simple-mysql-mcp-server
Provides an MCP server that exposes “simple” MySQL connectivity as agent-callable tools (for querying/updating a MySQL database) with configuration supplied by the host environment.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Security depends heavily on how the MCP server is deployed: DB creds must be protected, ideally with read-only accounts; tool-level authorization/SQL allow-lists and parameterization are critical to prevent destructive or exfiltrating queries. TLS enforcement and secret handling cannot be confirmed from the provided information.
⚡ Reliability
Best When
You have an internal MySQL instance, you can control access/credentials, and you want an agent to perform database reads (and optionally constrained writes) via MCP tools.
Avoid When
You cannot restrict the agent from issuing harmful SQL (DROP/DELETE/UPDATE), or you lack secure network/credential handling; avoid exposing the MCP server broadly.
Use Cases
- • Let an LLM/agent read from a MySQL database to answer questions
- • Generate and run SQL for reporting/diagnostics with controlled access
- • Automate lightweight data retrieval tasks from existing operational databases
Not For
- • Running arbitrary destructive SQL in a production database without strong safeguards
- • Handling sensitive regulated data without compensating controls
- • Multi-tenant or internet-exposed use cases where DB credentials and access need strict isolation
Interface
Authentication
No OAuth-style auth indicated; security is likely delegated to DB credentials and network access. Fine-grained tool-level authorization/scopes are not evidenced from the provided information.
Pricing
Open-source package; no pricing info.
Agent Metadata
Known Gotchas
- ⚠ Agents may attempt to run unsafe/non-parameterized SQL; enforce allow-lists and read-only credentials where possible.
- ⚠ Agents may hallucinate schema/columns; require schema introspection or provide schema context.
- ⚠ If the MCP server does not clearly surface SQL errors, agents may repeatedly retry failing queries without improvement.
