eve-fit-mcp

English | Русский

MCP server for EVE Online ship fitting. Lets your AI agent pick real ship modules, validate a fit against fitting limits and compute real numbers instead of hallucinating them.

Powered by official CCP data (SDE) and live market prices.

Requirements

• Node.js 22.5 or newer (any current LTS is fine)

• git

• Any MCP-capable agent: OpenCode, Claude Code, Codex, etc.

Install

The easy way: let your agent do it

Paste this into your agent:

Install the MCP server from https://github.com/remandorsn/eve-fit-mcp:
1. git clone https://github.com/remandorsn/eve-fit-mcp.git ~/eve-fit-mcp
2. cd ~/eve-fit-mcp && npm install && npm run build
3. Register it as a local MCP server named "eve-fit" in your own config:
   command: node, args: [~/eve-fit-mcp/dist/index.js]  (use the absolute path)
On first start the server downloads the EVE SDE (~100 MB, a few minutes) automatically.
After that, verify it works by searching for "Rifter" via eve_search_items.

Manual setup

git clone https://github.com/remandorsn/eve-fit-mcp.git
cd eve-fit-mcp
npm install
npm run build

Note: on first start the server downloads and imports the EVE SDE into data/ (~100 MB download, a few minutes). You only do nothing — it happens by itself. To refresh data after a game expansion, run npm run sde:update.

Then point your client at node <path-to-repo>/dist/index.js:

OpenCode

opencode.json in your project (or global config):

{
  "mcp": {
    "eve-fit": {
      "type": "local",
      "command": ["node", "/absolute/path/to/eve-fit-mcp/dist/index.js"]
    }
  }
}

Claude Code

claude mcp add eve-fit -- node /absolute/path/to/eve-fit-mcp/dist/index.js

or a .mcp.json in the project root:

{
  "mcpServers": {
    "eve-fit": { "command": "node", "args": ["/absolute/path/to/eve-fit-mcp/dist/index.js"] }
  }
}

Codex

~/.codex/config.toml:

[mcp_servers.eve-fit]
command = "node"
args = ["/absolute/path/to/eve-fit-mcp/dist/index.js"]

Any other MCP client

The server speaks standard MCP over stdio, so any client with a JSON config works:

{ "command": "node", "args": ["/absolute/path/to/eve-fit-mcp/dist/index.js"] }

Example prompts

• «Собери фиты на Rifter под 15 млн ISK, нужно 80+ DPS»

• "Compare an Ishtar heavy-drone boat vs a VNI for Abyssal Decks, include EHP and DPS"

• "Price this Hyperion fit at Jita and tell me the cheapest alternative for the mods"

Development

npm test        # unit + integration tests of the dogma engine
npm run dev     # run the server from source (tsx)
npm run sde:update
