A collection of Bitcoin SV (BSV) tools for the Model Context Protocol (MCP) framework
Bsv MCP MCP server exists for a simple reason — assistants are far more useful when they can act on Bsv MCP directly instead of describing what you should do. A collection of Bitcoin SV (BSV) tools for the Model Context Protocol (MCP) framework.
A collection of Bitcoin SV (BSV) tools for the Model Context Protocol (MCP) framework. This library provides wallet, ordinals, and utility functions for BSV blockchain interaction.
Once Bsv MCP is connected, these are the calls the assistant has available:
Args — - data (string, required): The data string to be convertedReturns — The converted data as a stringwallet_getPublicKey — Retrieves a public key for a specified protocol and key IDwallet_createSignature — Creates a cryptographic signature for the provided datawallet_verifySignature — Verifies a cryptographic signature against the provided datawallet_encryption — Combined tool for encrypting and decrypting data using the wallet's cryptographic keys. Examples: 1. Encrypt text: "Encrypt this message: Hellowallet_getAddress — Returns a BSV address for the current wallet or a derived pathwallet_sendToAddress — Sends BSV to a specified address (supports BSV or USD amounts)wallet_purchaseListing — Purchases NFTs or BSV-20/BSV-21 tokens from marketplace listingswallet_createOrdinals — Creates and inscribes ordinals on the BSV blockchainbsv_getPrice — Gets the current BSV price from an exchange APIbsv_decodeTransaction — Decodes a BSV transaction and returns detailed informationYou will need 3 environment variables: PRIVATE_KEY_WIF, IDENTITY_KEY_WIF, YOUR_ACCESS_TOKEN. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
**Use Bun (Optional but recommended) This project is built using Bun, a fast JavaScript runtime and package manager. While Bun is recommended for best performance, the server can also run with Node.js and npm as Bun is designed to be backward compatible with node.
Being a remote server, there is no local install. You register the endpoint with your client, authorise it once, and the tools appear.
Plenty of developer tooling servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Bsv MCP's toolset — Args, Returns, wallet_getPublicKey and 11 more — is a fair guide to whether it matches your workflow. It is maintained by b-open-io; worth a glance at recent repository activity before you build anything load-bearing on it.
We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.
| Tool | What it does |
|---|---|
| Args | - data (string, required): The data string to be converted. |
| Returns | The converted data as a string. |
