Security Report

5.2

Moderate5.2Moderate Risk

A well-architected MCP server for public GPU pricing data with strong security practices. Authentication is optional (anonymous access works) but properly implemented via environment variables when provided. Code is clean, input validation is present, and permissions are appropriately scoped to network access and environment variables only. No malicious patterns, hardcoded secrets, or dangerous operations detected. Supply chain analysis found 3 known vulnerabilities in dependencies (0 critical, 3 high severity). Package verification found 1 issue.

Security scores are indicators to help you make informed decisions, not guarantees. Always review permissions before connecting any MCP server.

Permissions Required

This plugin requests these system permissions. Most are normal for its category.

HTTP Network Access

Connects to external APIs or services over the internet.

env_vars

Check that this permission is expected for this type of plugin.

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"
    }
  }

From the project's GitHub README.

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-SPOT / FLOPS-OD / FLOPS-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.
Keyed (X-FLOPS-Api-Key) → the same five tools at full precision.

A partner tier with higher fidelity and expanded coverage is available — contact team@flopsindex.com.

What's in this repo

Path	What
`mcp/`	The `flopsindex-mcp` server — stdio MCP, 5 public tools (`list_indices` · `search_indices` · `get_price` · `get_index` · `verify`) + a `flops://index/<INDEX_ID>` resource. Published on PyPI.
`sdk/python/`	The `flopsindex` Python REST SDK — published on PyPI.
`sdk/typescript/`	The `@flopsindex/sdk` TypeScript / JavaScript REST SDK — published on npm.
`schema/`	`compute-index-spec.v0.1` — the public payload schema (JSON Schema) + a worked example.
`openapi.json`	OpenAPI 3 description of the public surface.
`llms-full.txt`	Extended public-surface reference for LLM/agent discovery — source-opaque, 6 endpoints, 14-field envelope. Mirror of the hosted `/llms-full.txt`.

Verify a value yourself

curl -s https://app.flopsindex.com/v1/price/FLOPS-H100-OD | jq
#   value:            2.95            (USD/GPU-hr, 2dp)
#   unit:             USD/GPU-hr
#   as_of:            2026-07-13T12:00:00Z   (delayed to a ~6h grid: 00/06/12/18 UTC)
#   data_tier:        LIVE
#   confidence:       HIGH            (HIGH | MED, label only)
#   change_24h:       FLAT            (banded: UP | FLAT | DOWN)
#   disclaimer:       indicative reference; not for settlement
#   methodology_url:  /i/FLOPS-H100-OD/methodology
#   verify_url:       /v1/verify?...
#   citation_url:     /cite?...
#   permalink:        /i/FLOPS-H100-OD
#   ... source-opaque public payload only.

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