Loomal Index vs Glama payment infrastructure vs index.
Glama is a large, well-built directory of MCP servers for humans to browse. Loomal Index is a smaller, machine-queryable index where every listing can take payment. They solve different problems — and most builders should use both. Here's the honest comparison.
If you're choosing where to list an MCP server, the honest framing isn't 'which is better' — it's 'which job are you hiring it for.' Glama and Loomal Index are built for different consumers, and the right answer is usually both.
Glama optimizes for human discovery at scale. Loomal Index optimizes for agents that need to find, evaluate, and pay for a tool without a person in the loop. This page lays out what each does well and exactly where they differ.
What Glama does well
Glama indexes 18,000+ MCP servers and presents them for people to browse, search, and evaluate. If your goal is maximum human reach and a presence in the largest catalog, that's real, concrete value. It's a directory, and a good one — the place a developer goes to discover what MCP servers exist.
For top-of-funnel awareness among human builders, a Glama listing is worth having.
What Loomal Index adds
Loomal Index is machine-readable and payment-ready. Every server listed has the SDK integrated and is x402-ready, so an agent can query the index, get a price and a payment endpoint, and call the tool — paying per call in USDC on Base — in one transaction. Glama can't answer 'what does this cost and how do I pay for it,' because there's no price field and no payment layer in the listing. Loomal answers both, programmatically.
The difference shows up the moment an autonomous agent (rather than a human) is doing the discovering. The agent can't transact against a Glama listing; it can transact against a Loomal listing immediately.
Side by side
Audience: Glama is built for humans browsing; Loomal Index is built for agents querying. Catalog: Glama is far larger (18,000+); Loomal is smaller but every entry is payment-ready. Payment: Glama has none; Loomal has x402 on every listing, priced per call from $0.01. Discovery mode: Glama is browse-and-click; Loomal is query-and-call. SDK: Glama requires nothing to list; Loomal requires the SDK, which is precisely what makes every listing payable. Path to revenue: a Glama listing earns you nothing directly; a Loomal listing earns per call.
Read that table and the takeaway is clear — these aren't substitutes, they're different layers of the stack.
The advantage is structural
It's tempting to assume Glama could just add payments and close the gap. It can't easily: payment infrastructure on every listing requires mandating SDK integration for every server, which is a business-model change, not a feature toggle. A browse directory's whole value proposition is that listing is frictionless and requires nothing — adding a hard SDK requirement would break that.
So the catalog gap (Loomal has fewer servers) closes over time as more builders list; the payment gap (Glama has none) doesn't close for a directory without becoming a different kind of product.
Use both
List on Glama for human discovery and awareness. List on Loomal Index when you want agents to find you and pay automatically — with per-call pricing you set and reprice in one field. They're complementary: reach on one, monetization on the other, and no reason to choose.
FAQ
Is Loomal Index a Glama competitor?
Only partially. Glama is a human directory; Loomal Index is an agent-queryable, payment-ready index. They overlap on 'listing your server' but diverge on what listing gets you — reach versus the ability to charge per call.
Does Loomal Index have as many servers as Glama?
No — Glama's catalog is larger. The Loomal advantage isn't catalog size; it's that every listing is x402-ready and can earn. For agent transactions, callable-and-payable beats a longer list of links.
Can Glama just add payments to catch up?
Not easily. Payment on every listing requires mandating SDK integration, which is a business-model change for a frictionless browse directory — not a feature it can bolt on without becoming a different product.
Do I have to choose one?
No, and most builders shouldn't. List on Glama for human reach and on Loomal Index for agent discovery and monetization.
What does it cost to list on Loomal Index?
Listing has no monthly platform fee. You set a per-call price from $0.01 and Loomal takes a per-call fee on paid calls; you keep the rest.
