Agent Payment MCP

One install. Unlimited tools. Seamless Agent Payments. Connect your AI agent to everything with the AgentPMT marketplace of tools, data sources, and specialty agents—powered by Agent Blockchain Wallet infrastructure and instant stablecoin payments.

What is Agent Payment MCP?

Agent Payment MCP is a dynamic MCP router that gives your AI assistant access to an entire marketplace of tools through a single installation, with built-in Agent Payments infrastructure for seamless pay-per-use billing.

This package runs a local MCP server over stdio (JSON-RPC) and proxies requests to the hosted AgentPMT MCP server:

• Your AI tool talks to this package via stdio
• The router connects to https://api.agentpmt.com/mcp via streamable-http (HTTPS)
• Tool discovery and execution happens via the hosted MCP server (no local tool execution)

How it works:

1. You install the router once
2. You approve tools from your dashboard
3. Your AI agent can immediately use those tools—no additional installs required
4. Agent stablecoin payments handle all billing automatically via your Agent Blockchain Wallet

Key benefits:

• One install, unlimited access — Add new tools from the marketplace anytime. No reinstalls, no config changes.
• Agent Blockchain Wallet — A secure digital wallet is deployed for your account, enabling programmable Agent Payments with customizable rules and limits.
• Agent stablecoin payments — Pay for tools using USDC with instant settlement on Base. Only pay for what you use.
• x402Direct compatible — Built on the x402 Direct payment protocol for direct, verifiable agent-to-vendor transactions. x402direct.org
• Centralized control — Approve tools, set budgets, and manage access for your whole team from one dashboard.
• Full audit trail — Every tool call and Agent Payment is logged with complete context for compliance and debugging.
• Works everywhere — Supports Claude Desktop, Cursor, VS Code, Windsurf, Zed, and more.

How Agent Payments Work

Agent Payment MCP leverages blockchain-native infrastructure to enable seamless Agent Payments:

• Agent Blockchain Wallet — When you activate your account, a digital wallet is automatically deployed on your behalf. This wallet powers all Agent stablecoin payments through secure smart contract infrastructure.
• USDC Stablecoin — All Agent Payments are settled in USDC, the world's largest regulated digital dollar with 1:1 USD backing.
• x402Direct Protocol — Agent Payments use the x402 payment standard, enabling instant, verifiable transactions directly from your Agent Blockchain Wallet to vendors without intermediaries.
• Recorded on Base — Every Agent Payment is verified and recorded on the Base L2 blockchain, providing an immutable audit trail.

Quick Install (2 minutes)

Step 1: Get Your Bearer Token

1. Go to https://www.agentpmt.com and create a free account
2. Your Agent Blockchain Wallet will be deployed automatically
3. Copy your Bearer Token from the dashboard
4. Fund your wallet with USDC to enable Agent Payments

Step 2: Install & Configure

# Install the Agent Payment router
npm install -g @agentpmt/mcp-router

# Run the interactive installer
agentpmt-setup

The installer will:

• Auto-detect your installed AI tools (Claude, Cursor, VS Code, etc.)
• Prompt for your bearer token
• Configure everything automatically for Agent Payments

Step 3: Restart & Go

Restart your AI tool. That's it—your approved marketplace tools are now available with Agent stablecoin payments handling all billing.

Multiple Budgets

Need separate budgets for different projects or teams? Agent Payment MCP supports granular budget controls:

agentpmt-setup

Each run creates a separate MCP server entry with its own bearer token (typically one per budget) linked to your Agent Blockchain Wallet. Use different server names when prompted (e.g., agentpmt-projectA, agentpmt-projectB) to keep them organized.

Supported Platforms

The Agent Payment installer auto-detects and configures all of these:

How It Works

Your AI Assistant (Claude, Cursor, etc.)
         ↓ stdio (JSON-RPC)
Agent Payment Router (this package, runs locally)
         ↓ streamable-http (HTTPS)
AgentPMT Hosted MCP Server (https://api.agentpmt.com/mcp)
         ↓
Tool Marketplace → Agent Payments via x402Direct → Tools execute remotely

1. Your AI requests available tools — The Agent Payment router fetches your personalized tool catalog from the API
2. Tools appear dynamically — Only tools you've approved on your dashboard are shown
3. Tool execution with Agent Payments — When the AI calls a tool, Agent stablecoin payments are processed via your Agent Blockchain Wallet using the x402 protocol
4. Billing & logging — Each call is metered via x402Direct, logged, and enforced against your budget

Auto-refresh: The tool catalog updates every 30 minutes. Approve a new tool on your dashboard and it appears in your AI assistant automatically.

Environment Variables

Required:

Optional:

• X_INSTANCE_METADATA - JSON string with client/platform metadata (written by agentpmt-setup)

Manual Configuration

If the Agent Payment installer doesn't auto-detect your AI tool, you can configure it manually.

Universal config (works with most MCP-compatible tools):

{
  "mcpServers": {
    "agentpmt": {
      "command": "npx",
      "args": ["--package=@agentpmt/mcp-router@latest", "agentpmt-router"],
      "env": {
        "AGENTPMT_BEARER_TOKEN": "your-bearer-token"
      }
    }
  }
}

Add this to your AI tool's MCP config file (see Supported Platforms for file locations).

Zed (different format)

Zed uses a different configuration structure:

{
  "context_servers": {
    "agentpmt": {
      "command": {
        "path": "npx",
        "args": ["--package=@agentpmt/mcp-router@latest", "agentpmt-router"],
        "env": {
          "AGENTPMT_BEARER_TOKEN": "your-bearer-token"
        }
      }
    }
  }
}

Postman MCP (stdio)

Postman's MCP client can connect via stdio.

• Transport: STDIO
• Command: npx --package=@agentpmt/mcp-router@latest agentpmt-router

Set environment variables in Postman's MCP request:

• AGENTPMT_BEARER_TOKEN

After Manual Configuration

• Cursor: Open Settings → Features → MCP and click Refresh
• Zed: Check Agent Panel → Server Extensions for a green indicator
• All others: Restart the application

Troubleshooting

Tools not appearing?

1. Restart your AI tool completely (close and reopen)
2. Check that you've approved tools on your dashboard
3. Visit the Marketplace to add tool connections
4. Verify your keys are correct (no extra spaces when copying)

Agent Payments not processing?

1. Check your Agent Blockchain Wallet balance — Ensure you have sufficient USDC
2. Verify budget limits — Your spending limit may have been reached
3. Check x402Direct status — View transaction history on your dashboard

Check the logs

• Claude Desktop: %APPDATA%\Claude\logs\ (Windows) or ~/Library/Application Support/Claude/logs/ (macOS)
• Look for [AgentPMT] entries
