## Exception Classes
The BaseTool class defines several custom exception classes for better error handling:
- `BaseToolError`: Base exception class for all BaseTool related errors
- `ToolValidationError`: Raised when tool validation fails
- `ToolExecutionError`: Raised when tool execution fails
- `ToolNotFoundError`: Raised when a requested tool is not found
- `FunctionSchemaError`: Raised when function schema conversion fails
- `ToolDocumentationError`: Raised when tool documentation is missing or invalid
- `ToolTypeHintError`: Raised when tool type hints are missing or invalid
## Usage Tips
1. **Always provide documentation and type hints** for your functions when using BaseTool
2. **Use verbose=True** during development for detailed logging
3. **Set up function_map** for efficient tool execution by name
4. **Validate schemas** before using them with different AI providers
5. **Use parallel execution** for better performance when executing multiple functions
6. **Handle exceptions** appropriately using the custom exception classes

## Method 1: Callable Functions
Callable functions are the simplest way to add tools to your Swarms agents. They are regular Python functions with type hints and comprehensive docstrings.
### Step 1: Define Your Tool Functions
Create functions with the following requirements:
- **Type hints** for all parameters and return values
- **Comprehensive docstrings** with Args, Returns, Raises, and Examples sections
- **Error handling** for robust operation
#### Example: Cryptocurrency Price Tools
```python
import json
import requests
from swarms import Agent
def get_coin_price(coin_id: str, vs_currency: str = "usd") -> str:
"""
Get the current price of a specific cryptocurrency.
Args:
coin_id (str): The CoinGecko ID of the cryptocurrency
Examples: 'bitcoin', 'ethereum', 'cardano'
vs_currency (str, optional): The target currency for price conversion.
Supported: 'usd', 'eur', 'gbp', 'jpy', etc.
Defaults to "usd".
Returns:
str: JSON formatted string containing the coin's current price and market data
including market cap, 24h volume, and price changes
Raises:
requests.RequestException: If the API request fails due to network issues
ValueError: If coin_id is empty or invalid
TimeoutError: If the request takes longer than 10 seconds
Example:
>>> result = get_coin_price("bitcoin", "usd")
>>> print(result)
{"bitcoin": {"usd": 45000, "usd_market_cap": 850000000000, ...}}

### Step 2: Configure Your Agent
Create an agent with the following key parameters:
```python
# Initialize the agent with cryptocurrency tools
agent = Agent(
agent_name="Financial-Analysis-Agent", # Unique identifier for your agent
agent_description="Personal finance advisor agent with cryptocurrency market analysis capabilities",
system_prompt="""You are a personal finance advisor agent with access to real-time
cryptocurrency data from CoinGecko. You can help users analyze market trends, check
coin prices, find trending cryptocurrencies, and search for specific coins. Always
provide accurate, up-to-date information and explain market data in an easy-to-understand way.""",
max_loops=1, # Number of reasoning loops
max_tokens=4096, # Maximum response length
model_name="anthropic/claude-3-opus-20240229", # LLM model to use
dynamic_temperature_enabled=True, # Enable adaptive creativity
output_type="all", # Return complete response
tools=[ # List of callable functions
get_coin_price,
get_top_cryptocurrencies,
search_cryptocurrencies,
],
)
```
### Step 3: Use Your Agent
```python
# Example usage with different queries
response = agent.run("What are the top 5 cryptocurrencies by market cap?")
print(response)
# Query with specific parameters
response = agent.run("Get the current price of Bitcoin and Ethereum in EUR")
print(response)
# Search functionality
response = agent.run("Search for cryptocurrencies related to 'cardano'")
print(response)
```

## Method 2: MCP (Model Context Protocol) Servers
MCP servers provide a standardized way to create distributed tool functionality. They're ideal for:
- **Reusable tools** across multiple agents
- **Complex tool logic** that needs isolation
- **Third-party tool integration**
- **Scalable architectures**
### Step 1: Create Your MCP Server
```python
from mcp.server.fastmcp import FastMCP
import requests
# Initialize the MCP server with configuration
mcp = FastMCP("OKXCryptoPrice") # Server name for identification
mcp.settings.port = 8001 # Port for server communication
```
### Step 2: Define MCP Tools
Each MCP tool requires the `@mcp.tool` decorator with specific parameters:
```python
@mcp.tool(
name="get_okx_crypto_price", # Tool identifier (must be unique)
description="Get the current price and basic information for a given cryptocurrency from OKX exchange.",
)
def get_okx_crypto_price(symbol: str) -> str:
"""
Get the current price and basic information for a given cryptocurrency using OKX API.
