Discovering MCP Servers
Discover is where you find MCP servers to connect to your AI. MCPBundles maintains a growing library spanning CRM, analytics, email, payments, developer tools, and dozens of other categories.
Opening Discover
- Log in to MCPBundles
- Click MCP Servers in the top navigation
- Open the Discover tab
You'll see a searchable grid of MCP servers, each displayed as a card with key details at a glance.
What's on a Server Card
Each card shows:
- Name and description — What the server does (e.g., HubSpot CRM, Stripe payments)
- Category chip — Color-coded label like "CRM," "Payment Processing," or "Developer Tools"
- Tool count — How many tools the server exposes
- Readiness — Whether you can use it now (credentials connected and verified)
- Auth requirements — Which connections (OAuth, API key, etc.) you need

Connecting an MCP Server
When you find a server you want:
- Click the card to open the server detail page
- Connect required services in the Connections section (or use Settings → Credentials first)
- Complete the credential flow:
- OAuth (Google, Slack, GitHub) — Click Connect, authorize in the popup
- API key (Resend, OpenAI, Smartlead) — Paste your key from the provider's dashboard
- No auth (public APIs) — Create a connection and validate
- Validate — Run Validate Now on each connection
- Click Enable if the server is not yet active in your workspace
Once ready, copy the MCP URL from Quick Setup on the server page.
For detailed credential setup, see Setting Up Credentials.
Adding a Remote MCP URL
To connect an external MCP server not hosted on MCPBundles:
- On the MCP Servers page, click Add remote MCP URL (top right)
- Enter the server's MCP URL
- MCPBundles discovers the server's tools automatically
Useful for self-hosted servers, internal company tools, or third-party MCP servers from other platforms.
After Connecting
Once a server is enabled and credentials are verified:
- Tools appear in your AI when you add the MCP URL to your client
- Readiness shows Ready with Credentials valid
- Connected tab lists the server among your workspace servers
What to Do Next
- Connect your AI — Paste the MCP URL into ChatGPT, Cursor, Claude, etc.
- Test in Studio — Try tools before adding to your AI
- Create a custom MCP server — Combine tools into your own server
Tips
- Start with services you already use — Connect credentials for tools you have accounts for first.
- Connect credentials before copying URLs — Servers move from Setup Required to Ready faster.
- Use Connected vs Discover — Discover finds new servers; Connected manages servers already in your workspace.
- Watch tool counts — Large servers expose many tools; your AI client may show a subset based on context.
