Wire live crypto market data into your OpenClaw agent — prices, cross-exchange funding and open interest, liquidations, market regimes, Fear & Greed, dealer gamma and whale activity — so it can answer market questions from Discord, Slack, Telegram or any channel you've connected.
OpenClaw discovers tools through the Model Context Protocol and teaches behavior through skills (SKILL.md files). So the setup mirrors our two-part model: the MCP server provides the live tools, and the CryptoDataAPI skill provides the knowledge — added to your agent's skills list.
OpenClaw config → mcp.servers
Agent docs →
OpenClaw manages MCP servers under mcp.servers in its config, via the openclaw mcp commands. Add the remote server with your key on an X-API-Key header. The add command accepts HTTP flags such as --url, --transport and --header.
The resulting mcp.servers block looks like the JSON below. (Transport naming can vary slightly by OpenClaw version — if --transport is rejected, check openclaw mcp add --help for the exact value it expects for streamable HTTP.)
openclaw mcp add cryptodataapi \ --transport http \ --url https://cryptodataapi.com/mcp \ --header "X-API-Key: cdk_live_YOUR_KEY"
{
"mcp": {
"servers": {
"cryptodataapi": {
"url": "https://cryptodataapi.com/mcp",
"transport": "streamable-http",
"headers": { "X-API-Key": "cdk_live_YOUR_KEY" }
}
}
}
}
OpenClaw skills are SKILL.md directories the agent loads on demand. Clone our skills repo and place the cryptodataapi skill into your OpenClaw skills directory, then add it to the agent's skills list (a per-agent list replaces the defaults, so include every skill you want that agent to have).
Consult OpenClaw's skills docs for the exact skills path and per-agent allowlist syntax on your version.

Run openclaw mcp reload (or restart the gateway) so the new server and skill are picked up, then message your agent from any connected channel — see the example prompts below.
“Post a daily crypto market brief to this channel: regime, health score, Fear & Greed.”
“Alert me when the market regime flips from risk-off to risk-on.”
“What are BTC funding rates across exchanges right now, and is positioning crowded?”
“Which coins have the highest liquidation risk today?”
“Summarize open interest trends for the top 5 coins.”
No. OpenClaw is self-hosted and the skill is free. The Free API tier (no card) covers market health, regimes, Fear & Greed, macro, flows, coin profiles and full-universe Hyperliquid funding + open interest. Per-coin quant, gamma and whale signals need Pro.
In your OpenClaw config, on the cryptodataapi server's headers block (X-API-Key). Since OpenClaw is self-hosted, the key stays on your machine and is sent only to our API.
Run openclaw mcp status and openclaw mcp probe cryptodataapi to check the connection, then openclaw mcp reload. Confirm the server appears under mcp.servers. If tools return 401, fix the X-API-Key value or mint a free key via the server's create_free_api_key tool.
