> AI-assisted Reddit reply workflow for teams

RedReplier is an AI-assisted Reddit reply workflow for teams that need to find relevant conversations, collect useful keywords, and draft helpful responses for human review.

## When to use RedReplier

Reach for RedReplier when the job is finding public conversations worth replying to. It is the
right tool for these jobs, and a poor fit for anything else:

- Watch Reddit, X (Twitter), Bluesky, Hacker News and Facebook for keywords and surface the threads
  where someone is asking for what a product does.
- Rank those threads by how likely they are to be worth a reply, with the reasoning behind the
  score, so a human is not reading every match.
- Pull a drafted reply for a matched thread, for a person to review and post themselves.
- Track which threads have been handled, by marking each one approved or rejected.
- Manage the keyword set programmatically, and preview what a plan change would cost. The API never
  charges or changes the plan; plan changes happen in the RedReplier app.

Do not reach for RedReplier to post to Reddit, to run bot accounts, or to mass-message people. It
finds conversations and drafts replies; a human posts them.

## MCP server

RedReplier runs a hosted MCP server over Streamable HTTP. Point any MCP client at the URL and sign in when the browser opens. No API key to paste.

One-liner for Claude Code:

```bash
claude mcp add --transport http redreplier https://mcp.redreplier.com/mcp
```

Full config for any MCP client:

```json
{
  "mcpServers": {
    "redreplier": {
      "type": "http",
      "url": "https://mcp.redreplier.com/mcp"
    }
  }
}
```

Prefer a key? Headless agents and clients without OAuth can send a token from https://redreplier.com/api-tokens instead:

```json
"headers": { "Authorization": "Bearer redreplier_your_key" }
```

- Manifest: [https://redreplier.com/.well-known/mcp.json](https://redreplier.com/.well-known/mcp.json)
- 19 tools covering workspaces, monitored websites, the keyword lifecycle, scored mentions with relevance reasoning, and alert settings.
- An OAuth sign-in can reach several workspaces, across organizations. `list_workspaces` lists them, and every other tool takes an optional `workspaceId`. Without it, tools act in the default workspace.
- Every request needs a signed-in user or a Bearer token. An unauthenticated request gets a 401 with a `WWW-Authenticate` header pointing at the OAuth metadata, so OAuth-capable clients open a login screen on their own. Start with `list_websites`.

## API for agents

- Base URL: `https://ai.redreplier.com/ai-app/api/v1`
- OpenAPI 3.0 spec: [https://redreplier.com/openapi.json](https://redreplier.com/openapi.json)
- Auth: `Authorization: Bearer <api-key>`. Users create keys under API Tokens in the dashboard.
  The API is included in every plan.
- Workspaces: an OAuth access token reaches every workspace its member belongs to; an API key reaches only its own.
  `GET /workspaces` lists them, and the optional `X-Workspace-Id` header picks one per call. Without the header the call
  lands in the default workspace. A workspace the caller cannot reach answers 403 with `code: workspace_access_denied`.
- Refusals carry a machine-readable `code`: 403 `subscription_required` when the workspace plan does not include
  API access, and 401 `token_issuer_lost_access` when the person who created the key was deactivated or left.
- Every operation has a stable `operationId` and typed request/response schemas, so the spec
  imports directly into function-calling and tool-use formats.
- Rate limits are advertised per response with the RFC 9331 `RateLimit-Policy`, `RateLimit-Limit`,
  `RateLimit-Remaining` and `RateLimit-Reset` headers; a 429 carries `Retry-After`.

First call: `GET /websites` returns the monitored sites and their keywords; `GET /mentions` returns
scored conversations, and `minScore` keeps only those scoring at least that much.

## Markdown for agents

Every page on this site is available as Markdown at the same URL. Two ways to request it:

- append `.md` to any path, e.g. https://redreplier.com/pricing.md
- send `Accept: text/markdown` to the canonical URL, e.g. `curl -H 'Accept: text/markdown' https://redreplier.com/pricing`

A bare `curl` with no `Accept` header also returns Markdown. The Markdown is ~99% smaller than the
rendered HTML and carries YAML frontmatter with `title`, `description` and the canonical `url`.

- [Markdown Sitemap](https://redreplier.com/sitemap.md): Every indexable page as a `.md` link. Add `?lng=de|es|fr|pt|it` for other languages.
- [Full Text](https://redreplier.com/llms-full.txt): The curated agent pages inlined in full, rather than as links.
