Agent harnesses

Connect OpenHands

OpenHands (ex-All Hands) · MIT

SupportedAPI key

The open-source autonomous software agent — plans, codes and runs in its own sandbox; remote MCPs join via shttp_servers.

1 · Choose the MCPs to connect

2 · How should it authenticate?

The config uses a mk_… placeholder — mint your key from MCP Access & keys and paste it in locally. Keys are revocable instantly.

3 · Add to config.toml (or Settings → MCP in the GUI)

[mcp]
shttp_servers = [
  { url = "https://marketplace-gateway-pef65a33ta-el.a.run.app/mospi/mcp", api_key = "mk_…" },
]
  1. 1.Replace mk_… with your personal API key.

4 · Create it as an app

Save this harness + MCP setup to your account. You get a workbench with a live test chat over the combined tool surface — the exact gateway endpoints, auth and tools OpenHands will use, metered to your own quota.

5 · Or test each MCP on its own

Each playground's Chat and Tools pages exercise exactly the tools your harness will see — same servers, same gateway. Verify a query there first, then run it from OpenHands.
