Blockchain Query MCP

Blockchain Query MCP retrieves Bitcoin chain and network information using Blockchain.com’s public query interfaces.

Bitcoin reference data

The server queries Bitcoin blocks, transactions and addresses and exposes network statistics through MCP. Documented operations include balances, difficulty, block count, hash rate, latest block hash and unconfirmed transaction counts. This is a read-oriented data integration; it does not establish wallet custody or transaction signing.

Local and HTTP transports

The Python project documents a default stdio launch through main.py and an SSE mode with a configurable port. Install the repository’s dependencies in a virtual environment, then choose the transport supported by the client. A locally launched SSE listener is not a public hosted endpoint supplied by Blockchain.com.

Verify identifiers and units

For an address or transaction lookup, check the requested Bitcoin identifier before calling the tool. Compare a returned value with the source response, including its unit and observation time. Network and market statistics can change between requests, so preserve the original response when using it in an analysis.

Useful first trial

Retrieve a known transaction and a block reference, then request a network statistic. Check not-found and network-error behaviour as well as successful responses. The project’s documentation notes generated code; review and test the integration in your environment before depending on it for an operational workflow. The profile describes verified capabilities from the repository rather than a claim of independent runtime testing.
