Connects LLMs and AI agents directly to GitHub repositories, enabling repository inspection, file and tree exploration, code search, commit history, issues, pull requests, and releases for both public and private repos.

Enables an agent to run whole browser tasks on live web pages from a plain-language goal — opening tabs, clicking, typing, scrolling, and returning the relevant page sections as markdown — with every step reported alongside its confidence. Tabs can be reused and closed across calls, so multi-step flows continue on the page the previous task ended on.

This read-only MCP Server allows you to connect to GitHub data from Claude Desktop through CData JDBC Drivers. For full CRUD support, check out the first managed MCP platform: CData Connect AI (https://www.cdata.com/ai/).
