Server Details

Linear MCP — wraps the Linear GraphQL API (OAuth)

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 36 tools

Disambiguation1/5

The server mixes two entirely different domains (Linear issue tracking and the Pipeworx data-routing platform) under one name, and within the Pipeworx half there are numerous near-duplicate tools: ask_pipeworx, ask_pipeworx_beta, and ask_pipeworx_grounded are explicitly described as identical routers with only minor variations; deep_research overlaps heavily with ask_pipeworx; and three separate Polymarket edge tools (polymarket_edges, polymarket_arbitrage, polymarket_edge_tracker) are difficult to distinguish at a glance. An agent cannot reliably tell which tool to use for a given query.

Naming Consistency2/5

Naming is inconsistent across the set: the Linear tools use a consistent linear_ prefix, but the Pipeworx tools use ad-hoc names (ask_pipeworx, bet_research, compare_entities, deep_research, forget, recall, remember, subscribe) rather than a single verb_noun or domain-prefixed convention. The mix of snake_case is uniform but the semantic pattern is chaotic, with a few tools (forget, remember, subscribe, unsubscribe) forming a small consistent verb group while others do not.

Tool Count2/5

36 tools is excessive for a single server, especially when it appears to bundle two unrelated domains (Linear issues and the Pipeworx data platform). Several tools are redundant or variant duplicates (ask_pipeworx vs ask_pipeworx_beta vs ask_pipeworx_grounded, three Polymarket edge scanners), suggesting the set has grown without pruning.

Completeness2/5

The Linear portion is notably incomplete: it offers linear_create_issue, linear_get_issue, linear_list_issues, linear_list_teams, and linear_search, but no update, delete, or comment operations, so agents cannot close, edit, or discuss issues—a major gap for an issue-tracking integration. The Pipeworx portion is broad but overlaps heavily and leaves lifecycle gaps such as no clear create/update path for some data resources, making the overall surface uneven.
