bridge
bridge_find_best_route
Use this when you need to bridge tokens between different blockchains. Returns ranked bridge routes with fees and timing in JSON. POST variant of bridge_find_best_route -- same params passed as JSON body instead of query string. 1. routes: array of bridge options ranked by best value 2. bridgeProvider: which bridge protocol (Stargate, Across, Hop, Connext, etc.) 3. estimatedTime: expected bridge completion time in seconds 4. fee: total bridging fee in USD 5. amountReceived: expected output amount on destination chain 6. steps: detailed step-by-step route (approve, bridge, swap if needed) Example output: {"routes":[{"bridgeProvider":"Stargate","estimatedTime":60,"fee":0.85,"amountReceived":"999.15","steps":["approve USDC","bridge via Stargate"]}],"fromChain":"Ethereum","toChain":"Base","token":"USDC"} Use this BEFORE moving assets cross-chain to find the cheapest and fastest bridge. Essential for multi-chain portfolio management. Do NOT use for same-chain swaps -- use dex_get_swap_quote instead. Do NOT use for gas prices -- use gas_get_current_price instead. Do NOT use for multi-chain gas comparison -- use crypto_estimate_gas instead.

Cross-Chain Bridge Route API — questions

Answers built from our own checks of this server.

What can Cross-Chain Bridge Route API do?
It exposes 1 tools, read directly from the server on our last check. Among them: bridge_find_best_route. 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 Cross-Chain Bridge Route API working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 91 checks got a reply (0.0%), average response time 50 ms. The bar chart above shows every period we have measured.
The registry lists Cross-Chain Bridge Route API as active — why does it not respond?
The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.
How do I connect Cross-Chain Bridge Route API?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Cross-Chain Bridge Route API need an API key?
No. Cross-Chain Bridge Route 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.
Is Cross-Chain Bridge Route API open source?
The code is open source: it is published under the MIT licence, written in TypeScript and 0 stars on GitHub. The licence covers the code in the repository, not the hosted service at bridge-routes.api.klymax402.com, which runs on its operator's own terms.
