[Bug]: Resources and Prompts not displaying in Admin Dashboard while Tools are visible

[umashanker088]

🐞 Bug Summary

I'm unable to see the my Resources and Prompts in MCP admin Dashboard which is presented in our MCP -Server , but we are able to see my all tools in MCP gateway Dashboard so that what is wrong I have implemented ?

The Problem

The gateway initialization process in mcpgateway/services/gateway_service.py only fetches tools from connected MCP servers, but never fetches resources or prompts. This happens in the _initialize_gateway method.

Current Implementation (Lines 1290-1337 in gateway_service.py)

Both the SSE and StreamableHTTP connection methods follow the same pattern:

# Current implementation - ONLY fetches tools
async with sse_client(url=server_url, headers=decoded_auth) as streams:
    async with ClientSession(*streams) as session:
        # Initialize the session
        response = await session.initialize()
        capabilities = response.capabilities.model_dump(by_alias=True, exclude_none=True)
        
        # ONLY fetches tools - missing resources and prompts!
        response = await session.list_tools()
        tools = response.tools
        tools = [tool.model_dump(by_alias=True, exclude_none=True) for tool in tools]
        
        return capabilities, tools  # Returns only capabilities and tools

Database Structure is Correct

The database models in mcpgateway/db.py are properly configured:

• Gateway model has relationships for resources and prompts (lines 1118-1121)
• Resource model has gateway_id and gateway relationship (lines 605-606)
• Prompt model has gateway_id and gateway relationship (lines 809-810)

Admin UI is Correct

The admin interface in mcpgateway/admin.py and templates are properly set up to display resources and prompts:

• Admin routes correctly fetch from services (lines 973, 1082)
• Templates have proper tables for resources and prompts
• Services have list_resources() and list_prompts() methods

The Fix

The _initialize_gateway method needs to be updated to also fetch resources and prompts from the MCP server:

Required Changes in gateway_service.py:

1. Update the SSE connection method (around line 1296):

# After fetching tools
response = await session.list_tools()
tools = response.tools
tools = [tool.model_dump(by_alias=True, exclude_none=True) for tool in tools]
tools = [ToolCreate.model_validate(tool) for tool in tools]

# ADD: Fetch resources
resources = []
if capabilities.get('resources'):  # Check if server supports resources
    response = await session.list_resources()
    resources = response.resources
    resources = [resource.model_dump(by_alias=True, exclude_none=True) for resource in resources]

# ADD: Fetch prompts  
prompts = []
if capabilities.get('prompts'):  # Check if server supports prompts
    response = await session.list_prompts()
    prompts = response.prompts
    prompts = [prompt.model_dump(by_alias=True, exclude_none=True) for prompt in prompts]

return capabilities, tools, resources, prompts  # Return all items

2. Update the StreamableHTTP connection method (similar changes around line 1330)

3. Update the method signature to return resources and prompts:

async def _initialize_gateway(self, url: str, authentication: str, transport: str = "SSE") -> Tuple[Dict, List[ToolCreate], List[ResourceCreate], List[PromptCreate]]:

4. Update the register_gateway method to handle resources and prompts:

capabilities, tools, resources, prompts = await self._initialize_gateway(normalized_url, auth_value, gateway.transport)

# Create DbResource and DbPrompt objects similar to DbTool
resources = [
    DbResource(
        uri=resource.uri,
        name=resource.name,
        description=resource.description,
        mime_type=resource.mime_type,
        gateway_id=db_gateway.id,
        # ... other fields
    )
    for resource in resources
]

prompts = [
    DbPrompt(
        name=prompt.name,
        description=prompt.description,
        arguments=prompt.arguments,
        gateway_id=db_gateway.id,
        # ... other fields
    )
    for prompt in prompts
]

# Add to the gateway
db_gateway = DbGateway(
    name=gateway.name,
    # ... other fields
    tools=tools,
    resources=resources,  # ADD this
    prompts=prompts,      # ADD this
)

5. Update the update_gateway and toggle_gateway_status methods similarly to sync resources and prompts when gateways are updated or reactivated.

Impact

This fix will:

1. Properly fetch resources and prompts from MCP servers during gateway registration
2. Store them in the database with proper gateway associations
3. Make them available in the Admin Dashboard alongside tools
4. Maintain consistency across all MCP protocol features

Testing Recommendations

After implementing the fix:

1. Test with an MCP server that exposes resources and prompts (like the one in the issue report)
2. Verify resources and prompts appear in the Admin Dashboard
3. Test gateway updates to ensure resources/prompts are re-synced
4. Test with servers that don't support resources/prompts to ensure backward compatibility

Summary

The issue is that the gateway service's initialization process is incomplete - it only fetches tools from MCP servers but ignores resources and prompts, even though the database and UI are ready to handle them. The fix requires updating the _initialize_gateway method to fetch all three types of items from the MCP server.
