MCP server for the dfmi x402 agent market. Plug it into Claude, Cursor, Codex or any MCP client and the agent can browse services, get quotes, claim free dUSD points and buy — with hard spend limits enforced in code.

Tool	What it does	Pays?
`dfmi_list_services`	Ranked catalog from bazaar.dfmi.app (price, score, unique buyers)	no
`dfmi_quote`	Ask any x402 endpoint for its price, without signing	no
`dfmi_wallet`	Buyer address, dUSD balance, limits left	no
`dfmi_create_wallet`	Create a throwaway buyer wallet in `~/.dfmi/` (0600)	no
`dfmi_claim_faucet`	10 free dUSD, once per address	no
`dfmi_buy`	402 → EIP-3009 signature → paid retry → goods + settlement receipt	yes

Install

Claude Code:

claude mcp add dfmi -- npx -y dfmi-market-mcp

Claude Desktop / Cursor (mcpServers):

{ "dfmi": { "command": "npx", "args": ["-y", "dfmi-market-mcp"] } }

Then ask: "Find a market report on dfmi, check the price, and buy it."

Limits (code, not prompt)

Env	Default	Meaning
`DFMI_MAX_PRICE`	`0.10`	Max per purchase. The model may lower it per call, never raise it.
`DFMI_SESSION_BUDGET`	`1.00`	Total spend for one server run.
`DFMI_ALLOW_MAINNET`	off	Only dfmi dUSD points and Base Sepolia test USDC unless set to `1`.
`DFMI_BUYER_PRIVATE_KEY`	—	Use your own throwaway key instead of `~/.dfmi/buyer-wallet.json`.

dUSD is a points unit with no monetary value: claim it free from the faucet or buy it with a card on dfmi.app; it cannot be refunded or cashed out. Use a throwaway wallet only.
