Browsing the Catalog
The catalog is where you find and connect services to your AI. MCPBundles maintains a growing library of integrations spanning CRM, analytics, email, payments, developer tools, and dozens of other categories — each ready to connect in minutes.
Accessing the Catalog
- Log in to MCPBundles
- Click Catalog in the left navigation
You'll see a searchable grid of all available integrations, each displayed as a card with key details at a glance.
What's on an Integration Card
Each card shows:
- Name and logo — The service (e.g., HubSpot, Stripe, Slack)
- Category chip — Color-coded label like "CRM," "Payment Processing," or "Developer Tools"
- Tool count — How many tools (API actions) the integration exposes
- Bundle count — How many pre-built bundles include this integration
- Auth type — What kind of credential is needed (OAuth, API Key, Token, or No Auth)
- Connection status — Whether you've already connected credentials:
- Green (Connected) — Credentials verified, tools are live
- Amber (Needs attention) — Credentials exist but have issues
- No indicator — Not yet connected

Connecting an Integration
When you find a service you want to use:
- Click the card to open the provider detail page
- Click "Connect" (or "Add Credential")
- Complete the credential flow:
- OAuth providers (Google, Slack, GitHub) — Click "Connect with [Provider]," authorize in the popup, and you're done
- API Key providers (Resend, OpenAI, Smartlead) — Paste your API key from the provider's dashboard
- No Auth providers (public data APIs) — Click "Create Connection & Test" — no credentials needed
- Validate — Select a validation tool and click "Validate Now" to confirm everything works
Once validated, the integration's tools become available to your AI immediately.
For detailed credential setup instructions, see Setting Up Credentials.
Connecting a Remote MCP Server
The catalog also supports connecting to external MCP servers that aren't in the built-in catalog:
- Click "Connect Remote MCP Server" in the top-right of the catalog page
- Enter the server's MCP URL
- MCPBundles discovers the server's tools automatically
This is useful for connecting to self-hosted MCP servers, internal company tools, or third-party MCP servers from other platforms.
After Connecting
Once an integration is connected and verified:
- Tools appear in your AI — Any bundle that includes this integration will have its tools active
- Card status updates — The card shows a green "Connected" badge
- Bundles unlock — Bundles that required this integration move from "Setup Required" to "Ready" (with "Credentials valid" subtext)
What to Do Next
- Choose a bundle that uses your newly connected integration
- Create a custom bundle with exactly the tools you want
- Test tools in Studio before using them in your AI
Tips
- Start with what you already use — Connect the services you have accounts for first. You'll get value immediately.
- Watch tool counts — An integration with 50+ tools means your AI has a lot to work with. Consider using bundles to curate which tools are exposed.
- Use categories to explore — Even if you have a specific service in mind, browsing a category often reveals complementary integrations you didn't know were available.
- Connect credentials before choosing bundles — It's easier to enable bundles when the underlying providers are already connected.
