Bitculator MCP Server

What It Does

Bitculator MCP Server connects AI assistants like Claude, Cursor, ChatGPT and any MCP-compatible client to live cryptocurrency market data through a single Streamable HTTP endpoint. It exposes 19 read-only tools for current prices, price history, sentiment indicators (Fear & Greed, Altseason Index), global market snapshots, technical indicators and exchange data. Prices arrive as decimal strings, so no digits are lost to floating-point rounding.

Who It's For

Developers building AI agents and assistants that need reliable crypto market data: a conversational market assistant in Claude Desktop, live price checks in a Cursor workflow, or agents built with the OpenAI Agents SDK, LangChain, LlamaIndex, Mastra or Semantic Kernel. The server plugs in directly, with no custom wrapper needed.

Key Features & Capabilities

• 19 read-only tools, including get_prices, get_price_history, get_historical_price, get_global_market, get_global_history, get_fear_greed, get_altseason_index, get_coin_technicals, convert_currency, calculate_dca and get_top_movers
• Exact numbers: prices are averaged from 16 exchanges and sent as decimal strings, never floats
• Sentiment & global metrics: Fear & Greed for the market or a single coin, Altseason index, total market cap, 24h volume, top gainers and losers
• Works with any MCP client: Claude Desktop, Cursor, VS Code, ChatGPT (developer mode) and agent frameworks that speak Streamable HTTP
• Read-only by design: agents can quote and analyse the market, but never trade or touch wallets
• Plans: Free (2,500 tool calls a month, 2 keys), Starter ($9.99/month, 50,000 calls, 5 keys), Pro ($29.99/month, 250,000 calls, 10 keys)

Typical Workflows

A user asks their assistant for a morning market briefing; it calls get_global_market, get_fear_greed and get_top_movers and summarises the results. A crypto analysis agent can chain get_prices, get_coin_technicals and convert_currency for multi-step portfolio questions.

Integrations

One endpoint (https://bitculator.com/mcp) and an MCP key: create a key in the MCP console (the free tier needs no card), add the endpoint and key to your client's config, and the 19 tools appear as native functions. The key can be sent as Authorization: Bearer <key> or as X-API-Key: <key>. MCP tool calls count only against the MCP plan, separate from Bitculator's Data API and widget quotas.
