Glama couldn't complete the latest health check. If this server requires authentication, missing or expired test credentials may be the cause. A test profile lets Glama authenticate for health checks and discover tools; it is separate from your personal connections.

TDQS

C2.6/5.0

Scored 2026-04-18 06:26 across 56 tools

Disambiguation2/5

Many tools have overlapping purposes with unclear boundaries, such as multiple address-related tools (e.g., get_address_tokens, get_address_token_balances, get_address_token_transfers) that could confuse agents about which to use for specific queries. While descriptions provide some guidance, the sheer number and similarity in naming (e.g., get_token_transfers vs get_token_token_transfers) create significant ambiguity in tool selection.

Naming Consistency4/5

Tool names follow a consistent snake_case pattern with a 'get_' prefix for most tools, making them predictable and readable. Minor deviations exist, such as 'health_check' without 'get_' and some tools with specific prefixes like 'celestia_service_', but overall naming is largely uniform across the set.

Tool Count2/5

With 56 tools, this server is excessively large for an MCP server, likely overwhelming agents and causing confusion. While the domain (blockchain explorer) is broad, the tool count feels bloated with many similar or overlapping endpoints, suggesting poor scoping and a need for consolidation or better organization.

Completeness5/5

The tool set provides comprehensive coverage for a blockchain explorer domain, including endpoints for addresses, blocks, transactions, tokens, NFTs, smart contracts, and indexing status. It supports full CRUD-like operations (though mostly read-only as expected) and includes discovery tools, ensuring agents can access all necessary data without significant gaps.
