List regression baselines

regression.list_frozenReadsOnly looks things up; never changes your workspace.

What it does

Lists every frozen test run (regression baseline) in the connected workspace, most recently frozen first. A baseline is a run whose tests must keep passing: every later pdlc.verify fails if any of them is missing or not passing. Use it before a release, when a verdict shows frozenRegressions, or before regression.unfreeze_run. Returns count and items with id, name, gitSha, branch, workingTreeClean, frozenAt, frozenBy and caseCount (all recorded cases in that run). Read-only; takes no parameters.

Ask your agent

You don’t call regression.list_frozen yourself. Say something like this to Claude Code, Cursor or another MCP-connected agent:

  • “Which tests are locked in as must-stay-green?”
  • “Why does the verdict say something regressed? Show me the baselines”

Inputs

None. The agent calls it with an empty object.

The MCP call

What the agent’s MCP client sends (placeholders in angle brackets):

{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "regression.list_frozen",
    "arguments": {}
  }
}

Connect your agent

npx -y @testmaze/mcp init tmt_xxx
claude mcp add tm --scope project -- npx -y @testmaze/mcp

Create the token in your Test Maze workspace under Settings → MCP. Setup for Cursor, Cline, Gemini CLI and Codex CLI is shown there too.