Args:
symbol (str): The cryptocurrency trading pair
Format: 'BASE-QUOTE' (e.g., 'BTC-USDT', 'ETH-USDT')
If only base currency provided, '-USDT' will be appended
Case-insensitive input
Returns:
str: A formatted string containing:
- Current price in USDT
- 24-hour price change percentage
- Formatted for human readability
Raises:
requests.RequestException: If the OKX API request fails
ValueError: If symbol format is invalid
ConnectionError: If unable to connect to OKX servers
Example:
>>> get_okx_crypto_price('BTC-USDT')
'Current price of BTC/USDT: $45,000.00\n24h Change: +2.34%'
>>> get_okx_crypto_price('eth') # Automatically converts to ETH-USDT
'Current price of ETH/USDT: $3,200.50\n24h Change: -1.23%'
"""
try:
# Input validation and formatting
if not symbol or not symbol.strip():
return "Error: Please provide a valid trading pair (e.g., 'BTC-USDT')"
# Normalize symbol format
symbol = symbol.upper().strip()
if not symbol.endswith("-USDT"):
symbol = f"{symbol}-USDT"
# OKX API endpoint for ticker information
url = f"https://www.okx.com/api/v5/market/ticker?instId={symbol}"
# Make the API request with timeout
response = requests.get(url, timeout=10)
response.raise_for_status()
data = response.json()
# Check API response status
if data.get("code") != "0":
return f"Error: {data.get('msg', 'Unknown error from OKX API')}"
# Extract ticker data
ticker_data = data.get("data", [{}])[0]
if not ticker_data:
return f"Error: Could not find data for {symbol}. Please verify the trading pair exists."
# Parse numerical data
price = float(ticker_data.get("last", 0))
change_percent = float(ticker_data.get("change24h", 0)) * 100 # Convert to percentage
# Format response
base_currency = symbol.split("-")[0]
change_symbol = "+" if change_percent >= 0 else ""
return (f"Current price of {base_currency}/USDT: ${price:,.2f}\n"
f"24h Change: {change_symbol}{change_percent:.2f}%")
except requests.exceptions.Timeout:
return "Error: Request timed out. OKX servers may be slow."
except requests.exceptions.RequestException as e:
return f"Error fetching OKX data: {str(e)}"
except (ValueError, KeyError) as e:
return f"Error parsing OKX response: {str(e)}"
except Exception as e:
return f"Unexpected error: {str(e)}"
@mcp.tool(
name="get_okx_crypto_volume", # Second tool with different functionality
description="Get the 24-hour trading volume for a given cryptocurrency from OKX exchange.",
)
def get_okx_crypto_volume(symbol: str) -> str:
"""
Get the 24-hour trading volume for a given cryptocurrency using OKX API.
Args:
symbol (str): The cryptocurrency trading pair
Format: 'BASE-QUOTE' (e.g., 'BTC-USDT', 'ETH-USDT')

Case-insensitive input
Returns:
str: A formatted string containing:
- 24-hour trading volume in the base currency
- Volume formatted with thousand separators
- Currency symbol for clarity
Raises:
requests.RequestException: If the OKX API request fails
ValueError: If symbol format is invalid
Example:
>>> get_okx_crypto_volume('BTC-USDT')
'24h Trading Volume for BTC/USDT: 12,345.67 BTC'
>>> get_okx_crypto_volume('ethereum') # Converts to ETH-USDT
'24h Trading Volume for ETH/USDT: 98,765.43 ETH'
"""
try:
# Input validation and formatting
if not symbol or not symbol.strip():
return "Error: Please provide a valid trading pair (e.g., 'BTC-USDT')"
# Normalize symbol format
symbol = symbol.upper().strip()
if not symbol.endswith("-USDT"):
symbol = f"{symbol}-USDT"
# OKX API endpoint
url = f"https://www.okx.com/api/v5/market/ticker?instId={symbol}"
# Make API request
response = requests.get(url, timeout=10)
response.raise_for_status()
data = response.json()
# Validate API response
if data.get("code") != "0":
return f"Error: {data.get('msg', 'Unknown error from OKX API')}"
ticker_data = data.get("data", [{}])[0]
if not ticker_data:
return f"Error: Could not find data for {symbol}. Please verify the trading pair."
