Beacon MCP

Beacon is a neutral, verified-merchant index for AI shopping agents, specializing in regulated and age-gated commerce like alcohol. It provides earned-trust rankings based on public records, ensuring legal compliance and provenance without storing shopper data.

Endpoint and access

find_best_merchant
Advertised by the server during the last successful anonymous check.

Rank merchants that can actually fulfill a purchase need, by honest signals only. Args: category: product category, e.g. "vodka". ship_to: ISO region the order must ship to, e.g. "US-FL". require_age_gate: only return merchants that enforce 21+. limit: max results. optimize_for: what matters to the BUYER -- "trust" (default), "price" (lowest matched price), or "speed" (same-day, then next-day fulfillment). Ties always break by earned trust. product_type/dest_state/channel: pass all three (e.g. "spirits", "FL", "ship"|"local_delivery") for STRICT COMPLIANCE mode -- only merchants with attested age-gate + attested license + a legal jurisdiction path are returned, each with its compliance verdict. Every result carries ships_to states (match them against where the buyer lives), best_price, and the evidence behind the record. Paid placement never affects any ranking (ranking_basis states the basis actually used).

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http beacon-mcp-onrender https://beacon-index.onrender.com/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add beacon-mcp-onrender --url https://beacon-index.onrender.com/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable beacon-mcp-onrender in your MCP settings.

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
