"""Tests for MCP config secret masking and preservation.
|
|
|
|
Verifies that GET /api/mcp/config masks sensitive fields (env values,
|
|
header values, OAuth secrets) and that PUT /api/mcp/config correctly
|
|
preserves existing secrets when the frontend round-trips masked values.
|
|
PATCH /api/mcp/config coverage pins targeted state changes, raw-config
|
|
preservation, transport aliases, authorization, and command validation.
