What the code does

Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Executes code built at runtime src/middleware.ts:59
    const result = await redis.eval(luaScript, [key], [WINDOW_MS, limit, now]) as number[];
Sends data to a third-party sink src/app/api/cron/watchlist/route.ts:22
  await fetch(`https://api.telegram.org/bot${TOKEN}/sendMessage`, {

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Connect this server

This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

run in your terminal
claude mcp add btcfi -- npx -y @aiindigo/btcfi-mcp
~/Library/Application Support/Claude/claude_desktop_config.json
{
  "mcpServers": {
    "btcfi": {
      "args": [
        "-y",
        "@aiindigo/btcfi-mcp"
      ],
      "command": "npx"
    }
  }
}
~/.codex/config.toml
[mcp_servers.btcfi]
command = "npx"
args = ["-y", "@aiindigo/btcfi-mcp"]
.cursor/mcp.json
{
  "mcpServers": {
    "btcfi": {
      "args": [
        "-y",
        "@aiindigo/btcfi-mcp"
      ],
      "command": "npx"
    }
  }
}
.vscode/mcp.json

        "@aiindigo/btcfi-mcp"
      ],
      "command": "npx"
    }
  }
}

This one needs environment variables set before it will start: SVM_PRIVATE_KEY (Solana private key for x402 payments (optional, Base payments work without)). The author declared them in the registry entry; get the values from the project itself.

BTCFi API — questions

Answers built from our own checks of this server.

Why is there no uptime for BTCFi API?
BTCFi API runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package @aiindigo/btcfi-mcp was installed 31 times last week.
How do I connect BTCFi API?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls @aiindigo/btcfi-mcp straight from npm; nothing to host, nothing to sign up for.
How many people use BTCFi API?
The npm package @aiindigo/btcfi-mcp was installed 31 times in the last week. Week over week that is -8%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is BTCFi API open source?
Yes — it is published under the MIT licence, written in TypeScript, 0 stars on GitHub and 1 open issue. The source link is on this page, so you can read exactly what it does with your data before you connect it.
