This crate implements a stateless MCP endpoint that integrates with brk_server to expose BRK's Bitcoin blockchain data through a standardized protocol, enabling LLMs like Claude to directly query blockchain metrics, transaction data, market prices, and time-series data.

The stateless design makes it compatible with load balancers by default.

Tools Available

get_index_count - Count of available data indexes
get_vecid_count - Count of available vector identifiers
get_vec_count - Total count of all vectors
get_indexes - List all available indexes
get_accepted_indexes - Index types and their variants
get_vecids - Paginated list of vector identifiers
get_index_to_vecids - Vectors supporting specific indexes
get_vecid_to_indexes - Indexes supported by specific vectors
get_vecs - Query vector data with flexible parameters
get_version - BRK version information

Usage

The MCP server is automatically exposed at /mcp when BRK's HTTP server is running with MCP enabled.

With Claude Desktop
