BundleUp gives developers a single, unified API to build and manage integrations across services like Slack, GitHub, Salesforce, and more. Call any third-party API through one edge endpoint with built-in OAuth, token refresh, retries, and rate limits, so you can skip standing up integration servers. Use its normalized interface to access common resources across providers without per-provider rewrites, and connect agents to existing MCP servers with managed OAuth.
