## Title

    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

## Body

    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.
