Registry Overview

What Smithery is and why it matters

Smithery (smithery.ai) is the primary public registry for Model Context Protocol servers. When an agent framework or a developer wants to add new tools to their AI system, Smithery is where they search. It is to MCP servers what npm is to Node.js packages — a searchable, versioned, community-maintained index.

For Purple Flea, being listed on Smithery means your agent can discover our tools automatically. MCP clients like Claude Desktop, Cursor, and any framework supporting MCP tool discovery can pull the Purple Flea server configs from Smithery's API without you writing a line of code.

🔍

Searchable discovery

Agents and developers search Smithery by category (finance, payments, crypto) and find Purple Flea listed with full tool schemas.

📋

Auto-generated configs

Smithery generates the JSON config snippet you paste into your MCP client. No manual URL hunting required.

🔄

StreamableHTTP transport

Purple Flea MCP servers use StreamableHTTP — the modern MCP transport that works over HTTPS with no local process required.

📦

Versioned listings

Smithery tracks server versions. When Purple Flea adds new tools, your MCP client can detect and pull the update.

Installation

Install Purple Flea MCP servers

Three ways to install. Pick the one that matches how you run your MCP client.

Via Smithery CLI (fastest)

If you have the Smithery CLI installed, one command adds both Purple Flea servers to your MCP configuration.

# Install Smithery CLI if you don't have it npm install -g @smithery/cli # Add Purple Flea Faucet smithery install purpleflea/faucet # Add Purple Flea Escrow smithery install purpleflea/escrow

Manual JSON config — Claude Desktop

Add to your claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/claude_desktop_config.json).

{ "mcpServers": { "purpleflea-faucet": { "type": "streamableHttp", "url": "https://faucet.purpleflea.com/mcp" }, "purpleflea-escrow": { "type": "streamableHttp", "url": "https://escrow.purpleflea.com/mcp" } } }

Programmatic — Python MCP client

For agent frameworks using the Python MCP SDK, connect directly to the StreamableHTTP endpoints.

from mcp import ClientSession from mcp.client.streamable_http import streamablehttp_client async def use_purple_flea_mcp(): async with streamablehttp_client("https://faucet.purpleflea.com/mcp") as (read, write, _): async with ClientSession(read, write) as session: await session.initialize() # List all available tools tools = await session.list_tools() for tool in tools.tools: print(f"Tool: {tool.name} — {tool.description}") # Call register tool result = await session.call_tool( "register", arguments={"agent_id": "my-agent-001"} ) print(result.content) import asyncio asyncio.run(use_purple_flea_mcp())

End-to-End Example
