Feature & Specification Comparison

Specification	Klanex MCP chrassy Finance & Fintech	Diffgate srbsa Finance & Fintech
Summary	Reliable async execution for agent tool calls: schema-gate hallucinated payloads before they run, absorb rate limits and outages with retries/backoff/circuit breakers, idempotency keys, human approval gates, encrypted credentials, replay, and signed-webhook results. Errors come back with an llmhint the agent can self-correct from. Hosted remote (api.klanexai.com/mcp, free sandbox) or npx -y klanex-mcp.	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)
