## Agent access

The platform-managed ChatGPT connector uses https://entityreach.sens663.chatgpt.site/mcp with its connection flow. An open MCP transport at https://entityreach.com/api/public-mcp exposes the same public product information, resource links and static sample analysis only. Live company data uses /api/v1 and /api/mcp with an activated workspace and EntityReach API key. Search visibility does not require access to private data or model-training permission.
