Sigo Seguros has released a Model Context Protocol (MCP) server that allows personal AI agents, including ChatGPT, Grok Bot and Muse, to quote and sell Texas auto insurance within a conversation. The agent gathers customer information, requests structured estimates from multiple carriers, compares coverage and eligibility details, explains disclosures and completes purchases through Sigo. Buying is live with select Sigo carrier partners, while other prices remain non-binding estimates subject to underwriting, eligibility and state filings. Sigo also launched InsuranceMCP.com, an open directory where insurers, agencies and marketplaces can list MCP servers and connection rules for AI agents. The directory initially lists Sigo's Personal Auto MCP and Commercial Auto MCP. Sigo said it underwrote more than $50 million in Texas personal auto premium while operating as a managing general agent before becoming a licensed agency. The company is connected in ChatGPT and Grok Bot, while its Muse connector awaits Meta's approval.
