🔌 Installation

Installing via Smithery

To install Reddit Content Integration Server for Claude Desktop automatically via Smithery:

npx -y @smithery/cli install reddit-mcp-server --client claude

Manual Installation

git clone https://github.com/jordanburke/reddit-mcp-server
Create a Reddit app here

Make sure to select "script"!

Copy the client ID and client secret
Create a .env file based on .env.example

Do this with your REDDIT_CLIENT_ID and REDDIT_CLIENT_SECRET

If you want to write posts you need to include your REDDIT_USERNAME and REDDIT_PASSWORD

Install dependencies with pnpm install
Build the project with pnpm build
Run with pnpm dev and open the inspection server (http://127.0.0.1:6274/)

If the connection works, add this to your MCP config (for Cursor or Claude Desktop)

HTTP MCP Endpoint (FastMCP)

In addition to the standard npx execution, this server supports HTTP transport via FastMCP for direct HTTP integration:

# Start the HTTP server on port 3000 (default)
node dist/index.js

# Start with custom port
PORT=8080 node dist/index.js

# Or use the npm script
pnpm start

The server will be available at http://localhost:3000 with the MCP endpoint at http://localhost:3000/mcp.

OAuth Security (Optional)

The HTTP server supports optional OAuth protection to secure your endpoints:

Generate a secure token:

npx reddit-mcp-server --generate-token
# Output: Generated OAuth token: A8f2Kp9x3NmQ7vR4tL6eZ1sW5yB8hC2j

Enable OAuth with generated token:

export OAUTH_ENABLED=true
export OAUTH_TOKEN="A8f2Kp9x3NmQ7vR4tL6eZ1sW5yB8hC2j"
pnpm serve

Make authenticated requests:

curl -H "Authorization: Bearer A8f2Kp9x3NmQ7vR4tL6eZ1sW5yB8hC2j" \
     -H "Content-Type: application/json" \
     -d '{"method":"tools/list","params":{}}' \
     http://localhost:3000/mcp

OAuth Configuration:

OAUTH_ENABLED=true - Enables OAuth protection (disabled by default)
OAUTH_TOKEN=your-token - Your custom token (or use --generate-token)
Without OAuth, the server is accessible without authentication
Health check (/) is always unprotected; only /mcp requires authentication

MCP Client Configuration

For MCP clients connecting to an OAuth-protected server, configure according to the MCP Authorization specification:

HTTP-based MCP Clients (e.g., web applications):

// Example using fetch API
const response = await fetch("http://localhost:3000/mcp", {
  method: "POST",
  headers: {
    Authorization: "Bearer YOUR_TOKEN",
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    jsonrpc: "2.0",
    id: 1,
    method: "tools/list",
    params: {},
  }),
})

const result = await response.json()

Direct HTTP MCP Client:

const client = new MCP.Client({
  transport: new MCP.HTTPTransport({
    url: "http://localhost:3000/mcp",
    headers: {
      Authorization: "Bearer YOUR_TOKEN",
    },
  }),
})

Custom MCP Client Implementation:

import { Client } from "@modelcontextprotocol/sdk/client/index.js"
import { HTTPTransport } from "@modelcontextprotocol/sdk/client/http.js"

const transport = new HTTPTransport({
  url: "http://localhost:3000/mcp",
  headers: {
    Authorization: "Bearer YOUR_TOKEN",
    "Content-Type": "application/json",
  },
})

const client = new Client(
  {
    name: "reddit-client",
    version: "1.0.0",
  },
  {
    capabilities: {},
  },
)

await client.connect(transport)

Important Notes:

Replace YOUR_TOKEN with your generated OAuth token
Authorization header MUST be included in every request to /mcp
Tokens MUST NOT be included in URI query strings per MCP specification
Use HTTPS in production for secure token transmission

For Remote/Deployed Servers: When connecting to a remote Reddit MCP server (e.g., deployed on your infrastructure):

// Production server with OAuth
const response = await fetch("https://your-server.com/mcp", {
  method: "POST",
  headers: {
    Authorization: "Bearer YOUR_TOKEN",
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    jsonrpc: "2.0",
    id: 1,
    method: "tools/list",
    params: {},
  }),
})

MCP Client Configuration for Remote Server:

import { Client } from "@modelcontextprotocol/sdk/client/index.js"
import { HTTPTransport } from "@modelcontextprotocol/sdk/client/http.js"

// For your deployed server
const transport = new HTTPTransport({
  url: "https://your-reddit-mcp.company.com/mcp",
  headers: {
    Authorization: "Bearer YOUR_GENERATED_TOKEN",
    "Content-Type": "application/json",
  },
})

const client = new Client(
  {
    name: "reddit-client",
    version: "1.0.0",
  },
  {
    capabilities: {},
  },
)

await client.connect(transport)

Claude Desktop/Cursor with Remote Server (HTTP): For remote servers, you can use a proxy approach:

{
  "mcpServers": {
    "reddit-remote": {
      "command": "node",
      "args": [
        "-e",
        "const http = require('https'); const req = http.request('https://your-server.com/mcp', {method:'POST',headers:{'Authorization':'Bearer YOUR_TOKEN','Content-Type':'application/json'}}, res => res.pipe(process.stdout)); process.stdin.pipe(req);"
      ],
      "env": {}
    }
  }
}

For Claude Desktop/Cursor (stdio transport): OAuth is not applicable when using the traditional npx execution method. Use the stdio configuration instead:

{
  "mcpServers": {
    "reddit": {
      "command": "npx",
      "args": ["reddit-mcp-server"],
      "env": {
        "REDDIT_CLIENT_ID": "your_client_id",
        "REDDIT_CLIENT_SECRET": "your_client_secret"
      }
    }
  }
}

Remote Deployment Examples

Deploy to your infrastructure and share the URL:

Generate secure token:

npx reddit-mcp-server --generate-token
# Output: Generated OAuth token: xyz123abc456def789

Deploy with Docker on your server:

docker run -d \
  --name reddit-mcp \
  -p 3000:3000 \
  -e REDDIT_CLIENT_ID=your_reddit_client_id \
  -e REDDIT_CLIENT_SECRET=your_reddit_client_secret \
  -e OAUTH_ENABLED=true \
  -e OAUTH_TOKEN=xyz123abc456def789 \
  ghcr.io/jordanburke/reddit-mcp-server:latest

Share with your team:

Server URL: https://your-server.com/mcp
OAuth Token: xyz123abc456def789

Team members connect:

const client = new Client(...);
const transport = new HTTPTransport({
  url: 'https://your-server.com/mcp',
  headers: { 'Authorization': 'Bearer xyz123abc456def789' }
});
await client.connect(transport);

This allows integration with systems that support HTTP-based MCP communication via the FastMCP framework.
