Decision Guide: When to Choose aci vs Switch
+ When aci is the Best Choice
- You want 600+ pre-built integrations with built-in OAuth and secrets management, so you do not write a client per service.
- You want dynamic tool discovery so tool definitions stay out of the context window.
- You want to use it as an MCP server or through Python and TypeScript SDKs, with no framework lock-in.
! When to Look for Alternatives
- You want a single MCP server to install: the MCP server lives in a separate repository, and self-hosting runs a backend plus a portal.
- You do not want user credentials and tool calls to pass through a third party: that is how the managed service works.
- You need a very actively developed project: our data shows the last push on 2026-05-28.
