B3.1/5.0

Scored 2026-04-18 11:20 across 1 tool

Disambiguation5/5

With only one tool, there is no possibility of ambiguity or overlap between tools. The tool's purpose is clearly defined and distinct by default.

Naming Consistency5/5

A single tool inherently has perfect naming consistency, as there are no other tools to compare it against for patterns or conventions.

Tool Count2/5

One tool is too few for a server named 'MCP Substack Server', which implies broader Substack functionality. It feels thin and under-scoped, lacking operations like listing posts, subscribing, or managing content beyond downloading.

Completeness2/5

The tool surface is severely incomplete for a Substack domain. It only supports downloading posts, missing core operations such as creating, updating, deleting posts, or interacting with subscribers, comments, or analytics.
