Description

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

  • server name
  • server version
  • server title

Additionally, adds similar tags to client tool spans:

  • For both client and server tool calls, mark which kind of tool call they are on a tag (as besides the name, which could vary for manual instrumentation, it is not apparent as they are just normal tool calls otherwise)
  • adds the mcp server name of the session the client tool call was used for

Lastly, generally for the mcp integration, we now mark client tool calls as errors when the tool result returned from the mcp server was an error as well.
