What it is
Plug amnt agents into Claude, Cursor or any MCP client as callable tools. One URL, one key, paid from your credit balance.
POST https://www.amnt.io/api/mcpMCP — the Model Context Protocol — is how an assistant like Claude discovers and calls tools. amnt runs an MCP server: point your client at it and the agents you choose show up as tools, with their inputs already described. When the assistant calls one, credits come out of your balance and the creator gets paid, exactly as if you had run it yourself.
You: Write shop copy for the walnut lamp, then make a picture of it.
Claude: [calls alice__product-description] → 3 credits
[calls studio__logo-mark] → 12 credits
Here is the copy and the image...Why bother
| 🔌 No plumbing | No API client, no key per provider, no glue code. One config block |
| 🎯 Specialists on tap | An agent someone tuned for one job usually beats a general model doing it from scratch |
| 👀 Spend you can see | Every tool description states its price in credits, so the assistant — and you — see the cost before it calls |
| 🌍 Your agents everywhere | Publish once on amnt and it is available in every MCP client you use |
How it works
It asks for the tool list. We return the agents that key is scoped to, capped at 25, each with a JSON Schema built from the agent's published fields.
When a tool is called we charge, run, refund on failure, pay the creator, and return the result as MCP content.
Same rails as everything else
The MCP server is a thin door onto the same runner the website and the REST
API use. Same prices, same refunds, same balance, same rate
limit — a tools/list counts as one
request.

Which agents appear, how they are named, and the 25-tool cap.
Troubleshooting
No tools showing, 401s, and the fixes that actually work.
Prefer plain HTTP?
The REST API does the same thing from your own code.
Protocol details
- Transport: Streamable HTTP. One POST endpoint, JSON responses. No SSE — no amnt tool streams today.
- Protocol version:
2025-06-18. - Methods:
initialize,notifications/initialized,tools/list,tools/call. No resources or prompts yet. - Sessions: an
Mcp-Session-Idis issued on initialize and echoed back, but no server-side state hangs off it — every request is authenticated by its key alone. - A plain
GETon the endpoint returns server info, which some clients use as a liveness probe.
