OfficialServer Configuration
Describes the environment variables required to run the server.
| Name | Required | Description | Default |
|---|---|---|---|
| MCP_AUTH_TOKEN | No | Bearer token for HTTP transport when bound to non-loopback. Prefer this over the --auth-token CLI argument. | |
| CRYPTOAPIS_API_KEY | Yes | Your Crypto APIs API key. Required for stdio transport and for HTTP transport in startup-key mode. Can also be supplied via the --api-key CLI argument. |
Instructions
Guidance the server publishes about itself, which clients place ahead of the tool catalog so the model reads it before choosing anything.
This server publishes no instructions, or was last inspected before Glama recorded them.

TDQS
Scored across 4 tools
Each tool is clearly scoped to a distinct blockchain family (EVM, UTXO, XRP) or system reference, with no overlap in purpose. The actions within each block data tool are identical but apply to different networks, making selection dependent on the target blockchain—a clear and unambiguous decision.
All block data tools follow the same naming pattern: {family}_block_data (e.g., evm_block_data, utxo_block_data, xrp_block_data), and the actions inside each are uniformly named (get-block-by-height, list-transactions-by-hash, etc.). system_info breaks the pattern but is logically distinct and still uses a simple noun convention.
With only 4 tools, the count is on the lower end, but each block data tool encapsulates 6 actions across many blockchains, providing substantial functionality. This is a focused server for block data retrieval, so the tool count is reasonable, though the surface could be expanded with more specific tools if needed.
The tools cover the core block lifecycle: fetching blocks by height/hash and listing transactions in blocks, plus latest block retrieval. A notable missing operation is a direct transaction lookup by hash/txid, which would be a natural addition. Overall, the surface is solid for block data but has a minor gap in transaction-level access.
