About STEMPA
STEMPA is a hosted remote MCP server for people who want to establish a consistent brief for AI work. It elicits missing details and seals the resulting version with a signed receipt.
Key features
- 01Finds gaps in an AI's understanding
- 02Asks up to five questions at a time
- 03Freezes answers into a brief
- 04Creates a fingerprint and signed receipt
- 05Versions changed briefs
Use cases
- 01Aligning AI work around an agreed project brief
- 02Reusing the same sealed brief across connected AI services
MCP support
STEMPA exposes tools for mapping a job, eliciting and answering gaps, freezing briefs, and reading them back. MCP clients connect to its remote server using OAuth 2.1.
Configuration
Remote servers need no local install. Pick your client, then copy the config or install in one click.

Brief your AI once. Seal it.
STEMPA is a remote MCP server. Your AI first lists what it already knows about a job, then asks you only about the gaps: up to five questions at a time, each with a suggested answer. You answer once, and STEMPA seals your answers into one brief with a signed receipt. Change a word and it becomes a new version.
Works with Claude, ChatGPT and Grok.
- Server address:
https://stempa.kragos.app/mcp - Transport: Streamable HTTP
- Sign-in: OAuth 2.1 with dynamic client registration and PKCE. There is no key to paste.
- Website: https://stempa.kragos.app
- Official MCP Registry name:
app.kragos/stempa(seeserver.json)
This repository is documentation only. STEMPA is a hosted service; there is nothing to install or run locally.
Connect
STEMPA works with Claude, ChatGPT and Grok; step-by-step instructions for each are in CONNECT.md. In short: paste https://stempa.kragos.app/mcp into your AI's connectors, and sign in to STEMPA when asked.
Any other MCP client that supports remote servers with OAuth connects the same way: add a remote server with the address https://stempa.kragos.app/mcp. The client finds the sign-in itself; there is no key to paste. In a client that reads an mcp.json file, the entry looks like this:
{
"servers": {
"stempa": {
"type": "http",
"url": "https://stempa.kragos.app/mcp"
}
}
}
The first sign-in creates a free STEMPA account.
Use it
- Say to your AI: "Grill me on [your idea]."
- Your AI lists what it already knows, then asks only about the gaps: up to five questions at a time, each with a suggested answer. Accept the suggestion, pick an option, or type your own.
- When the gaps are closed, your AI freezes the brief.
- Open your account at https://stempa.kragos.app and press Seal. The brief gets a fingerprint and a signed receipt.
- Later, in any AI you connect, ask it to read your sealed brief. It reads the same sealed version.
Tools
grill_start, grill_map, grill_gaps, grill_answer, grill_freeze, and tools that read your briefs back.
How a brief is sealed
- Connect. Add STEMPA to the AI you already use.
- Answer. Your AI lists what it already knows, then asks only about the gaps. Pick an option, accept the suggestion, or type your own.
- Seal. Your AI freezes the brief; you seal it with one press in your STEMPA account. The sealed brief gets a fingerprint and a receipt with post-quantum signatures. Anyone you share a receipt with can check it on the receipt page.
A sealed brief is a record of the scope you agreed.

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
