Bitculator MCP Server

Live and historical crypto market data for AI agents: prices, OHLCV history, sentiment indices, technical indicators, exchanges, liquidations and conversions, as 19 read-only tools.

It is a hosted, remote MCP server: there is nothing to install or run. Point any MCP client that supports remote servers over Streamable HTTP at the endpoint below and add your key.

Get a key

Create a key in the MCP console. The free MCP plan works, no card required. MCP keys are their own product: Data API keys and widget keys are rejected with 401 unauthenticated.

Keep the key out of shared files you commit: put it in your client's settings or an environment variable.

Connect

Claude Code

claude mcp add --transport http bitculator \

https://bitculator.com/mcp \ --header "Authorization: Bearer YOUR_API_KEY"

Cursor

This repository is also a Cursor plugin (.cursor-plugin/plugin.json): it asks for your MCP key once (stored by Cursor, never in this repo) and adds the server and the bitculator skill. Or configure it by hand in ~/.cursor/mcp.json:

{

"mcpServers": { "bitculator": { "url": "https://bitculator.com/mcp", "headers": { "Authorization": "Bearer YOUR_API_KEY" } } } }

VS Code (.vscode/mcp.json)

{

"servers": { "bitculator": { "type": "http", "url": "https://bitculator.com/mcp", "headers": { "Authorization": "Bearer YOUR_API_KEY" } } } }

Claude API (MCP connector)

curl https://api.anthropic.com/v1/messages \

-H "x-api-key: $ANTHROPIC_API_KEY" \ -H "anthropic-version: 2023-06-01" \ -H "anthropic-beta: mcp-client-2025-11-20" \ -d '{ "model": "claude-opus-4-8", "max_tokens": 1024, "mcp_servers": [{ "type": "url", "url": "https://bitculator.com/mcp", "name": "bitculator", "authorization_token": "YOUR_API_KEY" }], "tools": [{ "type": "mcp_toolset", "mcp_server_name": "bitculator" }], "messages": [{ "role": "user", "content": "How is the crypto market today?" }] }'

Smithery and other gateways

On Smithery, enter your MCP key in the connection form. Gateways that reserve the Authorization header for their own sign-in can send the same key as an X-API-Key header instead.
