## 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 2026-11-06.

- **Endpoint Security**: 46/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 7 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement.
  - 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**: 80/100
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 530 tokens (~75/item across 7 items; 7 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 83/100
  - Stability observed for 25 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% 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 7 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 8 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.

## MCP tools (7)

### `get_current_gas` (~58 tokens)

Get the current Ethereum mainnet gas price (low / average / high, in Gwei) plus the live ETH/USD price and a send-now-vs-wait recommendation. Use this to answer "what is the gas fee right now".

### `get_l2_gas` (~69 tokens)

Compare live Layer-2 gas fees across Arbitrum, Base, Optimism, and Polygon (Gwei and the estimated wallet fee in USD for a standard transfer), and identify the cheapest right now. Use for "cheapest L2" / "L2 gas fees" questions.

### `get_eth_price` (~23 tokens)

Get the current ETH/USD spot price and its 24-hour change.

### `best_time_to_transact` (~40 tokens)

Find out whether to send a transaction now or wait — returns the current recommendation, expected savings, and when the next cheaper gas window is predicted.

### `estimate_transaction_cost` (~120 tokens)

Estimate the current USD gas cost of a specific Ethereum mainnet action (ETH transfer, ERC-20/USDC transfer, Uniswap swap, or NFT mint), or a custom gas-units amount, at the chosen priority tier.

Input parameters:

- `action` (string, required): The transaction type. Use "custom" with gas_units for anything else.
- `gas_units` (number): Required when action is "custom": the gas units the transaction uses.
- `tier` (string): Priority tier: low (cheapest), average, or high (fastest).

### `get_gas_forecast` (~76 tokens)

Get the forward-looking hourly Ethereum gas forecast (up to 24 hours ahead) with the predicted cheapest window. Use for "when will gas be cheaper", "should I wait until tomorrow", or planning a transaction.

Input parameters:

- `hours` (integer): How many hours ahead to return (1-24). Defaults to 12.

### `get_gas_history` (~72 tokens)

Get recent historical Ethereum mainnet gas prices over a chosen window, with min/max/average. Use to answer "what has gas been doing", "was gas cheaper yesterday", or to compare the current price against a recent baseline.

Input parameters:

- `range` (string): Look-back window. Defaults to 1d.

## Common questions

### What is the Gas Fee Predictor MCP server?

Gas Fee Predictor is an MCP server listed in the public MCP registry as io.github.higherbeing/gasfeepredictor-mcp. Live Ethereum and L2 gas fees: current gas, cheapest L2, forecast, ETH price, cost estimates. This page covers its hosted endpoint (https://api.gasfeepredictor.com/api/mcp).

### Is the Gas Fee Predictor MCP server safe to use?

Gas Fee Predictor 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 Gas Fee Predictor MCP server expose?

Gas Fee Predictor exposes 7 tools: get_current_gas, get_l2_gas, get_eth_price, best_time_to_transact, estimate_transaction_cost, and 2 more. Their descriptions and schemas cost roughly 458 tokens of context every time the server is loaded.

### Does the Gas Fee Predictor MCP server require authentication?

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

### Is the Gas Fee Predictor MCP server still maintained?

Gas Fee Predictor is still listed as active in the MCP registry. We last reached this channel on 6 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 Gas Fee Predictor MCP server?

VerifyMCP ran 11 checks on Gas Fee Predictor, covering TLS certificate, HSTS header, DNSSEC, Transport and 7 more. 2 items could not be completed, a gap on our side rather than a finding about Gas Fee Predictor: Authorization and HTTPS. 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.
