Show HN: Save Context from MCP Bloat

Category: devtools

Tags: mcp, proxy, context-management

Score: 7.3/10 (Innovation: 6, Technical: 7, Documentation: 9, Utility: 7)

mcp-context-guard is a lightweight proxy for MCP servers that caches large tool responses and injects a `seek_result` tool to query them with jq or grep filters, preventing context window flooding. Its practical approach to a real MCP pain point, combined with a clean design supporting both local and remote servers with OAuth transparency, makes it a useful utility for AI tooling workflows.

Target audience: backend devs, AI engineers, devops
