How to Create a Downstream Connector for Your MCP Server
This guide walks you through creating a downstream connector in Findexar for your MCP server.
Prerequisites
- A Findexar organization (see Setup Your Org)
- An MCP server (Zapier, Make, n8n, OpenAI App SDK, or custom)
- MCP server endpoint URL and authentication credentials
Understanding Downstream Connectors
Downstream connectors are your backend MCP servers that do the actual work. They can be:
- Zapier MCP Server - Connect to Zapier automations
- Make MCP Server - Connect to Make.com workflows
- n8n MCP Server - Connect to n8n automations
- OpenAI App SDK MCP - Custom MCP servers built with OpenAI's SDK
- Custom MCP Servers - Any MCP-compatible service
For more details, see Understanding Connectors.
Step 1: Access Connector Settings
- Log in to your Findexar organization
- Navigate to your Project and Deployment
- Click on Connectors or Downstream Connectors
- Click Create Connector or Add Downstream Connector
Step 2: Select Connector Type
Choose the type of downstream connector you want to create:
Zapier MCP Server
- Select Zapier as the connector type
- Enter your Zapier MCP Server URL
- Provide API Key or authentication credentials
- Configure connection settings
Make MCP Server
- Select Make as the connector type
- Enter your Make MCP Server URL
- Provide API Key or authentication credentials
- Configure connection settings
n8n MCP Server
- Select n8n as the connector type
- Enter your n8n MCP Server URL
- Provide API Key or authentication credentials
- Configure connection settings
OpenAI App SDK MCP
- Select OpenAI App SDK as the connector type
- Enter your MCP Server URL
- Provide API Key or authentication credentials
- Configure connection settings
Custom MCP Server
- Select Custom as the connector type
- Enter your MCP Server URL
- Provide API Key or authentication credentials
- Configure connection settings
- Test the connection to verify it works
Step 3: Configure Connection
Configure the connection settings:
- Connector Name - Give your connector a descriptive name
- Server URL - The URL of your MCP server
- Authentication - API key, OAuth, or other authentication method
- Connection Timeout - Set timeout for connection attempts
- Retry Settings - Configure retry logic for failed requests
Step 4: Test Connection
Test the connection to ensure it works:
- Click Test Connection
- Verify that the connection is successful
- Check that tools are discovered correctly
- Review any warnings or errors
Step 5: Save and Verify
- Save the connector configuration
- Verify that the connector appears in your connector list
- Check that tools are available and accessible
- Test a tool call to ensure it works correctly
Step 6: Configure Tools (Optional)
After creating the connector, you can configure individual tools:
- Navigate to the connector details
- Review the Available Tools list
- Configure tool settings if needed
- Set default parameters or constraints
Troubleshooting
Connection Issues
- Connection timeout - Check your MCP server URL and network connectivity
- Authentication failed - Verify your API key or credentials
- Tools not discovered - Ensure your MCP server is properly configured
Tool Issues
- Tools not available - Check that your MCP server exposes tools correctly
- Tool calls failing - Verify tool parameters and server response format
- Performance issues - Check server response times and optimize if needed
Next Steps
Now that your downstream connector is created:
- Create an Upstream MCP Connector - Create the MCP endpoint for ChatGPT
- Map Tools - Select which tools to expose in your upstream connector
- Set Credit Prices - Configure pricing for each tool
