Graviti MCP server

What it does

Graviti is an MCP server that exposes a deterministic brand-ranking engine for agent-mediated commerce. It provides tools for matching user intent to verified brands, retrieving accountability logs, and inspecting a hash-chained, signed ledger of index history. It is aimed at AI agents and developers who need auditable, non-pay-to-rank product recommendations.

• Query the engine with a natural-language product question and receive ranked brand matches with disclosed scoring metadata.
• Retrieve verified claims and accountability logs for specific brands to check what has been independently audited.
• Inspect the category landscape or gap report to identify which product categories have verified coverage and where gaps exist.

Before you enable it

An MCP server runs with whatever access you give it. Start with a development account rather than production, and check which tools the server exposes before you let an agent call them unattended.
