Search disc golf discs, compare flight ratings, and find similar alternatives across brands.
What our measurements say
TheDiscList Public MCP is a remote MCP server published at api.thedisclist.com. It has been probed 6 times since 9/12/2026. It answered in 6 of them (100.0%), a near-uninterrupted record. Median response time is 515 ms, a delay an agent will notice. It offers a narrow, focused set of 9 tools. On the protocol side it still runs 2025-11-25 and has not moved to the newer spec.
Agent readability score
Can an LLM agent pick the right tool here — names, descriptions and parameter clarity are assessed.
Agent readability score
Strengths
- Tool names are descriptive and indicate purpose (e.g., 'search_discs', 'compare_discs')
- Parameters are well-typed with explicit required/optional flags
- Distinct use cases for ranking tools (get_weekly_rankings vs get_disc_ranking)
Weaknesses
- Some descriptions use jargon without explanation (e.g., 'weighted Euclidean flight distance')
- No documentation of error handling or input validation constraints
- Ambiguous parameter naming in 'get_flight_matrix' (brand/category/speed are optional but unclear how they interact)
find_similar_discs— 'target_brand' parameter may cause confusion if not explicitly tied to the 'disc_id'get_flight_matrix— Optional parameters lack context on how they combine for matrix generationget_market_movers— 'type' parameter description doesn't clarify valid values (e.g., 'risers', 'fallers')

Advice
Schema compliance
tools/list structure, inputSchema validity, and a functional smoke test — the components of the 0-100 score.
- tools/list schema valid
- inputSchema is valid JSON Schema
- Smoke test not run this round
- Cold-start: cold 42ms → warm 42ms (penalty 0ms)
