MCP Server with HTTP Transport Layer: 404 page not found on available endpoints

[confusionhill]

Hi, i'm very new in mcp server development. wanted to ask.

on this docs https://mcp-go.dev/transports/http#endpoints it says that

When you start a StreamableHTTP MCP server, it automatically creates these endpoints:
POST /mcp/initialize     - Initialize MCP session
POST /mcp/tools/list     - List available tools
POST /mcp/tools/call     - Call a tool
POST /mcp/resources/list - List available resources
POST /mcp/resources/read - Read a resource
POST /mcp/prompts/list   - List available prompts
POST /mcp/prompts/get    - Get a prompt
GET  /mcp/health         - Health check
GET  /mcp/capabilities   - Server capabilities

so i tried to run it via curl

curl 127.0.0.1:8080/mcp/capabilities 
404 page not found

any particular reason why?
