MCP Directories Compared: Where to Find Agent-Ready Tools in 2026
Short answer: an MCP directory is a searchable, human-browsable catalog of MCP servers, the connectors that let AI agents use real tools. A registry is the machine-readable database underneath; a directory is the layer on top that adds search, categories, and some judgment about what deserves your attention. In 2026 there are more than a dozen directories worth knowing, and they differ far more than their homepages suggest.
This is a factual comparison of the major ones: PulseMCP, Glama, Smithery, mcp.so, the official MCP registry, and our own directory at Tulimoa. Counts and details are as of late July 2026, when we checked each one.
What an MCP directory actually does
MCP, the Model Context Protocol, is an open standard for connecting AI agents to tools. Every [MCP server](/blog/what-is-an-mcp-server) packages a set of tools an agent can call: search a workspace, file a ticket, query a database.
The catch is volume. Tens of thousands of servers exist. Most are unofficial, many are abandoned, and a few are unsafe to connect. A directory's job is to make that mass searchable and to attach the signals you need before you plug anything into an agent: who published it, whether it is official, whether it is maintained, whether it runs remotely or wants a local install.
Different directories weight those jobs very differently, which is why the comparison matters more than raw size.
MCP registry vs directory: what is the difference?
The official MCP registry at registry.modelcontextprotocol.io is the canonical, machine-readable source. It is API-first, built in the open by MCP contributors, and deliberately minimal: no categories, no ratings, no editorial layer. Its real role is upstream infrastructure. The big directories ingest it and add their own metadata on top.
So registry vs directory is not an either/or choice. If you publish a server, getting into the official registry is table stakes for distribution. If you are choosing servers to connect, a directory is where the actual choosing happens, because that is where the filters and trust signals live.
The major MCP server directories in 2026
| Directory | Scale (as of July 2026) | Model | Standout trait |
|---|---|---|---|
| PulseMCP | 22,240+ servers, updated daily | Aggregator plus news | Filter pages that work like ranked lists |
| Glama | 62,930 servers in its registry | Registry, inspector, gateway | Deepest per-server metadata |
| Smithery | Count not published | Registry pivoting to agent skills | Skills catalog alongside servers |
| mcp.so | Claims the largest collection | Community marketplace | Broad community submissions |
| Official MCP registry | Not a browsing surface | Canonical machine registry | The upstream source of truth |
| Tulimoa | Curated, hand-reviewed | SaaS directory, web and MCP | Human review, English and German |
PulseMCP
PulseMCP advertises 22,240+ servers, updated daily, and as of July 2026 it holds the top search result for "MCP server directory". Its cleverest feature is that search and filter pages behave like ranked lists: query for a popular app and you get a page with a live count of matching servers, sortable by popularity, each entry tagged official or community. Around the directory it runs a clients catalog, a small set of use-case pages, weekly news posts, and a newsletter, all maintained by a team of two.
Glama
Glama is the depth play: a registry, an inspector, and a gateway under one roof, with 62,930 servers in its registry as of July 2026. Per-server pages carry license info, a quality and maintenance rating, download counts, and stars, plus automatically generated alternatives pages. It goes further than anyone on long-tail coverage and even indexes files inside the listed repositories. Its founder also maintains the most-starred awesome-mcp-servers list on GitHub (91.5k stars as of July 2026), which funnels a lot of authority its way.
Smithery
Smithery made its name as a registry and app store for AI agents. As of July 2026 its per-server pages are still indexed, but the homepage now leads with "Turn scattered context into skills for AI", and skills pages sit alongside server pages. The pivot toward agent skills is unmistakable. If you are hunting skills rather than raw MCP servers, it is the obvious first stop; for plain server discovery it has become a less focused choice. One caveat: Smithery blocks generic crawlers (more on that below), so what we can verify comes from search results rather than the site itself.
mcp.so
mcp.so describes itself as a community-driven platform that collects and organizes third-party MCP servers, and it claims the largest collection. It offers category pages, a dedicated remote-servers page, and many language versions. It is a volume-first marketplace: broad, fast-moving, and light on curation compared with Glama's metadata or a hand-reviewed catalog.
The official MCP registry
Covered above, listed here for completeness: it is the source of truth, not a browsing destination. No search facets, no categories, no opinions. Publish to it; browse elsewhere.
The crawler problem: some directories are invisible to AI answers
Here is a detail that surprised us while researching this piece. As of late July 2026, Smithery and mcp.so return HTTP 403 to non-browser crawlers, and mcpmarket.com returned 429 on repeated fetches. Google's crawler gets through; generic bots get blocked.
That has a real consequence in 2026: AI answer engines cannot read those sites. When someone asks an assistant where to find an MCP server for a given job, the assistant can only cite sources it can fetch. Directories that block crawlers forfeit those citations, which is an odd position for products built to serve AI agents. Directories that serve clean, crawlable pages get quoted instead.
It is also a useful buyer signal. If a directory's pages are locked away from agents, its listings are too.
Where Tulimoa fits
Full disclosure: Tulimoa is our product, so read this section with that in mind.
We made the opposite bet from the aggregators. [The Tulimoa directory](/discover) is deliberately not the biggest: every listing is reviewed by a human before it goes live, typically in around 24 hours. Listings are SaaS products with an MCP status attached, not raw repos, so you see what the tool is, what it costs, where the company is based, and whether an MCP server exists for it. It is free to browse and free to be listed in, with no pay-to-rank of any kind, in English and German. We are a two-founder company building it from Germany.
It is also readable both ways: on the web and over MCP. Our server at mcp.tulimoa.com lets an agent search the directory directly, with no account needed for reads. And if you run a SaaS with (or without) an MCP server, you can [submit it for a free listing](/submit) and get a reviewed profile with a do-follow backlink.
The trade-off is honest: tens of thousands of entries is not what we offer. A catalog where a human has looked at every entry is.
How to choose
- You want the broadest sweep of everything that exists: PulseMCP or Glama.
- You want deep metadata before connecting anything (license, maintenance, quality signals): Glama.
- You are hunting agent skills, not just servers: Smithery.
- You are publishing a server and want distribution: the official registry first, then submit everywhere else.
- You want a curated, human-reviewed catalog of agent-ready SaaS, in English or German: Tulimoa.
If you want a workflow rather than a catalog choice, we wrote a practical guide on [how to find MCP servers](/blog/find-mcp-servers) for a specific job, and a [ranked list of the best MCP servers in 2026](/blog/best-mcp-servers-2026) if you would rather start from picks.
Frequently asked questions
What is the difference between an MCP registry and an MCP directory?
The registry is the machine-readable source of truth, run as open infrastructure with an API and no editorial layer. A directory is a human-facing catalog built on top: search, categories, ratings, and curation. Most directories ingest the official registry and add their own metadata.
Which MCP directory is the biggest?
By published numbers as of July 2026, Glama lists 62,930 servers in its registry and PulseMCP advertises 22,240+, while mcp.so claims the largest collection without a comparable public count. Biggest is not the same as most useful: past a few thousand entries, filtering and trust signals matter more than totals.
Are MCP directories free to use?
All the directories compared here are free to browse. Tulimoa's directory is also free to be listed in, with no listing fee and no paid ranking; other directories have their own submission processes, usually starting from the official MCP registry.
