Wraps a single upstream MCP, forwards every call, and handle-ifies fat payloads into content-aware backends the agent can query with a small set of universal verbs ( peek , slice , search , aggregate , describe , list handles ). Benchmarks Measured end-to-end against two popular real-world MCP servers. Each run fires a fixed script of tool calls twice — once direct, once through jmunch-mcp — with three follow-up jmunch. verb calls on the proxied side to model an agent drilling into a large result rather than slurping it whole. suite upstream direct tokens via jmunch-mcp saved --- --- ---: ---: ---: GitHub ( facebook/react issues/PRs/commits) @modelcontextprotocol/server-github 379,878 44,328 335,550 (88.3%) Firecrawl (Wikipedia scrapes + site map + search) firecrawl-mcp 259,574 2,928 256,646 (98.9%) Wall-clock time was also faster with the proxy on both suites, despite the extra verb calls — the agent never has to page through the fat payload: suite direct via jmunch-mcp delta --- ---: ---: ---: GitHub 8.4s 6.8s −1.6s (−19.0%) Firecrawl 16.4s 9.2s −7.2s (−43.9%) Tabular content (GitHub) routes to the SQLite backend and answers peek / slice / aggregate ; JSON content (Firecrawl scrape/map) routes to the JSON-tree backend and answers peek / slice (JSONPath)/ search .
