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

Prerequisites

Before starting, ensure you have:

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

Installation

Step 1: Install APIWeaver

Configuration

Step 2: Configure MooPoint

1. Open MooPoint 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 MooPoint:

Register REST API with Authentication

Add a REST API with Bearer token authentication

Ask MooPoint: "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 MooPoint: "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 MooPoint: "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 MooPoint: "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. Launch MooPoint
2. Verify APIWeaver is available in the tools list
3. 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

MCP Server Connection Failed

Symptoms: Connection timeout, Server unreachable, Test connection fails

Cause: Invalid server URL or server not accessible

Solution:

• Verify MCP server URL is correct and publicly accessible
• Check server supports HTTP or SSE transport protocol
• Ensure server is running and responding to health checks
• Test server URL in browser or with curl
• Review server logs for connection errors

OAuth Authentication Failing

Symptoms: OAuth redirect errors, Token refresh failures, Permission denied

Cause: Invalid OAuth credentials or misconfigured redirect URLs

Solution:

• Verify OAuth client ID and secret are correct
• Check redirect URL in OAuth provider matches MooPoint configuration
• Ensure all required scopes are configured
• Complete OAuth authorization flow fully
• Check OAuth provider allows the application

Tool Calling Not Working

Symptoms: Tools not appearing, Tool execution fails, LLM cannot access tools

Cause: MCP server not providing tools correctly or model limitations

Solution:

• Verify MCP server exposes tools in correct format
• Check that selected LLM model supports function calling
• Review tool definitions for correct parameter schemas
• Test MCP server independently to ensure tools work
• Try different LLM model that supports tool calling

API Key Errors

Symptoms: Invalid API key, Authentication failed, Rate limit errors

Cause: Incorrect or expired API keys for LLM providers

Solution:

• Verify API keys are correctly entered in Settings
• Check API key has not expired or been revoked
• Ensure API key has sufficient permissions
• Verify you have not exceeded rate limits or quotas
• Regenerate API key if issues persist

Model Switching Issues

Symptoms: Model not loading, Conversation context lost, Inconsistent behavior

Cause: Model compatibility or configuration issues

Solution:

• Ensure API key for selected model is configured
• Start new conversation when switching models
• Verify model supports required features (tool calling, etc.)
• Check model availability and status
• Review model-specific limitations and requirements

APIWeaver not appearing in MooPoint

Symptoms: Server not listed, Tools not available

Cause: Configuration or installation issue

Solution:

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