About

Security Report

5.2
Moderate5.2Moderate Risk

A well-engineered MCP server for GPU compute pricing with strong security practices. Authentication is properly optional (anonymous access for public data, API key support via environment variables). Input validation is thorough—index IDs are regex-validated and percent-encoded before use, preventing path traversal. Code quality is high with comprehensive test coverage, proper error handling, and no credential leakage. Permissions are appropriate for the server's purpose (HTTP API calls to a pricing service). Minor findings around broad exception handling and logging are low-severity. Supply chain analysis found 5 known vulnerabilities in dependencies (0 critical, 5 high severity). Package verification found 1 issue.

What You'll Need

Set these up before or after installing:

Optional API key that upgrades the five public tools (list_indices, search_indices, get_price, get_index, verify) to full-precision values. Without it the tools work key-free and return the delayed public price. Forwarded as the X-FLOPS-Api-Key header. A partner tier with higher fidelity and expanded coverage is available — contact team@flopsindex.com.Required

Environment variable: FLOPS_API_KEY

How to Install

Add this to your MCP configuration file:

{
  "mcpServers": {
    "io-github-zeroatflops-flopsindex-mcp": {
      "env": {
        "FLOPS_API_KEY": "your-flops-api-key-here"
      },
      "args": [
        "flopsindex-mcp"
      ],
      "command": "uvx"
    }
  }
}

flopsindex

Reference rates for compute economics — public price indices for GPU rentals (spot, on-demand, DePIN). Every published value carries a verify URL your code can check against the public index.

Try it in one line

# MCP server (Claude Code, Cursor, Windsurf, ChatGPT desktop, ...)
pip install flopsindex-mcp && claude mcp add flopsindex -- flopsindex-mcp

# Python REST SDK
pip install flopsindex

# TypeScript / JavaScript SDK
npm i @flopsindex/sdk

# Or skip install — hit the hosted MCP gateway
# https://app.flopsindex.com/mcp   (anonymous, zero-config)

Or to your agent: "Get me the current FLOPS price for an H100 on-demand and show me the verify URL."


What's distinctive

Source-opaque by contract. Every public payload returns a value plus citation and verify URLs — nothing about how the value was produced.

One surface, two access modes.

  • Anonymous → delayed public price for the published FLOPS index family (FLOPS-{model}-{OD|SPOT|DEPIN}), delayed onto a ~6h grid (as_of snaps to 00/06/12/18 UTC). Indicative reference — not for settlement. The citation surface, designed for LLM/agent discovery and academic reference. The family spans many accelerator models (NVIDIA data-center and workstation GPUs plus AMD Instinct), not just H100 — enumerate the live set via /v2/catalog/public; it grows as coverage crosses the ≥3-source floor.
  • Keyed (X-FLOPS-Api-Key) → the same five tools at full precision.

Features

  • Five key-free toolslist_indices, search_indices, get_price, get_index, verify. No API key, no signup, no configuration.
  • Every value carries a verify URL — check any published number against the index from your own code. verify returns whether a cited value matches.
  • Spot, on-demand and DePIN reference prices per chip and market type.
  • Three vendors — NVIDIA data-center and workstation GPUs, AMD MI300X, and Intel Gaudi 2. Enumerate the live set via /v2/catalog/public.
  • Source-opaque by contract — the value plus citation and verify links, never the inputs behind it.
  • Delayed onto a ~6h grid (00/06/12/18 UTC), 2dp values, banded 24h change, label confidence. Indicative reference — not for settlement.
  • Zero install or local — hosted MCP gateway at https://app.flopsindex.com/mcp, or uvx flopsindex-mcp.
  • SDKs included — Python (flopsindex), TypeScript (@flopsindex/sdk), and LangChain / LlamaIndex (langchain-flopsindex).

The same value is reachable via the SDK and via the MCP get_index tool — every path returns the same source-opaque payload.
