Overview

The eigi.ai Claude Code plugin gives you the fastest way to use eigi.ai inside Claude Code. It bundles two pieces together:
  • The hosted eigi.ai MCP server at https://mcp.eigi.ai/mcp
  • The eigi:conversation-rules skill for prompt-writing guardrails
Use the plugin when you want Claude Code to access eigi.ai tools and prompt rules from a single installation flow.

MCP Server reference

See the full MCP server guide, supported clients, and available tool categories.

What the plugin includes

ComponentWhat it does
eigi plugin manifestRegisters the plugin in Claude Code
Hosted MCP serverConnects Claude Code to eigi.ai agent, prompt, chat, call, and provider tools
eigi:conversation-rules skillAdds reusable prompt-writing rules for speech-safe, multilingual voice agents
Behind the scenes, the plugin bundles the Claude Code plugin manifest, the hosted MCP server connection, and the eigi:conversation-rules skill into one install flow.

​
Prerequisites

  • Claude Code installed locally
  • An eigi.ai account
  • Browser-based authentication for the hosted MCP server when Claude Code prompts for it

​
Install from the GitHub repo

Use this path to install the public plugin directly from the GitHub repository. 
https://github.com/eigi-ai/eigi-plugins
In Claude Code or Claude Desktop:
  1. Open Plugins.
  2. Choose the option to add a plugin from a GitHub repository.
  3. Paste https://github.com/eigi-ai/eigi-plugins.
  4. Finish the install flow.
After installation:
  1. Start or restart Claude Code.
  2. Run /mcp to confirm the eigi server is available.
  3. Use /eigi:conversation-rules when writing or revising prompts.

​
Load the plugin locally for development

Use this path when you want to test changes from the plugin repository directly. 
git clone https://github.com/eigi-ai/eigi-plugins.git
cd eigi-plugins
claude plugin validate .
claude --plugin-dir .
Inside Claude Code, reload components if needed: 
/reload-plugins
Then verify both parts of the plugin: 
/mcp
/eigi:conversation-rules

​
Using the bundled skill

The eigi:conversation-rules skill is designed for prompt-writing and prompt review work. Use it when you want Claude Code to enforce rules such as:
  • Speech-safe plain-text output for voice and TTS channels
  • Hindi in Devanagari and English in Latin script
  • Natural Hinglish with Hindi words in Devanagari and English words preserved in Latin script
  • Preservation of exact IDs, URLs, commands, code, and user-provided literals
This is especially useful when you are creating or auditing prompts for multilingual voice agents.

​
When to use the plugin vs MCP only

Use the plugin if you are working in Claude Code and want:
  • The eigi.ai MCP tools
  • The bundled prompt skill
  • A single install path that keeps both together
Use the standalone MCP setup if you want to connect from other MCP-compatible clients such as Cursor, VS Code, Windsurf, Claude Desktop, or ChatGPT.

​
Use eigi.ai in Claude Desktop and other clients

Use the plugin install flow in Claude Code and Claude Desktop. For other AI tools, connect to the hosted MCP server directly.

​
Claude Desktop

To add the plugin in Claude Desktop:
  1. Open Customize.
  2. Go to Plugins.
  3. Click Add a GitHub repo.
  4. Paste https://github.com/eigi-ai/eigi-plugins.
  5. Finish the install flow so the plugin is added to Claude Desktop.
After installation, open Claude and complete authentication if the MCP connection prompts for it.

​
Claude.ai web app

For Team or Enterprise plans:
  1. Open Settings.
  2. Go to Integrations.
  3. Click Add more.
  4. Set the integration name to eigi.ai.
  5. Set the integration URL to https://mcp.eigi.ai/mcp.

​
Cursor, VS Code, and Windsurf

These tools also connect through the same MCP server URL: https://mcp.eigi.ai/mcp.
  • Cursor: add an MCP server in Settings.
  • VS Code: run MCP: Add Server and use npx mcp-remote https://mcp.eigi.ai/mcp.
  • Windsurf: add a custom MCP server with the same remote URL.
For the full per-client setup steps, see MCP Server.

​
Notes

  • The plugin uses Claude Code’s remote HTTP MCP transport to connect to https://mcp.eigi.ai/mcp.
  • If the plugin later needs custom authentication headers, the repository can add userConfig in .claude-plugin/plugin.json and reference it from .mcp.json.
  • The current plugin scaffold does not include Claude Code agents or hooks yet.
