older desktop fallback is not registered.
