What it can do

Tool names and descriptions exactly as the server reported them on Nov 8, 2026. The maker wrote them, not us; we show them as plain text.

  • list_indices

    List all public FLOPS compute-price indices. Returns {count, indices[]} where each row is {index_id, family, value, unit, as_of, confidence, change_24h, delayed}. Use this to discover available indices before calling get_price or verify. No auth required.

  • verify

    Check a FLOPS index value against the published index. Pass `value` with a number you are about to cite (or already hold) and the response tells you whether it is right: `verified` true/false, `expected` (what you submitted), `actual_value` (what FLOPS publishes) and `delta_pct`.

  • get_price

    Fetch the current published value for a FLOPS compute price index. Returns {value, unit, as_of, data_tier, confidence, verify_url, citation_url}. Cheapest way to answer 'what is the latest public reference price for X?' (refreshed every 6 hours). Confidence is a label (HIGH or ME

  • search_indices

    Resolve a free-text query to canonical FLOPS index slugs. Use when you don't know the exact slug — e.g. 'H100 spot' returns the matching SPOT family entries. Best paired with get_price to look up + quote a value in one turn.

  • get_index

    Resolve a FLOPS index to its source-opaque PUBLIC citation payload. Returns exactly {index_id, value, unit, as_of, data_tier, confidence, methodology_url, verify_url, citation_url, permalink} — no source-level detail. Prefer get_index when you intend to CITE the value.

  • share_feedback

    Optional. Tell the FLOPS team what this data is used for, what was missing, or whether an hourly-refreshed feed would be worth paying for. Would you or your user pay for fresher FLOPS data? If not, why not (field why_not)? Only include what your user is comfortable sharing; no pe

Common questions

Is FLOPS Index safe?

It passed 4 of 4 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: FLOPS_API_KEY

Does it run on my computer or in the cloud?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed 27 days ago, and the latest version (0.12.5) reached the registry 27 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT Business and above.

What can I use instead?

In the same category: World Monitor, Claude Flow, Tldraw

MCP server for the FLOPS public compute price indices — catalog, search, price lookup, and verification over stdio. Works with Claude, Cursor, Windsurf, or any MCP-capable host.

Monorepo — flopsindex · Public access overview

Public access

This package exposes the public FLOPS index surface only: citeable reference rates with verify and permalink URLs. Index construction methodology is not published in this repository — see flopsindex.com and the public access overview.

AccessWhat you getHow (this package)
Anonymous (default)Delayed public price (~6h grid; indicative, not for settlement) for the FLOPS family — spot, on-demand and DePIN market types, e.g. FLOPS-H100-OD, FLOPS-A100-SPOT, FLOPS-A100-DEPIN. Built for agents, citation, and lookup.No API key — stdio server or hosted /mcp
KeyedSame five tools at real-time, full precision.Set FLOPS_API_KEY (forwarded as X-FLOPS-Api-Key)
PartnerHigher fidelity, expanded coverage, and additional detail beyond the public delayed surface.team@flopsindex.com

If you need more than delayed public rates — e.g. production-grade latency, broader index families, or deeper commercial terms — reach out to team@flopsindex.com to discuss partner options.

Tools

Five public, key-free tools:

ToolDescription
list_indicesEnumerate all public FLOPS indices. Optional family_filter substring (e.g. FLOPS-H100).
search_indicesFree-text search across the public catalog (resolves to slugs).
get_priceLatest published price + confidence for one index.
get_indexSource-opaque public payload — the citation shape (index_id, value, unit, as_of, data_tier, confidence, verify_url, citation_url, permalink). Use this when you intend to cite a value.
verifyLatest published value + verify metadata for a given index_id.

Resources

Every public index is also exposed as an MCP resource:

URIReturns
flops://index/ Same source-opaque payload as get_index, mimeType: application/json.

list_resources enumerates one entry per catalog index; read_resource("flops://index/FLOPS-H100-OD") resolves the live value.

Install

uv tool install flopsindex-mcp

or

pip install flopsindex-mcp

Setup

Point your MCP host at the server. Config file location depends on the client (Claude Code, Cursor, Windsurf, etc.):

{

"mcpServers": { "flopsindex": { "command": "flopsindex-mcp" } } }

Or use the hosted gateway at https://app.flopsindex.com/mcp — same five tools, no local install.
