Living Brief by SquareMCP

Your work follows you across every AI agent

Keep customer and project history, decisions, mistakes, and next actions in an Obsidian Living Brief that works across ChatGPT, Claude, Codex, browser, app, and CLI.

Start with one shared brief

A Living Brief gives every connected AI the durable context needed to continue the same work. The note lives in your Obsidian vault, where you can inspect, edit, and keep it independent of any single model.

Living Brief

Connect ChatGPT to your vault and carry decisions and next actions across agents.

Communications

Draft and approve LinkedIn, Facebook, Instagram, and email content from one chat.

Connect another agent

Add SquareMCP to Claude, Codex CLI, or another MCP client.

Platform guides

Connect LinkedIn, TikTok, and WhatsApp. Step-by-step setup for each platform.

Agent tutorial

Real code: a Claude agent that researches news and posts to LinkedIn automatically.

Full SquareMCP kit

Connect communication and publishing tools when the workflow needs to act.

Remember, act, and preserve

Retrieve the brief, continue the work, use connected tools when needed, and return the outcome to the vault. This keeps the record useful for the next person or AI without turning one chat thread into the only source of context.
