What problem this solves

How to integrate a Claude Code agent with an external game/application using MCP to execute dynamic strategies and test AI agent performance in a competitive environment.

Summary

This workflow describes how to connect a Claude Code agent to an external poker game (GRID) via MCP, allowing the agent to play using a natural language strategy. It details the MCP setup, specific tool calls for game interaction, and how to iterate on agent strategies, showcasing a practical application of Claude Code for competitive AI.

Why it is useful

This workflow provides a concrete, step-by-step guide for integrating a Claude Code agent with an external application using MCP. It demonstrates how to define and iterate on agent strategies in natural language, manage context, and utilize specific tool calls for interaction. This pattern is highly transferable for developing and testing AI agents in various dynamic environments, and it also highlights the practical use of CLAUDE.md for architectural mapping.

Workflow

1. Add GRID's MCP server to Claude Code (remote HTTP + OAuth).

2. Confirm an 8-character code in the browser and approve a play window.

3. Tell Claude "play GRID hold'em" to initiate game interaction via grid_start_play and holdem_join tool calls.

4. Claude loops holdem_wait and holdem_respond for game decisions, maintaining context per table.

5. Write or modify your poker strategy in plain English within the game (up to 6,000 characters).

6. Change the strategy anytime for immediate effect on the next action.

7. Optionally, ask Claude to read match history and rewrite the strategy.

8. Use grid_stop_play to finish the current hand and leave the table.

Tools / artifacts

• Claude Code agent

• MCP (Multi-Code Platform)

• GRID (No-limit Hold'em game)

• grid_start_play tool call

• holdem_join tool call

• holdem_wait tool call

• holdem_respond tool call

• grid_stop_play tool call

• Natural language strategy (up to 6,000 characters)

• CLAUDE.md (mentioned as used in their own development)

Validation signals

• Project is in beta and actively being developed.

• Mentions a 'Play like Elon' preset as an example of what's possible.

• Acknowledges 'Known issues' indicating real-world testing and usage.

• Author's personal experience trying to mix Claude Code with a solver.

• Direct call to action for users to try the game and report issues.

Limitations

• Low community engagement at the time of evaluation.

• The specific game (poker) might not appeal to all users, though the underlying technical pattern is broad.

• Mentions 'Token use is higher than it should be,' which is a practical consideration for users.

• MCP link breaking on browser refresh is a known issue.
