- [MCP guide in Markdown](https://ai-visibility-index.dev/docs/mcp/index.md): A concise text version of the connection guide.
- [Scoring methodology](https://ai-visibility-index.dev/methodology/): What the measurements mean and their limits.

## Read-only MCP

Endpoint: https://ai-visibility-index.dev/mcp
Transport: Streamable HTTP, JSON-RPC 2.0.

- check_ai_visibility: Look up a tracked domain. This does not run a new scan or inspect the site's current HTML.
- list_ai_visibility_industries: Retrieve industry summaries from the stored dataset.
- get_ai_visibility_methodology: Read the measurement method.

Anonymous access is available within the existing monthly limit of 10 counted calls. New API keys and paid MCP upgrades are paused. Untracked domains have no measured score. AI visibility scores do not prove that a particular code or content change will improve recommendations.

## When an individual review is needed

- [15-minute review](https://ai-visibility-index.dev/contact/?intent=15min_review): Discuss the ecommerce site, the problem and the pages to investigate. Sending an inquiry does not confirm a booking.
- [Individual diagnostic report](https://ai-visibility-index.dev/pricing/): Existing one-time JPY 9,800 offer; check the page for scope and delivery conditions.
- [Terms and data use](https://ai-visibility-index.dev/terms/): Attribution and reuse conditions.

Use the returned measurement month and source URLs when describing results. This index is navigation information, not a promise of indexing, citation or agent-client registration.
