MCP Lite Wrappers

Lightweight MCP wrapper plugins that consolidate multiple tools into single-action tools, reducing Claude Code context usage by ~80%.

Problem

MCP servers expose many individual tools, each consuming context tokens. For example, supabase-mcp exposes 20+ tools, using ~11k tokens just for tool definitions.

Solution

Wrap multiple tools into a single tool with an action parameter. One tool, one description, massive token savings.

Before: 20 tools × ~500 tokens = ~10,000 tokens After: 1 tool × ~1,000 tokens = ~1,000 tokens Savings: ~80%

Installation

supabase-lite-mcp

npm install supabase-lite-mcp

Add to your Claude Code MCP config (~/.claude/settings.json or project .mcp.json):

{ "mcpServers": { "supabase": { "command": "npx", "args": ["supabase-lite-mcp"], "env": { "SUPABASE_ACCESS_TOKEN": "your-access-token", "SUPABASE_PROJECT_REF": "your-project-ref" } } } }

linear-lite-mcp

npm install linear-lite-mcp

Add to your Claude Code MCP config:

{ "mcpServers": { "linear": { "command": "npx", "args": ["linear-lite-mcp"], "env": { "LINEAR_API_KEY": "lin_api_xxxxx" } } } }

Get your Linear API key from Linear Settings > API.

chrome-lite-mcp

npm install chrome-lite-mcp

Add to your Claude Code MCP config:

{ "mcpServers": { "chrome": { "command": "npx", "args": ["chrome-lite-mcp"], "env": { "CHROME_PATH": "/path/to/chrome", "CHROME_HEADLESS": "true" } } } }

Environment variables (optional):

  • CHROME_PATH - Path to Chrome executable (auto-detected if not set)

  • CHROME_HEADLESS - Set to "false" for visible browser (default: headless)

context7-lite-mcp

npm install context7-lite-mcp

Add to your Claude Code MCP config:

{ "mcpServers": { "context7": { "command": "npx", "args": ["context7-lite-mcp"], "env": { "CONTEXT7_API_KEY": "your-api-key" } } } }

Environment variables (optional):

Architecture

Follows the superpowers-chrome pattern:

  1. Single tool with action enum parameter

  2. Switch/dispatch based on action

  3. Proxy calls to underlying API (Supabase Management API, Linear GraphQL API)
