The PR successfully implements MCP (Model Context Protocol) integrations for AI clients by packaging the unic-mcp stdio server alongside the main unic TUI. The implementation is comprehensive and well-structured:
Key Changes:
- Added plugin manifests for Codex (.codex-plugin), Claude (.claude-plugin), Kiro (plugin.json, mcp.json), and generic MCP clients (.mcp.json)
- Updated GoReleaser configuration to build and package both unic and unic-mcp binaries in archives and Homebrew
- Modified install.sh to install both binaries with proper permissions using the
installcommand - Updated Makefile to build unic-mcp locally and clean it properly
- Enhanced README.md with detailed installation and usage instructions for each supported AI client (Codex, Claude Code, Claude Desktop, Kiro)
- Added skills/unic-aws/SKILL.md with MCP server usage guidelines
- Updated docs/development.md with agent-plugin package structure guidance
- Added /unic-mcp to .gitignore
Verification:
The PR description indicates thorough testing including validation with plugin validators, MCP smoke tests, and verification of both binaries across platforms (macOS, Linux, Windows).
All changes appear to be production-ready with no blocking defects identified. The implementation follows best practices for MCP server integration and maintains consistency across different AI client ecosystems.

are usable before installing either one. Only proceed with both install
operations after validation succeeds, preventing unic from being replaced when
unic-mcp is missing.

Addressed the three packaging/documentation findings in f0413ae:
Validation: This updates the existing #342 implementation. CI and Amazon Q passed on f0413ae; Amazon Q reported no blocking issues and has no actionable inline threads. CodeRabbit marked all three original findings addressed and resolved their threads; its overall review is still pending. The PR remains open. |

Requested Amazon Q review for f0413ae. It completed successfully with no blocking findings or actionable inline threads. |

This PR successfully adds MCP integration for AI clients by distributing the unic-mcp stdio server alongside the main unic TUI. The implementation is thorough and well-executed:
Strengths:
- Comprehensive build system updates across Makefile, GoReleaser, and install scripts ensure both binaries are properly packaged and distributed
- Atomic installer validation prevents partial installations by checking both binaries exist before replacing either one
- Extensive documentation updates cover Homebrew, install script, source builds, and client-specific setup for Codex, Claude Code, and Kiro
- Test coverage added for installer validation logic with multiple edge cases
- Plugin manifests follow the Agent Plugins standard format for portability
Implementation Quality:
- The installer properly uses
install -m 0755for explicit permission setting - GoReleaser configuration cleanly separates build and archive configurations for both binaries
- Documentation correctly emphasizes keeping AWS credentials in the standard credential chain rather than MCP configuration
- All changes maintain backward compatibility and follow the project's existing patterns
The verification steps confirm builds, packaging, and plugin validators all pass. No blocking issues identified.
You can now have the agent implement changes and create commits directly on your pull request's source branch. Simply comment with /q followed by your request in natural language to ask the agent to make changes.

[P2] Forward the AWS environment in the Codex adapter — .mcp.json:4–6
This server configuration has no
env_vars. Codex builds an allowlisted environment and clears the inherited environment before launch; its defaults exclude AWS variables andXDG_CONFIG_HOME. If Codex is launched with shell-exported temporary AWS credentials and no on-disk credentials, MCP initialization succeeds butlist_backup_vaultscannot authenticate. DroppingAWS_PROFILEcan instead select the default AWS identity. The direct registration instructions at README.md:164–165 produce the same configuration. Add explicit variable-name forwarding through Codex'senv_varsfor the supported AWS credential/profile/config-location variables and unic's config location, and document the equivalent direct-registration configuration. Keep credential values out of the manifests and verify forwarding with dummy environment values in a client-launch smoke check.

Addressed the Codex environment review in d2ef000.
Validation: This bounded follow-up addresses the human review on #342's existing PR. The two newly posted CodeRabbit findings concerning source-build PATH instructions and installer-test timeout remain open for a separate follow-up. The PR remains open pending further review and checks. |
