A hosted MCP server — one URL, no key, no install — that gives your agent jev, the decision model from TypeSafe AI: fact-checking, verified research and typed decisions with calibrated probabilities instead of prose. Works with Muse, Claude and Cursor.

Install
Prerequisites: None — no account, no API key. One URL, no install. No GitHub account needed unless listed here. Install "jevbook MCP" for me. A hosted MCP server for fact-checking and fast, calibrated decisions — typed verdicts with probabilities. Repository: https://github.com/jevbook/jevbook-mcp 1. Clone the repo into a temporary folder (public HTTPS clone — no account needed) and look inside. Summarize it for me in one or two sentences. 2. Safety check: briefly review any scripts for anything suspicious (network calls to unexpected hosts, shell commands, credential harvesting). If you see a red flag, stop and tell me before going further. 3. This is a hosted MCP server — nothing to build. Connect it at https://jevbook.dev/mcp. Show me the exact MCP client config snippet (URL + transport) for my setup and where to put it. Don't start any server. 4. Verify without network calls: the endpoint URL responds (a simple check is fine). 5. Report: what you installed, where, and anything still left for me to do myself (or confirm there's nothing left). GitHub is optional: if I have a GitHub account or the gh CLI, you may use it (e.g. authenticated clone); otherwise public access is fine. Never require it unless it's in the prerequisites above. Rules: don't touch anything outside the temp folder and the install target. If anything looks off, stop and ask me.
