Overview

AI-generated overview

Remote MCP server that verifies Bitcoin addresses, PSBTs and BIP380 descriptors, with a WorkSats credit system to earn and spend access.

What you can do
  • Check Bitcoin addresses, PSBTs and BIP380 descriptors for validity
  • Earn bearer credits by fetching a WorkSats task and submitting its solution
  • Spend credits on verification calls by passing a credit token
  • Split or transfer credits to other bots
When to use it
Useful when an assistant needs to sanity-check Bitcoin addresses, partially signed transactions or output descriptors, or when a wallet-less bot wants to earn access credits by solving tasks instead of paying.
Requirements
A remote streamable HTTP endpoint; no package, account, API key or header is declared. Credits are obtained through the WorkSats task flow and passed as a credit token.
Before you install
The server explicitly warns never to send private keys or seed phrases. Credits are bearer tokens that can be spent or transferred, so treat them as sensitive. Verification calls consume credits earned through task solving.

Installation

In SourceWeft

  1. Open Bitcoin PSBT, Address & Descriptor Verifier + WorkSats L402 MCP in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/dev.workers.jeffpersons.botcheck%2Fbitcoin-psbt-descriptor-l402-worksats/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows
