Hundreds of versions. Incomplete specs. Undocumented sequences. Swytchcode gives your agent the implementation knowledge the vendor never wrote down, then governs every action it runs in production.
Why Swytchcode
Swytchcode gives agents the implementation knowledge these APIs never documented, then governs every action that runs.
One API can carry years of versions, and a single operation can accept more valid field combinations than anyone documented. Your agent has no way to know which one your workflow needs.
The call returned success. The body carried an error. Your agent logged a win. The action never happened.
A destructive call runs against production instead of test. Nothing stops it mid-flight, and nothing records what happened.
How it works
[00]
Missing context, expired tokens, and undocumented changes break agents silently. Swytchcode catches all of it before the call goes out.

Ways to connect
One execution layer. Pick the surface that fits how you already build.
Connect Cursor, Claude, Codex, and other agents through the Model Context Protocol.






Install once, then get manifests and execute governed API calls from the terminal.
Embed the same execution layer in your apps with JavaScript and Python runtime SDKs.
