Assess passage width and flow

The `check_corridor_and_passage` tool takes a path blueprint and returns compliance status, detailing specific violations. You can instantly verify if any corridor or general walkway meets the minimum clear width required for universal access. This is critical work when reviewing blueprints. It tells you exactly where clearances fall short of established standards.

Review ramp slopes and bathroom space

Need to verify a challenging area? Use `check_ramp_compliance` to confirm if a ramp section holds to the maximum 33% slope limit, plus required transition landings. For restrooms, the tool also confirms that the available space meets functional requirements for mobility aid maneuverability. These checks let you compare current architectural plans against stringent USA/EU standards without leaving your chat window.

Verify entry points

Every entrance needs proper clearance. The `check_doorway` function assesses the clear opening width, making sure it's big enough for mobility aid users to pass through easily. It’s a quick check that prevents major compliance headaches later on. Run this before you approve any final structural drawings.

Common questions about Accessibility Checker MCP in Claude Desktop

It runs as a tool in your local environment. You just call it through the chat, and it uses its connection to analyze structural data locally before sending you the report.

Yep. As long as you can feed the dimensions into your local setup, this MCP handles comparison against current USA/EU standards for corridors and ramps.

It focuses on core universal accessibility elements: passages, doorways, ramps, and rest areas. It checks compliance based on structural dimensions, not occupancy type.

The tool analyzes dimensional data from blueprints, including clear passage widths, ramp slopes, and doorway openings.

Your credentials are handled by Vinkius zero-trust proxy. The tool only processes structural dimensions, such as measured clear passage widths and ramp gradients.
