Feature & Specification Comparison

Specification	Diffgate srbsa Finance & Fintech	Pulsefeed X402 Nikolife2016 Finance & Fintech
Summary	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)	Trust & safety layer for x402 agent payments: before your agent pays an x402 endpoint, verify it is safe — liveness, scam/anomaly scan (payTo hijack, bait-and-switch, honeypot), and on-chain receiver verification. 70% of x402 endpoints are dead or scams; only half of "healthy" listings work. Free /verify + an open Trust Score. npx -y pulsefeed-x402-mcp

Tools & Capabilities Breakdown

Diffgate Tools (7)

diffgate_analyze

Analyze a file for code review findings. Only flags risk on lines changed vs the git baseline (diff-aware). Pass `content` to analyze unsaved or generated code before it is written to disk. When a code graph is available, public-surface findings carry an `impact` field (caller count, suggested reviewers, test gaps) and may be tier-adjusted — fix high-blast-radius findings before surfacing the code.

diffgate_check_staged

Check all staged (or working-tree) changes in a git repo for DiffGate findings. Returns overall tier, counts, and per-file findings across the whole diff, plus a `verdict` block (the agent autonomy ladder: pass/review/blocked overall, with a rung — block/escalate/autofix/advisory — per finding) so you can decide whether to surface the diff without reimplementing the rules.

diffgate_deep_review

Run an agentic deep review on a single high-impact (orange) finding. The model uses real repo tools (grep, read_file, find_references, git_blame) to investigate blast radius before rendering a verdict.

diffgate_explain

Get a concise AI explanation for a DiffGate finding. Faster than diffgate_deep_review — a single LLM call with no tool loops.
