MCP support
The MCP server offers 10 tools and handles x402 payments automatically for MCP clients. The README also lists four vision endpoints: categorization, captioning, OCR, and embeddings.
Configuration
Remote servers need no local install. Pick your client, then copy the config or install in one click.

Details
From the project READMEimg-categorize / agent-hustle
An autonomous money system: a pay-per-call vision toolbox for AI agents, plus a marketplace worker. Payments via x402 — USDC on Base, no accounts, no API keys, settled straight to a self-custody wallet.

The toolbox
| Endpoint | Does | Price |
|---|---|---|
POST /categorize | zero-shot labels + confidence, custom label sets | $0.02 |
POST /caption | one-sentence image description | $0.02 |
POST /ocr | printed-text extraction (English) | $0.03 |
POST /embed | 512-dim CLIP vector | $0.01 |
Free: GET /demo, GET /openapi.json, GET /.well-known/x402, landing page.
Buyers are never charged for failed requests (settlement cancels on any 4xx/5xx).
Architecture
- Front door (Render free tier,
INFERENCE=proxy): stable URL, x402 paywall, ~100MB RAM, no models. Auto-deploys from this repo's master. - Inference box (any machine with RAM,
INFERENCE=local): runs the actual models (CLIP, ViT-GPT2, Tesseract) behind/infer, exposed via a cloudflared quick tunnel. - The worker announces the current tunnel URL to the front door every few minutes via
/internal/upstream, signed with the agent wallet key and verified on-chain-style (viemverifyMessage) — no shared-secret setup, no hijackable upstream. - Front door offline-safe: no upstream → 503 → buyer not charged.
Run the home side
./start.sh # server (local mode) + tunnel + worker, idempotent
node src/status.js # balances, sales, listings, current URLs
The worker (every 10 min): wallet balances, ClawTasks bounty scan, Bazaar market intel, 402index listing upkeep, signed upstream heartbeat (plus a fast 4-min heartbeat timer).
Distribution
MCP server: mcp/ — 10 tools with automatic x402 payment for any MCP client.
Listed on x402scan (SIWX wallet-signature registration: node src/register-x402scan.js <url>)
and 402index (keyless, worker maintains it). PR to awesome-x402 pending. Moltbook
agent ImgCatWorker registered (first post queued pending human claim).
Wallet
Self-custody, generated locally with viem — no exchange, no KYC. Address in .env
(AGENT_ADDRESS), private key in .env (AGENT_PRIVATE_KEY, mode 600). Back up
.env — it is the money. Import into any wallet app (network: Base) to withdraw.
Ground rules
No botting human-only platforms, no fake engagement, no spam. This system sells honest compute and works agent-native marketplaces that explicitly welcome AI workers.

New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
