  • compare_coffeesFree

    Side-by-side comparison: roast, body/acidity/sweetness, shared and distinct flavors, brew methods, and price difference.

  • dial_in_suggestionFree

    Brew guidance for a specific coffee: curated recipes from the Percolate catalog (ratio, temperature, grind) when available, or a roast-based starting point. Optionally scoped to your brew method.

  • find_similarFree

    Coffees with a similar profile to a given one, ranked by shared flavor notes and roast/body/acidity/sweetness proximity. Deterministic scoring over Percolate's structured tasting data.

  • get_coffeeFree

    Detailed record for one coffee: roast level, body/acidity/sweetness profile, flavor notes, suited brew methods, food and brew pairings, price, and retailer links. Accepts a Percolate id or a name.

  • get_recommendationsFree

    Personalized coffee picks from flavor preferences (e.g. 'chocolate', 'berry', 'caramel'), a budget in USD, roast preference, and the brew gear you own.

  • search_coffeesFree

    Search 1,100+ curated specialty coffees in the Percolate database. Filter by category (espresso, single_origin, blend, decaf, dark), roast level, brew method, and price (USD). Returns tasting profiles, brew methods, and where-to-buy links.

  • trending_coffeesFree

    Coffees Percolate users are adding to their collections most over the last 30 days (falls back to catalog popularity when live activity data is unavailable). The method used is labeled in the response.

  • what_to_brewFree

    A coffee suggestion for right now, based on time of day (evening picks lean decaf), mood, and the brew method you're using — scored over Percolate's tasting profiles.

What the publisher says

From the Percolate repository's README, as published. We do not edit it. Read it on GitHub

Percolate MCP Server

Query the Percolate specialty coffee database from Claude, or any MCP-compatible AI client. Read-only access to 1,100+ curated coffees with tasting profiles, brew recipes, pairings, and where-to-buy links.

Percolate is the specialty coffee journal for iOS — get it on the App Store.

Tools

Every response includes source attribution, a citation-ready summary line, links, and data freshness dates. All scoring is deterministic — no AI calls happen inside the server. All tools are annotated read-only/idempotent.

Install (Claude Desktop)

Requires Node.js 18+.

Add to your claudedesktopconfig.json (Claude Desktop → Settings → Developer → Edit Config):

{
  "mcpServers": {
    "percolate": {
      "command": "npx",
      "args": ["-y", "percolate-mcp"]
    }
  }
}

Restart Claude Desktop. No API key or configuration needed — the server ships with public read-only access.

Configuration (optional)

Environment variables override the defaults (explicit env vars only — this package never reads .env files):

Without the service key, trending_coffees falls back to catalog popularity and labels the method in its response.

Remote endpoint (no install)

Streamable HTTP for web agents and MCP clients that take a URL:

https://wmpiabzlcaqyrzxvfihi.supabase.co/functions/v1/mcp

Also listed on Smithery and the official MCP registry as io.github.bguillow-rgb/percolate.

Example agent requests

Questions an agent can answer with these tools:

  • "Recommend a medium roast with chocolate and nutty notes." → getrecommendations with preferences: ["chocolate","nutty"], roastlevel: "medium"
  • "How should I brew this Onyx Monarch on a V60?" → dialinsuggestion (curated recipes: ratio, temperature, grind)
  • "What coffee works for espresso under $20?" → searchcoffees with brewmethod: "espresso", price_max: 20
  • "What should I brew tonight?" → whattobrew (evening picks lean decaf automatically)
  • "Find me something similar to this Ethiopian natural." → find_similar
  • "Compare these two bags." → compare_coffees

Example response shape (truncated):

{
  "method": "curated_pairing",
  "recipes": [
    { "recipe": "Pour-over (V60), 1:16, 205°F",
      "why": "clarity that lets the delicate, high-acid notes open up" }
  ],
  "attribution": {
    "source": "Percolate — Specialty Coffee Journal",
    "links": { "website": "https://percolateapp.com/" }
  }
}
