OAuth 2.0 Authentication: Secure authentication with PKCE support
Multiple Transport Options: SSE (Server-Sent Events) and HTTP
Dynamic Client Registration: Automatic OAuth client registration
Full ESI API Coverage: Access to all EVE Online ESI endpoints

Installation

Installing via Smithery

To install EVE Online ESI Server for Claude Desktop automatically via Smithery:

npx -y @smithery/cli install @kongyo2/eveonlineesi-mcp --client claude

Manual Installation

npm install

Configuration

Create a .env file with the following variables:

# EVE Online ESI API Key (for ESI authentication)
EVE_ONLINE_APIS_API_KEY=your_eve_api_key

# OAuth Configuration (optional - will use defaults if not provided)
OAUTH_CLIENT_ID=eve-online-esi-mcp
OAUTH_CLIENT_SECRET=your_oauth_secret
JWT_SECRET=your_jwt_secret

# Server Port (default: 3001)
PORT=3001

Running the Server

Local Mode (stdio)

For direct local connections:

npm start

Remote Mode (SSE/HTTP)

For remote connections with OAuth:

npm run start:sse

Using with geelen/mcp-remote

To connect to this server using geelen/mcp-remote, configure your MCP client (e.g., Claude Desktop, Cursor) with:

{
  "mcpServers": {
    "eve-online-esi": {
      "command": "npx",
      "args": [
        "mcp-remote",
        "http://localhost:3001/sse"
      ]
    }
  }
}

Or if deploying to a remote server:

{
  "mcpServers": {
    "eve-online-esi": {
      "command": "npx",
      "args": [
        "mcp-remote",
        "https://your-server.com/sse"
      ]
    }
  }
}

Available Tools

The server provides access to all EVE Online ESI endpoints, including:

Alliance: Get alliance information and corporations
Character: Access character data (location, mail, wallet, etc.)
Corporation: Corporation details and history
Market: Market prices, orders, and groups
Universe: Regions, systems, structures
Killmails: Kill reports
And many more...

OAuth Flow

When connecting via mcp-remote, you'll be redirected to authorize
Approve access to grant permissions
The server will issue an access token
All subsequent requests will use this token

Transport Strategies

When using mcp-remote, you can specify transport strategies:

# SSE only
npx mcp-remote http://localhost:3001/sse --transport sse-only

# HTTP only
npx mcp-remote http://localhost:3001/mcp --transport http-only

# Try SSE first, fallback to HTTP
npx mcp-remote http://localhost:3001/sse --transport sse-first

Endpoints

SSE: GET /sse - Server-Sent Events transport
HTTP: POST /mcp - HTTP transport
OAuth:
- POST /oauth/register - Dynamic client registration
- GET /oauth/authorize - Authorization endpoint
- POST /oauth/token - Token endpoint
Health: GET /health - Health check

Development

To list all available tools:

npm run list-tools
