Common questions

Is Serpier safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.3) reached the registry 7 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

Serpier MCP server

Serpier is an SEO platform for marketing teams and agencies. The Serpier MCP server lets an AI assistant work in your Serpier account: monitor your brand's AI Visibility and SEO performance, track published articles, and find publishers and manage link-building orders.

This is a hosted, remote MCP server. There is nothing to install or run. This repository holds the connection details and the metadata that MCP registries and directories read.

Server URLhttps://app.serpier.com/api/mcp
TransportStreamable HTTP
AuthenticationOAuth 2.1 with PKCE. Dynamic Client Registration and Client ID Metadata Documents are supported.
Registry namecom.serpier/serpier
Docsdocs.serpier.com/mcp

What the assistant can do

  • AI Visibility: see how often your brand is mentioned and cited in AI answers for the prompts you track, add or remove prompts, and start new analysis runs.
  • SEO Performance: follow keyword rankings, search traffic and backlinks for your website projects.
  • Publication tracking: check whether published articles are live, indexed and still linking to you, and add new articles to monitor.
  • Marketplace: search Serpier's catalog of vetted publishers by country, topic, price and authority.
  • Cart and orders: add publishers to your cart, place orders, follow order status and fill in the brief for each publication.
  • Projects: list and create the website projects in your organization.

Actions that change data are marked as such, so your assistant can ask you before running them. Placing an order is a real purchase, paid by card or invoice.

Connect

You need a Serpier account. Sign up at serpier.com. When your client connects for the first time, it opens Serpier in your browser. Sign in, choose the organization and team, and allow access. You never paste a key.

Claude

In Settings > Connectors, select Add custom connector, name it Serpier, and paste the server URL.

ChatGPT

Add a custom app with the server URL, then select Authenticate and sign in to Serpier.

Claude Code

Install the Serpier plugin:

/plugin install serpier --marketplace Serpier/serpier-mcp

Or add the server by hand:

claude mcp add --transport http serpier https://app.serpier.com/api/mcp

Then run /mcp in Claude Code, select serpier, and sign in.

Cursor, VS Code and other clients

Add the server to your client's MCP configuration (mcp.json):

{

"mcpServers": { "serpier": { "type": "http", "url": "https://app.serpier.com/api/mcp" } } }

VS Code uses servers as the top-level key instead of mcpServers.

Gemini CLI
gemini extensions install https://github.com/Serpier/serpier-mcp
Personal access token

You can also connect with a personal access token, sent in the x-api-key header. Personal access tokens need the Enterprise plan; see Create a personal access token.
