crewpay-mcp

crewpay-mcp

MCP server for CREW / CrewPay — discover Autohire, then build unsigned launches on Pump.fun, Bags.fm, Zora, and Clanker (Base) with on-chain fee-shares (60% KOL crew / 15% launching agent / 25% treasury). Pump.fun requires a caller-generated mintPubkey and returns create + lock with signTogether: true (sign in one signAllTransactions, or one atomic-v0 tx when it fits). Fees lock at launch. crew_wire_fees is repair-only for older launches or a failed lock.

Official MCP Registry: io.github.fxams/crewpay-mcp · hosted remote https://mcp.crewpay.dev/mcp

Works with Cursor, Claude Desktop, Claude Code, ChatGPT MCP, Gemini / custom MCP clients, and any MCP client.

Remote HTTP MCP

cd agent/crew-mcp
CREW_MCP_HTTP=1 npm start
# → http://localhost:3333/mcp
# discovery → http://localhost:3333/.well-known/mcp.json
# HTTP defaults to publicMode (require x-crew-api-key). Opt out: CREW_MCP_PUBLIC=0

Production: https://mcp.crewpay.dev/mcp · https://mcp.crewpay.dev/.well-known/mcp.json
Public mode: pass x-crew-api-key for writes. Cannot launch with your wallet on the shared host — use local stdio or REST.

Env

Variable	Required	Purpose
CREW_AGENT_API_KEY	writes (private)	Server agent key (or pay with x402)
CREW_LAUNCHER_KEY	launch/wire/lock/crank	Solana secret in env only
X402_EVM_PRIVATE_KEY	no	Optional hex key — pay per call with Base USDC (x402) instead of an API key. Local env only.
CREW_API_URL	no	Default https://api.crewpay.dev
CREW_MCP_HTTP	no	1 for Streamable HTTP
CREW_MCP_PUBLIC	no	Default on for HTTP; set 0 to use shared env keys

Notes

• Descriptions: user ≤204 chars; appends Launched from CrewPay.dev platform (final ≤240).
• Canonical site: https://crewpay.dev.
• x402: when the API has X402_ENABLED, local MCP with X402_EVM_PRIVATE_KEY pays USDC on Base; the API also accepts Solana USDC when X402_SOLANA_PAY_TO is set (sign PAYMENT-SIGNATURE yourself or use another client). Hosted MCP never uses a shared x402 wallet. Fee map remains 60% to the KOL crew, 15% to the launching agent, 25% to the treasury.
