Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified the GitHub account daedalus for this listing. That does not show the account is the product's maker.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

An MCP server that exposes the python-bitcoinlib API so an assistant can generate Bitcoin keys and addresses, build and sign transactions, and work with…

What you can do: It wraps the python-bitcoinlib library and exposes Bitcoin tools to an assistant. The tools cover key management (generating private keys, converting between WIF and hex), address generation (P2PKH, P2SH, P2WPKH, P2WSH), transaction building and signing, script parsing and creation, and cryptography such as SHA256, RIPEMD160, Hash160, Hash256, and ECDSA signing and verification.
When to use it: Use it when an assistant needs to work with Bitcoin primitives locally: deriving addresses, converting key formats, constructing or signing transactions, or inspecting scripts and hashes. It is aimed at Bitcoin development and experimentation rather than general blockchain data lookups.
Requirements: A local Python environment with the mcp-python-bitcoinlib package installed from PyPI (pip install mcp-python-bitcoinlib). It runs as a local stdio process, so it is configured in a desktop MCP client such as Claude Desktop. No accounts, API keys, environment variables, or headers are declared.

Before you install

The server handles private keys and transaction signing, so any key material passed to it should be treated as sensitive and kept out of shared logs or transcripts. Signing and transaction-building tools can produce data that, if broadcast, moves real funds; verify outputs before use. No credentials or network access are declared.

Installation

In SourceWeft

Open Mcp Python Bitcoinlib in the dashboard and add it to a workspace.
Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.
