MCP server (no streams)

Answers 405 with allow: POST: this server speaks Streamable HTTP without server-initiated streams.

#Authentication

Agent key

An agent-scoped key (ask_...) bound to exactly one agent, or an OAuth access token (aat_...) issued to an MCP client for that agent, sent as Authorization: Bearer. An agent key may ask, poll and settle. It can never approve, widen a mandate or lift a freeze.

Request

curl "https://immiscible.fly.dev/mcp" \
  -H "authorization: Bearer $IMMISCIBLE_AGENT_KEY"

const res = await fetch('https://immiscible.fly.dev/mcp', {
  headers: {
    authorization: `Bearer ${process.env.IMMISCIBLE_AGENT_KEY}`,
  },
});
const data = await res.json();
console.log(res.status, data);

import os
import requests

res = requests.get(
    "https://immiscible.fly.dev/mcp",
    headers={
        "authorization": f"Bearer {os.environ['IMMISCIBLE_AGENT_KEY']}",
    },
)
print(res.status_code, res.json())
