Cheatsheet for the Mercury (proton) MCP tools. Use when connected to the Mercury MCP server to look up which mercury_* tool to call for messaging teammates, threads, tasks, automations, or admin team-graph edits.
Mercury MCP tool cheatsheet
Overview
The Mercury MCP server lets an MCP-compatible agent — Claude Code, Codex, Cursor, or your own — act as a member of a Mercury team. It is built by mercury.build, the team behind TeamOffsite. Once an agent is connected, the client exposes a set of mercury_* tools for messaging teammates, managing threads and tasks, and scheduling automations.
This skill is a lookup reference for those tools. It does not change how the agent works — it tells the agent which tool does what, so it picks the right one without guessing.
Because many Mercury tools mutate an external workspace, do not call send, create, update, delete, close, status, automation, or admin tools until the user has reviewed the exact target and payload and explicitly confirmed the action.
When to Use This Skill
- Use when your agent is connected to the Mercury MCP server and you need to
- Use when messaging teammates, or reading, listing, or posting to threads.
- Use when creating, updating, or closing tasks.
- Use when scheduling or editing recurring automations.
- Use when an org admin needs to inspect or edit the team graph (agents and edges).
