    C2.6/5.0

    Scored across 224 tools

    Disambiguation2/5

    Many tools have overlapping purposes, especially the legacy/undocumented endpoints that duplicate official ones (e.g., multiple search tools, multiple file upload variants). The sheer number of tools makes it difficult for an agent to select the correct one.

    Naming Consistency4/5

    Tool names follow a consistent snake_case verb_noun pattern (e.g., conversations_list, files_upload). Minor deviations exist, such as 'slack_lists_*' prefix and 'v2' suffixes, but overall the naming is predictable.

    Tool Count1/5

    224 tools is excessively high for a single MCP server. While Slack has a large API, many tools are undocumented session endpoints or legacy methods, leading to bloat. The set would benefit from trimming to essential, well-documented tools.

    Completeness4/5

    The server covers a wide range of Slack functionalities (channels, messages, files, users, search, workflows, apps). Minor gaps exist (e.g., no enterprise grid or modern admin user management), but overall it is very comprehensive.
