Profile

Modern MCP agents often blow past context limits because tools return huge blobs (DOM dumps, network traces, screenshots, etc.). MCP Compact is a small proxy that sits between your agent and the upstream MCP server, forwards every tool call, and uses an LLM to summarize the response according to per-tool rules (token budget, fields to preserve/drop). It supports StreamableHTTP, tracks token usage, and can reconnect sessions, so you can keep agents focused without rewriting agent code or tools.

The company sits in the show hn launch segment, where it competes on its core product or service.

The company is listed at the Show HN launch stage of development.