# Extract volume data
volume_24h = float(ticker_data.get("vol24h", 0))
base_currency = symbol.split("-")[0]
return f"24h Trading Volume for {base_currency}/USDT: {volume_24h:,.2f} {base_currency}"
except requests.exceptions.RequestException as e:
return f"Error fetching OKX data: {str(e)}"
except Exception as e:
return f"Error: {str(e)}"
```
### Step 3: Start Your MCP Server
```python
if __name__ == "__main__":
# Run the MCP server with SSE (Server-Sent Events) transport
# Server will be available at http://localhost:8001/sse
mcp.run(transport="sse")
```
### Step 4: Connect Agent to MCP Server
```python
from swarms import Agent
# Method 2: Using direct URL (simpler for development)
mcp_url = "http://0.0.0.0:8001/sse"
# Initialize agent with MCP tools
agent = Agent(
agent_name="Financial-Analysis-Agent", # Agent identifier
agent_description="Personal finance advisor with OKX exchange data access",
system_prompt="""You are a financial analysis agent with access to real-time
cryptocurrency data from OKX exchange. You can check prices, analyze trading volumes,
and provide market insights. Always format numerical data clearly and explain
market movements in context.""",
max_loops=1, # Processing loops
mcp_url=mcp_url, # MCP server connection
output_type="all", # Complete response format
# Note: tools are automatically loaded from MCP server
)
```
### Step 5: Use Your MCP-Enabled Agent
```python
# The agent automatically discovers and uses tools from the MCP server
response = agent.run(
"Fetch the price for Bitcoin using the OKX exchange and also get its trading volume"
)
print(response)
# Multiple tool usage
response = agent.run(
"Compare the prices of BTC, ETH, and ADA on OKX, and show their trading volumes"
)
print(response)
```

# Getting Started with State-of-the-Art Vision Language Models (VLMs) Using the Swarms API
The intersection of vision and language tasks within the field of artificial intelligence has led to the emergence of highly sophisticated models known as Vision Language Models (VLMs). These models leverage the capabilities of both computer vision and natural language processing to provide a more nuanced understanding of multimodal inputs. In this blog post, we will guide you through the process of integrating state-of-the-art VLMs available through the Swarms API, focusing particularly on models like "internlm-xcomposer2-4khd", which represents a blend of high-performance language and visual understanding.
#### What Are Vision Language Models?
Vision Language Models are at the frontier of integrating visual data processing with text analysis. These models are trained on large datasets that include both images and their textual descriptions, learning to correlate visual elements with linguistic context. The result is a model that can not only recognize objects in an image but also generate descriptive, context-aware text, answer questions about the image, and even engage in a dialogue about its content.
#### Why Use Swarms API for VLMs?
Swarms API provides access to several cutting-edge VLMs including the "internlm-xcomposer2-4khd" model. This API is designed for developers looking to seamlessly integrate advanced multimodal capabilities into their applications without the need for extensive machine learning expertise or infrastructure. Swarms API is robust, scalable, and offers state-of-the-art models that are continuously updated to leverage the latest advancements in AI research.
#### Prerequisites
Before diving into the technical setup, ensure you have the following:
- An active account with Swarms API to obtain an API key.
- Python installed on your machine (Python 3.6 or later is recommended).
- An environment where you can install packages and run Python scripts (like Visual Studio Code, Jupyter Notebook, or simply your terminal).
