Forge MCP Server

@voxell/forge-mcp

An MCP server for Forge — Voxell's hosted text-embedding API. It exposes Forge to any MCP client (Claude, Cursor, Cline, Windsurf, VS Code, …) as two tools:

• embed — turn text into vectors
• list_models — list available models and their dimensions

You bring a Forge API key. The server is stateless, and Voxell does not store the text you send or the vectors it returns — only usage metadata (token counts) is recorded, for billing. It does embeddings only — no storage, no search, no RAG. Those are different products.

What you can do with it

• Add semantic search — embed your documents with input_type: "document" and each query with input_type: "query", then rank by cosine similarity.
• Build RAG — embed a knowledge base, store the vectors, and retrieve the closest chunks to ground an LLM.
• Find similar or duplicate text — embed two texts and compare their vectors.
• Cluster or classify — embed a batch, then cluster or train a classifier on the vectors.
• Shrink vector storage — set dim to truncate (Matryoshka) and trade a little accuracy for smaller, cheaper vectors.
• Straight from your editor — ask your AI agent (Cursor, Claude, …) to embed a snippet, a batch, or a file via the embed tool — no separate script.

Requirements

• Node.js ≥ 18 (tested on 20)
• A Forge API key — create one at https://dash.voxell.ai. New accounts start with 10M free tokens, no credit card.

Use it

Most MCP clients run it on demand with npx. Add this to your client's MCP config:

{
  "mcpServers": {
    "forge": {
      "command": "npx",
      "args": ["-y", "@voxell/forge-mcp"],
      "env": { "FORGE_API_KEY": "your-key-here" }
    }
  }
}

(Cursor, Claude Desktop, Cline, Windsurf, and VS Code all use this mcpServers shape.)

Tools

embed

Returns the vectors plus the model, dimension, and token count.

Default is turbo — the one you probably want. pro/ultra trade size and speed for more dimensions.

list_models

Lists the available models and their dimensions.
