Install MCP

CURB's portable unit is the remote MCP URL. Point any MCP client at it — no private keys, no ACCESS_KEY.

MCP: https://api.curb.numetal.xyz/mcp

Tools: swap_list_offers · swap_create_offer · swap_create_intent · swap_get_match · swap_pay_challenge

Payment signing stays in pay MCP or agentcash. CURB does not sign.

Demo harness (pitch only)

Demo / reference — not the product path. Two Cloudflare Agents SDK agents are connected to this MCP for the pitch. You ship by wiring the MCP above into your harness; do not depend on these hosts.

Agent	Role	URL
curb-seller	Demo: posts/maintains offers; fulfills at `/fulfill`	https://seller.curb.numetal.xyz
curb-buyer	Demo: lists, intents, pay challenges	https://buyer.curb.numetal.xyz
Hub	Demo pitch foyer	https://harness.curb.numetal.xyz

Both call addMcpServer('curb', 'https://api.curb.numetal.xyz/mcp') — copy that into your agent. Payment signing stays in pay MCP / agentcash — not inside the agents. Full walkthrough: Use the live harness · Harness agents.
