afmontoya/baconservices-mcp

An MCP server that lets an AI agent buy image work from Bacon Services,
one call at a time, paid in USDC on Base over x402 from your own wallet,
within spending limits you set. There's no account and no API key: the agent calls a tool, the
server checks the price against your limits, signs a USDC payment for exactly that price, and
returns the result.
Also listed in the MCP Registry as io.github.afmontoya/baconservices-mcp.
## Wallet safety
Your wallet private key stays on your machine. Bacon Services never receives or stores it.
Payments are signed locally and are subject to configurable per-call, session, and daily
spending limits.
## What it sells
| Tool | Does | Price (2026-10-17) |
| removebackground | Removes the background from one photo; returns a transparent PNG at the photo's size | 0.20 USDC |
| optimizeimage | Resizes so the longest side ≤ maxwidth (64–4096, default 1600) and encodes WebP at quality (40–95, default 80) | 0.01 USDC |
| imagepalette | The colours one image is mostly made of, as JSON: up to count (1–12, default 6) hex colours with their share, includeneutrals (default true) | 0.01 USDC |
| brandfromurl | Reads one public web page (url) and returns its brand as JSON: name, description, logo URLs, colours, fonts, social profiles. No JavaScript runs; robots.txt is respected | 0.03 USDC |
Image tools take PNG, JPEG or WebP up to 8 MB, as imageurl (public https) or imagepath (a
local file). removebackground and optimizeimage return a signed download link (valid 24
hours); imagepalette and brandfromurl return their JSON result in the tool result. Add
saveto to write either kind to disk. Prices come from Bacon's live catalog, and each paid tool
states its current price in its description.
imagepalette and brandfromurl appear once Bacon's catalog publishes them with contract
versions. A service the installed package doesn't understand is listed by listservices but
can't be called until you update the package.
Free tools:
listservices: everything Bacon sells right now, with prices, limits, and whether this
version of the package can run it.
quote: Bacon's current price for one service, and whether your limits and wallet allow it.
Nothing is signed.
walletstatus: network, whether a wallet is configured, your limits and what's left of them,
and whether you can afford each service (yes/no).
## Before you start
1. Node.js 20 or newer.
2. A dedicated wallet holding only what you're willing to spend. Fund it with USDC on Base.
You don't need ETH: x402 payments are signed authorizations (EIP-3009), and the facilitator
pays the gas.
3. Put the private key in a file that only you can read, for example ~/.bacon/buyer.key.
Pointing BACONWALLETKEYFILE at that file keeps the key out of MCP host configs, which are
often synced or shared. BACONWALLETPRIVATEKEY also works.
The key never leaves your machine. Only signatures are sent, and only to Bacon. The key is never
logged, never written to the spend ledger, and never accepted as a tool argument.
## Install
