FalsifyLab vs every finance MCP + data API for AI agents

honest comparison. different products, different prices, different buyers. here's where each one fits. updated 2026-05-22 after a full MCP-server landscape sweep.

The short version

Coverage matrix — what each one actually has

TT=Token Terminal · FDS=Financial Datasets · FMP=Financial Modeling Prep MCP · AV=AlphaVantage MCP · Kukapay=open-source MCP suite (30+ single-purpose servers)

When to pick each

Pick Token Terminal if

You're an analyst at a fund evaluating $5M+ DeFi positions. You need protocol-level financials (revenue, fees, MAU, P/E ratios) and you click through dashboards. $350/mo is rounding error for your AUM. Their Sheets/Excel plugin is the core feature.

Pick Nansen if

You want to know which wallets are the smart money and what they're doing. Wallet labeling is their wheelhouse. $49-69/mo after their recent price cut. Less useful if you're building autonomous agents — their UI is the product.

Pick Dune if

You write SQL and want to compose your own analyses across on-chain data. Free tier with 2,500 credits is generous if you cache results. Closest to a programmable platform but you're building everything from primitives. Not agent-fit out of the box.

Pick Arkham if

You're doing wallet forensics — tracking specific addresses, labeling unknown wallets, investigating flows for OSINT or compliance. $149/mo Standard. $999/mo Pro for full API. Different problem space.

Pick Quiver Quant if

Your strategy is purely US equity with insider + Congressional trade focus. $25/mo retail + $30-75/mo API. Excellent on Form 4 specifically (Insider Confidence Index). No crypto, no AI agent fit.

Pick Financial Datasets if

You're a serious equity quant who needs 30 years of clean US equity history with real-time L1 quotes. $200-2,000/mo + pay-as-you-go. REST API only, no MCP transport. US-only, no crypto, no prediction markets.

Pick Financial Modeling Prep MCP if

You want equity statements + SEC filings via MCP at the lowest price point. Basic free, paid from ~$22/mo. Doesn't ship Polymarket, DeFi-yield emissions-stripping, or HL vaults. Good companion to FL if your workflow is pure equity.

Pick EODHD MCP if

You want 77 read-only tools across stocks + fundamentals + technicals + macro under one MCP. $99/mo (All-in-One). Strong on equity history, no crypto-DeFi-onchain layer.

Pick AlphaVantage MCP if

You already pay AlphaVantage for equity/forex/crypto data and want a thin LLM wrap. Free tier + premium $50-250/mo. Doesn't ship SEC Form 4 clusters, Polymarket, on-chain, or confluence.

Pick Messari AI Toolkit MCP if

You're at an institution that already pays Messari Pro or Enterprise ($500+/mo). Excellent on crypto research depth, no equity coverage, no Polymarket, no SEC.

Pick Kukapay's open-source suite if

You're a builder who wants $0 cost and you're willing to self-host 5-8 separate MCP servers (etf-flow-mcp + whale-tracker-mcp + defi-yields-mcp + hyperliquid-info-mcp + crypto-funds-mcp + funding-rates-mcp + ...). No bundled hosting, no confluence layer, no equity side. DIY is the trade-off.

Pick FalsifyLab if

• You're building an autonomous research agent in Claude Code, Cursor, Cline, or any MCP client
• You need crypto AND equity signals in the same workflow
• You want to stack confluence across insiders, ETF flows, DeFi yields, and Polymarket whales in one call
• You want a real free tier to test with — no signup, no card, no email
• $19/mo for real-time + 100 results + 90 days history fits your budget

FAQ

Is this an investment advice service?

No. We surface public data with light enrichment (emissions stripping, signal aggregation, confluence detection). The agent does its own analysis. Backtest before acting.

Why is your Pro tier $19/mo when Token Terminal is $350/mo?

Different products, different buyers. Their data is protocol financials for VCs. Ours is tradeable alpha signals for AI agents. Their team has 30 engineers. We have one. Their data costs more to produce. Ours is curated wrappers around clean public sources.

Does the free tier really not require signup?

Yes. Free tier: 3 tools (yield, HL vaults, macro tape), 5 results/query, 60 req/hr. Auto-issues a tier-0 key bucketed by hash(IP + User-Agent). Other 10 tools are Pro $19/mo.

What's the killer feature?

confluence_today — the 9th tool. Returns tickers and assets where 2+ FalsifyLab signals align in the last 24h. Stacks insider clusters + 8-K + ETF flows (equity side) and DeFi yields + airdrops + HL vaults + Polymarket whales (crypto side). Nobody else stacks all of these in one call because nobody else has all the underlying feeds.

Can I see it working before I install?

Yes. falsifylab.com/demo runs a public agent reading our live data feeds every 15 minutes and writing a memo grounded in real numbers from the tool outputs.
