MySQL MCP Release v2.0.9

What's New

🔒 Security

• PII Redaction — New ENABLE_PII_REDACTION flag scrubs emails, phone numbers, SSNs, credit cards, and IPv4 addresses from query results before they reach the LLM. Includes column-name heuristics, regex value scanning, Luhn-verified card masking, SELECT * guard, column-reference guard, and introspection filtering. Opt-in, disabled by default. (by @Morkos)

🐛 Bug Fixes

• BIGINT precision loss — New MYSQL_BIG_NUMBER_STRINGS=true env var returns BIGINT/DECIMAL values as strings, preserving full precision for snowflake IDs and values exceeding Number.MAX_SAFE_INTEGER. (by @duyiliu)
• Remote MCP parallel hang — Fixed a hang in IS_REMOTE_MCP=true mode where two concurrent POST /mcp requests caused one to never return. Now creates a per-request Server instance instead of sharing the module-level one. (by @tomer-azar)

• Added repository, bugs, and homepage fields to package.json so npm users can navigate back to the source. (by @SyntaxHQDEV)

🔌 Integrations

• Added Codex CLI plugin manifest for listing in the Codex plugin ecosystem. (by @internet-dot)
