Aucterra MCP Server

This repository configures an MCP-compatible server for Aucterra's Document Understanding APIs using the aucterra-mcp package.

It enables LLM agents to interact with Aucterra's document classification, extraction, etc. services using Google's Agent Development Kit (ADK).

🔧 Configuration

Include this block in your mcpServers configuration (e.g., config.json or mcp.yaml):

{
  "mcpServers": {
    "aucterra": {
      "command": "pipx",
      "args": [
        "run",
        "--spec",
        "git+https://github.com/japisuru/aucterra-mcp",
        "aucterra-mcp"
      ],
      "env": {
        "AUCTERRA_API_KEY": "your_api_key_here"
      }
    }
  }
}

⚙️ Tool Behavior

This MCP tool provides structured access to Aucterra's:

• 📁 Document Classification

• 🗂️ Key-Value Field Extraction (Simple + List fields)

The tool accepts pdf or image files and returns structured JSON output.

✅ Agent Integration (Google ADK)

To use this tool within your LlmAgent, configure it as follows:

from google.adk.tools.mcp_tool.mcp_toolset import MCPToolset, StdioServerParameters

aucterra_tool = MCPToolset(
    connection_params=StdioServerParameters(
        command="pipx",
        args=[
            "run",
            "--spec",
            "git+https://github.com/japisuru/aucterra-mcp",
            "aucterra-mcp"
        ],
        env={"AUCTERRA_API_KEY": "your_api_key_here"}
    )
)

Add this tool to your agent via tools=[aucterra_tool].

📚 Example Use Cases

User: Classify this document (/path/to/the/document/doc.pdf) into invoice or identity document.
User: Extract the following fields: NIC, Full Name, Date of Birth from this document (/path/to/the/document/doc.pdf) 
User: Extract Tax ID as 'Tax Identification Number' from this document (/path/to/the/document/doc.pdf).

The agent will use the Aucterra MCP server to extract fields, filling in missing values (e.g., using the same value for field_key and field_name if only one is provided).

📦 Dependencies

Ensure pipx is installed and available on your system.
Install it via:

python3 -m pip install --user pipx
python3 -m pipx ensurepath

🛠️ Issues
