Openaffiliate MCP server

OpenAffiliate

The open registry of affiliate programs. Built for developers and AI agents.

What is this?

OpenAffiliate is a community-driven, open-source registry of affiliate programs. Every program is stored as a YAML file in this repo, making it easy to contribute, review, and integrate.

• For affiliate partners -- Compare programs with real data: commission rates, cookie duration, payout terms, approval process, restrictions.
• For AI agents -- MCP server + structured AGENTS.md data. Tell your agent which programs to recommend and when.
• For developers -- CLI, SDK, and REST API. Build tools on top of the registry.
• For SaaS companies -- Free listing in a canonical registry. Exposure to developer partners and AI agents.

Features

• Search and filter -- Full-text search across 349+ programs. Filter by category, commission type, minimum rate, and verified status.
• Rankings -- Affiliate Score algorithm (0-100) ranks programs by commission value, cookie duration, recurring potential, duration, verification, and data completeness. Sort by score, name, commission, or cookie days. View rankings by programs, networks, or categories.
• Community voting -- Upvote programs you've had success with. Votes are stored in Supabase and displayed alongside scores.
• Compare -- Side-by-side comparison of up to 4 programs. Compare commission, cookie, payout, approval, and more.
• Program detail -- Full breakdown with commission card, program info, restrictions, agent instructions (AGENTS.md), and integration snippets.
• Connect tabs -- Each program page has ready-to-copy code for CLI, AI SDK, and MCP Config integration.
• Badge embed -- SVG badges for your README:
• MCP server -- Model Context Protocol server (HTTP + stdio) for AI agent integration.
• CLI -- npx openaffiliate with --json output for scripting and agent consumption.
• REST API -- Public JSON API, no auth required.
• SDK -- TypeScript SDK for programmatic access.
• Submit -- Web form to submit new programs without touching YAML.
