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.
