Anthropic designed MCP and Claude has native support across surfaces. Claude Desktop, Claude Web, and Claude Code all consume MCP servers. The operator points Claude at the CorpusIQ MCP server endpoint, authenticates, and Claude immediately sees every authorized business tool as an available tool surface.
37+ read-only business tool surfaces across email, files, chat, finance, commerce, marketing, CRM, and databases. Each call returns structured records with stable source identifiers so Claude can cite back to the underlying record in its answer.
Every connector is read-only OAuth. Claude can read records you have authorized; it cannot send, modify, move, or delete. CorpusIQ does not store customer files; records are read on demand and released after the answer returns. Customer data is not used to train any model.
Native MCP plus Claude's multi-tool reasoning means a single conversation can pull from QuickBooks (overdue invoices), Gmail (the customer thread), and Drive (the signed contract) and synthesize a coherent answer with cited links to all three. The MCP server provides the read pipes; Claude orchestrates.
