Could you build this?

Partial While an MCP server with SQLite FTS5 is simple to build, decrypting and reverse-engineering local proprietary database formats across various versions of WeChat and DingTalk requires reverse engineering expertise.

What it would actually take: A developer needs Python/Go or TypeScript to write an MCP server wrapping an SQLite FTS5 index. The core challenge is extracting keys from memory or client binaries and decrypting the proprietary, heavily obfuscated SQLite formats used by desktop WeChat (SQLCipher with custom parameters) and DingTalk. Maintaining compatibility across app version updates requires continuous reverse engineering and binary analysis.
