Specter MCP - Installation Guide | Specter Help Center

What is an MCP?

Model Context Protocol (MCP) is a standard for connecting AI clients (like Notion AI or Claude Desktop) to external tools and data sources (“MCP servers”).

When you connect to Specter MCP from your AI client, you’re granting Specter MCP permission to act on your behalf within the scope you approve.

Claude Desktop: adding Specter MCP to your connectors

Head over to Customize → Connectors

From your Claude’s home page, head over to “Chat” and then to “Customize”

And then to “Connectors”. From there, you should see a Plus (”+”) button. Click it, and a sub-menu should appear, with “Add custom connector”. If you don’t see it, contact your organization administrator.

A popup will appear, asking to add a custom connector.

Please, use the following values:

Name: “Specter”
Remote MCP server URL: https://mcp.tryspecter.com/mcp

You should see the Specter added to your list of custom connectors.

Adding Specter MCP to Claude Code

Option 1: Use `claude` CLI

Head over to your terminal, and execute the following command:

claude mcp add --transport http specter https://mcp.tryspecter.com/mcp

Option 2: modify ~/.claude/settings.json

Head over to your terminal, and modify the file ~/.claude/settings.json as follows:

{
  "mcpServers": {
    "specter": {
      "url": "https://mcp.tryspecter.com/mcp"
    }
  }
}

After that, restart claude code. You should be able to see and authenticate to the Specter.
