Give Claude Desktop live crypto market data — prices, funding, open interest, liquidations, market regimes, Fear & Greed, dealer gamma and whale activity — as native MCP tools.
Two parts: the Agent Skill (knowledge — installed as a capability zip) and the MCP server (live tools). The MCP server connects over remote HTTP with a one-click browser sign-in — no key, nothing to install — or, for a headless or pinned-key setup, via the cryptodataapi-mcp stdio bridge in claude_desktop_config.json (needs Node.js).
~/Library/Application Support/Claude/claude_desktop_config.json · %APPDATA%\Claude\claude_desktop_config.json
Skills · Settings → Capabilities (zip upload)
Agent docs →
Download dist/cryptodataapi-skill.zip from the skills repo, then in Claude Desktop open Settings → Capabilities and upload it. Claude will consult the skill automatically on crypto-data tasks. See the Agent Skill page for what's inside.
Recommended — browser login. Add the cryptodataapi server with just its remote URL and no key — either paste the block below into your config file, or use Settings → Connectors → Add custom connector with the URL https://cryptodataapi.com/mcp. On the first tool call Claude Desktop opens a browser, you sign in at cryptodataapi.com and click Authorize, and you're connected — nothing pasted, no secret in your config. New here? Signing in creates a free-tier account automatically.
Advanced — bring your own key (stdio bridge). For a headless setup or to pin a specific key, use the cryptodataapi-mcp stdio bridge (needs Node.js; it runs via npx). Open your config file — ~/Library/Application Support/Claude/claude_desktop_config.json on macOS, %APPDATA%\Claude\claude_desktop_config.json on Windows, or Settings → Developer → Edit Config — add the block, and replace cdk_live_YOUR_KEY with your key (free one at cryptodataapi.com/login). The key stays in the config's env on your machine — never paste it into an AI chat.
Save and fully restart Claude Desktop.

After restarting, the tools appear under the MCP/tools indicator in the message box. Ask for a market read — see the example prompts below.
“Give me a one-call market snapshot: health score, regime, and Fear & Greed.”
“Compare BTC and ETH funding rates and tell me which side is crowded.”
“What's open interest doing across exchanges for BTC over the last 30 days?”
“Which coins are flashing the highest liquidation risk right now?”
“Is the market in a risk-on or risk-off regime today?”
No. The skill is free and the Free API tier (no card) covers the whole market-wide picture. Per-coin quant, gamma and whale signals need Pro.
In the env block of claude_desktop_config.json on your machine. The bridge reads CRYPTODATA_API_KEY and sends it as X-API-Key to our API on each call.
Almost always Node.js: npx must be on your PATH. Confirm with node -v, then fully quit and reopen Claude Desktop (a window reload isn't enough). Check Settings → Developer for the server's error log. If tools 401, fix the key in the env block.
