### Description (declared)

# WP Database MCP

MCP server for exploring WordPress MySQL/MariaDB databases — schema inspection, relationship
mapping, and raw SQL querying. It is read-only when you point it at a `SELECT`-only database
user, which is how it is meant to be run; see [Security](#security) for why that grant, rather
than anything in this process, is what makes it read-only.

## Features

- Auto-detects WordPress table prefix
- Full schema generation (JSON / CSV)
- WordPress relationship mapping (posts, terms, meta, users, comments)
- Raw SQL querying with SELECT-only validation as a guardrail (see [Security](#security))
- Automatic redaction of credential-shaped values (passwords, keys, tokens, secrets)
- Multisite support, including correct resolution of network-shared tables
- Query timeout (MySQL and MariaDB syntax both handled) and a configurable row cap
- Post search by title/content, with sane content-type/status defaults
- Startup audit of the database account's grants
- Extensible to plugin tables (WooCommerce, ACF, etc.)

## Security

**Read-only is enforced by the database grant, not by this server.** Create a MySQL/MariaDB
user that only has `SELECT`, and use that user's credentials. That grant is the actual
security boundary; everything else below is defence in depth on top of it.

### The SQL validator is a guardrail, not a boundary

`wp_query` runs every statement through `validate_select_only()` before execution. It rejects
non-`SELECT`/`SHOW`/`DESCRIBE`/`EXPLAIN` statements, DDL/DML keywords, filesystem/locking/timing
functions, `SHOW GRANTS`/`SHOW VARIABLES`, MySQL "executable comments" (`/*! ... */`), and access
to the `mysql`, `performance_schema`, and `sys` schemas. It is lexical analysis of a
language with a real grammar, and it exists to stop a confused model from firing off a
destructive statement by accident and to explain clearly why it was rejected. It is **not** a
sandbox a determined or malicious caller cannot escape.

Concretely: `aiomysql` unconditional…
