App Actions
App action nodes let your agents interact with external services — send Slack messages, create Linear issues, query PostHog analytics, and more.
Spawnbase connects to apps via MCP (Model Context Protocol) servers. We maintain a curated catalog of verified apps below, but you can connect any service that exposes a public MCP server — the catalog is just the starting point.

Connect Any MCP Server
Section titled “Connect Any MCP Server”Don’t see your app? If the service has a public MCP server, you can connect it directly:
- Open an AI Agent node → Tools → Add Tool → Connect MCP Server
- Enter the server URL and authentication (API key, OAuth, or none)
- Spawnbase discovers the server’s tools automatically
- The connection is saved and available across all your agents
This means anything with an MCP endpoint works with Spawnbase — including internal tools, niche SaaS products, and self-hosted servers. See MCP Servers for details.
How It Works
Section titled “How It Works”- Add the node — open the node picker (
N) and choose an app - Connect your account — click “Connect” in the node configuration panel
- Pick a tool — select what you want to do (e.g., “Send Message” for Slack)
- Map inputs — fill in required fields, reference upstream node outputs with
{{node.field}}syntax
Connection Methods
Section titled “Connection Methods”| Method | How it works | Apps |
|---|---|---|
| OAuth | Click Connect, authorize in browser | Slack, Discord, Notion, HubSpot, Airtable, Sentry, Atlassian, PostPulse |
| API Key | Paste a key from the app’s settings | Stripe, Supabase, Linear, GitHub, Figma, Exa, Apify, Ahrefs, monday.com, Intercom, Close, PagerDuty, PostHog |
| None | No auth needed | DeepWiki, Semgrep, Cloudflare Docs |
All credentials are encrypted and stored securely. You authorize once, then use the connection across all your agents.
