What it can do

Tool names and descriptions exactly as the server reported them on Nov 8, 2026. The maker wrote them, not us; we show them as plain text.

search_pairs
Discover supported crypto, equity, FX, and metal symbols before using the paid HTTP API. Returns up to 50 catalog matches with asset class, available services, and pricing tier; it is free, read-only, and never returns live prices or starts payment.
list_instruments
List the supported instruments for one Blocksize service. This is free, read-only catalog metadata; it does not fetch live prices, create accounts, or start x402 payment.
get_pricing_info
Inspect current direct x402 per-call prices, authenticated connector starter-credit costs, supported USDC settlement networks, and the account-plan contact path. This is free read-only metadata; it does not initiate payment.
get_product_catalog
Inspect Blocksize raw data, supported equity ticker bid/ask, and premium agent-native workflow products, including starter-credit positioning, credit costs, suggested paid prices, endpoint templates, and upgrade path. This is free and read-only.
recommend_account_plan
Recommend a sales-assisted Blocksize account plan from expected live-call volume, team size, recurring use, and SLA needs. This is free and does not collect contact details, create an entitlement, or start a purchase.
get_workflow_endpoint
Build the exact paid HTTP endpoint, method, starter-credit cost, and example body for a premium Blocksize workflow. This is free and read-only; it does not fetch live data, charge credits, or start x402.
get_market_data_endpoint
Build the exact x402-protected HTTP URL for one live market-data request. Returns method, URL, service notes, pricing docs, and next steps; it is read-only and does not fetch prices, charge a wallet, or submit payment.
search
Search Blocksize documentation and catalog metadata by keyword. This free read-only search returns document and instrument ids for fetch; it does not return live prices or start payment.
fetch
Fetch one document or instrument guide returned by search. This is free, read-only content retrieval with no account, credential, payment, or live-price side effects.

Common questions

Is Blocksize Agentic Market Intelligence safe?

It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.6.24) reached the registry 33 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

Indexing checklist:

Submit https://mcp.blocksize.info/sitemap.xml in Google Search Console and Bing Webmaster Tools.
Request indexing for the homepage, data package catalog, and every canonical intent page above.
Use the MCP manifest, server.json, llms.txt, OpenAPI JSON, and data-packages.json as the canonical machine-readable citations in marketplaces, docs, and repo descriptions.
Use category-hubs.json for dated coverage states, rights boundaries, methodology, and citation instructions. Cataloged, candidate, and production-promoted coverage are intentionally separate states.

RWA claims boundary:

Blocksize already provides broad production coverage across its live market-data packages.
Separately, the reconciled 2026-07-30 RWA research snapshot contains 1,169 RWA.xyz source-asset rows and 3,438 token-listing rows (3,435 unique contract identities). Its lossless cross-venue matrix contains 2,139 canonical assets and 5,161 venue instruments; these are catalog and identity grains, not production-feed counts.
Candidate expansion lanes are not additional production feeds until their promotion gates pass.
Zero newly sourced third-party or onchain additions have completed the full RWA expansion-workflow promotion process. This figure does not describe or reduce existing Blocksize production coverage.
Hash-linked provenance receipts are not described as cryptographically signed unless a response includes a signature envelope with an algorithm, key identifier, digest, and signature.

Product Shape

1. Public remote MCP discovery server

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_pairs
list_instruments
get_pricing_info
get_product_catalog
recommend_account_plan
get_workflow_endpoint
get_market_data_endpoint
search
fetch

This public surface does not execute paid live market data calls directly.

2. Paid HTTP market data API

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/batch

Free discovery endpoints:

GET /v1/coverage
GET /v1/search
GET /v1/instruments/{service}
GET /v1/samples/market-data?service=vwap&symbol=BTCUSD for a clearly synthetic value preview and attributed paid handoff
GET /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:

signed x402 v2 payment per request via PAYMENT-SIGNATURE
starter credit drawdown through an authenticated Claude, Cursor, or OpenAI connector principal

New 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

3. Anthropic-safe MCP beta

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):

search_pairs
list_instruments
get_credit_balance
get_vwap
get_bid_ask
get_state_price
get_vwap_30m
get_vwap_24h
get_fx_rate
get_metal_price
get_market_brief
run_pre_trade_check
create_price_receipt
get_macro_snapshot
get_token_quality
get_state_divergence
get_solana_token_brief
get_trader_alpha_pack

Live market data tools use server-side free-tier credits keyed to authenticated user identity. 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.

4. Advanced local 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.

Coverage

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.

Local Development
