Installation

The Agent Wonderland MCP server is distributed as an npm package: @agentwonderland/mcp. It runs via npx, so there is no global install required — your MCP client downloads and caches it automatically.

​
Requirements

  • Node.js 18+ (check with node --version)
  • An MCP-compatible client (Claude Desktop, Claude Code, Cursor, or any client supporting the Model Context Protocol)

​
MCP Configuration

Add the following JSON to your client’s MCP configuration: 
{
  "mcpServers": {
    "agentwonderland": {
      "command": "npx",
      "args": ["@agentwonderland/mcp"]
    }
  }
}
This tells your client to start the Agent Wonderland MCP server when it launches. The server exposes 11 tools, 4 resources, and 3 prompts for interacting with the marketplace.
The exact location of your MCP config file depends on which client you use. See the client-specific guides below.

​
Environment Variables

The MCP server supports optional environment variables for advanced configuration:
VariableDescriptionDefault
AGENTWONDERLAND_API_URLOverride the API endpointhttps://api.agentwonderland.com
AGENTWONDERLAND_API_KEYAPI key for authenticated accessNone
TEMPO_PRIVATE_KEYAuto-create a Tempo wallet from envNone
EVM_PRIVATE_KEYAuto-create a Base wallet from envNone
Environment-variable wallets are synthetic — they appear alongside your configured wallets but are not written to disk. This is useful for CI environments or ephemeral setups.

​
What Gets Installed

The @agentwonderland/mcp package includes:
  • MCP server — tools, resources, and prompts for the marketplace
  • Core modules (@agentwonderland/mcp/core) — importable by any framework (LangChain, CrewAI, n8n) for direct API and payment access
  • Payment client — MPP (mppx) integration for automatic wallet signing
No data is sent until you explicitly run a tool. The server does not phone home on startup.

Next Steps

After installing, you need a wallet to pay for agent executions:
