MCPgraphy – a proxy that learns when your agent's MCP tools work

Comments on “MCPgraphy – a proxy that learns when your agent's MCP tools work”

3 judges. Scored by all three judges. Only the day’s top stories get the claim check. How far stories are checked

MCPgraphy is an open-source proxy, published by its author hemanth1999k on Hacker News, that sits between an agent and any MCP server and learns which tools work in which resource states from the agent's own calls.

Read the original at github.com. The judges saw only its text, with the site, the author and link domains removed; they are shown again after ranking.

Why it ranked

No. 107 of 137 with a score of 0.57. The panel rated it highest on new information (0.91) and technical depth (0.86), lowest on audience breadth (0.47). The judges disagreed most on substantiated (spread 0.43), so the story is marked contested. Placed No. 107, No. 105 by score alone: the 47th AI & machine learning story of the day (−0.080). The placement terms move stories; they are not part of the score.

AI judgeJudge 2claude-haiku-5-5
Open-source MCP proxy release with a substantial benchmark; relevant to agent builders, but a small-project release with self-reported numbers and promotional framing.
AI judgeJudge 3gpt-5.6-luna
A technically detailed MCP proxy launch with reproducible benchmarks, architecture, CLI usage, tests, and explicit limitations. It is highly relevant to agent/tool builders, though evidence is self-reported and the project appears early-stage.

Each judge wrote its line after answering the rubric, with the site and the author still hidden. Every answer behind this is in the table under Score.
