Common questions

Is Cryptoetf safe?

It passed 0 of 1 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?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.12) reached the registry 22 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?

CryptoETF MCP — spot crypto ETF flows for AI agents

The Model Context Protocol surface of cryptoetf.today: daily net flows for every US-listed spot crypto ETF complex and every fund in it, fund AUM, the CEFI sentiment index and live coin prices — for Claude, Cursor, Codex, Gemini CLI and any other MCP-capable agent.

Sixteen assets: BTC, ETH, SOL, XRP, HYPE, DOGE, LINK, AVAX, HBAR, LTC, BNB, DOT, SUI, NEAR, TRX, ZEC. Flow figures are net USD millions, sourced from the issuers' own daily reports; for the eleven smaller complexes there is no market-wide aggregator, so the numbers are computed from each issuer's fund pages.

You probably don't need to install anything. The server is hosted, and every client that speaks remote MCP can reach it directly:

https://mcp.cryptoetf.today/api/mcp     Streamable HTTP · JSON-RPC 2.0

No API key, no account — the endpoint is open.

Setup per client

Claude Code — one command, no restart:

claude mcp add --transport http cryptoetf https://mcp.cryptoetf.today/api/mcp

Cursor — .cursor/mcp.json (project) or ~/.cursor/mcp.json (global):

"mcpServers": { "cryptoetf": { "url": "https://mcp.cryptoetf.today/api/mcp" } } }

Claude Desktop and other stdio-only clients — this package is the bridge. claude_desktop_config.json, then restart the app fully:

"mcpServers": { "cryptoetf": { "command": "npx", "args": ["-y", "@zerosix-studio/cryptoetf-mcp"] } } }

Nothing to install by hand: npx fetches the package on first run. It has zero dependencies and simply forwards JSON-RPC between stdin/stdout and the hosted endpoint.

Tools

Tool	What it returns
`get_flows_summary`	Latest-day net flow for all 16 assets, with the date each figure belongs to
`get_asset_flows`	Daily net flow history for one asset over the last 30 days
`get_fund_flows`	The same 30 days for one asset, fund by fund (IBIT, FBTC, ETHA…), with ticker and issuer
`get_funds`	Fund directory: issuer, fee, listing date, current net assets (AUM) and coins held
`get_weekly_analytics`	7-day totals per asset: net flow, average day, positive/negative day counts
`get_cefi_index`	Composite CEFI index (0–100, 50 = zero net flow) with its flow, trend and breadth components
`get_prices`	Spot price and 24h change for every tracked asset

History reaches back 30 days, in the tools and in the REST API alike. Longer history is on cryptoetf.today.

Ask it things like

"What are today's crypto ETF flows?"
"Compare BTC and ETH ETF flows over the past month"
"Which asset had the strongest week of inflows?"
"Is the CEFI index bullish right now?"

Configuration

Variable	Default	Purpose
`CRYPTOETF_MCP_URL`	`https://mcp.cryptoetf.today/api/mcp`	Point the bridge at another endpoint
`CRYPTOETF_API_KEY`	—	Sent as `Authorization: Bearer …` when set; the public endpoint does not need it

Requires Node.js 18 or newer.

Data and limits

Flow data is updated every business day as issuers publish. Figures are informational — this is market data, not investment advice.

Privacy Policy

What is collected. The bridge forwards your JSON-RPC requests to https://mcp.cryptoetf.today/api/mcp and returns the responses. The only request data that leaves your machine is the tool name and its arguments (an asset ticker, at most). Conversation content, files and credentials are never read or transmitted.

How it is used and stored. The server logs the standard request metadata of any web service — IP address, timestamp, endpoint — and keeps a per-IP counter in Redis to enforce the 60 requests/minute rate limit. Logs are retained for 30 days and are used only to operate and protect the service.

Third-party sharing. None. Request data is not sold, shared or passed to any third party. The service is operated by us and calls only our own API.

Retention. Rate-limit counters expire within a minute; request logs within 30 days. No user accounts and no personal profiles exist — the endpoint is open and unauthenticated.

Releasing

Bump the version in package.json, then tag the commit:

git tag v1.0.4 && git push --tags

The Publish to npm workflow runs the bridge against the live server, skips the publish if that version is already in the registry, and otherwise pushes it with provenance — the npm page then links back to the exact workflow run and commit the tarball was built from.
