Mcp2cli is a runtime approach — CLI translation at query time. There's a complementary build-time angle worth knowing about: fixing the schemas directly so they're token-efficient before they're ever served to a client.
We graded 201 MCP servers (3,991 tools, 512K tokens total). 97% have quality issues that waste tokens: descriptions that repeat the parameter name verbatim, markdown formatting inside tool descriptions, missing type info, descriptions starting with 'This tool...' or 'Allows you to...'. None of this helps the LLM; it just costs tokens.
agent-friend fix server.json > fixed.json reduces token count ~30% for most servers without changing functionality. The two approaches stack — fix the schema first, then serve via CLI if needed.
