BCA Crypto Brain
The editorial ground truth for crypto LLM agents. An open, self-hostable Model Context Protocol server that gives Claude, ChatGPT, Perplexity, LangChain, Eliza, and Virtuals Protocol agents dated, cited, cross-referenced crypto intelligence — instead of hallucinated facts from pretraining.
Published as @blockchainacademics/mcp on npm. MIT licensed. One command to install.

What you get
- 99 typed tools across news, market data, on-chain analytics, sentiment, directories, fundamentals, events, dev infrastructure, portfolio, microstructure, regulatory, security, narrative, chains, memes, compute, and services.
- 6 proprietary indicator composites — Coverage Index, Narrative Pulse, Dev Activity, Sentiment Momentum, Regulatory Risk, Macro Exposure — scored daily across 500+ assets.
- 5 agent-backed generators —
due_diligence,tokenomics_model,summarize_whitepaper,translate_contract,monitor_keyword. Long-running jobs that spin off Groq-powered workers and stream back polished markdown. - Attribution envelope on every response — every tool call returns
{data, cite_url, as_of, source_hash}. Your agent never has to guess where a fact came from, and your users can always click through.
Why BCA over pretraining?
Pretraining is a frozen snapshot. BCA is live editorial: ~10 articles/day, 3,501+ archived pieces, entity graph with ~6,000 canonical crypto projects, tokens, people, and institutions — all reconciled to a single source of truth, all timestamped, all citable.
When an agent calls search_news("circle IPO"), it gets titles + summaries + cite_url links that resolve to published articles on blockchainacademics.com — each carrying UTM params so we attribute the agent caller correctly. No hallucinated dates, no made-up quotes, no stale pretraining.
