MySQL / MariaDB + Claude

Prerequisites

See the full setup instructions baked into the connector (visible in the in-app store when you select the connector). The required environment variables for this connector are:

MYSQL_HOST, MYSQL_PORT, MYSQL_DATABASE, MYSQL_USER, MYSQL_PASSWORD

Step 1 — Get credentials

Setup

  1. Create a dedicated user and grant it only SELECT:
    CREATE USER 'amcp_reader'@'%' IDENTIFIED BY 'change-me';
    GRANT SELECT ON sales.* TO 'amcp_reader'@'%';
    FLUSH PRIVILEGES;
    
    Narrow '%' to the AnythingMCP host if you can — MySQL's host part of the account name is a real access control and worth using.
  2. Set MYSQL_HOST, MYSQL_PORT (3306), MYSQL_DATABASE, MYSQL_USER and MYSQL_PASSWORD.

MariaDB works unchanged. The engine also accepts a mariadb:// DSN and normalises it, because the mysql2 driver only understands mysql://. Either scheme reaches a MariaDB server.

…(continued in the in-app connector instructions)

Step 2 — Install the adapter

curl -fsSL https://raw.githubusercontent.com/HelpCode-ai/anythingmcp/main/docker-compose.quickstart.yml -o docker-compose.yml
printf 'JWT_SECRET=%s\nENCRYPTION_KEY=%s\n' "$(openssl rand -hex 32)" "$(openssl rand -hex 32)" > .env
docker compose up -d

Step 3 — Add the connector in Claude

Recommended path — works on claude.ai web without editing any config file.

  1. Open claude.ai/customize/connectors.
  2. Click "Add custom connector".
  3. Fill in:
    • Name: MySQL / MariaDB
    • URL: https://cloud.anythingmcp.com/mcp
    • Authentication: Bearer token → paste your MCP API key (from AnythingMCP → Profile → MCP API Keys → New Key)
  4. Click Connect to authorize.
