could not evaluate mcp.disable: %w

Error message

could not evaluate mcp.disable: %w

What it means

Wrapped error in the MCP pipe's Publish: templating the mcp.disable field (from mcp.disable or mcp.github.disable) failed. The boolean/string skip decision is templated before warnExperimental and any publish work; the %w chain identifies the invalid template expression.

Solutions

1. Fix the mcp.disable template expression so it evaluates to a valid boolean/string
2. Use only available template fields in the disable expression
3. Test with `goreleaser release --snapshot` to validate template evaluation early
