OneMCP Show HN: Collapse 480 Tool Definitions Into Three Meta-Tools and Cut ~90% of Agent System Prompt Context
OneMCP posted to Show HN on Aug 23, unifying 20+ MCP servers (GitHub, Slack, Postgres, Linear, Notion, Jira, Stripe, Sentry and others) behind one portal endpoint exposing only search, describe and execute. Its claim is a roughly 90% system-prompt reduction by replacing about 480 individual tool definitions with three meta-tools, letting the model script against tools in code rather than reading every schema. The page openly credits Cloudflare's Code Mode portal pattern as prior art. Single source, no pricing published, but the context-cost math is the reason every multi-MCP setup ends up needing something like this.
