# classifier.dev docs

Connects classifier.dev reference manuals, benchmarks, and guides directly to your coding assistant. Useful for inspecting the zero-shot classification API without switching to a browser.

## What it does

This MCP server exposes documentation tools for classifier.dev, covering its zero-shot classification API, benchmarks, and guides. The underlying service handles text classification without signups or API keys, returning labels alongside calibrated probabilities. Through MCP, coding assistants can inspect endpoint contracts, batching rules for up to one thousand items, and CLI usage.

The documentation covers the Jev decision model, latency tests, and the `feedback.now` protocol for structured error reporting from agents. Because classifier.dev is hosted as a Cloudflare Worker, the docs also clarify deployment details and rate limits.

Running these tools requires outbound HTTP access to `https://classifier.dev/mcp/docs`, with no local dependencies or Node packages to build.

## Requirements
- Remote server: `https://classifier.dev/mcp/docs`

## Install

### Claude Code (native platform)

**Platform CLI: remote server**
```bash
claude mcp add --transport http docs https://classifier.dev/mcp/docs
```

### Codex

**Platform CLI: remote server**
```bash
codex mcp add classifierdev-docs --url https://classifier.dev/mcp/docs
```

### Cursor

**Config file**
File `.cursor/mcp.json`:
```json
{
    "mcpServers": {
        "classifierdev-docs": {
            "url": "https://classifier.dev/mcp/docs"
        }
    }
}
```

### GitHub Copilot

**Config file**
File `.vscode/mcp.json`:
```json
{
    "servers": {
        "classifierdev-docs": {
            "type": "http",
            "url": "https://classifier.dev/mcp/docs"
        }
    }
}
```

### Gemini CLI

**Platform CLI: remote server**
```bash
gemini mcp add -t http classifierdev-docs https://classifier.dev/mcp/docs
```

## When to use it
- search endpoint signatures for zero-shot text classification
- check batch processing limits for multi-item requests
- inspect schema specifications for the feedback.now protocol
- review latency measurements and benchmarks for the Jev model

## Example prompts
- "Search classifier.dev docs for the batch classification request format"
- "Show the feedback.now protocol specifications from the classifier.dev reference"
- "Check the classifier.dev benchmark numbers and latency for the Jev model"
