How many blockchains are supported?

The server supports data from 48 blockchains.

3

What tools are provided?

Thirteen tools are available, including ENS domain resolution, blockchain detection, latest block, fees, mempool events, block/address/transaction overviews, and various aggregation tools.

4

How do I install and configure the server?

Clone the repository, create a `uv` virtual environment, install dependencies, then add the MCP configuration to your client’s `mcpServers` section with the correct path to the Python script and your API key (or leave empty for sandbox).

5

What if the MCP server doesn’t start?

You may need to provide the full path to `uv` in the `command` field of the MCP configuration.
