Install ai-architect-mcp-codebase for Codex

Installs for the current user
codex plugin marketplace add cdeust/ai-architect-mcp-codebase
codex plugin marketplace upgrade ai-architect-mcp-codebase
codex plugin add ai-architect-mcp-codebase@ai-architect-mcp-codebase

Paste and run these commands in a terminal with Codex. They add and refresh the ai-architect-mcp-codebase catalog, then install this plugin.

Compatibility: the page URL and API slug “ai-architect-mcp-codebase-2” remain stable.

  • Codex: ai-architect-mcp-codebase-2@agent-plugin-marketplace → ai-architect-mcp-codebase@ai-architect-mcp-codebase

The installer fetches third-party code from the source repository shown on this page. This directory validates manifest structure and source location, but does not perform a security audit; review the manifest, components, and source before installing.

Get the source manually

Included Skills3

impact-analysisskills/impact-analysis/SKILL.md

Trace the structural blast radius of a proposed or actual code change with ai-architect. Use for implementation planning, pull-request review, regression analysis, dependency checks, or identifying callers, importers, users, communities, and processes affected by a symbol or diff.

understand-codebaseskills/understand-codebase/SKILL.md

Build an evidence-backed map of an unfamiliar repository with the ai-architect code graph. Use before implementing a feature, debugging an unfamiliar subsystem, explaining architecture, or making structural claims about symbols and dependencies.

validate-change-planskills/validate-change-plan/SKILL.md

Check whether a proposed implementation plan matches the current code graph. Use before coding or approving a plan that names files, symbols, dependencies, boundaries, or expected blast radius; this is structural plan validation, not full PRD or semantic correctness verification.
