uvx reddit-no-auth-mcp-server

# HTTP transport
uvx reddit-no-auth-mcp-server \
  --transport streamable-http \
  --port 8000

2.2. From source

git clone https://github.com/eliasbiondo/reddit-mcp-server.git
cd reddit-mcp-server
uv sync

Run the server:

# stdio transport (default)
uv run reddit-no-auth-mcp-server

# HTTP transport
uv run reddit-no-auth-mcp-server \
  --transport streamable-http \
  --port 8000
