Today is the operative word: we check California Bitcoin every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

bitcoin
get_bitcoin_evidence_pack
PAID 0.50 USD via Stripe MPP. Build a focused Bitcoin evidence package that separates verdict-eligible atomic claims from contextual material and reports source authority, exact-locator precision, conflicts, caveats, provenance, and temporal scope. Collect supporting, conflicting, and contextual evidence around one focused Bitcoin research question with explicit evidence-quality metadata.
get_bitcoin_topic
FREE. FREE, no account required. Retrieve one canonical Knowledge Atlas topic with sources, provenance and related concepts. Inspect a known canonical topic in depth before deciding whether paid evidence packaging is necessary.
search_bitcoin_knowledge
FREE. FREE, no account required. Search canonical Bitcoin Knowledge Atlas topics and related history to evaluate coverage on the caller's real question. Run the first no-cost evaluation when you need to see which maintained Bitcoin topics and evidence match a query.
answer
answer_bitcoin_question
FREE. FREE, no account required. Return a concise deterministic answer grounded in the maintained Knowledge Atlas. Use this as the default first evaluation on a real Bitcoin question. Evaluate California Bitcoin on the caller's actual question before paying for deeper research.
batch
batch_bitcoin_research
PAID 2.50 USD via Stripe MPP. Process up to 20 distinct Bitcoin claims, questions, or evidence requests in one deterministic research package while preserving per-item verdict and evidence-quality semantics. Process multiple distinct Bitcoin claims, questions, or evidence requests while retaining the evidence standard for each item.
build
build_bitcoin_timeline
PAID 0.50 USD via Stripe MPP. Build a query-specific historical Bitcoin research timeline that distinguishes event dates, source dates, effective dates, source-level support, exact locators, and maintained re-verification boundaries. Put maintained Bitcoin events in chronological order while preserving source and temporal semantics.
deep
deep_ground_bitcoin
PAID 1.00 USD via Stripe MPP. Produce a deeper deterministic Bitcoin research dossier across canonical topics, verdict-eligible atomic claims, contextual material, conflicting evidence, source hierarchy, exact-locator precision, temporal scope, history, and caveats. Ground a multi-topic Bitcoin research dossier while preserving what is proven, contextual, disputed, time-bounded, or insufficiently supported.
select
select_bitcoin_research_product
FREE. FREE, no account required. Select a research product and inspect its price, free evaluation path, and contract using an explicit task: verify, evidence, chronology, dossier, batch, or learn. Does not authorize payment. Choose the smallest appropriate research product after a free evaluation and before initiating any paid request.
verify
verify_bitcoin_claim
PAID 0.50 USD via Stripe MPP. Evaluate a Bitcoin proposition against verdict-eligible maintained atomic claims and return a conservative rich verdict with supporting, conflicting, contextual, provenance, precision, and temporal evidence metadata. Determine whether a specific Bitcoin proposition is supported, contradicted, mixed, only partially verifiable, or not supported by enough maintained evidence.

California Bitcoin — questions
Answers built from our own checks of this server.
What can California Bitcoin do?
It exposes 9 tools, read directly from the server on our last check. Among them: answer_bitcoin_question, batch_bitcoin_research, build_bitcoin_timeline, deep_ground_bitcoin, get_bitcoin_evidence_pack, get_bitcoin_topic and 3 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README.
How MCP servers expose tools in the first place →
Is California Bitcoin working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 93 of 93 checks got a reply (100.0%), average response time 255 ms. The bar chart above shows every period we have measured.
How do I connect California Bitcoin?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does California Bitcoin need an API key?
No. California Bitcoin completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 9 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is California Bitcoin?
It answers our handshake in 255 ms on average, which is faster than 59% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
