Aden Tools

Tool library for the Aden agent framework. Provides a collection of tools that AI agents can use to interact with external systems, process data, and perform actions via the Model Context Protocol (MCP).

Installation

uv pip install -e tools

For development:

uv pip install -e "tools[dev]"

Environment Setup

Some tools require API keys to function. Credentials are managed through the encrypted credential store at ~/.hive/credentials, which is configured automatically during initial setup:

./quickstart.sh

Variable	Required For	Get Key
ANTHROPIC_API_KEY	MCP server startup, LLM nodes	console.anthropic.com
BRAVE_SEARCH_API_KEY	web_search tool (Brave)	brave.com/search/api
GOOGLE_API_KEY	web_search tool (Google)	console.cloud.google.com
GOOGLE_CSE_ID	web_search tool (Google)	programmablesearchengine.google.com

Note: web_search supports multiple providers. Set either Brave OR Google credentials. Brave is preferred for backward compatibility.

Alternatively, export credentials as environment variables:

export ANTHROPIC_API_KEY=your-key-here
export BRAVE_SEARCH_API_KEY=your-key-here

See the credentials module for details on how credentials are resolved.

Quick Start

As an MCP Server

from fastmcp import FastMCP
from aden_tools.tools import register_all_tools

mcp = FastMCP("tools")
register_all_tools(mcp)
mcp.run()

Or run directly:

python mcp_server.py

Creating Custom Tools

Tools use FastMCP's native decorator pattern:

from fastmcp import FastMCP


def register_tools(mcp: FastMCP) -> None:
    @mcp.tool()
    def my_tool(query: str, limit: int = 10) -> dict:
        """
        Search for items matching the query.

        Args:
            query: The search query
            limit: Max results to return

        Returns:
            Dict with results or error
        """
        try:
            results = do_search(query, limit)
            return {"results": results, "total": len(results)}
        except Exception as e:
            return {"error": str(e)}
