Reddit-Threads finden und Antworten mit Claude Code oder Cursor entwerfen

The whole loop takes five steps: connect one MCP server, save your keywords and competitors, list today's threads, draft a reply, and paste it on Reddit yourself. This walkthrough uses Appie.run's MCP server, with every tool name and credit cost taken from appie.run/docs/mcp on 22 Oct 2026.

Disclosure: this post is published by Appie.run, and the server used here is ours. Other Reddit MCP servers exist; see our roundup of Reddit MCP servers for marketing. Appie drafts replies but never posts them.

In Appie, open the project and go to API in the sidebar. A project admin generates one esk_ key.

export APPIE_API_KEY = esk_YOUR_KEY Enter fullscreen mode Exit fullscreen mode Never commit the key or paste it in public.

The server is https://appie.run/mcp (streamable HTTP). It accepts Authorization: Bearer esk_... or X-Api-Key: esk_....

Cursor. Add this to your MCP config (from Appie's docs):

{ "mcpServers": { "appie": { "url": "https://appie.run/mcp", "headers": { "Authorization": "Bearer YOUR_API_KEY" } } } } Enter fullscreen mode Exit fullscreen mode Claude Code. One command:

claude mcp add --transport http appie https://appie.run/mcp \ --header "Authorization: Bearer $APPIE_API_KEY " Enter fullscreen mode Exit fullscreen mode --transport http is required; without it, Claude Code treats the URL as a local command. The default scope is local (you, this project). Add --scope user to use it everywhere. Your shell expands $APPIE_API_KEY, so the key itself is saved in ~/.claude.json.

To share the server with a repo without committing the key, use a project.mcp.json:

{ "mcpServers": { "appie": { "type": "http", "url": "https://appie.run/mcp", "headers": { "Authorization": "Bearer ${APPIE_API_KEY}" } } } } Enter fullscreen mode Exit fullscreen mode Check it with claude mcp list. With a valid key, the status should read Connected. Note that claude mcp get appie prints the header value in plain text, so don't share that output.

codex mcp add appie --url https://appie.run/mcp --bearer-token-env-var APPIE_API_KEY Enter fullscreen mode Exit fullscreen mode This writes the following to ~/.codex/config.toml:

[mcp_servers.appie] url = "https://appie.run/mcp" bearer_token_env_var = "APPIE_API_KEY" Enter fullscreen mode Exit fullscreen mode Codex stores only the variable name and reads the key each time it starts. codex mcp list reads the config but doesn't connect. Start codex and run /mcp to see the tools.

Smithery. Paste the key into the apiKey field. Smithery sends it as X-Api-Key.

The commands above were run against appie.run with a placeholder key (which returned the expected 401). The success output described here is what you should expect with a real key, not something we captured.

Ask your agent to call get_reddit_settings. It's free. If you haven't saved anything yet and your project Brain has a website, about text, key messages or competitors, Appie saves those as your Reddit settings and returns them. That gives you a starting point.

Then refine with update_reddit_settings (also free). Send only the fields you want to change: keywords, competitors or custom_prompt. Each list holds up to 25 items. Illustrative arguments:

{ "keywords": [ "reddit monitoring", "social listening for startups", "find leads on reddit", "brand mentions tool", "reply to reddit threads" ], "competitors": [ "CompetitorA", "CompetitorB", "CompetitorC" ], "custom_prompt": "Help first. Disclose that I work on the product. No links unless asked." } Enter fullscreen mode Exit fullscreen mode The docs don't say whether a list replaces or appends to what's saved. Send the full list each time, and check the response to see what was stored.

Call list_reddit_mentions. It lists Reddit threads for your saved keywords and competitors, with the latest reply draft for each. limit defaults to 20, maximum 50.

A scan runs at most once per day and costs 10 credits. Calling it again the same day lists results without a new scan. If your balance is too low, the result has scan_skipped: true and a message saying no scan ran.

This is a monitored feed of your terms, not a search of all of Reddit, and it isn't real-time.

Pick a mention and call draft_reddit_reply with its mention_id. It costs 2 credits and returns content (the draft) and source_url (the thread). Illustrative shape:

{ "content": "...", "source_url": "https://www.reddit.com/r/...", "credits_remaining": 488 } Enter fullscreen mode Exit fullscreen mode (The credits_remaining number is only an example.)

Appie doesn't post to Reddit. If you only need a one-off draft for a thread you found yourself, Appie's free AI Reply Generator takes the message, a style and a length, and returns an editable reply without any setup.

Worked example (illustrative arithmetic from the docs, not a promise of usage): a daily scan for 30 days is 300 credits, and 50 drafts are 100 credits. Together that's 400 of the Free plan's 500 credits. Paid plans are Starter at $19/month (2,000 credits) and Standard at $49/month (5,000 credits), per appie.run/pricing.

Add the server URL and an Authorization header to your Cursor MCP config, as in Step 2.

claude mcp add --transport http <name> <url> --header "Authorization: Bearer <key>".

Not with Appie. It drafts the reply, and you paste it yourself.

At most once per day, at 10 credits per scan.

Grab an API key, add https://appie.run/mcp to Cursor, and run your first Reddit scan on the Free plan's 500 credits: appie.run/docs/mcp. Skills and examples are also on GitHub.
