chore(mcp): add server info metadata on client session "root" spans #14828

sabrenner · 2025-10-09T13:18:12Z

Description

Adds server info metadata to llm observability mcp client session "root" spans. This information includes

server name
server version
server title
number of available tools

Not a customer-facing change as this will help power UI features and the data is not directly visible.

MLOB-4147

Testing

Add unit tests, and additionally, verified that the data shows up on a dummy application in the response from getting the llm observability traces:

for this simple FastMCP server

from mcp.server.fastmcp import FastMCP

# Create an MCP server
mcp = FastMCP(name="Demo")


# Add an addition tool
@mcp.tool()
def add(a: int, b: int) -> int:
    """Add two numbers"""
    return a + b


if __name__ == "__main__":
    mcp.run(transport="stdio")

Risks

None
