Comparado con todos los servidores activos de esta categoría en el registro. Las estrellas solo cuentan cuando quien lo publica es dueño del repo.
Superó 0 de 1 revisiones básicas aplicables. No hemos leído el código. Antes de agregar una clave o un token, revisa qué acceso pide el servidor y usa una clave que tenga solo los permisos que necesitas.
El registro no indica ninguna clave obligatoria, aunque algunos servidores te piden iniciar sesión la primera vez que los usas.
Se ejecuta en la nube del creador. Te conectas por internet sin instalar nada, pero lo que envías pasa por los servidores del creador.
El repo de GitHub cambió por última vez –, y la última versión (0.6.24) llegó al registro hace 30 días.
Las apps compatibles con MCP, como Claude Desktop, Claude Code, Cursor y VS Code. Se conecta por URL, así que también funcionan las apps que aceptan servidores MCP remotos, como ChatGPT en modo desarrollador.

The remote MCP server is meant for directory listings and fast evaluation in ChatGPT Developer Mode, Cursor, Claude MCP clients, Smithery, Glama, and other Streamable HTTP clients.
It exposes only read-only discovery tools:
search_pairslist_instrumentsget_pricing_infoget_product_catalogrecommend_account_planget_workflow_endpointget_market_data_endpointsearchfetchThis public surface does not execute paid live market data calls directly.
The paid HTTP API is the production data path for live access:
GET /v1/vwap/{pair}GET /v1/bidask/{pair}GET /v1/fx/{pair}GET /v1/metal/{ticker}GET /v1/batchFree discovery endpoints:
GET /v1/coverageGET /v1/searchGET /v1/instruments/{service}GET /v1/samples/market-data?service=vwap&symbol=BTCUSD for a clearly synthetic value preview and attributed paid handoffGET /health/v1/search is paginated with limit and offset. Its total_matches field is the full match count for the searched catalogs; the default 50 is only the response page size and is unrelated to starter credits.
Payment modes:
PAYMENT-SIGNATURENew eligible authenticated users receive 30,000 free live data credits every calendar month (UTC), positioned as Start with 30,000 free live-data credits every month. The allowance is an evaluation and prototyping licence with required attribution; production commercial use requires a subscription. The number is configured once in FREE_TIER_MONTHLY_CREDITS (src/config.py) and every surface renders it from there. Raw caller-selected HTTP identity headers are disabled in production and cannot claim or spend credits. When the monthly allowance is exhausted, agents can use direct x402 payment, start a subscription trial at /go/free-trial (plans from EUR 49/month, see /go/pricing), or contact Blocksize sales about an Enterprise authenticated account plan.
Unit pricing is one list for both payment modes: 1 credit = $0.001 USDC, and every product costs the same number of credits in a connector as its x402 price (src/pricing_catalog.py):
| Product | Credits | USDC (x402) |
|---|---|---|
| Core crypto: VWAP, bid/ask, state price, 30m and 24h VWAP | 2 | $0.002 |
| Extended crypto: the same routes for long-tail pairs | 4 | $0.004 |
| FX and metals | 5 | $0.005 |
| Tokenized equities | 8 | $0.008 |
| Pre-trade sanity check | 100 | $0.10 |
| Market brief, price receipt, monitor evaluation | 250 | $0.25 |
| Token quality, state divergence | 500 | $0.50 |
| Macro snapshot, Solana token brief | 1,000 | $1.00 |
| Trader alpha pack | 2,500 | $2.50 |
The Anthropic-safe MCP surface is mounted at /anthropic/mcp/ and exposes read-only tools only (the Cursor and OpenAI connectors expose the same set):

The allowance is 30,000 credits per verified identity per calendar month (UTC), set by FREE_TIER_MONTHLY_CREDITS and shared by the Claude, Cursor, and OpenAI connectors. The legacy ANTHROPIC_DAILY_CREDITS, CURSOR_DAILY_CREDITS, and OPENAI_DAILY_CREDITS variables are ignored; per-user entitlement overrides for subscribers still apply.
For local beta testing, set ANTHROPIC_ENABLE_BETA_TOKENS=true and ANTHROPIC_BETA_TOKENS to a JSON object mapping random bearer tokens to user ids. For public Claude custom connectors, set ANTHROPIC_AUTH_PROVIDER=clerk, keep ANTHROPIC_ENABLE_BETA_TOKENS=false, and configure the Clerk env vars in .env.example. The Claude OAuth metadata endpoints are served at /.well-known/oauth-protected-resource/anthropic/mcp/ and /.well-known/oauth-authorization-server/anthropic/mcp.
For builders who want the full tool surface inside a local MCP client, this repo also contains the advanced local MCP server in src/mcp_server.py.
That mode is intended for direct builder integrations and requires local credentials.
Use GET /v1/coverage for current source-backed counts and qualification boundaries. The response separates enabled live discovery namespaces, decision-grade canonical RWA identities, and research/manual-verification coverage. Namespace and venue-row counts overlap and must not be summed as a unique-instrument total.
