PreFlyte — DeFi Financial Intelligence for AI Agents is an MCP server with 9 tools an agent can call, among them assess_opportunity, check_entry_viability, check_pool_viability. It answers at https://mcp.preflyte.xyz/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 12 September 2026; the last check, on 24 October 2026, succeeded.
Evidence-based market data for AI agents deploying capital in DeFi. Empirical, not advertised.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
assess_opportunity | Assess the best DeFi opportunity for a given capital amount and strategy. This is the "cold start" tool — call it first to understand where your capital is viable before making any moves. One call gives you chain viability, ranked opportuni Inputs: api_key, asset, action, position_size_usd, strategy, chain |
check_entry_viability | Before entering a lending position, verify that the market is actually open and has capacity. Checks market status (active, frozen, borrowing enabled), supply/borrow caps, and available liquidity. Returns a clear viable/not-viable verdict. Inputs: api_key, protocol, chain, asset, action, amount_usd |
check_pool_viability | Before swapping on Uniswap V3, check if pools have sufficient liquidity for the intended trade size. Finds all matching pools for a token pair, assesses trade impact relative to pool TVL, and recommends the best pool. Args: api_key: Your Pr Inputs: api_key, chain, token_pair, trade_size_usd |
estimate_net_position | Detailed financial estimate for a specific lending position — what will I actually earn (or pay) after gas costs? Combines current live rates, gas costs, and historical computed returns to project net yield over a holding period. Args: api_ Inputs: api_key, protocol, chain, asset, action, position_size_usd |
gas_timing | Tell agents whether now is a good or bad time to transact, based on historical gas patterns. Compares current gas to 24-hour and 7-day averages, identifies the cheapest hours of the day, and estimates reference transaction costs. Args: api_ Inputs: api_key, chain |
get_market_snapshot | Get current market snapshot for a specific lending market. Returns the latest rates, risk parameters, token price, and gas price. This is the foundation of RealityCheck — giving agents ground truth about current market conditions before the Inputs: api_key, protocol, chain, asset |
get_ranking | Get ranked list of best DeFi lending returns, sorted by net APY. Args: api_key: Your PreFlyte API key (required). window_days: Return window — 7, 14, 30, or 90 days. Default 7. strategy: "supply" or "borrow". Default "supply". top_n: Number Inputs: api_key, window_days, strategy, top_n |
get_returns | Query historical DeFi lending returns from the ProfitLens engine. Returns real, empirically measured after-fee returns — not theoretical APY projections. Data is computed from on-chain index ratios every 30 min. Args: api_key: Your PreFlyte Inputs: api_key, chain, protocol, asset, strategy, window_days |
verify_claim | Verify factual claims about current DeFi market conditions. Supports two modes: - Single claim: provide claim_type, value, operator (and protocol/chain/asset as needed). Returns one verification result. - Batch mode: provide a JSON-encoded Inputs: api_key, claim_type, value, operator, protocol, chain |

It answered our last check on 24 October 2026 in 234 ms. Over 6 checks since 12 September 2026 it answered 6. Status here comes from Neuronto's own probes, not from the publisher.
Yes. It is published by preflyte.xyz and served from mcp.preflyte.xyz, the vendor's own domain: https://mcp.preflyte.xyz/mcp.

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://mcp.preflyte.xyz/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
Publisher: xyz.preflyte. Endpoint host: mcp.preflyte.xyz. ARD identifier: urn:air:xyz.preflyte:mcp:preflyte.
First indexed 10 September 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
