Dynamic Workflow Tools

The server supports dynamic workflow tools that automatically discover and register tools based on workflows provided by a workflows-list-tool. This feature enables the server to expose workflow-based functionality as standard MCP tools without requiring code changes.

Enabling Workflow Tools

To enable dynamic workflow tools, set the following environment variable:

WORKFLOWS_ENABLED=true

When enabled, the server will:

  1. Query the workflows-list-tool to discover available workflows
  2. Automatically register MCP tools for each discovered workflow
  3. Handle workflow execution through standard MCP tool calls
  4. Provide status checking capabilities for running workflows

Workflow Tool Discovery

The server discovers workflows by calling a workflows-list-tool that should return an array of workflow definitions. Each workflow must conform to this schema:

{
  "id": "workflow-123",
  "name": "Data Analysis Workflow",
  "description": "Analyzes data and generates reports",
  "category": "analytics",
  "version": "1.0.0",
  "inputSchema": {
    "type": "object",
    "properties": {
      "dataset": {
        "type": "string",
        "description": "Path to the dataset file"
      },
      "format": {
        "type": "string",
        "enum": ["csv", "json", "xlsx"],
        "description": "Data format"
      }
    },
    "required": ["dataset"]
  },
  "executionType": "async",
  "metadata": {
    "estimatedDuration": "5-10 minutes",
    "resourceRequirements": "medium"
  }
}

Using Workflow Tools

Once discovered, workflow tools appear in the standard MCP tools list and can be called like any other tool:

{
  "name": "workflow-data-analysis-workflow",
  "arguments": {
    "dataset": "/path/to/data.csv",
    "format": "csv"
  }
}

Workflow Execution Flow

  1. Tool Call: MCP client calls a workflow tool with parameters
  2. Execution Start: Server makes POST call to workflow execution endpoint
  3. Status Polling: Server polls workflow status with minimum 1000ms intervals
  4. Result Return: Server returns workflow results in standard MCP format

Example execution response:

{
  "success": true,
  "data": {
    "workflowId": "workflow-123",
    "executionId": "exec-456",
    "status": "COMPLETED",
    "results": {
      "summary": "Analysis completed successfully",
      "reportUrl": "https://example.com/report.pdf",
      "metrics": {
        "recordsProcessed": 10000,
        "executionTime": "4m 32s"
      }
    }
  }
}

Workflow Status Checking

The server provides a built-in workflow-status-check tool for monitoring workflow executions:

{
  "name": "workflow-status-check",
  "arguments": {
    "workflowId": "workflow-123",
    "executionId": "exec-456"
  }
}

Status response includes:

  • Current execution status (RUNNING, COMPLETED, FAILED, CANCELLED)
  • Start and end times
  • Progress information (if available)
  • Input parameters and output results
  • Error details (if failed)

Range: 0-10
Recommendation:

  • Development: 1 for faster failure feedback
  • Production: 3-5 for reliability
# No retries for testing
WORKFLOW_RETRY_ATTEMPTS=0

# More retries for production reliability
WORKFLOW_RETRY_ATTEMPTS=5

Configuration Best Practices

Development Environment

# Fast feedback, lower resource usage
WORKFLOWS_ENABLED=true
WORKFLOW_DISCOVERY_INTERVAL=60000
WORKFLOW_EXECUTION_TIMEOUT=120000
WORKFLOW_MAX_CONCURRENT_EXECUTIONS=3
WORKFLOW_STATUS_CHECK_INTERVAL=2000
WORKFLOW_RETRY_ATTEMPTS=1
WORKFLOW_FILTER_PATTERNS=dev-*,test-*
LOG_LEVEL=debug

Production Environment

# Stability and performance focused
WORKFLOWS_ENABLED=true
WORKFLOW_DISCOVERY_INTERVAL=600000
WORKFLOW_EXECUTION_TIMEOUT=600000
WORKFLOW_MAX_CONCURRENT_EXECUTIONS=15
WORKFLOW_STATUS_CHECK_INTERVAL=5000
WORKFLOW_RETRY_ATTEMPTS=3
WORKFLOW_FILTER_PATTERNS=prod-*
LOG_LEVEL=warn

Testing Environment

# Predictable behavior for tests
WORKFLOWS_ENABLED=false
WORKFLOW_DISCOVERY_INTERVAL=0
WORKFLOW_EXECUTION_TIMEOUT=30000
WORKFLOW_MAX_CONCURRENT_EXECUTIONS=1
WORKFLOW_STATUS_CHECK_INTERVAL=1000
WORKFLOW_RETRY_ATTEMPTS=0
LOG_LEVEL=error

Configuration Validation

The server validates all workflow configuration on startup and provides detailed error messages for invalid values:

# Example validation error
Configuration validation failed:
Invalid configuration values: workflowExecutionTimeout: Workflow execution timeout must be at least 1000ms (1 second)

Workflow configuration guidelines:
- Set WORKFLOW_DISCOVERY_INTERVAL to 0 to disable automatic refresh
- Use WORKFLOW_FILTER_PATTERNS to limit which workflows are exposed (e.g., "data-*,report-*")
- Minimum WORKFLOW_STATUS_CHECK_INTERVAL is 1000ms to avoid excessive API calls
- WORKFLOW_EXECUTION_TIMEOUT should be set based on your longest-running workflows

Performance Considerations

API Rate Limiting

  • Set WORKFLOW_DISCOVERY_INTERVAL to at least 60 seconds to avoid rate limits
  • Use WORKFLOW_STATUS_CHECK_INTERVAL of at least 2 seconds for status polling
  • Consider the total API load: discovery + (concurrent executions status checks)

Resource Management

  • Monitor memory usage with high WORKFLOW_MAX_CONCURRENT_EXECUTIONS
  • Long-running workflows may require increased WORKFLOW_EXECUTION_TIMEOUT
  • Use workflow filtering to reduce the number of registered tools

Monitoring Recommendations

# Enable detailed logging for monitoring
LOG_LEVEL=info

# Set reasonable limits
WORKFLOW_MAX_CONCURRENT_EXECUTIONS=10
WORKFLOW_EXECUTION_TIMEOUT=300000

# Monitor workflow performance
WORKFLOW_STATUS_CHECK_INTERVAL=5000

Troubleshooting

Common Issues

Server Won't Start

Problem: Server fails to start with configuration error.

