# Mcp Telemetry

`GET /mcp/telemetry`

## Request

- Base URL: `https://api.colourmemory.com` (the document declares no server; this is the origin it was published from)
- URL: `https://api.colourmemory.com/mcp/telemetry`
- Auth: none declared

Recent MCP tool calls and what they returned. No arguments, no prompts.

ADMIN-GATED. It was readable by anyone: the rows carry no arguments and
no colour values, but they do carry every caller's User-Agent, the tools
they called, when, and how long each took -- which is a usage picture of
other people's clients, served to whoever asked. Operationally it is
worth keeping, so it is gated rather than removed.

The SAME mechanism as /admin/queries and /admin/reliability -- _admin_ok
against ADMIN_SECRET, 403 on failure -- deliberately, rather than a new
one. _admin_ok fails closed when ADMIN_SECRET is unset, so a deployment
that forgets the variable serves nothing instead of everything.

- `tool` string
- `client` string

## Headers

- `x-admin-key` string, nullable
