Blockchain MCP servers retrieve chain data or connect assistants to supported wallet and contract tools. They can help inspect a transaction, read a contract state or query an indexer. Transaction signing is a separate capability that not every server exposes.
Compare network support, address formats and whether the tools read data or submit transactions. Look at the indexer’s freshness when using historical results. A blockchain integration can also appear under finance when it provides market or portfolio data.
Browse the servers below for available tools, connection options and links to the maintainer’s documentation. A server can belong to several categories when it supports several kinds of work.
