Agenticpay
Expose paid MCP tools that charge USDC per invocation on Solana using the x402 paywall bridge.
Overview
AgenticPay is a MCP server for the Build phase that bridges MCP tool calls to x402 USDC paywalls on Solana.
What is this MCP server?
- stdio npm package @agenticpay/mcp-bridge with x402 USDC pay-per-tool-call flow on Solana
- AGENTICPAY_BRIDGE_TOOLS JSON array defines name, description, url, inputSchema, and optional headers per paid tool
- Bridge signs payments with AGENTICPAY_BRIDGE_KEYPAIR (64-byte solana-keygen JSON array)
- Configurable CAIP-2 network (default devnet) and Solana JSON-RPC via AGENTICPAY_BRIDGE_RPC
- Repository krystiangw/agenticpay — server schema 2025-09-29, package version 0.0.2
- 4 environment variables documented (keypair, tools, network, RPC)
- Default network CAIP-2 solana devnet identifier in server schema
- Package @agenticpay/mcp-bridge version 0.0.2 on npm

What problem does it solve?
You built useful MCP tools but have no simple way to charge per call without custom payment middleware.
Who is it for?
Indie builders monetizing agent tool APIs with Solana USDC micropayments on devnet or custom networks.
Skip if: Teams needing subscription billing, fiat checkout, or MCP tools with no on-chain payment requirement.
What do I get? / Deliverables
Your agent invokes the same MCP tools while the bridge signs and settles USDC payments per configured paid endpoint.
- MCP-accessible paid tools with automatic x402 USDC signing per call
- Configurable Solana network and RPC for devnet or production
- Documented paid-tool catalog mapped to remote URLs and schemas
Recommended MCP Servers
Journey fit
Monetization wiring belongs in Build when you connect agents to external paid APIs and on-chain settlement. Integrations is where MCP bridges, env-configured tool catalogs, and payment headers meet your agent runtime.
How it compares
Solana x402 payment MCP bridge, not a general-purpose skill or hosted API marketplace.
Common Questions / FAQ
Who is AgenticPay for?
Solo and indie builders who run MCP clients and want per-tool USDC charges on Solana via x402.
When should I use AgenticPay?
Use it during Build when wiring paid HTTP tools into MCP and you already have a Solana keypair and tool URLs ready.
How do I add AgenticPay to my agent?
Install @agenticpay/mcp-bridge, set AGENTICPAY_BRIDGE_KEYPAIR and AGENTICPAY_BRIDGE_TOOLS, optionally tune NETWORK and RPC, then register the stdio server in Claude Code, Cursor, or Codex MCP config.
