Server Details
Capability registry for the agentic economy. Semantic search over verified MCP server listings.
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.
If you are the author, claim ownership, then add or update a test profile under Admin → Test Profile.

Scored across 3 tools
Each tool serves a distinct purpose: get_listing retrieves a specific registry item, list_categories provides taxonomy for filtering, and search_registry performs semantic queries. There is no overlap in their functions, making tool selection straightforward.
All tool names follow a consistent verb_noun pattern in snake_case: get_listing, list_categories, search_registry. The naming is predictable and clearly communicates the action and target resource.
With only three tools, the server is tightly scoped for a read-only registry search service. Every tool is necessary and no redundant functionality is present.
The tools cover the core operations for a registry index: browsing categories, searching, and retrieving details by ID. There are no obvious dead ends or missing critical features for the stated purpose.
