What 477 MCP servers declare they can do

On 2026-09-14 we asked every server in the official MCP registry with a public endpoint to list its tools. 482 of 1,215 answered. These figures are what their manifests declare — not what the products do.

477 of 477

declare no cap, no expiry and no way to switch a tool off.

MCP has no field in which to declare any of these. A product may provide such controls outside MCP, where a manifest cannot show them.

22%

106 servers declare at least one tool that sends, deletes or moves money.

Read from each tool’s own annotations where present, otherwise from its name. Each server page shows the basis for every tool.

58%

278 servers annotate none of their tools as read-only or destructive.

95 annotate every tool. Annotations are written by the server being described, and MCP clients are told not to rely on them.

14

Servers that declare tools which move money. None declares a spending limit.

Between them, 24 tools. MCP has no field for a spending limit either.

5,322 tools across 477 servers. 169 servers declare only lookups. Of the servers with a delete, 52 marked a tool destructive themselves — MCP’s destructiveHint, which covers any destructive update, not only removal — and 24 have one named for removal.
