Fee intelligence with USD conversion and send-now-or-wait advice, mempool analysis, mining pool rankings, market sentiment, block/transaction inspection, and BTC price. Your local node or hosted via Satoshi API (zero install).	Deterministic guardrail for AI-written diffs, runnable from inside the coding agent's own loop over MCP. Zero-LLM-token, AST-precise rules (SQLi, SSRF, XXE, permissive CORS, prototype pollution, hardcoded secrets) across 8 languages, plus structural checks for reinvented helpers and over-abstraction — findings scoped to only the changed lines, same input always gives the same output, no false-block guarantee. npm i -g diffgate-review (registers as the diffgate command; diffgate mcp starts the server)
