MCP servers for SEO and GEOPart 3 of 6

How to publish to the official MCP Registry

The official MCP Registry is the public catalog of MCP servers at registry.modelcontextprotocol.io, and you publish to it with one server.json file and the mcp-publisher tool. It has no listing pages of its own, but directories such as Glama and mcprush copy it, so one entry becomes several listings.

What is the MCP Registry?

It is an API, run by the MCP project, that stores each server's name, title, description, version, website and how to connect. Clients, directories and quality checkers query it as the source of truth for which servers exist; people rarely browse it.

It's also the most searched term in this series, with about 1,300 searches a month for "mcp registry" and 170 for "official mcp registry".

Does the MCP Registry help SEO and GEO?

Yes, through the directories that copy it. After we published, Glama listed our server without a submission and mcprush listed it beside our npm packages, which gave us pages on other domains. And modelcontextprotocol.io itself is cited in AI answers more than most MCP directories.

The registry has no pages, so it gives no backlink. The title, description and websiteUrl you publish travel into every copy, so write them for a buyer. Our MCP marketplaces comparison shows which of those directories link back.

How do I publish an MCP server to the registry?

Install mcp-publisher, write a server.json, prove you own the namespace and run mcp-publisher publish. This is the file we published for our hosted server:

{
  "$schema": "https://static.modelcontextprotocol.io/schemas/2025-12-11/server.schema.json",
  "name": "ai.workpods/agent-ready-mcp",
  "title": "Agent Ready Website Audit",
  "description": "SEO and AI search audit for any website: technical SEO, schema, AI crawler access and llms.txt.",
  "version": "1.0.1",
  "websiteUrl": "https://workpods.ai/tools/agent-ready",
  "remotes": [
    { "type": "streamable-http", "url": "https://mcp.workpods.ai/mcp" }
  ]
}

A domain-style name such as ai.workpods/... needs a DNS TXT record on your domain. A name such as io.github.<user>/... needs a GitHub login instead.

brew install mcp-publisher        # or download a release binary

# DNS proof: add the TXT record mcp-publisher prints, v=MCPv1; k=ed25519; p=<public key>
openssl genpkey -algorithm Ed25519 -out key.pem
mcp-publisher login dns --domain workpods.ai --private-key <hex-private-key>

mcp-publisher publish
curl -s "https://registry.modelcontextprotocol.io/v0/servers?search=workpods" | head -c 600

Keep the private key out of every repository. To update the entry, raise version and publish again. You can see our live entry with the same query.

How do I publish an npm package to the registry?

Use packages in place of remotes, and first publish an npm version whose package.json declares the server name in an mcpName field. The registry checks that field to confirm the package belongs to you.

{
  "name": "@workpods/agent-ready",
  "version": "0.1.1",
  "mcpName": "ai.workpods/agent-ready",
  "homepage": "https://workpods.ai/tools/agent-ready"
}

Our npm packages lacked mcpName at first, so we had to ship new versions before the registry accepted them.

What makes a good registry entry?

A good entry is short, specific and the same everywhere you publish. Every field is copied into other directories, so write each one for a stranger reading a listing page.

FieldWhat to write
nameYour namespace and a slug you won't need to change
titleThe product name buyers know, without "MCP server" added
descriptionThe job in buyer words, under 100 characters
websiteUrlA product page that explains the server, not the home page

Use your own domain as the namespace if you can. ai.workpods/agent-ready-mcp reads as official and doesn't depend on one person's GitHub account. A rename doesn't reach the registry on its own, so keep one name across the registry, the server handshake and every directory.

What should be ready before you publish?

Your server's own metadata. Directories and checkers also connect to the server itself and read its handshake: name, title, description, website and icon.

Our score on Manufact's leaderboard rose from 68 to 83, with a followed link to our site, once we added those fields; our MCP server metadata guide has the code. If you haven't yet, submit to the assistant directories too, starting with Claude's connector directory. Every channel is ranked in our MCP directory guide.

To check whether agents can find your server and read your site, run Agent Ready. Registry publishing is also part of our agent platform work.

Questions

Questions buyers ask

What is an MCP registry?

A catalog of MCP servers that clients and directories query for each server's name, description, version and connection details. The official one is run by the MCP project at registry.modelcontextprotocol.io.

Is the official MCP Registry free?

Yes. Publishing costs nothing; you need the mcp-publisher tool and proof that you own the namespace, through a DNS TXT record or a GitHub login.

Do I need a remote server for the MCP Registry?

No. The registry accepts remote servers and packages such as npm. An npm package must declare the server name in an mcpName field in its package.json.

Does the MCP Registry give a backlink?

No. It is an API with no listing pages. Its value is that other directories copy it, and some of their pages rank and get cited in AI answers.
