# Tool Highlight: Smithery — the MCP Registry That Also Hosts and Routes Your Server

> The official registry tells an agent which MCP servers exist. Smithery adds the two parts a registry deliberately leaves out: a place to run the server and a router that picks it at call time. Here's what it does, who it's for, and where the free line sits.

## Key takeaways

- A registry and a host are different jobs. The official MCP registry (registry.modelcontextprotocol.io) is a machine-readable feed of server.json records that tells a client which servers exist and where to find them — it does not run anything. Smithery pairs a discovery registry with two things the official feed omits on purpose: hosted remote endpoints and a runtime router (Toolbox).
- You deploy by dropping a `smithery.yaml` at your repo root with `runtime: "typescript"`; Smithery reads it, runs `npm ci`, builds, containerizes your server as an HTTP service at `https://server.smithery.ai/<your-server>`, and handles load balancing, scaling, and monitoring — the stateless-MCP deploy work you'd otherwise do yourself. Set `target: "local"` instead and it registers a CLI-installable server for discovery without hosting it.
- Self-reported scale: Smithery grew from ~10 servers at launch to 6,000+ listed and hosted, serving tens of thousands of tool calls a day. Pricing is Free / Pro $20 per month / Enterprise custom.
- The honest caveat: hosting on Smithery means your server's uptime, auth surface, and analytics run on someone else's control plane. That's the right trade for shipping a remote MCP server this quarter; it's the wrong one if the server is your product's core moat and you need to own the deploy.

## At a glance

| Option | What it gives you | Runs your server? | Best for |
| --- | --- | --- | --- |
| Official MCP registry (preview) | Machine-readable server.json feed clients read to discover servers; name ownership | No | Being discoverable by every MCP client, everywhere, at zero cost |
| Smithery — hosted | Registry listing + a remote HTTPS endpoint (server.smithery.ai) with load balancing, scaling, monitoring, and a runtime router | Yes, on Smithery infra | Shipping a remote MCP server fast without building a deploy pipeline |
| Smithery — local (target: local) | Registry entry for a CLI-installable server clients discover and run on their own machine | No (client runs it) | Distributing a server users run locally, still discoverable through Smithery |
| Glama / PulseMCP | Human-browsable discovery directories that crawl the ecosystem and let you claim a listing | No | Extra visibility and curation beyond the official feed |
| Roll your own host | Full control of uptime, auth, analytics, and scaling | Yes, on your infra | A server that is a core product surface or has strict control-plane requirements |

**What it is:** Smithery is a [Model Context Protocol](/posts/the-official-mcp-registry-explained.html) platform that does three jobs at once — it is a searchable **registry** of [MCP servers](/topics/mcp), a **host** that runs your server as a remote HTTPS endpoint, and a runtime **router** (Toolbox) that picks the right server for a given call. You can browse and install servers through its CLI, or publish and host your own.
> **The 10-second answer:** The official MCP registry tells a client *which servers exist*. Smithery adds the two parts a registry leaves out on purpose: a place to *run* the server and a router to *reach* it. If you want your MCP server discoverable and hosted without building a deploy pipeline, that's the pitch. Self-reported, it lists and hosts **6,000+ servers** and serves **tens of thousands of tool calls a day**. Free tier; Pro is **$20/month**.

