Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@focal-mcp fetch the current AI behavior rules"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
FOCAL MCP (Framework for Orchestrated Central AI ruLes) is a local MCP server that centralizes AI behavior rules and applies them across tools like Codex, Claude Code, and Cursor.

FOCAL MCP uses streamable HTTP, so you start the server yourself and point clients to the URL above.
Add the following to ~/.codex/config.toml:
[mcp_servers.focal]
enabled = true
url = "http://127.0.0.1:8765/mcp"Restart Codex after saving.
Rules live outside the repo in:
~/.focal_mcp/workspace/

FOCAL MCP exposes a tool named focal_rules. Agents should call it before every response to fetch the latest rules.
If rules do not update immediately:
Ensure the client is connected to the MCP server.
Ensure the client calls focal_rules before responding.
Reconnect the client if needed.
The repository-level prompt is stored in:
agents.mdProject-specific rule management for multi-repo workflows
UI/UX improvements for rule editing and visibility

Research-backed linting + generation for agent context files (CLAUDE.md, AGENTS.md, Cursor rules).
Persistent cross-session memory shared by Codex, Claude Code, ChatGPT, and other AI agents.
