01 // THE PROBLEM

The Integration Hell Problem

Before MCP, every AI-to-tool integration was a custom one-off implementation. M models x N tools created MxN integrations, which does not scale.

Claude ---- custom code ----> Gmail API
Claude ---- custom code ----> Slack API
Claude ---- custom code ----> GitHub API
GPT-4  ---- custom code ----> Gmail API  (duplicate)
GPT-4  ---- custom code ----> Slack API  (duplicate)

Result: O(MxN) integrations. Fragile and duplicated.

Note

Teams repeatedly reimplemented auth, schema mapping, retries, and error handling.
