preflight_safe_swap
Discover and prepare a risk-checked Solana swap through Preflight SafeSwap. Use this when an autonomous agent needs a USDC-paired Solana swap with explicit route, risk, slippage and fee disclosure. The paid HTTP endpoint costs $0.005 USDC and embeds a disclosed 3 bp execution fee.

Preflight SafeSwap — questions

Answers built from our own checks of this server.

What can Preflight SafeSwap do?
It exposes 2 tools, read directly from the server on our last check. Among them: preflight_capabilities, preflight_safe_swap. 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 Preflight SafeSwap working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 92 checks got a reply (98.9%), average response time 759 ms. The bar chart above shows every period we have measured.
How do I connect Preflight SafeSwap?
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 Preflight SafeSwap need an API key?
No. Preflight SafeSwap completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 2 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Preflight SafeSwap?
It answers our handshake in 759 ms on average, which is faster than 16% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
