Serpel

Serpel plugin for AI assistants

Ask Claude, ChatGPT, Codex, Cursor, GitHub Copilot, VS Code or the Gemini CLI about the SEO data of your own websites. The plugin connects your assistant to the Serpel MCP server and adds a skill that explains which tool to use when.

The plugin contains manifests and one skill only. It has no program code and no hooks.

What you can ask

• Which projects do I have, and how healthy is each one?
• Which keywords moved up or down since the last rank check?
• What do Google Search Console clicks and impressions look like compared with the previous period?
• Which queries rank on positions 4 to 20 and are quick wins?
• Where do my competitors rank better than I do?
• Which technical issues did the latest crawl find, and what should I fix first?
• How often is my site cited or mentioned in ChatGPT answers and in Google AI Overviews?
• Has my crawl or rank check finished?
• Optional, uses credits: keyword ideas with search volume, difficulty and intent.

Tools

All lists contain at most 25 rows. Tools only read data of projects you can access, and they never change your website.

ChatGPT does not offer research_keywords. In all other clients it needs an active Starter or Pro plan and the workspace setting “Agents can spend credits”. A daily credit limit for agents applies, and credits come from your monthly plan allowance first.

Interactive cards

In apps that can display MCP Apps, such as ChatGPT and Claude, four tools show their result as an interactive card: get_keyword_rankings, get_crawl_issues, find_keyword_opportunities and get_ai_visibility. Every other client, for example Claude Code, Cursor, Codex and the Gemini CLI, gets the same data as text. The cards load no external resources and open links only to the Serpel dashboard.

Set up

The server address is https://serpel.app/mcp (Streamable HTTP). Clients that support OAuth open a browser window for the sign-in on first use. Alternatively create an API token with the mcp:read permission (plus the read permissions for the data you want to use) in the Serpel dashboard under Settings, API tokens, and send it as Authorization: Bearer .

Claude Code

claude mcp add --transport http serpel https://serpel.app/mcp

To load the plugin with its skill from a local checkout: claude --plugin-dir ./serpel-plugin.

ChatGPT and Codex

Install the plugin from the plugin directory, or add the remote MCP server https://serpel.app/mcp in the connector settings and sign in with your Serpel account.

Cursor

Add the server in .cursor/mcp.json or install the plugin from the marketplace:

{

"mcpServers": { "serpel": { "url": "https://serpel.app/mcp" } } }

VS Code with GitHub Copilot

Add the server in .vscode/mcp.json or install it from the MCP gallery (@mcp):

{

"servers": { "serpel": { "type": "http", "url": "https://serpel.app/mcp" } } }

Gemini CLI

gemini extensions install https://github.com/Serpelapp/serpel-plugin
