Counterparty MCP Server

Install

No download needed — just add the config below to your AI client. npx fetches and runs the server automatically.

Claude Desktop

Add to claude_desktop_config.json (how to find it):

{
  "mcpServers": {
    "counterparty": {
      "command": "npx",
      "args": ["-y", "@21e14/mcp-server"]
    }
  }
}

Claude Code

claude mcp add counterparty -- npx -y @21e14/mcp-server

With signing (see Signing & Broadcasting):

claude mcp add counterparty \
  -e SIGNER_PRIVATE_KEY=L1aW4aubDFB7yfras2S1mN... \
  -e SIGNER_ADDRESS=bc1q... \
  -- npx -y @21e14/mcp-server

Manage servers with claude mcp list, claude mcp get counterparty, or claude mcp remove counterparty.

VS Code (Copilot)

Use Ctrl+Shift+P → MCP: Add Server → Stdio, then enter:

npx -y @21e14/mcp-server

Or add to .vscode/mcp.json:

{
  "servers": {
    "counterparty": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "@21e14/mcp-server"]
    }
  }
}

Cursor

Add to .cursor/mcp.json:

{
  "mcpServers": {
    "counterparty": {
      "command": "npx",
      "args": ["-y", "@21e14/mcp-server"]
    }
  }
}

Windsurf

Add to ~/.codeium/windsurf/mcp_config.json:

{
  "mcpServers": {
    "counterparty": {
      "command": "npx",
      "args": ["-y", "@21e14/mcp-server"]
    }
  }
}

ChatGPT

In ChatGPT desktop, go to Settings → Beta Features → MCP Servers, then add:

npx -y @21e14/mcp-server

Any MCP Client

The server speaks stdio. Point any MCP-compatible client at:

npx -y @21e14/mcp-server

That's it. The agent can now query the Counterparty network and compose unsigned transactions.

Signing & Broadcasting

To let the agent sign and broadcast transactions, add a signing key:

{
  "mcpServers": {
    "counterparty": {
      "command": "npx",
      "args": ["-y", "@21e14/mcp-server"],
      "env": {
        "SIGNER_PRIVATE_KEY": "L1aW4aubDFB7yfras2S1mN...",
        "SIGNER_ADDRESS": "bc1q..."
      }
    }
  }
}

This enables the sign_and_broadcast tool. Signing gives the AI agent the ability to spend funds — read the security guidance below.

Bot wallet pattern (recommended)

Generate a fresh keypair offline. Don't reuse an existing wallet or generate keys through the AI.
Fund it with only what you're willing to risk. This is your blast radius.
Use a segwit address. P2WPKH (bc1q...), P2SH-P2WPKH (3...), or P2TR (bc1p...). Legacy P2PKH is not supported.
One key, one address. No HD derivation. Counterparty reuses addresses by design.
Keep main holdings elsewhere. The bot wallet is disposable.

Compose-only mode

Without signing keys, the server returns unsigned transaction hex from all compose tools. You can review and sign offline with your own tooling. This is the safest mode.

Transaction verification

sign_and_broadcast extracts and returns the embedded OP_RETURN data from the transaction before signing — done locally without trusting the API, so the agent can verify the transaction matches what was requested.

Environment Variables

Variable	Required	Description
`COUNTERPARTY_NODE`	No	Counterparty node URL (default: `https://api.counterparty.io:4000`)
`SIGNER_PRIVATE_KEY`	No	WIF-encoded private key for signing
`SIGNER_ADDRESS`	No	Bitcoin address for the signing key
