FLOPS Index

Official registry E-commerce

GPU rental reference prices (spot, on-demand, DePIN), key-free; every value carries a verify URL.

What can you do with FLOPS Index?

Five key-free tools — list_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).

Install

Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).

Remote (streamable-http)

Claude Code

claude mcp add --transport http flops-index 'https://app.flopsindex.com/mcp'

JSON configuration (Claude Desktop, Cursor, VS Code)

{
    "mcpServers": {
        "flops-index": {
            "type": "http",
            "url": "https://app.flopsindex.com/mcp"
        }
    }
}

PYPI package flopsindex-mcp

Claude Code

claude mcp add flops-index -e 'FLOPS_API_KEY=<your flops_api_key>' -- uvx flopsindex-mcp==0.12.5

JSON configuration (Claude Desktop, Cursor, VS Code)

{
    "mcpServers": {
        "flops-index": {
            "command": "uvx",
            "args": [
                "flopsindex-mcp==0.12.5"
            ],
            "env": {
                "FLOPS_API_KEY": "<your flops_api_key>"
            }
        }
    }
}

Environment variables

FLOPS_API_KEY secret Optional. Without it the five tools work key-free and return the delayed public value. A customer key is forwarded as the X-FLOPS-Api-Key header. Contact: team@flopsindex.com.

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.

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`.

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