Server Details

Lichess MCP — public read-only API for users, games, explorer, tablebase.

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.

TDQS

B3.3/5.0

Scored across 41 tools

Disambiguation3/5

Descriptions are unusually detailed and often explicitly route between tools, but there are dense overlapping clusters: ask_pipeworx / ask_pipeworx_beta / ask_pipeworx_grounded / deep_research all answer routed questions, and bet_research / polymarket_arbitrage / polymarket_edges / polymarket_edge_tracker / polymarket_fill_risk / polymarket_kalshi_spread all cover prediction-market analysis. The text mostly disambiguates them, but the beta tool admitting it currently matches the stable one is a clear boundary failure.

Naming Consistency3/5

Consistently snake_case and no camelCase contamination, which helps. However the pattern is mixed: some tools are verb_noun (compare_entities, validate_claim, resolve_entity, recent_alerts), others are bare nouns (leaderboards, user, users, tv_channels, tablebase, cloud_eval), so there is no single predictable convention.

Tool Count2/5

41 tools is well above the heavy threshold, and the set is a domain mismatch — a server named Lichess whose surface is dominated by Pipeworx data-gateway and Polymarket tooling, with only ~10 actual chess tools. The volume suggests two unrelated servers bundled together rather than one well-scoped surface.

Completeness2/5

Judged against the stated Lichess/chess domain, the surface is notably incomplete: there is no way to fetch a user's games, puzzles, studies, or opening repertoire, and no game/challenge lifecycle beyond TV and tablebase lookups. The generic Pipeworx meta-tooling is broad, but it does not fill the chess gaps the server name implies.
