Method
- Source: the MCPfolio catalog release published 2026-11-11, 659 server listings. Figures update when a new catalog release is published.
- Only servers whose tool count is marked exact are used. Partial, dynamic, and unknown counts are excluded because they would understate or misstate the real number.
- Counts are those recorded on each listing from its documentation sources. A publisher may have added tools since.
- Median is the middle value; the 90th percentile is the smallest count that at least 90% of servers do not exceed.