Solution:

  1. Verify your .env file contains SIMPLIFIED_API_TOKEN
  2. Check that your API token is valid
  3. Ensure Node.js version is 18.0.0 or higher
# Check Node.js version
node --version

# Verify environment variables
echo $SIMPLIFIED_API_TOKEN

Authentication Errors

Problem: API calls fail with authentication errors.

Solution:

  1. Verify your API token is correct and not expired
  2. Check that the token has the necessary permissions
  3. Ensure the API base URL is correct

Tool Execution Failures

Problem: Tools return errors or unexpected results.

Solution:

  1. Check the tool parameters match the expected schema
  2. Verify the API endpoint exists and is accessible
  3. Check server logs for detailed error information
# Enable debug logging
LOG_LEVEL=debug simplified-mcp-server

Connection Issues

Problem: Cannot connect to Simplified API.

Solution:

  1. Check your internet connection
  2. Verify the API base URL is accessible
  3. Check if there are any firewall restrictions
  4. Use the health check tool to diagnose connectivity

Workflow Tool Issues

Problem: Workflow tools are not appearing in the tools list.

Solution:

  1. Verify WORKFLOWS_ENABLED=true is set in your environment
  2. Check that the workflows-list-tool is available and responding
  3. Verify workflow definitions match the expected schema
  4. Check server logs for workflow discovery errors
# Enable debug logging to see workflow discovery details
LOG_LEVEL=debug simplified-mcp-server

Problem: Workflow execution times out or fails.

Solution:

  1. Increase WORKFLOW_EXECUTION_TIMEOUT for longer-running workflows
  2. Check workflow status using the workflow-status-check tool
  3. Verify workflow parameters match the expected schema
  4. Check if the workflow execution system is available
# Increase timeout to 10 minutes for long workflows
WORKFLOW_EXECUTION_TIMEOUT=600000

Problem: Too many concurrent workflow executions causing errors.

Solution:

  1. Reduce WORKFLOW_MAX_CONCURRENT_EXECUTIONS to limit resource usage
  2. Implement workflow queuing in your application
  3. Monitor system resources during peak usage
# Limit to 5 concurrent executions
WORKFLOW_MAX_CONCURRENT_EXECUTIONS=5

Problem: Workflow discovery is too frequent and causing API rate limits.

Solution:

  1. Increase WORKFLOW_DISCOVERY_INTERVAL to reduce API calls
  2. Set to 0 to disable automatic discovery and use manual refresh
  3. Implement workflow caching in your application
# Refresh workflows every 30 minutes instead of every 5 minutes
WORKFLOW_DISCOVERY_INTERVAL=1800000

# Or disable automatic discovery
WORKFLOW_DISCOVERY_INTERVAL=0

Problem: Only some workflows are being discovered.

Solution:

  1. Check WORKFLOW_FILTER_PATTERNS configuration
  2. Verify workflow names match your filter patterns
  3. Remove filters to see all available workflows
# Remove all filters to see all workflows
WORKFLOW_FILTER_PATTERNS=

# Or adjust patterns to include more workflows
WORKFLOW_FILTER_PATTERNS=*

Debug Mode

Enable debug logging for detailed troubleshooting:

LOG_LEVEL=debug simplified-mcp-server

Health Check

Use the built-in health check tool to verify server status:

{
  "name": "simplified-health-check",
  "arguments": {
    "includeDetails": true
  }
}

Workflow Troubleshooting Guide

Workflow Discovery Issues

Symptom: No workflow tools appear in tools list despite WORKFLOWS_ENABLED=true

Diagnostic Steps:

  1. Enable debug logging: LOG_LEVEL=debug
  2. Check server startup logs for workflow discovery messages
  3. Verify workflows-list-tool is available and responding

Common Causes & Solutions:

# Cause: workflows-list-tool not found
# Solution: Ensure the tool is properly registered and available
LOG_LEVEL=debug simplified-mcp-server
# Look for: "Workflow discovery failed: workflows-list-tool not found"

# Cause: Invalid workflow definitions
# Solution: Check workflow schema compliance
# Look for: "Skipping invalid workflow: missing required field 'name'"

# Cause: All workflows filtered out
# Solution: Check filter patterns
WORKFLOW_FILTER_PATTERNS=  # Remove filters temporarily

Symptom: Workflows discovered but tools not registered

Diagnostic Steps:

  1. Check for tool name conflicts in logs
  2. Verify workflow names are valid MCP tool names
  3. Look for schema validation errors

Solutions:

# Enable detailed tool registration logging
LOG_LEVEL=debug

# Check for naming conflicts
# Look for: "Tool name conflict: workflow-data-processor already exists"

# Verify workflow names contain only valid characters
# Valid: data-processor, report_generator, analysis123
# Invalid: data processor, report-generator!, anlisis

Workflow Execution Issues

Symptom: Workflow execution times out

Diagnostic Steps:

  1. Check workflow execution logs
  2. Verify workflow is actually running
  3. Monitor workflow status manually

Solutions:

# Increase timeout for long-running workflows
WORKFLOW_EXECUTION_TIMEOUT=1800000  # 30 minutes

# Check workflow status manually
{
  "name": "workflow-status-check",
  "arguments"
