Connect Cursor to Alphaday

What you're connecting to

One endpoint exposing 22 data capabilities across 57 pre-described tools — news, governance, DeFi, security and market data. It is a remote server, so there is no package to install, no process to keep alive and no key to obtain. That matters for Cursor setup specifically: almost every MCP example online is command + args spawning a local binary, and none of it applies here.

Before you start

The config below assumes all of this is already true. Most failed setups are one of these rather than a wrong field.

• A project open in Cursor if you are using the project-scoped file; nothing in particular for the global one.
• Agent mode. Cursor's Ask mode does not call MCP tools, so a correctly connected server still looks inert there.

Set it up

{
  "mcpServers": {
    "alphaday": {
      "url": "https://api.alphaday.com/mcp"
    }
  }
}

Check it worked

Confirm the connection before you go looking for a bug in your prompt. A server that is listed but not connected looks identical to a model that chose not to call it.

1. 1Settings → MCP, or Cursor Settings → Tools & Integrations depending on build
2. 2alphaday should be listed with a green indicator
3. 3Expand it — the tool list should populate rather than sitting empty

A green server with a populated tool list. An empty list beside a green dot usually means the handshake succeeded but the tool fetch did not; reload the window before changing the config.

curl -s -X POST https://api.alphaday.com/mcp \
  -H 'Content-Type: application/json' \
  -H 'Accept: application/json, text/event-stream' \
  -d '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{
        "protocolVersion":"2025-06-18","capabilities":{},
        "clientInfo":{"name":"curl","version":"1"}}}'

{"jsonrpc":"2.0","id":1,"result":{
  "protocolVersion":"2025-06-18",
  "capabilities":{"tools":{"listChanged":false}, ...},
  "serverInfo":{"name":"alphaday","version":"1.30.0"}
}}

Try it

Ask these in an Agent-mode chat. Each one needs data the model cannot have — a live feed, an incident record, a yield table — so a good answer is proof the tools fired, not just that the server is listed.

• What's trending in crypto news right now, and what changed in the last 24 hours?
• Which DeFi pools are paying over 20% APY, and which of them carry real impermanent-loss risk?
• Summarise the three most recent on-chain exploits and what was taken.
• Compare GitHub developer activity for Solana and Sui over the last month.

When it doesn't connect

Symptom first, because that is what you have. The status codes below were produced against the live server rather than copied from elsewhere — if yours does not appear here, it is worth trusting that difference.

What you get once it's connected

22 datasets, reached by 57 tools — most datasets have a list form, a detail form and a trending form, which is why the two numbers differ. These four are the ones a general crypto API does not have:

All 22 capabilities are listed on the MCP overview, with the tool count behind each.
