Agent harnesses

Connect OpenAI Agents SDK

OpenAI · MIT

SupportedAPI key

OpenAI's open-source agent framework — remote MCP servers attach to any agent as hosted tool collections.

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 · Python

from agents.mcp import MCPServerStreamableHttp

deepinsights_mospi = MCPServerStreamableHttp(params={
    "url": "https://marketplace-gateway-pef65a33ta-el.a.run.app/mospi/mcp",
    "headers": {"Authorization": "Bearer mk_…"},
})
# pass via Agent(mcp_servers=[…])
  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 OpenAI Agents SDK 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 OpenAI Agents SDK.
