# Uninstall a registry card

`DELETE /projects/{projectId}/registry/installs/{registryServerId}`

Card-only. Directory uninstall is `DELETE /projects/{projectId}/servers/{serverId}` — provenance is cleaned with the server.

## Path parameters

- `projectId` string, required
- `registryServerId` string, required

## Response `200`

Uninstalled.

- object
  - `deleted` boolean

## Other responses

- `401` — Missing, invalid, revoked, or orphaned key (`UNAUTHORIZED`) — or the **target MCP server** needs an OAuth grant (`OAUTH_REQUIRED`), which is a property of the server, not your key.
- `403` — Key is valid but not allowed to do this.
- `404` — Unknown project, server, or resource.
- `429` — Per-key rate limit exceeded (60 requests/minute sustained, bursts up to 10). Honor `Retry-After` and back off with jitter.
- `500` — Something failed on MCPJam's side.
