AlphaBridge MCP – Connect Claude and ChatGPT to WordPress: MCP server with permissions per connection and audit log

Description

Connect Claude and ChatGPT to WordPress — with the rights you choose.

AlphaBridge MCP turns your WordPress site into a native MCP server (Model Context Protocol). An AI assistant such as Claude — on Claude.ai, in Claude Desktop, Claude Code or Cursor — connects over one authenticated HTTPS endpoint and manages content, media, taxonomies, comments, widgets and site settings through structured tools that check WordPress permissions on every single call. ChatGPT connects the same way, as an MCP app on the Plus, Pro, Business, Enterprise and Edu plans. Tell Claude what you want done — “draft a post from these notes, add last week’s photos, file it under the right categories and schedule it for Friday” — and it happens on your site, not through screen-clicking or raw admin access.

You stay in control

Handing an AI the keys to your site should feel safe — so control comes first:

• Every connection acts as a real WordPress user, and every tool checks the matching WordPress capability. What that user may not do, the AI cannot do.
• Scoped connections: hand out a read-only or content-only key with an optional expiry instead of full access. Rotate a connection’s secret in one click.
• Tool groups you can switch off entirely — disabled tools vanish from the MCP surface. Plus a global read-only mode.
• An audit log records every tool call, and a fixed rate limit stops abusive request bursts.

Connected in two minutes

In Claude, connect «AlphaBridge MCP for WordPress» from the connector directory, enter your site’s address and approve on your own site’s login-protected consent screen — no address or token to copy (standard OAuth 2.1 with PKCE; the login is your WordPress login, no account with us). That entry runs through the AlphaBridge Connect hub described below; to connect directly, paste your endpoint URL into Claude as a custom connector instead. For clients without a Connect button, create a token manually and paste one ready-made config. ChatGPT connects the same way: add the endpoint as an MCP app (Plugins → Add → Create MCP app, authentication OAuth) and approve on your site — checked on 26 September 2026 with ChatGPT Pro, directly and through the hub.

The whole way in one minute — install, connect from Claude’s directory, approve on your site, give Claude a first task:

In German: Claude mit WordPress verbinden

AlphaBridge Connect — the optional hub

The entry «AlphaBridge MCP for WordPress» in Claude’s connector directory is the hosted hub at connect.alphabridge-mcp.com: you enter your site’s address instead of copying the endpoint, and you approve the site on its own login screen. The site keeps its own rights and its own audit log. Through the hub, up to 10 sites work from one chat, in every edition including this free plugin: add a site from the chat and keep working in the same conversation. The hub is optional and free, and this plugin never contacts it on its own — the hub connects to your site for authorization, connection setup and management, and to forward the tool calls you make through it. It stores the site’s access key encrypted and passes content through without storing it; the details are in its privacy notice (https://connect.alphabridge-mcp.com/legal/privacy) and its data processing agreement (https://connect.alphabridge-mcp.com/legal/dpa).

Nothing extra to host

Unlike bridge-based solutions, AlphaBridge speaks MCP directly in PHP inside WordPress. With a direct connection there is no Node middleware, no external service and nothing else to run or pay for — it works on ordinary WordPress hosting, which makes it faster and more stable. The hub above is the one optional exception, and you choose whether to use it.

Free means free

Everything in this plugin is fully functional: no license keys, no registration, no plan-based, cumulative or time-based usage limits, no locked features.

What’s inside

• Native MCP endpoint (JSON-RPC 2.0 over HTTP POST; protocol versions 2024-11-05, 2025-03-26, 2025-06-18) — no external server required.
• 39 structured tools across content, media, taxonomies, comments, widgets, site settings, site info, SEO reads and search.
• Bearer-token authentication mapped to a real WordPress user, with per-tool capability checks.
• Unlimited connections — create one deliberately limited key per client.

How it compares

Need more? A separate commercial add-on, AlphaBridge MCP Pro, adds tool groups for the database, users, plugin and theme files, WooCommerce and migration, plus an undo for changes made through it (undo points expire after 24 hours). The Agency plan adds Site Deploy: files, themes and whole builds published onto your own hosting over SFTP; ZIP deploys can run atomically, with rollback when the swap fails. Both are entirely optional — this free plugin is complete on its own and stays fully functional without them. Details are on the plugin website.

AlphaBridge is our own product brand for this project. MCP (Model Context Protocol) is an open protocol standard; this plugin is an independent implementation and is not affiliated with or endorsed by the protocol’s authors or by any other vendor.

External services

This plugin makes no automatic outbound requests and sends no telemetry. One tool can contact an external address, and only on your explicit instruction: when you call wp_upload_media_from_url with a URL, the plugin downloads that file from the address you provide (and up to a few safely re-validated redirects; SSRF-guarded, type- and size-checked). The plugin itself initiates no other outbound requests.