Why a registry isn't a host — and why that matters
The thing founders miss when they first list an MCP server is that [a registry is a feed, not a runtime](/posts/agent-registry-vs-mcp-registry-discovery.html). The **official registry** at `registry.modelcontextprotocol.io` — backed by Anthropic, GitHub, Microsoft, and PulseMCP, and still in **preview** rather than GA — publishes a machine-readable `server.json` record for each server under a name you prove you own. A client reads that feed to *discover* your server. Then it's on you to actually run the thing somewhere a client can reach it.
Smithery is a downstream layer that closes that gap. The registry says the server exists; **Smithery's endpoint runs it**; **Toolbox** selects it at call time. That's the one non-obvious idea here: discovery, hosting, and routing are three separate jobs, and most teams only budget for the first one.
Deploying: one file at the repo root
The hosted path is deliberately short. You drop a **`smithery.yaml`** at your repository root. For a TypeScript server you set:
```
runtime: "typescript"
```
You don't hand-write a config schema — Smithery **auto-detects it from your TypeScript exports**. On a hosted deploy, Smithery parses the file, runs `npm ci`, builds via your `package.json` module entry, packages the server into a **containerized HTTP service**, and serves it at `https://server.smithery.ai/your-server` with load balancing, scaling, and monitoring handled for you. That's the same [stateless-MCP deploy work](/posts/mcp-stateless-load-balancer-deploy-guide.html) you'd otherwise wire up behind your own load balancer.
Prefer to ship a server users run themselves? Set `target: "local"` and Smithery registers a **CLI-installable** server for discovery without hosting it — the client runs it on their machine, Smithery just makes it findable. Either way, [test it with MCP Inspector](/posts/how-to-test-an-mcp-server.html) before you publish (`npx @modelcontextprotocol/inspector dist/index.js`).
Who it's for
- **Founders shipping a remote MCP server this quarter** who don't want to own a deploy pipeline. Hosted Smithery is the shortest path from "the server works locally" to "a client can reach it over HTTPS."
- **Anyone distributing a local-first server** who still wants registry discovery — `target: "local"` gets you listed without renting compute.
- **Teams treating [the MCP server as a distribution channel](/posts/mcp-server-is-a-distribution-channel-not-a-feature.html)**, where being *found* by agents is the point and hosting is a detail to outsource.

Where the free line sits — and the honest caveat
Pricing is **Free / Pro $20 per month / Enterprise custom**. The free tier is enough to list a server and try hosted endpoints; paid tiers raise usage limits and add features. (Some older write-ups cite a $10 entry tier — check the live pricing page before you budget.)
The caveat is the same one that applies to any managed control plane: **hosting on Smithery means your server's uptime, auth surface, and analytics run on infrastructure you don't own.** For an integration that's a means to an end, that's a good trade — you're buying back the deploy pipeline. For a server that *is* your product's moat, or one with strict data-residency or [auth requirements](/posts/tool-highlight-workos-mcp-server-auth-authkit.html), owning the deploy is worth the extra work. The stateless spec cuts both ways: it's what lets Smithery scale your server, and it's what lets you [scale it yourself](/posts/ship-stateless-mcp-server-stable-sdk-today.html) when the time comes.

## FAQ

### What is Smithery?

Smithery is a Model Context Protocol (MCP) platform that combines three jobs: a searchable registry of MCP servers, hosting that runs your server as a remote HTTP endpoint on Smithery's infrastructure, and a runtime router (Toolbox) that selects the right server for a call. You can discover and install servers locally through its CLI, or publish and host your own. Self-reported, it lists and hosts 6,000+ MCP servers and serves tens of thousands of tool calls a day.

### How is Smithery different from the official MCP registry?

The official registry at registry.modelcontextprotocol.io — backed by Anthropic, GitHub, Microsoft, and PulseMCP, and still in preview rather than GA — is a machine-readable metadata feed: it publishes server.json records so clients can discover which servers exist, under a name you prove you own. It does not run your server. Smithery is a downstream directory that adds hosting and routing on top: the registry says a server exists, Smithery's endpoint runs it, and Toolbox picks it at call time. Use the official registry to be discoverable everywhere; use Smithery when you also want it hosted.

### How do I deploy an MCP server to Smithery?

Put a `smithery.yaml` at your repository root. For a TypeScript server, set `runtime: "typescript"` — the config schema is auto-detected from your TypeScript exports, so you don't hand-write it. On a hosted deploy, Smithery parses the file, installs with `npm ci`, builds via your package.json module entry, packages the server into a containerized HTTP service, and serves it at https://server.smithery.ai/your-server with load balancing and monitoring handled for you. Set `target: "local"` to register a CLI-installable local server for discovery instead of hosting it.

### What does Smithery cost?

Pricing is a Free tier, Pro at $20 per month, and custom Enterprise. The free tier is enough to list a server and try hosted endpoints; paid tiers raise usage limits and add features. Some older sources cite a $10 entry tier — check the live pricing page before you budget.

### Should I host on Smithery or run my own MCP server?

Host on Smithery when the server is a means to an end — an integration you want discoverable and reachable without owning a deploy pipeline. Run your own (or use a stateless MCP server behind your own load balancer) when the server is a core product surface, when auth and data residency have to stay in your control plane, or when you need custom scaling behavior. The same stateless spec that makes MCP servers easy for Smithery to scale also makes them easy for you to scale yourself.
