## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-10-18.

- **Endpoint Security**: 80/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 73/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 727 tokens (~145/item across 5 items; 5 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 13/100
  - Stability observed for 4 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 95/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 86% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 5 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 6 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

## Install

### How do I install the FLOPS Index MCP server?

FLOPS Index is a hosted endpoint at https://app.flopsindex.com/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-10-17 (score 73, +1)

No change was recorded against any check on this day. Stability & Change Management went from 7 to 10. That category is still filling its 30-day observation window: 2 days of observed history at the previous scan, 3 at this one. The score rises as the window fills, whether or not the server changes.

### 2026-10-15 (score 72, +8)

- [security improvement] Authorization: unverified → partial
- [security] Tool “get_price” rewrote its description, which is the text the model reads
- [functional improvement] Stability: unverified → 0.03
- [cosmetic] “verify” reworded the description of “index_id”
- [cosmetic] Tool “search_indices” changed its title: Search FLOPS indices

### 2026-10-14 (score 64)

First indexed and scored.

## MCP tools (5)

### `list_indices` (~103 tokens)

List public FLOPS 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.

Input parameters:

- `family_filter` (string): Optional family prefix to filter by (e.g. 'FLOPS-H100' or 'FLOPS-B300'). Case-sensitive substring match.

### `verify` (~220 tokens)

Verify a FLOPS value

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`. Omit `value` to simply look up the current published value — then `verified` is null, which means 'not checked', NOT 'correct'. Without an API key you are checked against the public value, which is rounded to 2 decimals and delayed onto a 6-hour grid, so a full-precision real-time number will not match anonymously. No source list or source-count is exposed.

Input parameters:

- `index_id` (string, required): FLOPS index identifier (e.g. 'FLOPS-H100-OD', 'FLOPS-B300-OD').
- `value` (number): Optional. The number you want checked, e.g. 2.14. Omit it to do a plain lookup.

### `get_price` (~149 tokens)

Get a FLOPS index 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 MED), never a numeric weight. Carries no methodology or source attribution by design — the anonymous surface does not enumerate the tiers or families it withholds.

Input parameters:

- `slug` (string, required): FLOPS index slug. Accepts FLOPS-<MODEL>-OD, FLOPS-<MODEL>-SPOT, FLOPS-<MODEL>-DEPIN, or a bare gpu_model.

### `search_indices` (~94 tokens)

Search FLOPS 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.

Input parameters:

- `limit` (integer)
- `q` (string, required): Free-text query (e.g. 'h100 spot' or 'b200 on-demand').

### `get_index` (~105 tokens)

Get a FLOPS index citation

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.

Input parameters:

- `index_id` (string, required): FLOPS index id / slug, e.g. 'FLOPS-H100-OD', 'FLOPS-A100-SPOT'.

## Common questions

### What is the FLOPS Index MCP server?

FLOPS Index is an MCP server listed in the public MCP registry as io.github.zeroatflops/flopsindex-mcp. GPU rental reference prices (spot, on-demand, DePIN), key-free; every value carries a verify URL. This page covers its hosted endpoint (https://app.flopsindex.com/mcp).

### Is the FLOPS Index MCP server safe to use?

FLOPS Index scores 73 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the FLOPS Index MCP server expose?

FLOPS Index exposes 5 tools: list_indices, verify, get_price, search_indices, get_index. Their descriptions and schemas cost roughly 671 tokens of context every time the server is loaded.

### Does the FLOPS Index MCP server require authentication?

No. We connected to FLOPS Index without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the FLOPS Index MCP server still maintained?

FLOPS Index is still listed as active in the MCP registry. We last reached this channel on 18 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
