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

Prerequisites

Before starting, ensure you have:

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

Installation

Step 1: Install APIWeaver

Configuration

Step 2: Configure MindPal

1. Open MindPal 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 MindPal:

Register REST API with Authentication

Add a REST API with Bearer token authentication

Ask MindPal: "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 MindPal: "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 MindPal: "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 MindPal: "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 MindPal
2. Ask MindPal 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 Connection Failed

Symptoms: Connection test fails, Server unreachable error, Timeout during setup

Cause: Invalid server URL or server not accessible from cloud

Solution:

• Verify MCP server URL is correct and publicly accessible
• Check server is running and responding to requests
• Ensure server supports Streamable HTTP or SSE transport (STDIO not supported)
• Test server URL in browser or with curl to confirm accessibility
• Review server logs for connection errors

MCP Tools Not Available to Agent

Symptoms: Agent cannot access MCP tools, Tool calls fail, Tools not appearing in capabilities

Cause: MCP server not properly configured or tools not discovered

Solution:

• Verify MCP server connection shows "Connected" status
• Check that MCP server provides Tools (not just Resources or Prompts)
• Refresh agent settings to rediscover tools
• Test MCP server independently to ensure it is functioning
• Review MCP server documentation for proper tool implementation

Agent Not Understanding MCP Tool Usage

Symptoms: Agent does not use MCP tools when appropriate, Tool selection errors, Incorrect tool parameters

Cause: Ambiguous instructions or insufficient agent training

Solution:

• Provide more explicit instructions about when to use MCP tools
• Train agent with examples of correct MCP tool usage
• Add context about available MCP capabilities to agent knowledge
• Use specific tool names in prompts if agent is not selecting correctly

Workflow Automation Not Triggering

Symptoms: Multi-agent workflows not executing, Checkpoints not firing, Agent handoffs failing

Cause: Workflow configuration errors or trigger conditions not met

Solution:

• Verify workflow trigger conditions are properly set
• Check that all agents in workflow are active and configured
• Review workflow logs for execution errors
• Test each workflow step individually before combining
• Ensure MCP tools are accessible to all agents in workflow

High Usage or Rate Limiting

Symptoms: Plan limits exceeded warning, MCP calls being throttled, Tasks failing due to quota

Cause: Excessive automation or inefficient workflows

Solution:

• Review plan limits and current usage in account dashboard
• Optimize workflows to reduce unnecessary MCP calls
• Implement caching for frequently accessed data
• Add delays between automated tasks if hitting rate limits
• Upgrade plan if automation needs exceed current tier

APIWeaver not appearing in MindPal

Symptoms: Server not listed, Tools not available

Cause: Configuration or installation issue

Solution:

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