How do I monetize my MCP server?

Publish it on the FiatDock marketplace and set a per-call price. AI agents that call your service pay that price in USDC over x402, settled on-chain directly to your payout wallet. You keep 100% for your first 30 days (the launch offer), then FiatDock takes a 1% platform fee as an on-chain split. Listing is free; there are no subscriptions to sell.

How and when do I get paid?

Per call, on-chain, immediately. When an agent calls your paid service through the gateway, the buyer's payment settles directly to your payout wallet before the call is forwarded to your MCP server. FiatDock is non-custodial — it never holds, routes or forwards your funds; your 99% (or 100% during the first-month launch offer) lands in your wallet directly.

Do I need to be verified to sell?

No. Anyone can list an MCP service without verification — it goes live and is discoverable immediately. The Verified badge ($20/month + a one-time identity check via a licensed provider, plus a security scan) is optional; it adds a trust mark and ranks your listing higher, but it is not required to publish or get paid.

Will my MCP endpoint be exposed?

No. For paid listings the buyer's agent calls a gateway URL (/s/your-id); your raw MCP endpoint stays private. The gateway forwards each call signed with an HMAC (X-FiatDock-Gateway) so you can accept only gateway traffic.

Q: Can I list a stdio/npx MCP server without hosting it?

Yes. Free catalog listings can point at an npm package name instead of a hosted URL — agents run your server locally via npx. Roughly 75% of MCP servers are stdio-only (PulseMCP tracks 20,274 servers and only about 24% are remote-available), so most servers can be listed as-is. Paid per-call listings still require a hosted Streamable-HTTP HTTPS endpoint, because the payment gateway forwards paid calls to it.

List in four steps

Create an account

Publish your service

At /sell/new: name, your npm package name (stdio/npx) or MCP endpoint URL, summary, category, price per call (or 0 for free — paid listings need a hosted HTTPS endpoint). Live + discoverable immediately.

Set a payout wallet

Add the EVM address that receives your share — settled on-chain directly to you, per call.

(Optional) Get Verified

Pay the $20/mo badge + a one-time identity check for a trust mark + ranking boost.

How you get paid

Every paid call is a direct, on-chain payment from the buyer's wallet to your wallet via x402 on Base — FiatDock takes its 1% as an atomic on-chain split, never by receiving and forwarding your money. So you're paid per call, immediately, non-custodially. Your raw MCP endpoint stays private behind the gateway URL /s/{id}; it accepts only gateway-signed traffic (X-FiatDock-Gateway HMAC).

Pricing for sellers

Free to list. No listing fee, no subscription to sell.
0% for your first 30 days, then a 1% platform fee per paid call (taken as an on-chain split). During the launch window the buyer pays the full price in one payment straight to you. See pricing.
Optional $20/month Verified badge — identity-checked + security-scanned; ranks higher. Not required to sell.

Is there any demand?

Verifiable numbers, not promises: 25,000+ MCP tool calls hit FiatDock's /mcp endpoint last month, from 2,000+ unique MCP clients, and 500+ people browse the catalog monthly. Across the wider x402 ecosystem, $1.11M settled over 3.69M transactions in the last 30 days (x402scan); top data-API sellers there earn roughly $1–3K/month.

And where the money goes matters: listing directories (Smithery, Glama, mcp.so, PulseMCP) pay you $0 for a listing, and hosted marketplaces (Apify, MCPize) take a 15–20% cut, hold the funds and pay out on a schedule. FiatDock takes 0% your first month, then 1% — paid on-chain, directly to your wallet.

Frequently asked

Do I need verification to sell?

No — anyone can publish without verification; your listing is live and discoverable right away. Verification (the $20/mo badge) is an optional trust mark.

When do I get paid?

Per call, on-chain, immediately — the buyer's payment settles to your wallet before each call is forwarded to your server.

Is it custodial?

No. Funds move buyer→seller directly via x402; FiatDock holds nothing and takes its 1% as an on-chain split.

Can I list a stdio/npx MCP server without hosting it?

Yes — a free listing can be just your npm package name (agents run it via npx). ~75% of MCP servers are stdio-only, so most can be listed as-is. Paid per-call listings still need a hosted Streamable-HTTP HTTPS endpoint.
