X402 Mcp
Pull crypto market intelligence through MCP while the server handles x402 USDC micropayments from a dedicated wallet.
Overview
x402-mcp is an MCP server for the idea phase that exposes up to 177 crypto market intel tools with automatic x402 USDC micropayments from your agent wallet.
What is this MCP server?
- Up to 177 crypto market intel tools (default expose limit 100 via X402_TOOL_LIMIT)
- Automatic x402 USDC micropayments on Base, Polygon, Arbitrum (EVM) and optional Solana (SVM)
- stdio npm package @carbon-cashmere/x402-mcp version 0.2.2
- Requires EVM_PRIVATE_KEY; optional SVM_PRIVATE_KEY for Solana USDC
- Paid-per-call intel model suited to agent research sessions not bulk ETL
- 177 crypto market intel endpoints available
- Default X402_TOOL_LIMIT 100 (configurable 1–177)
- npm package version 0.2.2 (@carbon-cashmere/x402-mcp)
What problem does it solve?
Agent-driven crypto research stalls when every data vendor needs custom APIs and you cannot meter paid intel calls safely from the IDE.
Who is it for?
Technical solo builders doing paid, agent-led crypto market research who accept wallet-funded micropayments.
Skip if: Non-crypto products, teams forbidden from hot wallets in dev machines, or users wanting free unlimited market data without USDC.
What do I get? / Deliverables
After npm install and wallet env setup, your agent can call Carbon Cashmere intel tools with x402 settling USDC per request on configured chains.
- Agent-accessible crypto intel tools (1–177 exposed per X402_TOOL_LIMIT)
- Automated USDC settlement per tool invocation via x402
- Research notes and metrics pulled without hand-written vendor integrations
Recommended MCP Servers
Journey fit
Market intel and token metrics support opportunity research before you commit to a crypto or fintech build. Research subphase is where builders compare narratives, liquidity, and on-chain signals; 177 endpoints map to deep discovery queries agents can run early.
How it compares
Micropayment-gated market-intel MCP, not a passive skills.sh coding workflow.
Common Questions / FAQ
Who is x402-mcp for?
Developers building or researching crypto products who want MCP access to Carbon Cashmere intel with automatic USDC x402 payments from EVM or Solana wallets.
When should I use x402-mcp?
During idea and early validate research when you need broad on-chain and market endpoints from the agent, before you hard-code vendor SDKs in production.
How do I add x402-mcp to my agent?
Add the @carbon-cashmere/x402-mcp stdio server in your MCP config, set EVM_PRIVATE_KEY and optional SVM_PRIVATE_KEY, and adjust X402_TOOL_LIMIT (default 100, max 177).
