Description

Enable all components to operate as MCP Servers:

• Seamless microservice-level conversion to MCP via @register_microservice.
• Support TOOL, PROMPT, and RESOURCE function types.
• Allow dynamic addition of TOOL, PROMPT, and RESOURCE handlers to an existing MCP server instance.
• Include a dummy MCP server for basic testing purposes.

For each microservice:

• Update the decorator @register_microservice.
• Update docker compose file and helm charts to detect the environment variable ENABLE_MCP.
• Add a targeted test case to validate component functionality via an MCP client.
