# List a project's hosts

`GET /projects/{projectId}/hosts`

The hosts saved in the project — the named model + capability profiles you attach to chats and eval suites. Returns the `id`s the host detail/update/delete routes take.

## Path parameters

- `projectId` string, required

## Response `200`

The project's hosts.

- HostPage
  - `items` Host[], required
    - `id` string, required
    - `name` string, required
    - `hostConfigId` string, required — ID of the content-addressed host config this host points at.
    - `modelId` string, required — Resolved model id, e.g. `anthropic/claude-haiku-4.5`.
    - `serverCount` integer, required — Number of MCP servers attached to the host config.
    - `createdAt` number, required — Unix epoch milliseconds.
    - `updatedAt` number, required — Unix epoch milliseconds.

## 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.
- `502` — Could not connect to the target MCP server.
