Returns 409 if another live environment took its name in the meantime. Plugin pins whose version row no longer exists at all are dropped on the way back to live — compare the returned `pluginVersionIds` against what you archived to detect that. Requires `expectedRevision` — the revision you last read. If the environment changed since, the write is rejected with 409 rather than overwriting the concurrent edit. Requires project admin. ## OpenAPI ````yaml /reference/openapi.json post /projects/{projectId}/environments/{environmentId}/restore openapi: 3.1.0 info: title: MCPJam API version: 1.0.0-preview description: >- Programmatic access to MCP servers saved in your MCPJam projects — live diagnostics (validate, inspect, export) and operations: call tools, render prompts, run eval suites asynchronously and poll their results, and import OAuth tokens. **The API is in preview**: the surface may change while we finish the design. Error `code` values are stable; error `message` strings are not.
