Ethereum Improvement Proposals (EIPs) MCP server

This MCP server provides semantic search capabilities for Ethereum Improvement Proposals (EIPs), allowing AI agents to find contextually relevant EIP documents based on natural language queries.

Features

• Semantic Search: Utilizes vector embeddings for accurate, context-aware search across EIP documents
• Markdown Support: Processes EIP markdown files with chunking for efficient storage and retrieval

Installation Requirements

Prerequisites

• Python 3.10 or higher
• uv (recommended) or pip for dependency management

Installation Steps

1. Clone the repository with submodules:

   git clone --recursive-submodules https://github.com/kukapay/eips-mcp.git
   cd eips-mcp
   

2. Install dependencies:

   uv sync
   

3. Load EIP documents:

   uv run load_eips.py
   

4. Install to Claude Desktop:

   uv run mcp install main.py --name "EIPs"
   

Configuration Reference

When installing to Claude Desktop, you'll need to configure the server. Here's a reference configuration:

{
   "mcpServers": {
       "EIPs": {
           "command": "uv",
           "args": [ "--directory", "/path/to/eips-mcp", "run", "main.py" ]
       }
   }
}

Be sure to replace /path/to/eips-mcp with your actual installation path.

Using the MCP Server

The server provides a single MCP tool called search which accepts natural language queries and returns relevant EIP content.

Example Queries

You can use natural language prompts such as:

• "Search for EIPs related to CREATE2"
• "Find EIPs about contract deployment opcodes"
• "EIPs discussing CREATE2 implementation details"

Understanding Results

The tool returns up to 5 relevant EIP document chunks, clearly separated with formatting markers. Here's an example of what results might look like when searching for "CREATE2":

--------------------eip-1014.md--------------------
# EIP-1014: Skinny CREATE2
**Abstract**: This EIP adds a new opcode at 0xf5, CREATE2, which allows for deterministic address generation...
...
--------------------eip-1014.md--------------------
**Motivation**: The CREATE2 opcode enables predictable contract addresses, which is useful for...
...

The results include section headers to show which EIP document each chunk comes from, making it easy to understand the source of the information.

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "EIPs" '{"command":"uv","args":["--directory","/path/to/eips-mcp","run","main.py"]}'

See the official Claude Code MCP documentation for more details.

For Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "EIPs": {
            "command": "uv",
            "args": [
                "--directory",
                "/path/to/eips-mcp",
                "run",
                "main.py"
            ]
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

2. Add this to your configuration file:

{
    "mcpServers": {
        "EIPs": {
            "command": "uv",
            "args": [
                "--directory",
                "/path/to/eips-mcp",
                "run",
                "main.py"
            ]
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
