Web & App Connections
Codebase connection guidance is organized into three paths: official web and app instructions, API key based MCP setup, and the SKILLS installation flow.
Overview
Codebase connections are grouped into three practical paths. First, you can connect directly inside web and app surfaces such as ChatGPT, Claude, or Perplexity. Second, you can issue an API key and register MCP through a config file or CLI command. Third, you can install SKILLS for a faster shared onboarding flow.
Web & App Connections
This section covers the web and app environments users interact with directly, such as ChatGPT, Claude, and Perplexity. Each guide is aligned to official documentation, and the screenshots are wired so replacing files under frontend/public/docs/apps/... updates the page automatically.
ChatGPT
A step-by-step guide to finding and connecting the Codebase app inside ChatGPT, based on OpenAI’s official apps documentation.

Perplexity
Perplexity does not currently document a confirmed end-user flow for connecting an external remote MCP server such as Codebase inside the Perplexity web or mobile app. This page is a verification checklist rather than a finished setup guide.

Claude
A guide to adding a custom connector via remote MCP in claude.ai and then using it across the web and mobile apps, based on Anthropic’s official support docs.

API Keys & MCP
This path issues an API key and registers the hosted MCP endpoint directly in each client. The docs mirror the key management, client selection, copy, and restart flow shown in Auto-publishing connection.
API key management
Manage up to 3 keys with 90-day expiration plus usage, expiry, and last-used history.
Direct MCP setup
Follow the Select → Copy → Restart flow for Codex, Claude Code, Gemini, Cursor, and related environments.
Operational checks
The guide also covers endpoint validation, expired keys, config formats, and Codex-specific rules.
SKILLS
This path installs the Codebase skill so Codex, Claude Code, Gemini CLI, and Antigravity can share the same onboarding flow. It repackages the `SKILLS install` and `LLM Agents install` sections from settings as documentation.
Global install
Install multiple agents globally in one pass and reuse the same skill source across them.
Per-agent install
Install only the environments you need, such as Codex, Claude Code, Gemini CLI, or Antigravity.
LLM agent guidance
Includes the fetch-based path for letting an agent read the installation guide and follow the process.
