## 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 2026-11-05.

- **Endpoint Security**: 74/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Nothing on it is marked destructive, but we can't show that an anonymous caller can only read: full credit needs the server to list at least one tool and every tool to be verifiably read-only. We use a best-effort check of tool names and descriptions to tell read-only tools from tools that change things, so some genuinely read-only tools may not get full credit. Names that start with a read verb (get, list, read, search and similar) and accurate readOnlyHint annotations help. Meet that to earn full credit, or require authorisation.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - 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**: 60/100
  - AI-judged instruction clarity (fair).
  - Context-footprint check failed: tool/resource definitions use about 1520 tokens (~116/item across 13 items; 13 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 33/100
  - Stability observed for 10 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 88/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 57% of tool parameters carry a description.
  - Structured output schemas are declared (62% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 13 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 14 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

First indexed and scored.

## MCP tools (13)

### `backtest` (~207 tokens)

Crypto strategy backtest

Backtest crypto strategies on 399 Coinbase coins without survivorship bias. DIY backtests usually use today's coin list, so dead coins vanish and returns are overstated; this rebuilds the universe from each past day's top coins. Breakout, momentum, dip-buy or MA-trend rules on daily data with fees, slippage, H1/H2 split and a luck flag. No data fetching or backtest code on your side. Price: $0.05 USDC per call (x402, Base mainnet). Free pre-check: validate_backtest. Free sample: backtest_sample.

Input parameters:

- `end`: YYYY-MM-DD
- `fee` (number): Fee per side (0.009 = 0.9%)
- `include_trades` (boolean)
- `initial_capital` (number): Starting capital in USD
- `slippage` (number): Slippage per side
- `start`: YYYY-MM-DD
- `strategy` (required)
- `universe`

### `market_signals` (~115 tokens)

Daily crypto market signals

Daily crypto market regime in one call: BTC/ETH vs 20/50-day MAs, breadth of the point-in-time top-N (no survivorship bias), coins nearest a 20-day breakout, and the R1 breakout strategy's gate and entry signals. No candle fetching or indicator code. Completed UTC daily closes only. Price: $0.01 USDC per call (x402, Base mainnet). Free sample: signals_sample.

Input parameters:

- `top_n` (integer): Universe size for breadth / breakout scan

### `token_check` (~133 tokens)

Token scam / honeypot risk check

Token scam check in one call instead of wiring up five data sources: honeypot sell simulation, unverified code, mint/pause/blacklist powers, taxes, upgradeable proxy, age, liquidity, fake major-token (e.g. fake USDC) lookalikes and spam-airdrop patterns. Base, Ethereum or Solana. Never visits metadata URLs. Price: $0.02 USDC per call (x402, Base mainnet). Free pre-check: validate_token_check.

Input parameters:

- `address` (string, required): Token contract / mint address
- `chain` (string, required): base, ethereum or solana

### `optimize_strategy` (~196 tokens)

Robust strategy parameter optimiser

Find robust strategy params, not lucky ones: tests up to 50 combos on the same survivorship-bias-free backtester, ranks by worst-half (H1/H2) return with neighbourhood smoothing, flags overfitting, and recommends the most stable parameters rather than the best-fit ones. Price: $0.50 USDC per call (x402, Base mainnet). Free pre-check: validate_optimize.

Input parameters:

- `end`: YYYY-MM-DD
- `fee` (number): Fee per side (0.009 = 0.9%)
- `grid` (object, required): param -> values to try; <= 50 combos total, <= 10 values per param
- `initial_capital` (number): Starting capital in USD
- `rank_by` (string)
- `slippage` (number): Slippage per side
- `start`: YYYY-MM-DD
- `strategy` (required)
- `universe`

### `universe_snapshot` (~121 tokens)

Point-in-time top-N coin universe

Survivorship-free top-N coin list for any past date: Coinbase USD pairs ranked by trailing 20-day dollar volume using only data available that day. Fixes your own backtests: picking today's top coins hides the ones that died and overstates returns. Price: $0.05 USDC per call (x402, Base mainnet). Free pre-check: validate_universe.

Input parameters:

- `date`: YYYY-MM-DD
- `min_age_days` (integer)
- `min_avg_dollar_volume` (number)
- `top_n` (integer)

### `signals_sample` (~63 tokens)

Market signals, delayed free sample

Free, one day delayed: yesterday's full /signals result (BTC/ETH trend, breadth, breakout watchlist, R1 gate) so you can judge quality before paying. Today's result: paid market_signals ($0.01). Limit 60/hour per client.

### `backtest_sample` (~98 tokens)

Crypto backtest, free sample

Free sample of the paid `backtest` tool on the same survivorship-bias-free engine: any strategy, point-in-time top-10 universe, window = last `days` (14..90) completed days, summary only. Full version: backtest ($0.05). Limit 30/hour per client.

Input parameters:

- `days` (integer): Window length in days, ending on the last completed UTC day
- `strategy` (required)

### `health` (~19 tokens)

Service status (free)

Free: service status, prices, network and data range.

- `initial_capital` (number): Starting capital in USD
- `slippage` (number): Slippage per side
- `start`: YYYY-MM-DD
- `strategy` (required)

Input parameters:

- `address` (string, required)
- `chain` (string, required)

### `validate_universe` (~62 tokens)

Validate a universe request (free)

Free: check universe_snapshot arguments (date in range, enough history) before paying.

## Common questions

### What is the Grok Crypto Quant API MCP server?

Grok Crypto Quant API is an MCP server listed in the public MCP registry as dev.fly.grok-backtest-api/crypto-quant. Bias-free crypto backtests (399 coins), signals, token scam checks. Free samples; pay via x402 USDC. This page covers its hosted endpoint (https://grok-backtest-api.fly.dev/mcp).

### Is the Grok Crypto Quant API MCP server safe to use?

Grok Crypto Quant API scores 72 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 Grok Crypto Quant API MCP server expose?

Grok Crypto Quant API exposes 13 tools: backtest, market_signals, token_check, optimize_strategy, universe_snapshot, and 8 more. Their descriptions and schemas cost roughly 1,297 tokens of context every time the server is loaded.

### Does the Grok Crypto Quant API MCP server require authentication?

No. We connected to Grok Crypto Quant API without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the Grok Crypto Quant API MCP server still maintained?

Grok Crypto Quant API is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What did VerifyMCP test on the Grok Crypto Quant API MCP server?

VerifyMCP ran 13 checks on Grok Crypto Quant API, covering TLS certificate, Authorization, HTTPS, HSTS header and 9 more. Supply Chain Security and Provenance & Transparency do not apply to a hosted endpoint, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
