banhmi crawls official government sources, extracts legal documents into a citable RAG corpus, and serves evidence over MCP — exact citations, validity, amendment relations, provenance, and coverage gaps. Multi-jurisdiction: Vietnam (banhmi), Malaysia (laksa) and Indonesia (rendang) are live; Thailand and Singapore are planned.

> banhmi does not answer questions. Your agent/model connects over MCP, retrieves citations and > validity, and decides the answer. No built-in LLM — repealed/superseded text is badged, never served > as current.

Use it over MCP — live, free, no signup

Remote MCP (Streamable HTTP), public, HTTPS, no key:

| Jurisdiction | MCP endpoint | Ask in | Official sources | |---|---|---|---| | 🥖 Vietnam | https://banhmi.danny.vn/mcp | English or Vietnamese | VBPL · Công Báo · vanban.chinhphu · SBV | | 🍜 Malaysia | https://laksa.danny.vn/mcp | English | AGC Laws of Malaysia · Bank Negara Malaysia · Securities Commission | | 🍛 Indonesia | https://rendang.danny.vn/mcp | Indonesian | JDIH BPK · Bank Indonesia · OJK |

Add as a custom connector (pick an endpoint above):

1. Claude (Pro/Max/Team/Enterprise) → Settings → Connectors → Add custom connector → paste URL, no auth.
2. ChatGPT (Plus/Pro/Team/Edu) → Developer mode → Settings → Apps & Connectors → Add → paste URL, no auth.
3. Grok → Settings → Connectors → Add MCP server → paste URL.
4. Gemini CLI → add under mcpServers in ~/.gemini/settings.json (httpUrl = endpoint).

No account or API key needed. Ask e.g. "What are the technology risk management requirements for banks?" — you get ranked provisions with citation, validity badge, and official source link.

Tools: search · document · corpus_status · quality_gaps · guide.

What it does

• Scope-filtered discovery of banking & financial regulation and cross-cutting technology law

(e.g. cybersecurity, data protection, AI, cloud, e-transactions, payments, digital banking).

• Verbatim authoritative sources — reconciled into one document per act, never paraphrased.
• High-fidelity extraction — go-fitz (MuPDF) for DOCX/HTML/born-digital PDF; Google Vision OCR or

EasyOCR (batched, cached) for scanned PDFs.

• Evidence, not answers — exact citations (VN Điều/Khoản, MY Section/Subsection, ID Pasal/ayat),

validity badges, confirmed relations, provenance, and gaps.

• Change tracking — amendments, repeals, subsidiary legislation, validity over time.
• MCP query surface — any agent connects, retrieves evidence, decides the answer.

Official data sources

Public legal data, crawled politely. Sources are pluggable — add your own under pkg/ingest/. See [docs/design/SOURCES.md](docs/design/SOURCES.md) and [docs/design/jurisdictions/](docs/design/jurisdictions/README.md).

Medallion pipeline (Bronze → Silver → Gold):

1. Discover → Fetch (Bronze): scope-filtered crawl; download raw files.
2. Extract → Normalize (Silver): go-fitz / MuPDF (scanned PDFs via Vision OCR / EasyOCR, batched

and cached); parse provision tree, validity, relations.

1. Index (Gold): chunk by article + Qwen3-Embedding (ONNX FP16, 1024 dims) into pgvector.

Hybrid retrieval — dense vectors + BM25 sparse vectors (sparsevec), RRF-fused with a query router, current-law pre-filter.

1. Serve: AWS CloudFront → ECS on EC2 Graviton (in-process Qwen3-Embedding ONNX), same VPC as

RDS (Singapore, PG17). Each domain's GET / serves a guide page; /mcp serves agents.

Status

MVP1 — three jurisdictions live. Validation and hardening ongoing.

| Jurisdiction | Endpoint | Sources | Status | |---|---|---|---| | 🥖 Vietnam | banhmi.danny.vn/mcp | vbpl · congbao · vanban · SBV | Live | | 🍜 Malaysia | laksa.danny.vn/mcp | AGC LOM · BNM · SC | Live | | 🍛 Indonesia | rendang.danny.vn/mcp | BPK · BI · OJK (×2) | Live | | 🇸🇬 Singapore | — | — | Proposed | | 🇹🇭 Thailand | — | — | Proposed |

See [PLAN.md](PLAN.md) for the roadmap.

Self-host

Everything runs in podman — full guide in [docs/DEVELOPMENT.md](docs/DEVELOPMENT.md).

cp config/config.example.yaml config/config.yaml
export BANHMI_DATABASE_PASSWORD=banhmi
make dev-up        # Postgres+pgvector
make migrate       # apply schema
go run ./cmd/seed  # load config vocabularies

Build the corpus and serve MCP per [docs/DEVELOPMENT.md](docs/DEVELOPMENT.md). A fresh clone reaches ingesting + serving with no API keys. Deploy via [docs/DEPLOYMENT.md](docs/DEPLOYMENT.md).
