MySQL MCP

io.github.gistrec/mcp-mysql-clientv1.0.1Databases

MCP server for one MySQL database: schema, read-only queries and guarded writes.

The current version, v1.0.1, was published to the official MCP registry on 2026-10-22. It is distributed as mcp-mysql-client on npm, filed under Databases by this index, and declares 12 environment variables. Removals and unreachable sources are measured across every server this index tracks, contract drift across the servers that answer in consecutive snapshots; the index's current counts put this record in context.

In-path gate · all MCP tools

Using MySQL MCP in Claude, Cursor, Gemini CLI, Cline, or Zed?

MCP tool contracts can change remotely with no version bump. The mcpindex gate pins each contract and HOLDs the call when it drifts-before your agent acts. Zero credentials. This is not the package install for this server itself (use Install this server for that).

Install the mcpindex gate (one command)

Rewrites your MCP host config so each server launches behind the gate. Inspect first: curl -fsSL https://mcpindex.ai/install.sh | less

Limits of this verdict

- Semantic screen only - the deterministic conformance probe has not run on this server
- Confidence is reported but not yet calibrated (v1)
- Screen reads the tool description, not the live behavior
- advisory
- registry description only no input schema
- screen model 8b
- Still current: the description we screened is unchanged, re-checked against the registry
- The registry listing (version, packages, links) changed after this screen ran - the description we assessed did not

Semantic screen: an LLM judge reads the tool description for hidden instructions (status PARTIAL). A pass means the description is not lying, not that the tool is safe: a high-capability tool with an honest description still warrants caution. The deterministic conformance probe has not been run on this server yet, so the screen here is semantic-only. Posture: advisory. Confidences are reported but not yet calibrated (calibrated=false at v1). Full verdict history is not shown on this page.

Own this server? Test a description on the public screen → It is a separate check from the verdict above, so the two can differ.

That verdict was true at screening time (snapshot 2026-10-23).

Contracts can change after screening, with no version bump. The gate pins MySQL MCP’s tool contracts on first sight and holds any silent change before your agent acts - the check that keeps being true on Tuesday.

Cite this record

People vet a server before wiring it in. One line on your project site or docs answers that with an independent record: screening verdict, registry provenance, contract drift history. It stays current as new screens and drift events land.

Environment variables

MYSQL_HOST

Database host.

MYSQL_PORT

Database port.

MYSQL_USER

required

MySQL user. Use one with the least privileges the task needs, never root.

MYSQL_PASS

secret

Password for that user. Treat it as a secret; MYSQL_PASS_FILE reads it from a file instead.

MYSQL_DB

required

The one database this server is bound to. No tool can leave it.

MYSQL_SSL

Require a TLS connection to the server.

MYSQL_SSL_CA

Path to the CA bundle verifying the server certificate; implies MYSQL_SSL.

ALLOW_INSERT_OPERATION

Allow INSERT statements through the execute tool.

ALLOW_UPDATE_OPERATION

Allow UPDATE statements through the execute tool.

ALLOW_DELETE_OPERATION

Allow DELETE statements through the execute tool.

MYSQL_MAX_ROWS

Row cap for one read; the result is marked truncated when it is hit.

MYSQL_TIMEOUT_MS

Statement timeout in milliseconds; the connection is dropped on expiry.

Verdict API

Free-tier verdict as JSON: decision + dimensions + severity. Call it from your agent before it invokes a tool it just discovered.

Provenance

Each verdict is bound to a hash of the exact description it judged, so a re-crawl that changes the text produces a new record rather than silently inheriting this one. Verdict history is hash-chained and anchored to Bitcoin via OpenTimestamps (latest confirmed at block 972,713). Verify it yourself.
