Available tools 1

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

crypto
crypto_estimate_gas
Use this when you need to compare gas prices across multiple EVM chains at once. Returns multi-chain gas estimates in JSON. 1. chains: array of chain gas data with chain name 2. low: gas price in gwei for slow confirmation 3. medium: gas price in gwei for standard confirmation 4. high: gas price in gwei for fast confirmation 5. transferCostUsd: estimated USD cost for a simple transfer on each chain 6. cheapestChain: which chain currently has the lowest gas cost Example output: {"chains":[{"chain":"base","low":0.005,"medium":0.008,"high":0.012,"transferCostUsd":0.01},{"chain":"ethereum","low":12.5,"medium":18.0,"high":25.0,"transferCostUsd":0.85}],"cheapestChain":"base"} Use this FOR choosing the cheapest chain before a cross-chain transaction. Essential for multi-chain agents that need to optimize gas costs. Do NOT use for single-chain gas only -- use gas_get_current_price instead. Do NOT use for swap quotes -- use dex_get_swap_quote instead. Do NOT use for bridging -- use bridge_find_best_route instead.

Gas Estimator API — questions

Answers built from our own checks of this server.

What can Gas Estimator API do?
It exposes 1 tools, read directly from the server on our last check. Among them: crypto_estimate_gas. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Gas Estimator API working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 32 ms. The bar chart above shows every period we have measured.
How do I connect Gas Estimator API?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Gas Estimator API need an API key?
No. Gas Estimator API completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 1 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Gas Estimator API?
It answers our handshake in 32 ms on average, which is faster than 99% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is Gas Estimator API open source?
Yes — it is published under the MIT licence, written in TypeScript and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
