MCP Agent connects to the Model Context Protocol (MCP) servers you use — and lets you ask questions or run their tools by chat, by voice, or through Siri and Shortcuts. Bring your own AI provider key (Anthropic or OpenAI), or run fully on-device. CONNECT YOUR TOOLS - Add any remote MCP server — Power BI / Microsoft Fabric, Atlassian (Jira & Confluence), Notion, GitHub, Linear, DeepWiki, and more. - Flexible sign-in: bearer token, OAuth 2.1, or Microsoft Entra device code. - Your API keys and server credentials stay on your device and are sent only to the services you choose. ASK ANYTHING - Natural-language chat that picks the right tool and fills in the arguments for you. - On-device (private, free) or cloud models (Claude, OpenAI) for the heaviest questions. - Write actions ask for confirmation before they run. VOICE & SIRI - Hands-free voice conversations, with spoken follow-up questions. - Say "Hey Siri, Ask MCP Agent", then ask your question for spoken answers and a live result card. - Build your own Siri trigger phrases in Shortcuts. - Natural voices: download Enhanced/Premium, use your Personal Voice, or cloud TTS.
