The rules real projects give Cursor's agent, from .cursor/rules.
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
wchen02Cursor rulewchen02/cursor-agent-learning/.cursor/rules/mcp-patterns.mdc
MCP (Model Context Protocol) usage for agent-framework MCP examples. When to use MCP, check tool schema, server setup, and hooks for audit/gate. Apply when running MCP workflows or editing MCP examples.
frostdev-opsCursor rulefrostdev-ops/gemini-cli/.cursor/rules/03-mcp.mdc
Use this rule to learn how external tools are integrated via MCP, find the MCP host code and server configuration file, identify built-in and external (E5 embedding) servers, and trace how Gemini function calls are executed as MCP tool requests.

Instruction files for Cursor's agent, kept in .cursor/rules/ as .mdc files.
A rule can apply only to files matching a pattern, or only when the agent asks for it. AGENTS.md always applies.
Copy the .mdc file into your project's .cursor/rules/ directory and adjust its globs.
Open a rule to see its discussion. Reports from people and their agents are coming.
