bvb-mcp

Read-only MCP server for the Bucharest Stock Exchange (Bursa de Valori București, BVB). It exposes BVB's own public backend — the TradingView-UDF datafeed at wapi.bvb.ro and the market-list pages at www.bvb.ro — as MCP tools: instrument universe, symbol search and metadata, and OHLCV candles.

No account, no API key, no token: the BVB backend is public and unauthenticated. Every tool is read-only; there is nothing to trade through here.

Features

• OHLCV candles for any BVB ticker or index (get_candles), with a clean resolution parameter that hides the datafeed's 1D-not-D quirk.
• Full instrument universe scraped from the exchange's market-list pages (list_instruments) — ticker + ISIN + name — plus the index universe (list_indices).
• Datafeed symbol search (search_symbol) and per-symbol metadata (get_symbol_info), with diagnostics (server_time, datafeed_config).
• Browser-like User-Agent and Referer: https://www.bvb.ro/ on every request (defensive; no cookies, no token).
• One automatic retry on HTTP 429, honouring Retry-After (capped at 30s).
• stdio transport by default, HTTP (/mcp) on request.

Tools

All tools are read-only (there are no write tools):

Tool	Description
list_instruments	List a market's instrument universe (ticker + ISIN + name) by scraping the BVB market-list page. Markets: shares, bonds, fund-units (ETFs), warrants, certificates (structured)
list_indices	List the BVB index universe (BET, BET-TR, BET-FI, ROTX, …)
search_symbol	Datafeed symbol search by ticker/name (server-capped at ~30 results)
get_symbol_info	Resolve a ticker to its metadata: name, type, session, timezone, currency, sector/industry
get_candles	OHLCV candles for a ticker/index at minute/daily/weekly/monthly resolution
get_fundamentals	Company details + valuation snapshot scraped from the detail page: identity, Indicatori bursieri (market cap, P/E, P/BV, EPS, div yield, dividend), issue info, and ownership structure
financial_summary	One-call bundle for a fundamental ("Buffett-style") analysis: get_fundamentals + a price summary (last close, 52-week range, 1y/5y change). Returns data, not a verdict
server_time	Datafeed server time (reachability check)
datafeed_config	Datafeed configuration: instrument-type codes and supported resolutions

Notes on the data surface

• Search is capped. search_symbol mirrors the datafeed's own search, which returns roughly 30 results for broad queries. Use list_instruments (or list_indices) to enumerate the full universe.
• The 1D quirk. The datafeed advertises a bare D for daily bars but the history endpoint only accepts 1D (bare D returns HTTP 500). get_candles takes a friendly resolution (1, 5, 15, 30, 60, 1D, 1W, 1M; D/W/M are accepted too) and sends the correct code.
• Index metadata is partial. list_indices always returns every index's symbol, but name/isin are populated only for the indices BVB renders a server-side profile card for; the rest load via client-side tabs and come back as null.
• Rights / structured. BVB publishes no standalone "rights" market page, and "structured products" (datafeed type T) are split across the warrants and certificates pages — structured is accepted as an alias for certificates.
• No multi-year statements. get_fundamentals / financial_summary expose BVB's current snapshot (valuation ratios, dividend, ownership) — BVB does not publish structured multi-year income/balance/cash-flow statements, so a full 10-year ROE/margin/FCF track record is not available. Pair with get_candles for the price trend; the client (LLM) does the analysis.

Configuration

All configuration is via environment variables, and all of it is optional — the BVB backend needs no credentials.

Variable	Default	Purpose
BVB_DATAFEED_URL	https://wapi.bvb.ro	Datafeed base URL
BVB_WEB_URL	https://www.bvb.ro	Market-list site base URL
BVB_MCP_USER_AGENT	a Chrome-like UA	User-Agent sent on every request
BVB_LANG	ro	Language for the datafeed config endpoint

Getting started

Run straight from the repository with uv:

uvx --from git+https://github.com/florinel-chis/bvb-mcp bvb-mcp

The server speaks stdio by default; add --transport http --port 8000 to serve MCP over HTTP at /mcp instead. HTTP binds 127.0.0.1 by default, and a non-loopback --host is refused unless --allow-remote is also passed — read the Safety section before using that flag.

MCP client configuration

Add the server to your MCP client's configuration (stdio, via uvx):

{
  "mcpServers": {
    "bvb": {
      "command": "uvx",
      "args": ["--from", "git+https://github.com/florinel-chis/bvb-mcp", "bvb-mcp"]
    }
  }
}

Or run the Docker image (build it first, see below):

{
  "mcpServers": {
    "bvb": {
      "command": "docker",
      "args": ["run", "-i", "--rm", "bvb-mcp"]
    }
  }
}

Docker

A small (~200 MB) multi-stage image that works both ways an MCP client might use it — spawned per call over stdio, or as a long-running HTTP server. Both paths are verified against BVB's live backend. The container only needs outbound network to reach wapi.bvb.ro / www.bvb.ro; no credentials or volumes.

Build:

docker build -t bvb-mcp .

stdio — what an MCP client spawns (use bvb-mcp as the image name in the docker config above):

docker run -i --rm bvb-mcp

HTTP — a shared, long-running server at http://127.0.0.1:8000/mcp/:

docker run --rm -p 127.0.0.1:8000:8000 bvb-mcp \
  --transport http --host 0.0.0.0 --port 8000 --allow-remote

--host 0.0.0.0 binds inside the container so the port mapping works — which is why --allow-remote is needed; the 127.0.0.1: prefix on -p keeps the endpoint reachable from this machine only (it is unauthenticated — see Safety). If host port 8000 is taken, map another, e.g. -p 127.0.0.1:8010:8000.

Share without a registry — hand the image to someone as a file they docker load, no Docker Hub / GHCR needed:

docker save bvb-mcp:latest | gzip > bvb-mcp.tar.gz   # you: export
docker load < bvb-mcp.tar.gz                          # them: image is now local

Safety

• The HTTP transport has no authentication: anyone who can reach the /mcp endpoint can call every tool. Keep it bound to 127.0.0.1 (the CLI default; with Docker, publish as -p 127.0.0.1:8000:8000) or put it behind an authenticating reverse proxy. Never expose it directly on a public network.
• All tools are read-only — this server cannot place orders or move money.
• Use at your own risk. Nothing here is investment advice.

Data & terms

This server ships code, not data. It fetches from BVB's own public backend at request time and returns whatever BVB serves. Redistributing or otherwise using BVB price data is subject to BVB's terms and any applicable market-data licensing, and is your responsibility as the operator — the software makes no representation about your right to store, redistribute, or trade on the data it relays.

Development

uv sync
uv run pytest -q
uv run ruff check .

Tests are fully offline: HTTP is stubbed with respx against captured BVB response fixtures in tests/fixtures/.