#### Setting Up Your Environment
First, you'll need to install the `OpenAI` Python library if it's not already installed:
```bash
pip install openai
```
#### Integrating the Swarms API
Here’s a basic guide on how to set up the Swarms API in your Python environment:
1. **API Key Configuration**:
Start by setting up your API key and base URL. Replace `"your_swarms_key"` with the actual API key you obtained from Swarms.
```python
from openai import OpenAI
openai_api_key = "your_swarms_key"
openai_api_base = "https://api.swarms.world/v1"
```
2. **Initialize Client**:
Initialize your OpenAI client with the provided API key and base URL.
```python
client = OpenAI(
api_key=openai_api_key,
base_url=openai_api_base,
)
```
3. **Creating a Chat Completion**:
To use the VLM, you’ll send a request to the API with a multimodal input consisting of both an image and a text query. The following example shows how to structure this request:
```python
chat_response = client.chat.completions.create(
model="internlm-xcomposer2-4khd",
messages=[
{
"role": "user",
"content": [
{
"type": "image_url",
"image_url": {
"url": "https://upload.wikimedia.org/wikipedia/commons/thumb/d/dd/Gfp-wisconsin-madison-the-nature-boardwalk.jpg/2560px-Gfp-wisconsin-madison-the-nature-boardwalk.jpg",
},
},
{"type": "text", "text": "What's in this image?"},
]
}
],
)
print("Chat response:", chat_response)
```
This code sends a multimodal query to the model, which includes an image URL followed by a text question regarding the image.
#### Understanding the Response
The response from the API will include details generated by the model about the image based on the textual query. This could range from simple descriptions to complex narratives, depending on the model’s capabilities and the nature of the question.
#### Best Practices
- **Data Privacy**: Always ensure that the images and data you use comply with privacy laws and regulations.
- **Error Handling**: Implement robust error handling to manage potential issues during API calls.
- **Model Updates**: Keep track of updates to the Swarms API and model improvements to leverage new features and improved accuracies.
#### Conclusion
Integrating VLMs via the Swarms API opens up a plethora of opportunities for developers to create rich, interactive, and intelligent applications that understand and interpret the world not just through text but through visuals as well. Whether you’re building an educational tool, a content management system, or an interactive chatbot, these models can significantly enhance the way users interact with your application.
As you embark on your journey to integrate these powerful models into your projects, remember that the key to successful implementation lies in understanding the capabilities and limitations of the technology, continually testing with diverse data, and iterating based on user feedback and technological advances.
Happy coding, and here’s to building more intelligent, multimodal applications!

- **Total Tests**: {total_tests}
- **✅ Passed**: {passed_tests}
- **❌ Failed**: {failed_tests}
- **Success Rate**: {success_rate:.1f}%
## 🔧 Fixes Applied
This version addresses the following issues from the previous test run:
1. **Documentation Enhancement**: Added proper docstrings with Args and Returns sections
2. **Dependency Handling**: Graceful handling of missing `numpydoc` dependency
3. **Return Format Adaptation**: Tests now handle both simple values and complex result objects
4. **Parameter Validation**: Fixed parameter passing issues in function execution tests
5. **Schema Generation**: Use actual function schemas instead of manual test dictionaries
6. **Error Handling**: Improved error handling for various edge cases
## 🎯 Test Objective
This comprehensive test suite validates the functionality of all methods in the BaseTool class with basic use cases. The tests focus on:
- Method functionality verification
- Basic input/output validation
- Integration between different methods
- Schema generation and conversion
- Tool execution capabilities

This prompt is structured to elicit rigorous architectural decisions, precise language,

"""
return f"""
You are a deeply capable, autonomous agent architect tasked with generating a production-ready agent configuration. Your objective is to fully instantiate the `AgentConfiguration` schema for a highly specialized, purpose-driven AI agent tailored to the task outlined below.
--- TASK CONTEXT ---
You are to design an intelligent, self-sufficient agent whose behavior, cognitive capabilities, safety parameters, and operational bounds are entirely derived from the following user-provided task description:
**Task:** "{task}"
--- ROLE AND OBJECTIVE ---
You are not just a responder — you are an autonomous **system designer**, **architect**, and **strategist** responsible for building intelligent agents that will be deployed in real-world applications. Your responsibility includes choosing the most optimal behaviors, cognitive limits, resource settings, and safety thresholds to match the task requirements with precision and foresight.
