Full-text Chinese national standards (GB/GB-T/GB-Z) via MCP, with legal force, normative reference chains and version history — so your agent reads the complete standard, not fragment chunks.
600+ standards · CCC/CE market access · 7 MCP tools · pay-per-use from $0.05

When your agent is asked "which clauses of GB 38031 apply to my EV battery?", most LLMs either hallucinate or return a vague summary. StdFlow gives your agent read access to the complete, official standard text — plus the metadata that matters for compliance:
- Full standard recall —
get_standardreturns the whole standard text (not chunks), so the agent understands the design logic, not just keywords. - Legal force + reference chains — every standard is tagged
mandatory/recommended/guideline, and normative references are traceable. A mandatory standard's referenced GB/T clauses are implicitly mandatory — the agent can reason this out from the data. - Version history — know whether you're looking at the current or superseded edition.
- Bilingual metadata — Chinese standards with English-ready metadata; the tool descriptions are bilingual.

}The agent can see that GB 15735 is mandatory and that the recommended GB/T standards it references become implicitly mandatory — this is the "invisible mandate" that compliance teams miss.
More scenarios: battery-safety, toy-safety, food-contact.
