Serpel gives developers three ways in: a REST API, a CLI with JSON output and an MCP server for coding agents. All three use the same projects, data and credits as the dashboard.

- [Rank tracking API](https://serpel.app/developers/rank-tracking-api): Serpel’s rank tracking API adds keywords, runs Google rank checks and returns positions as JSON, for desktop and mobile, with locations and history.
- [SEO API](https://serpel.app/developers/api): Serpel’s SEO API is a REST API for rank tracking, site audits, AI visibility and search data, with bearer tokens, JSON responses and credit-based pricing.
- [MCP server](https://serpel.app/developers/mcp): Serpel’s SEO MCP server gives Claude Code, Cursor and other agents your rankings, audits and search data, with OAuth and a budget for paid tools.
- [CLI](https://serpel.app/developers/cli): The Serpel SEO CLI runs rank checks, site audits and AI visibility checks from your terminal, with JSON output, documented exit codes and CI support.
