SlangLane MCP

SlangLane provides a read-only remote MCP server and API for accessing a dictionary of internet slang and usage. It allows agents to look up documented meanings, retrieve regional notes, identify terms in phrases, and filter content by maturity levels. The server offers tools for exact lookups, lexical search, phrase decoding, and usage comparison, ensuring responses include canonical citations and source links for verified context.

Claude Code

Run this once in a terminal. It registers a Streamable HTTP server. Use --scope project to write .mcp.json for the repo.

Claude Code configuration

claude mcp add --transport http slanglane-mcp https://slanglane.com/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).

Codex configuration

codex mcp add slanglane-mcp --url https://slanglane.com/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable slanglane-mcp in your MCP settings.

Cursor configuration

{
  "mcpServers": {
    "slanglane-mcp": {
      "url": "https://slanglane.com/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure). The type must be streamableHttp for a remote HTTP server.

Cline configuration

{
  "mcpServers": {
    "slanglane-mcp": {
      "type": "streamableHttp",
      "url": "https://slanglane.com/mcp",
      "disabled": false
    }

  "servers": {
    "slanglane-mcp": {
      "type": "http",
      "url": "https://slanglane.com/mcp"
    }

Gemini CLI configuration

gemini mcp add --transport http slanglane-mcp https://slanglane.com/mcp

Claude Desktop

Merge this into claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\), then restart Claude Desktop.

Claude Desktop configuration

  "mcpServers": {
    "slanglane-mcp": {
      "url": "https://slanglane.com/mcp"
    }
  }
}

Windsurf
