MySQL Legacy MCP

MCP server for legacy MySQL 5.0–5.6 databases through stdio. The package is on npm as mysql-legacy-mcp and in the official MCP Registry as io.github.Rufflet/mysql-legacy-mcp.

It uses MySQL 5.1-compatible SQL and SHOW metadata queries. Live MCP tests cover MySQL 5.0.51a, 5.1.73, 5.5.62, and 5.6.51. It is deliberately small: read-only by default, with INSERT/UPDATE/DELETE/DDL as opt-in tools disabled unless explicitly enabled; no TLS configuration, and no custom authentication or charset options.

Is this for you?

You need an AI agent to inspect a MySQL 5.0, 5.1, 5.5, or 5.6 database.
Your current MySQL MCP server assumes MySQL 5.7+, JSON functions, or newer information_schema fields.
You need schema inspection and SELECT queries, with write operations off by default and opt-in per statement type.

If you are seeing ER_NOT_SUPPORTED_AUTH_MODE, HANDSHAKE_INSECURE_AUTH, Old password authentication is not supported, legacy TLS errors, or garbled cp1251 / latin1 text, read Troubleshooting first. Those symptoms are not all solved by this package.

Requirements

Node.js 18.14.1 or later
npm
A dedicated MySQL account with only the required read and metadata privileges

Where it is listed

Installation is always local stdio via npm (npx -y mysql-legacy-mcp). Directory pages do not make that faster; they are discovery indexes. The official MCP Registry is the machine-readable source (io.github.Rufflet/mysql-legacy-mcp) that aggregators ingest, including env-var metadata from server.json. Clients that speak that registry can pre-fill configuration from it.

Maintainer submission status for other directories is in docs/RELEASE_CHECKLIST.md.

Quick install

Claude Code

claude mcp add --transport stdio mysql-legacy \

--env MYSQL_LEGACY_HOST=127.0.0.1 \ --env MYSQL_LEGACY_USER=legacy_reader \ --env MYSQL_LEGACY_PASSWORD=replace-with-a-secret \ --env MYSQL_LEGACY_DATABASE=legacy_app \ -- npx -y mysql-legacy-mcp

Codex

codex mcp add mysql-legacy \

--env MYSQL_LEGACY_HOST=127.0.0.1 \ --env MYSQL_LEGACY_USER=legacy_reader \ --env MYSQL_LEGACY_PASSWORD=replace-with-a-secret \ --env MYSQL_LEGACY_DATABASE=legacy_app \ -- npx -y mysql-legacy-mcp

Cursor and other clients

"mcpServers": { "mysql-legacy": { "type": "stdio", "command": "npx", "args": ["-y", "mysql-legacy-mcp"], "env": { "MYSQL_LEGACY_HOST": "127.0.0.1", "MYSQL_LEGACY_USER": "legacy_reader", "MYSQL_LEGACY_PASSWORD": "replace-with-a-secret", "MYSQL_LEGACY_DATABASE": "legacy_app" } } } }

Use the schema required by your client. Full copy-paste instructions for Claude Desktop, Codex, VS Code, Windsurf, Gemini, Trae, Qoder, and more are in the Installation guide.

Compatibility

MySQL	Status
5.0	Verified: 5.0.51a
5.1	Verified: 5.1.73
5.5	Verified: 5.5.62
5.6	Verified: 5.6.51
5.7	Verified reference only: 5.7.44
8.0	Not a target; default `caching_sha2_password` is unsupported

Each tested target passed all 11 tools — the 7 read-only tools plus the 4 opt-in write tools, with MYSQL_LEGACY_ALLOW_* flags checked both left at their default false and explicitly enabled — through a real MCP stdio session. On MySQL 5.6.5 and later, this also exercised the actual START TRANSACTION READ ONLY path used by mysql_legacy_select; below that version it exercised the silent plain-query fallback. Exact sources, test conditions, and the MySQL 8.0 boundary are recorded in the compatibility audit. This does not cover pre-4.1 old_password, custom connection charsets, TLS, or your server's exact patch level.

Compared with modern MySQL MCP servers

Server	Stated MySQL baseline	Focus
`mysql-legacy-mcp`	Verified live: 5.0–5.6	Legacy schema inspection and SELECT by default; opt-in INSERT/UPDATE/DELETE/DDL, with UPDATE/DELETE always requiring a WHERE clause
`@benborla29/mcp-server-mysql`	5.7+; 8.0+ recommended	Modern MySQL features such as TLS, SSH tunnels, and optional writes

This is a compatibility distinction, not a benchmark: choose the modern server for its modern-database features.

Features

Read-only SELECT tool with parser checks and result-size limits, wrapped in a read-only transaction on MySQL 5.6.5+
SHOW-based database, table, column, CREATE TABLE, and index inspection
Opt-in INSERT/UPDATE/DELETE/DDL tools, each disabled by default and gated by its own MYSQL_LEGACY_ALLOW_* flag; UPDATE and DELETE always require a WHERE clause
A small pooled set of MySQL connections (MYSQL_LEGACY_POOL_SIZE); no reliance on CTEs, JSON functions, or modern metadata columns

Tools

Tool	Purpose
`mysql_legacy_ping`	Return `VERSION()`
`mysql_legacy_select`	Run one parsed SELECT statement
`mysql_legacy_insert`	Run one INSERT statement (opt-in, `MYSQL_LEGACY_ALLOW_INSERT`)
`mysql_legacy_update`	Run one UPDATE statement with a required WHERE clause (opt-in, `MYSQL_LEGACY_ALLOW_UPDATE`)
`mysql_legacy_delete`	Run one DELETE statement with a required WHERE clause (opt-in, `MYSQL_LEGACY_ALLOW_DELETE`)
`mysql_legacy_ddl`	Run one table-level CREATE/ALTER/DROP/TRUNCATE/RENAME statement (opt-in, `MYSQL_LEGACY_ALLOW_DDL`)
`mysql_legacy_list_databases`	List databases
`mysql_legacy_list_tables`	List tables and views
`mysql_legacy_describe_table`	Show columns
`mysql_legacy_show_create_table`	Show table DDL
`mysql_legacy_list_indexes`	Show indexes

Documentation

Installation guide — client-specific setup
Configuration — environment variables, privileges, and security limits
Troubleshooting — authentication, TLS, encoding, and startup errors
Compatibility audit — reproducible version evidence
Roadmap — deliberately deferred work and why

Why this exists

This project came from a QA/fullstack workflow that needed AI-assisted inspection of a production MySQL 5.1 database. It is a focused utility for exploring legacy schemas and preparing migrations.

Contributing

See CONTRIBUTING.md for how to propose changes, run checks locally, and what evidence a compatibility claim needs. Quick start:
