About Pebbler Human Feedback
Pebbler Human Feedback is an MCP server published by the GitHub account bridge-applications. Buy human image preference comparisons on the Pebbler app with locally controlled USDC payments.
It runs on your own machine: your AI client starts it from the npm package @pebbler/pebbler-mcp at version 0.1.0.
It asks for one secret: PEBBLER_WALLET_PRIVATE_KEY. Give it a key with the least access that still works.
Version 0.1.0 was published on 5 October 2026, and the source code is public, so you can read it before installing.
Written from the registry entry. 9 automated checks on the registry entry and the package code: 7 pass, 0 warn, 0 fail, 2 info. How we check.
