# List run iterations

> Per-iteration results: actual tool calls, structured token usage, and latency. Cursor-paginated.

  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.
    Write clients that ignore unknown response fields.

      Project environments: named, live-editable execution bundles (one host, an
      optional standalone server group, optionally pinned skills and plugin
      versions) that eval suites and journeys run against. Distinct from Sandbox
      images, which are Computer base images. Reads require project membership;
      every write requires project admin.
