However you give your AI Reddit access, it comes down to three doors: an MCP connection (chat clients like Claude and Cursor), an OpenAPI import (ChatGPT Actions, Claude Code's shell), or a raw REST call (any language, any agent). Pick whichever matches the tool you're already using — here's one short snippet for each.
Door 1: MCP, for chat clients
Claude Code, Claude Desktop, Cursor, Codex, and other MCP clients can connect to a Reddit API as a set of tools. Claude Code:
claude mcp add --transport http threadsnoop https://api.threadsnoop.com/mcp \
--header "x-api-key: YOUR_KEY"Other MCP clients point at the same https://api.threadsnoop.com/mcp endpoint with an x-api-key header — details for Claude specifically: giving Claude access to Reddit.
Door 2: OpenAPI/Actions, for agents with a shell or a builder UI
ChatGPT's Custom GPT builder and shell-capable agents like Claude Code can both import a REST API straight from its spec — no MCP server involved:
https://api.threadsnoop.com/openapi.jsonAuth is the same x-api-key header either way. Full setup for each: connecting ChatGPT to Reddit and giving Claude Code access via an OpenAPI spec.
Door 3: raw REST, for any agent or script
No client integration at all — just an HTTP call any language or agent framework can make:
curl -s "https://api.threadsnoop.com/v1/posts?subreddit=SaaS&limit=25" \
-H "x-api-key: YOUR_KEY"This is the door for a custom agent loop or a script with no MCP or Actions support: using AI agents to search Reddit and the practical API guide.
All three doors hit the same read-only API, billed the same way — 1 credit per request, $1.50 per 1,000 reads, as low as $1.00/1,000 in bulk. New keys get $0.50 of free credit (333 reads), no card required, enough to try whichever door fits your AI.
Frequently asked questions
What's the easiest way to connect my AI to Reddit?
If your AI is a chat client — Claude, Cursor, Codex — connect it over MCP with one command or config block; it needs no code from you after that. If it's a Custom GPT or a shell-capable agent, import the OpenAPI spec instead.
Does it matter which AI or agent I'm using?
Not much — the doors map to capability, not brand. Any MCP-compatible client uses the MCP door; anything that can import an OpenAPI spec or make an HTTP call can use the other two, regardless of which company built it.
Do I need different Reddit access for each AI tool?
No — one API key works across all three doors and every tool. Create it once from /developer and reuse it whether you're connecting Claude, ChatGPT, Codex, or your own script.
