Method
- Source: the MCPfolio catalog release published 2026-11-11, 659 server listings. Figures update when a new catalog release is published.
- Covers the 630 servers whose individual tools are listed in the catalog. A server with only a partial tool list contributes only the tools that are listed.
- Tool names are compared in lowercase. Servers that list a tool with the same name are counted together, even though the tools may behave differently.
- Each tool is assigned an action by the first verb recognised in its name (for example get, list, create, delete, send, run). 2,532 tools have no recognisable verb and are left out of the action shares. A tool named for one action can still do more than its name says.
- “Write-capable” means a server lists at least one create, update, delete, or send tool. Execute-type tools are shown separately and are not counted as write-capable.
