WordPress MCP Extension for VS Code

The WordPress MCP Extension turns a standard Visual Studio Code session into an AI‑powered WordPress development environment. By exposing the WordPress configuration, database, and code context through the Model Context Protocol (MCP), it lets AI assistants such as Claude or ChatGPT query and manipulate a site’s data directly from the editor. This eliminates the need for separate debugging tools or manual look‑ups, enabling developers to ask natural language questions and receive instant, context‑aware answers.

Solving Real Development Pain Points

When building or maintaining WordPress themes and plugins, developers routinely flip between the editor, a local server, the database, and documentation. The MCP extension resolves this friction by automatically discovering the file, extracting credentials, and establishing a live database connection. Once connected, the AI client can perform queries—such as listing active plugins or retrieving the current theme—and provide code completions that reflect the exact version of WordPress installed. This reduces context switching, speeds up debugging, and lowers the barrier to entry for newcomers who may not be familiar with WordPress internals.

Core Capabilities

• Automatic Environment Detection: The server walks up the directory tree to locate , ensuring it works in nested projects or multi‑site setups.
• Live Database Access: Credentials extracted from the configuration file are used to open a connection, allowing AI queries that read or modify data in real time.
• Context‑Aware Autocompletion: As the developer types, the MCP server supplies function names, hooks, and class methods that are relevant to the current WordPress version.
• Hover Documentation: Hovering over a function or hook shows up‑to‑date documentation, including signature and version information.
• Code Actions: Quick fixes and refactorings tailored to WordPress conventions are offered through the editor’s context menu.

Use Cases in Practice

• Dynamic Schema Exploration: “@wordpress What custom post types are available?” instantly returns a list derived from the database.
• Configuration Auditing: “What is the database name in wp-config.php?” or “Show me active plugins” can be answered without opening files manually.
• Rapid Prototyping: Developers can prototype plugin logic by querying the database or inserting sample data, all within a single editor session.
• Education & Onboarding: New contributors can learn about the site’s structure through AI‑guided queries, speeding up their ramp‑up time.

Integration into AI Workflows

The server exposes standard MCP resources—tools, prompts, and sampling—to any AI client that supports the protocol. Once a VS Code session is connected, an assistant can issue commands like or use the chat interface with a prefix such as . The assistant receives structured responses (e.g., JSON tables) that can be rendered directly in the editor or used to trigger further actions. Because the server runs inside VS Code, it inherits the same authentication and permission context as the developer, ensuring secure access to sensitive data.

Standout Advantages

• Zero‑Configuration Setup: No additional settings are required; the extension auto‑detects the WordPress installation.
• Version Sensitivity: Completion and documentation are tied to the specific WordPress version detected, preventing mismatches between local code and remote sites.
• Seamless Extension: Works alongside existing VS Code extensions, enhancing rather than replacing current workflows.
• Open‑Source Flexibility: Developers can fork the extension to add custom MCP commands, tailoring it to bespoke workflows or multi‑site architectures.

In summary, the WordPress MCP Extension empowers developers to harness AI assistance directly within their familiar coding environment. By bridging the gap between editor, database, and WordPress API, it delivers a cohesive, efficient workflow that accelerates development, debugging, and learning.
