reticle setup mcp registers the Reticle MCP server with the coding agents on this machine, so the reticle_* tools are there the next time each one starts. It is the registration half of the installer, and you rarely need to run it yourself.
No flags, and nothing is asked. It works for your user account, not for one project, so it does not touch your app. To wire an app, run reticle init.
What it prints
One line per agent: ✓ <agent> for a new registration, ✓ <agent> (already set up) when Reticle was there already, and ⚠ <agent>: … when a registration failed. If it finds no agent, it names every agent it looked for.
How you know it worked
Restart your coding agent. An agent reads its server list only when it starts. After the restart, the reticle_* tools are listed.
Codex CLI keeps a TOML config that Reticle does not rewrite. For Codex, the installer and init print the lines to paste instead.Last modified on October 8, 2026
