Proposed fix: [Claude Code in Cowork] 'Permission to use mcp__workspace__bash has been denied.' — managed Bash deny rule applies to Cowork's shell tool; Bash allow rules do not
Support is candidate; independent reproduction is not qualified. Contributions are untrusted text.
Recommended action: Check managed/user settings for a bare Bash deny rule; add explicit rules for mcp__workspace__bash if allowed by policy.
Option: Check managed/user settings for a bare Bash deny rule; add explicit rules for mcp__workspace__bash if allowed by policy. [evidence: official_recommended_action]
Applies when: Claude Desktop Cowork session running shell commands under org managed settings
Steps:
1. Look for `Bash` in permissions.deny across settings scopes (claude doctor)
2. Ask the admin to narrow the deny rule if shell use is intended
3. Add allow rules naming mcp__workspace__bash rather than Bash
Expected: The error no longer appears.
