About xbbg MCP

xbbg MCP is an MCP server published by the GitHub account underloam. Local Bloomberg tools for xbbg users.

It runs on your own machine: your AI client starts it from the MCP bundle package https://github.com/underloam/xbbg/releases/download/v1.6.0/xbbg-mcp-v1.6.0.mcpb at version 1.6.0.

It asks for no keys or passwords.

Version 1.6.0 was published on 23 October 2026, and the source code is public, so you can read it before installing.

Written from the registry entry. 8 automated checks on the registry entry and the package code: 6 pass, 0 warn, 0 fail, 2 info. How we check.
