MCP (Model Context Protocol) is an open standard that lets AI models connect to external apps and take real actions in them. In Mushrooms, you get a personal MCP server URL — paste it into your AI client and your AI instantly has access to every app you've connected.

Mushrooms is an app connection layer for AI clients. Connect Claude, ChatGPT, Cursor, or any MCP-compatible AI to the apps you use — Gmail, Slack, GitHub, Notion, and 2,000+ more — and your AI gains the ability to take real actions in those apps. Read emails, create tasks, post messages, pull data. Not just talk about it — do it.

Which AI clients does Mushrooms work with?

Mushrooms works with any AI client that supports MCP — including Claude, Cursor, ChatGPT, Windsurf, Gemini, GitHub Copilot, Cline, Zed, Cody, and other MCP-compatible clients. More are added continuously.

Yes — Mushrooms is free for lifetime under a fair usage policy, with no rate limits. Connect your AI client, add apps, and start taking real actions at no cost. No credit card required.

Yes. Every app connection uses OAuth — you authorise exactly what your AI can and cannot do, action by action. Credentials are never stored in plain text, connections can be revoked at any time, and your data stays within your boundary.

Which apps can I connect to my AI using Mushrooms?

2,000+ apps including Slack, Gmail, GitHub, Notion, Linear, HubSpot, Google Calendar, Airtable, Figma, Stripe, Shopify, Microsoft Teams, Salesforce, Jira, Asana, Google Sheets, Dropbox, Zendesk, and more. If it has an API, it's very likely already supported. You can also request any missing app and it will be built within 48 hours.
