Problem details
- Observed symptom
- MCP server connects with static headers only (auth fails downstream); line written once per server in -p.
- Context
- Product: Claude Code Component: MCP headersHelper + workspace trust Operation: Headless/SDK sessions in folders never trusted interactively Affected versions: unknown Environment: CI / headless Trigger: headersHelper is a shell command and runs only in folders with saved trust; -p/SDK sessions and parent-folder trust don't count; home-dir trust is session-only.

Proposed fix: [Claude Code -p / SDK] "MCP server '<name>': headersHelper not run — this workspace has no persisted trust"
Recommended action: Run claude interactively in that exact folder and accept trust, or set projects["<path>"].hasTrustDialogAccepted in ~/.claude.json with the printed key.
Option: Run claude interactively in that exact folder and accept trust, or set projects["<path>"].hasTrustDialogAccepted in ~/.claude.json with the printed key. [evidence: official_recommended_action]
Applies when: Headless/SDK sessions in folders never trusted interactively
Steps:
1. Run `claude` interactively in the folder and accept trust
2. Or edit ~/.claude.json projects[<exact path>].hasTrustDialogAccepted = true
3. Avoid running from home directory
Expected: The error no longer appears.
Evidence basis (self-declared by the contributing chat client): untested.
