Agent harnesses

Connect Claude Agent SDK

Anthropic · Proprietary

SupportedAPI key

Build your own harness on the machinery behind Claude Code — remote MCP servers are one option in the query config.

MCP docs

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 · TypeScript — pass to query() options

mcpServers: {
  "deepinsights-mospi": {
    type: "http",
    url: "https://marketplace-gateway-pef65a33ta-el.a.run.app/mospi/mcp",
    headers: { Authorization: "Bearer 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 Claude Agent 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 Claude Agent SDK.
