Microsoft Access Database

mcp-access

Give any AI assistant full control over Microsoft Access databases.

Create forms, write VBA, design tables, manage controls, run queries, build relationships, and edit every corner of an .accdb — all through natural language. 69 tools that turn Access into something you can *talk to*.

No Access expertise required. Just describe what you want.

"Create a form called Invoices with a ListBox, two date filters, and a search button"

"Add a VBA click handler that filters the recordsource by date range" "Create a table called audit_log with timestamp, user, and action fields" "List all controls inside the Payment tab and change the combo's row source"

The AI handles the COM automation, design view, VBA modules, binary sections, cache invalidation, and all the ugly parts. You get the result.

What it can do

• Forms & Reports — create, clone, export, import, screenshot, click, type. Full UI automation loop
• VBA — read, write, replace, compile, and *run* procedures. Line-level or full-proc editing
• Controls — create, delete, modify, list, set tab order. Finds controls nested inside TabControl pages
• Tables & SQL — create via DAO, alter, query, batch execute, full-text search across every Text/Memo field. Linked ODBC tables supported
• Relationships, indexes, references, queries, macros — full CRUD. Clone any object (form / report / module / class / query / macro) preserving VBA and binary sections
• Maintenance — compact & repair, decompile bloated databases, export structure docs. Office install autodetected (no more hardcoded Office 16 paths)
• UI lint — access_lint_form flags *objectively* broken layouts (white-on-white text, overlaps, truncation, off-canvas controls). A checker, not a designer — see the note below

Works with Claude Code, Cursor, Windsurf, Continue, or any MCP-compatible client.

Requirements

• Windows (COM automation is Windows-only)
• Microsoft Access installed (any version that supports VBE, 2010+)
• Python 3.10+
• *"Trust access to the VBA project object model"* enabled in Access Trust Center

Installation

pip install "mcp>=1.0.0,<2" pywin32 pillow

Enable VBA object model access

File → Options → Trust Center → Trust Center Settings → Macro Settings → check Trust access to the VBA project object model

Or run the included PowerShell script:

.\enable_vba_trust.ps1

Register with Claude Code

Global (available in all projects):

claude mcp add access -- python C:\path\to\access_mcp_server.py

Project-only (creates .mcp.json in current directory):

claude mcp add --scope project access -- python C:\path\to\access_mcp_server.py

Register with other MCP clients

Add to your MCP config file (.mcp.json, mcp.json, or client-specific settings):

{

"mcpServers": { "access": { "type": "stdio", "command": "python", "args": ["C:\\path\\to\\access_mcp_server.py"] } } }

Compatible with any MCP-compliant client (Cursor, Windsurf, Continue, etc.).

### ⚠️ A note on access_lint_form — manage your expectations

This is NOT a designer and there is zero super-design here. Don't expect it to make a form *look good*, suggest a nice palette, or have any taste — it has none and never will.

It is a dumb, deterministic verifier of the obvious, easy-to-check stuff: is the text the same colour as its background? do two controls physically overlap? does a caption not fit its box? is something off the edge of the form, or zero pixels tall? That's it. Plain math — WCAG contrast ratios and rectangle intersection — with a pile of false-positive guards so it doesn't cry wolf.

Think seatbelt, not stylist: it won't make the car pretty, it just stops you shipping a form with white text on a white background without noticing. It runs automatically on every control edit so those obvious mistakes surface on their own. If you were hoping for a UI-design AI, this isn't it (honest PRs to make it smarter are very welcome 😄).
