AI agent protocol selector

Answer five quick questions about what you're building. We'll suggest a starting point — MCP, A2A, Agent Protocol, a custom API, or a hybrid — and explain why. Nothing leaves your browser.

1
Are you connecting an AI agent to tools or data?

e.g. databases, APIs, files, internal systems the agent should read or act on.

2
Are multiple agents communicating with each other?

e.g. one agent delegating a sub-task to another specialised agent.

3
Do you need an API-style interface to your agent?

e.g. clients start a run, poll for steps and fetch results over HTTP.

4
Are you building enterprise workflows?

e.g. multi-step, auditable processes spanning several systems or teams.

5
Do you need interoperability across tools or vendors?

e.g. components built by different teams or companies must work together.
