Blix MCP · 20 tools · free

Solana memecoin MCP server

Blix MCP turns the Blix API into 20 tools an AI client can call. Ask Claude what is running on pump.fun right now, who holds a coin and whether the dev sold, or have it paper-trade a call. It is free, open source and has no dependencies, and it reads only, plus a paper-money desk: nothing it does can spend real funds.

Needs

Blix running on the same machine (or BLIX_URL)

Set it up in two steps

1. Run Blix

git clone https://github.com/blixvip/blixtrade.git
cd blixtrade
npm start
# dashboard and API on http://localhost:4420

2. Add the server to your client

Use the folder you cloned in place of /path/to/blixtrade. On Windows that looks like C:\\Users\\you\\blixtrade\\mcp\\blix-mcp.mjs inside JSON.

Claude Code

Run once in a terminal.

claude mcp add blix -- node /path/to/blixtrade/mcp/blix-mcp.mjs

Claude Desktop and Cursor

Add to claude_desktop_config.json or ~/.cursor/mcp.json.

{
  "mcpServers": {
    "blix": {
      "command": "node",
      "args": [
        "/path/to/blixtrade/mcp/blix-mcp.mjs"
      ]
    }
  }
}

Codex

Add to ~/.codex/config.toml.

[mcp_servers.blix]
command = "node"
args = ["/path/to/blixtrade/mcp/blix-mcp.mjs"]

VS Code

Add to .vscode/mcp.json.

{
  "servers": {
    "blix": {
      "type": "stdio",
      "command": "node",
      "args": [
        "/path/to/blixtrade/mcp/blix-mcp.mjs"
      ]
    }
  }
}

Running Blix on another port or machine? Set BLIX_URL (for example http://localhost:4421) in the client's environment for this server.

The 20 tools

Every tool is one call of the API. Lists are trimmed for a model: each tool takes limit (rows per list, default 10, max 50), picture fields are dropped and long text is shortened.

Things to ask it

• "What is running on pump.fun in the last five minutes? Skip anything where bundles hold more than 20%."
• "Is the dev still holding <mint>? Show the top holders tagged sniper or bundle."
• "Quote a 0.5 SOL buy of <mint> and tell me the price impact."
• "Paper-buy 0.25 SOL of the strongest Final stretch coin with a 2x take-profit and a 40% stop."
• "Summarise today's narratives and the coins leading each one."
• "How have Blix's dump warnings done this week? Show the track record."

How it works

The server is one file, mcp/blix-mcp.mjs. Your client starts it over stdio; it answers initialize, tools/list and tools/call, and turns each call into an HTTP request to Blix on localhost:4420. Tools that only read are marked read-only to the client; the two paper-desk tools are not. The tool list is one module shared with Blix's own MCP page, so the docs cannot drift from what the server offers.
