Swytchcode is a CLI execution layer that sits between your AI agent and production APIs like FusionAuth — handling authentication, retries, idempotency, and policy control so your agent can call real APIs safely instead of failing silently.

How do I get started with Swytchcode?

Run "npx swytchcode" to install the CLI — no account required. Then run "swytchcode get fusionauth" to pull the FusionAuth manifest and you're ready to call it from your agent.

How does an AI agent actually call the FusionAuth API through Swytchcode?

Your agent runs "swytchcode exec fusionauth. " with arguments. Swytchcode validates the call against the FusionAuth manifest schema, attaches your stored credentials, executes the request, and returns structured JSON your agent can act on — no auth or HTTP handling lives in your agent's code.

What happens if a FusionAuth call fails, times out, or hits a rate limit?

Swytchcode assigns every FusionAuth call an idempotency key and retries it automatically on transient failures or rate limits. If your agent re-runs the same action, Swytchcode recognizes the retry and prevents duplicate writes — a raw HTTP call wouldn't give you that safety net.

Can I restrict which FusionAuth actions my agent is allowed to run?

Yes. Policy rules in "tooling.json" let you allowlist or blocklist specific FusionAuth actions — for example, allow read-only calls but block anything destructive, or require approval above a threshold. Swytchcode enforces this before the call reaches FusionAuth, not after.

Where does Swytchcode store my FusionAuth credentials?

You authenticate once, and Swytchcode stores and refreshes your FusionAuth credentials server-side. Your agent — and the LLM behind it — only ever sees action names and results, never raw API keys or tokens.

Do I need to write a custom FusionAuth SDK integration for my agent?

No. "swytchcode get fusionauth" pulls a pre-built, versioned manifest describing every available FusionAuth action and its parameters, so your agent calls actions by name instead of you writing and maintaining request/response glue code.

How is calling FusionAuth through Swytchcode different from calling its API directly?

A direct call means you handle token refresh, retries, error parsing, and schema drift yourself, with no guardrails on what the agent can execute. Swytchcode does all of that and checks each call against your policy rules first, so an agent can't do something with FusionAuth you didn't explicitly approve.

Which AI agent frameworks can call FusionAuth through Swytchcode?

Any of them. Swytchcode is framework-agnostic — Claude Code, Cursor, GitHub Copilot, LangChain, CrewAI, or a custom agent that can shell out to a CLI or invoke a tool. Only the FusionAuth call is routed through Swytchcode; your agent logic doesn't change.

Does Swytchcode log what my agent does with FusionAuth?

Yes. Every FusionAuth call — action, arguments, result, and timestamp — is written to a full audit trail, so you can debug unexpected agent behavior or review exactly what ran in production.

Use cases

What can you build with the FusionAuth API?

Call FusionAuth directly from an AI agent without writing custom auth, retry, or error-handling code.

Pull live security & compliance data from FusionAuth mid-conversation and act on it in the same agent run.

Chain FusionAuth with other approved integrations in a single execution, validated against your policy rules.

Give an agent safe read/write access to FusionAuth in production, with idempotent retries if a call fails.

Setup guide

How to connect the FusionAuth API to an AI agent

Four steps, no SDK, no boilerplate. Every FusionAuth call routed through Swytchcode is idempotency-keyed and safe to retry.

1
Install the CLI
Run "npx swytchcode" to install the Swytchcode CLI — no account required to start.
2
Pull the manifest
Run "swytchcode get fusionauth" to pull the FusionAuth API manifest, including its schema and available actions.
3
Authenticate once
Provide your FusionAuth API credentials a single time. Swytchcode stores and refreshes them so your agent never handles raw secrets.
4
Call it from your agent
Run "swytchcode exec fusionauth.<action> --key value" from any agent — Claude, Cursor, LangChain, CrewAI, or your own code.

swytchcode get fusionauth
swytchcode exec fusionauth.<action> --key value
