MCP Gateway — Development skill for Claude Code

Development community

Local MCP gateway that fans out to N downstream MCP servers, namespaces tools, and lazy-loads schemas — so your coding agent's context isn't eaten by MCP boilerplate.

How to install MCP Gateway

README

mcp-gateway

**Your coding agent is spending 47,000 tokens on MCP boilerplate before you type a word.** `mcp-gateway` fans out to your downstream MCP servers, namespaces their tools, and only exposes what you ask for. Agents discover the rest on demand via `mcp_tool_search`.

Claude Code /context dropping from 47K to 3K tokens after installing mcp-gateway

30-second install

# Drop-in for Claude Code
npx @swarmclawai/mcp-gateway@latest add claude-code

# Or Cursor, Cline, Windsurf
npx @swarmclawai/mcp-gateway@latest add cursor
npx @swarmclawai/mcp-gateway@latest add cline
npx @swarmclawai/mcp-gateway@latest add windsurf

That edits the agent's MCP config (with a `.bak` backup) so it talks to one gateway endpoint instead of N individual servers. Then:

# Generate a starter config and edit to taste
npx @swarmclawai/mcp-gateway@latest init --write

# See how many tokens each downstream server is spending on tool schemas
npx @swarmclawai/mcp-gateway@latest token-report
