Fermi
- Kromatic-Innovation/fermi
io.github.Kromatic-Innovation/fermi is an MCP server that returns calibrated probability distributions from natural-language questions via remote SSE.
About
io.github.Kromatic-Innovation/fermi is a remote MCP (SSE) and REST service that turns plain-language questions into calibrated probability distributions. developers validating ideas often get overconfident single numbers from chat models; Fermi is meant to structure uncertainty so you can compare scenarios when scoping an MVP, sizing a market, or sanity-checking forecasts. Connect from Claude Code, Cursor, or any MCP client that supports remote SSE endpoints—there is no bundled stdio package in the published server.json. Use it when you need ranges and likelihoods for planning conversations, not when you need live database queries or code execution. It complements spreadsheet models and analytics stacks rather than replacing them.
- Returns calibrated probability distributions from natural-language questions
- Exposed via MCP SSE remote at fermi.krobar.ai—no local npm/pypi package in the registry manifest
- REST and MCP dual access for scripts versus in-editor agents
- Version 1.0.0 in the MCP server schema
- Suited to decision support under uncertainty, not deterministic calculators

What it does
Turn fuzzy product or market questions into calibrated probability distributions before you commit scope or forecast outcomes.
Who is it for?
Best when you want probabilistic framing during validation and planning without building a custom stats model.
Skip if: Skip if you need audited historical data pipelines, ledger-grade finance, or guaranteed factual lookups.
What you get
You get distribution-shaped answers your agent can cite while scoping, researching, or framing growth forecasts.
- Calibrated probability distribution output for a stated question
- Agent-ready structured response usable in scope or research notes
By the numbers

FAQ
Who is fermi for?
Founders and product developers who use MCP agents and want calibrated uncertainty on strategic questions.
When should I use fermi?
During idea research, validation scoping, or growth planning when a distribution is more useful than one headline number.
How do I add fermi to my agent?
Register the remote MCP SSE URL https://fermi.krobar.ai/mcp/sse/ in your client’s MCP config; REST is also available for non-MCP scripts per the project docs.
