# Get Mcp Harnesses

`GET /user/mcp/harnesses`

## Request

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

Every harness the caller has connected to Traversal MCP from.

The organization and user are always the caller's. Harnesses come from
self-reported client names, and unrecognized or missing names read as Other.

## Response `200`

Successful Response

- McpUserHarnessesResponse: Every harness the caller has used to connect to Traversal MCP.
  - `harnesses` McpHarness[], required: Each harness once, in McpHarness order. All time.
  - `stream_cursor` integer, nullable, required: Highest seq on this user's harness stream. Null when nothing was published. Pass it as the stream_data cursor when opening the websocket. Each event carries the raw client_name; refetch this endpoint for harness labels.
