BundleUp

BundleUp provides a single API endpoint that abstracts the details of third‑party services, allowing developers to authorize integrations, store credentials, and invoke any external API through a normalized interface. After a user completes OAuth flow, a connection identifier is issued; subsequent calls use that identifier to perform actions such as listing chat channels, with built‑in token refresh, retries, and rate limiting handled by the platform. The service also supports a protocol for connecting existing agents to MCP servers, enabling them to focus on execution without managing authentication.

The platform offers SDKs for JavaScript, Python, and Ruby, simplifying connection handling and API requests across common development stacks. By consolidating diverse providers under one provider‑agnostic schema, it eliminates the need for per‑provider code rewrites and removes the requirement for dedicated integration servers.

Targeted at developers building web applications or personal projects, BundleUp’s experimental tier includes a free plan with up to 500 k monthly requests, while a paid tier expands limits and removes branding. The offering is positioned as a unified solution for managing multiple integrations from a single codebase.
