# UniFuncs MCP Server

MCP Server for the UniFuncs API - Enhanced with Deep Search and Deep Research capabilities

## Features

This MCP server provides access to the following UniFuncs APIs:

### 1. Web Search (`web-search`)
Real-time web search with comprehensive results
- Search across the internet with keywords
- Filter by freshness (Day/Week/Month/Year)

### 2. Web Reader (`web-reader`)
Extract detailed content from web pages
- Clean content extraction
- Optional image inclusion
- Link summary support
- Markdown output

### 3. Deep Search - Sync (`deep-search-sync`)
Real-time deep search with immediate results
- Model: S3 / S3 Pro
- Streaming support
- Instant response

### 4. Deep Search - Async (`deep-search-create-task` + `deep-search-query-task`)
Asynchronous deep search for complex queries
- Create task and get task_id immediately
- Poll for task status and results
- Background processing for large queries

### 5. Deep Research (`deep-research-create-task` + `deep-research-query-task`)
Comprehensive deep research capabilities
- Models: U3, U3 Pro
- Customizable research parameters:
  - Introduction: Set researcher persona
  - Reference style: link/number/footnote
  - Max depth: Up to 50 iterations (25 recommended)

## Setup

### API Key

Get a UniFuncs API Key:
https://unifuncs.com/account

### NPX (STDIO)

```json
{
    "mcpServers": {
        "unifuncs": {
            "command": "npx",
            "args": [
                "-y",
                "@unifuncs/ufn-mcp-server"
            ],
            "env": {
                "UNIFUNCS_API_KEY": "sk-**********"
            }
        }
    }
}
```

Note: the `npx` experience reflects the latest package published to npm, not necessarily the current `main` branch. If the published npm version is behind `main`, use the source build instructions below to reproduce the latest merged toolset.

### Source Build (Local)

```bash
git clone https://github.com/UniFuncs/ufn-mcp-server.git
cd ufn-mcp-server
yarn install
npm run build
UNIFUNCS_API_KEY=sk-********** node build/index.js
```

Example Codex MCP config:

```toml
[mcp_servers.unifuncs-local]
command = "node"
args = ["/absolute/path/to/ufn-mcp-server/build/index.js"]

[mcp_servers.unifuncs-local.env]
UNIFUNCS_API_KEY = "sk-**********"
```

### SSE Server

For SSE transport, set the environment variable:

```bash
export UNIFUNCS_SSE_SERVER=true
export UNIFUNCS_SSE_SERVER_PORT=5656  # Optional, default is 5656
```

Or use the `--sse` flag:

```bash
npx @unifuncs/ufn-mcp-server --sse
```
