APIWeaver + Apify MCP Tester: Complete MCP Integration
APIWeaver is a MCP server that An MCP server that dynamically creates MCP servers from web API configurations. This allows you to easily integrate any REST API, GraphQL endpoint, or web service into an MCP-compatible tool that can be used by AI assistants like Claude..
When integrated with Apify MCP Tester, you can:
- Register and configure APIs at runtime without server restart
- Support for REST APIs, GraphQL endpoints, and web services
- Multiple authentication methods for different API requirements
This guide provides step-by-step instructions to set up APIWeaver in Apify MCP Tester, including configuration, examples, and troubleshooting.
What You'll Achieve
After completing this setup:
- APIWeaver will be fully integrated and operational
- You can use APIWeaver tools directly in Apify MCP Tester
- All APIWeaver capabilities will be available for your workflows
- Access to 6 different tools
Prerequisites
Before starting, ensure you have:
- Apify MCP Tester installed and configured
- Compatible operating system (Web Browser)
Installation
Step 1: Install APIWeaver
Configuration
Step 2: Configure Apify MCP Tester
- Open Apify MCP Tester settings
- Navigate to MCP server configuration
- Add APIWeaver server with appropriate settings
- Save and restart if needed
Examples
Once configured, you can use APIWeaver in Apify MCP Tester:
Register REST API with Authentication
Add a REST API with Bearer token authentication
Ask Apify MCP Tester: "Register the JSONPlaceholder API (https://jsonplaceholder.typicode.com) with GET and POST methods"
Expected Result: API registered successfully with auto-generated tools for posts, users, and comments endpoints
GraphQL Endpoint Integration
Connect to a GraphQL API for data querying
Ask Apify MCP Tester: "Register the GitHub GraphQL API with authentication and create tools for repository queries"
Expected Result: GraphQL endpoint configured with query tools for repositories, issues, and user data
API Testing and Validation
Test API connectivity before integration
Ask Apify MCP Tester: "Test connection to the Stripe API with my API key before registering it"
Expected Result: Connection test successful with API schema validation and endpoint verification
Multi-API Workflow
Integrate multiple APIs for complex workflows
Ask Apify MCP Tester: "Register both Twitter API and SendGrid API to create a workflow for social media monitoring and email alerts"
Expected Result: Both APIs registered with tools for tweet monitoring, email sending, and automated workflow execution
Testing Your Setup
- Launch Apify MCP Tester
- Verify APIWeaver is available in the tools list
- Test basic APIWeaver functionality
Troubleshooting
Common Issues
API Registration Failed
Symptoms: Registration errors, Invalid API configuration, Connection timeouts
Cause: Incorrect API URL, authentication issues, or network problems
Solution:
- Verify API endpoint URL is accessible
- Check authentication credentials are valid
- Test API manually with curl or Postman first
- Ensure network connectivity and firewall settings
Authentication Not Working
Symptoms: 401 Unauthorized, 403 Forbidden, Auth token invalid
Cause: Incorrect authentication method or invalid credentials
Solution:
- Verify authentication method matches API requirements
- Check API key/token is not expired
- Confirm header format and parameter names
- Test authentication with API documentation examples
Transport Mode Not Connecting
Symptoms: Connection refused, Transport errors, Client not recognizing server
Cause: Incorrect transport configuration or port conflicts
Solution:
- Use streamable-http for modern clients
- Check port is not in use: netstat -an | grep :8000
- Verify host/port settings match client configuration
- Try different transport modes (stdio/http/sse)
Python Dependencies Missing
Symptoms: Import errors, Module not found, Package installation failures
Cause: Missing Python packages or virtual environment issues
Solution:
- Install requirements: pip install -r requirements.txt
- Create virtual environment: python -m venv apiweaver-env
- Activate environment before installation
- Upgrade pip: python -m pip install --upgrade pip
API Schema Generation Failed
Symptoms: Tool generation errors, Schema parsing failures, Endpoint mapping issues
Cause: Unsupported API format or incomplete API documentation
Solution:
- Provide OpenAPI/Swagger specification if available
- Start with simple GET endpoints first
- Manually configure complex APIs step by step
- Check API documentation for required parameters
Connection Failed
Symptoms: Cannot connect to server, Timeout errors
Cause: Server configuration or network connectivity issues
Solution:
- Verify server URL is correct and accessible
- Check if server supports chosen transport method (SSE/HTTP)
- Ensure server is running and accepting connections
- Check firewall and network settings
Tools Not Discovered
Symptoms: Empty tools list, Server connected but no capabilities
Cause: Server not properly implementing MCP protocol
Solution:
- Verify server implements MCP protocol correctly
- Check server logs for tool registration issues
- Ensure server is properly configured and initialized
- Test with known working MCP server for comparison
Tool Execution Fails
Symptoms: Tools available but not responding, Error messages during execution
Cause: Server-side errors or parameter issues
Solution:
- Check tool parameter requirements and formats
- Review server logs for execution errors
- Verify required environment variables are set
- Test with simpler tool calls first
APIWeaver not appearing in Apify MCP Tester
Symptoms: Server not listed, Tools not available
Cause: Configuration or installation issue
Solution:
- Verify configuration syntax
- Check APIWeaver installation
- Restart Apify MCP Tester
- Check logs for error messages
