The app store for your AI assistant.

A phone ships with built-in apps; you install more to extend it. Claude, ChatGPT and Cursor ship with built-in abilities — B77 apps extend them with your tools and your data. Every app is a hosted MCP server: a Claude connector, a ChatGPT plugin, a Cursor MCP server. Sign in, install, ask.

Each team member asks their own assistant; B77 connects Claude and ChatGPT to the apps that pull records from the tools you already use.

  1. Step 1

    Find

    Pick an app for the tool you already use — project management, ads, analytics, your own knowledge base.

  2. Step 2

    Connect

    Click Install, paste one URL into your assistant and sign in. OAuth, no API keys, nothing to run locally.

  3. Step 3

    Ask

    Ask in plain words. Your assistant now reads and, where allowed, writes to that tool for you.

Why install from B77

Hosted, not self-run

Every app is a remote MCP server B77 operates. No npm, no Docker, no config files — one URL and you are connected from claude.ai, ChatGPT or Cursor.

OAuth 2.1, per user

Access is granted with your own sign-in and scoped to what the app page lists. Credentials live in a per-user vault; every call is audited. How it works →

Curated, EU-hosted

B77 co-builds and operates each listing with its vendor, in EU data centres. Nothing lands in the store unreviewed. Publish yours →
