Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

resy scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

resy-mcp

MCP server for Resy — natural-language restaurant reservation management. Uses Resy's private web-app API with email + password auth.

⚠️ Resy does not publish an official API. This server uses the same private endpoints the Resy web app calls, with the public web-app api_key and user-level auth via email + password. Use at your own discretion.

Setup

Option A — npx (recommended)

Add to .mcp.json in your project or ~/.claude/mcp.json:

{
  "mcpServers": {
    "resy": {
      "command": "npx",
      "args": ["-y", "resy-mcp"],
      "env": {
        "RESY_EMAIL": "[email protected]",
        "RESY_PASSWORD": "yourpassword"
      }
    }
  }
}

Option B — from source

git clone https://github.com/chrischall/resy-mcp
cd resy-mcp
npm install && npm run build

Then add to .mcp.json:

{
  "mcpServers": {
    "resy": {
      "command": "node",
      "args": ["/path/to/resy-mcp/dist/bundle.js"],
      "env": {
        "RESY_EMAIL": "[email protected]",
        "RESY_PASSWORD": "yourpassword"
      }
    }
  }
}

Or place .env in the project directory with RESY_EMAIL= and RESY_PASSWORD=.

Authentication

  • RESY_EMAIL + RESY_PASSWORD are required. The client logs in lazily on first request via POST /3/auth/password, caches the returned token for the process lifetime, and re-logs automatically on 401 / 419 / auth-like 500 responses.
  • RESY_API_KEY is optional. If unset, the client uses the public web-app key baked into resy.com's JS bundle. Override only if Resy rotates it.

Tools

User

Tool Description
resy_get_profile(view?) Current user profile — name, email, phone, booking count, member-since. Payment method IDs are stripped.
resy_list_payment_methods(view?) List saved payment methods (id, brand, last_four, exp_month, exp_year, is_default). The id feeds resy_book's payment_method_id.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