You must instantiate **all fields** of the `AgentConfiguration` schema, as defined below. These configurations will be used directly by AI systems without human review — therefore, accuracy, reliability, and safety are paramount.
--- DESIGN PRINCIPLES ---
Follow these core principles in your agent design:
1. **Fitness for Purpose**: Tailor all parameters to optimize performance for the provided task. Understand the underlying problem domain deeply before configuring.
2. **Explainability**: The `agent_description` and `system_prompt` should clearly articulate what the agent does, how it behaves, and its guiding heuristics or ethics.
3. **Safety and Control**: Err on the side of caution. Enable guardrails unless you have clear justification to disable them.
4. **Modularity**: Your design should allow for adaptation and scaling. Prefer clear constraints over rigidly hard-coded behaviors.
5. **Dynamic Reasoning**: Allow adaptive behaviors only when warranted by the task complexity.
6. **Balance Creativity and Determinism**: Tune `temperature` and `top_p` appropriately. Analytical tasks should be conservative; generative or design tasks may tolerate more creative freedom.
--- FIELD-BY-FIELD DESIGN GUIDE ---
• **agent_name (str)**
- Provide a short, expressive, and meaningful name.
- It should reflect domain expertise and purpose, e.g., `"ContractAnalyzerAI"`, `"BioNLPResearcher"`, `"CreativeUXWriter"`.
• **agent_description (str)**
- Write a long, technically rich description.
- Include the agent’s purpose, operational style, areas of knowledge, and example outputs or use cases.
- Clarify what *not* to expect as well.
• **system_prompt (str)**
- This is the most critical component.
- Write a 5–15 sentence instructional guide that defines the agent’s tone, behavioral principles, scope of authority, and personality.
- Include both positive (what to do) and negative (what to avoid) behavioral constraints.
- Use role alignment (“You are an expert...”) and inject grounding in real-world context or professional best practices.
• **max_loops (int)**
- Choose a number of reasoning iterations. Use higher values (6–10) for exploratory, multi-hop, or inferential tasks.
- Keep it at 1–2 for simple retrieval or summarization tasks.
• **dynamic_temperature_enabled (bool)**
- Enable this for agents that must shift modes between creative and factual sub-tasks.
- Disable for deterministic, verifiable reasoning chains (e.g., compliance auditing, code validation).
• **model_name (str)**
- Choose the most appropriate model family: `"gpt-4"`, `"gpt-4-turbo"`, `"gpt-3.5-turbo"`, etc.
- Use lightweight models only if latency, cost, or compute efficiency is a hard constraint.
• **safety_prompt_on (bool)**
- Always `True` unless the agent is for internal, sandboxed research.
- This ensures harmful, biased, or otherwise inappropriate outputs are blocked or filtered.
• **temperature (float)**
- For factual, analytical, or legal tasks: `0.2–0.5`
- For content generation or creative exploration: `0.6–0.9`
- Avoid values >1.0. They reduce coherence.
• **max_tokens (int)**
- Reflect the expected size of the output per call.
- Use 500–1500 for concise tools, 3000–5000 for exploratory or report-generating agents.
- Never exceed the model limit (e.g., 8192 for GPT-4 Turbo).
• **context_length (int)**
- Set based on how much previous conversation or document context the agent needs to retain.
- Typical range: 6000–16000 tokens. Use lower bounds to optimize performance if context retention isn't crucial.
--- EXAMPLES OF STRONG SYSTEM PROMPTS ---
Bad example:
> "You are a helpful assistant that provides answers about contracts."
✅ Good example:
> "You are a professional legal analyst specializing in international corporate law. Your role is to evaluate contracts for risks, ambiguous clauses, and compliance issues. You speak in precise legal terminology and justify every assessment using applicable legal frameworks. Avoid casual language. Always flag high-risk clauses and suggest improvements based on best practices."
--- FINAL OUTPUT FORMAT ---
Output **only** the JSON object corresponding to the `AgentConfiguration` schema:
