APIWeaver + Lutra AI: 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 Lutra AI, 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 Lutra AI, 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 Lutra AI
• All APIWeaver capabilities will be available for your workflows
• Access to 6 different tools

Prerequisites

Before starting, ensure you have:

• Lutra AI installed and configured
• Compatible operating system (Web Platform, Mobile Web)

Installation

Step 1: Install APIWeaver

Configuration

Step 2: Configure Lutra AI

1. Open Lutra AI settings
2. Navigate to MCP server configuration
3. Add APIWeaver server with appropriate settings
4. Save and restart if needed

Examples

Once configured, you can use APIWeaver in Lutra AI:

Register REST API with Authentication

Add a REST API with Bearer token authentication

Ask Lutra AI: "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 Lutra AI: "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 Lutra AI: "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 Lutra AI: "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

1. Start a new conversation in Lutra AI
2. Ask Lutra AI to list available tools
3. Try using 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

MCP Server Not Connecting

Symptoms: Server not appearing in connections, Connection timeout, Unable to reach server

Cause: Invalid server URL or server not accessible

Solution:

• Verify MCP server URL is correct and accessible
• Check server is running and responding to requests
• Ensure server supports HTTP/SSE transport (Lutra requirement)
• Test server URL in browser or with curl to confirm accessibility
• Contact Lutra support if server should be compatible

Authentication Failures

Symptoms: OAuth errors, Permission denied, Unauthorized access

Cause: OAuth not configured or credentials expired

Solution:

• Complete OAuth authorization flow for connected apps
• Refresh expired credentials through connections panel
• Verify required permissions are granted for each app
• Disconnect and reconnect app if authentication persists

Lutra Not Understanding Tasks

Symptoms: Incorrect task execution, Lutra asks for clarification repeatedly, Wrong app or tool used

Cause: Ambiguous instructions or insufficient context

Solution:

• Provide clear, specific instructions with context
• Specify which app or MCP server to use if ambiguous
• Break complex tasks into smaller, clearer steps
• Use examples or reference previous successful tasks

Playbooks Not Working

Symptoms: Playbook execution fails, Different results than expected, Missing steps

Cause: Changed app configurations or unavailable resources

Solution:

• Review playbook steps to ensure they are still valid
• Update playbook if app configurations have changed
• Verify all connected apps and MCP servers are accessible
• Test playbook step-by-step to identify failure point

Workflow Automation Limits

Symptoms: Task quota exceeded, Automation disabled, Rate limiting

Cause: Plan limits reached or service rate limits

Solution:

• Check Lutra plan limits and current usage
• Upgrade plan if automation needs exceed current tier
• Optimize workflows to reduce unnecessary API calls
• Implement delays between rapid successive automations

APIWeaver not appearing in Lutra AI

Symptoms: Server not listed, Tools not available

Cause: Configuration or installation issue

Solution:

• Verify configuration syntax
• Check APIWeaver installation
• Restart Lutra AI
• Check logs for error messages
