@bsvkey/inference-mcp

An MCP server that lets any agent buy Claude & Grok inference metered per token, settled in BSV, through the hosted gateway at inference.bsvkey.com. Zero dependencies (Node ≥ 18, uses global fetch). It's a thin HTTP client — it never holds your keys or runs models; every call is billed through the gateway.

Tools: list_models, infer, channel_balance, open_channel.

Quick start

1. Fund a channel once at https://inference.bsvkey.com (BRC-100 wallet, or load a key in-page). Copy the key it returns: channelId:channelSecret.
2. Add the MCP server to your agent host (below), with that key in BSVKEY_API_KEY.
3. Ask your agent to run inference — it calls infer and pays per token.

list_models and open_channel work with no key; infer and channel_balance need a funded channel key.

Install

Published on npm as @bsvkey/inference-mcp.
