A confident tone is not yet proof
Ver-IF-MCP asks several AI models the same question at once, with your own OpenRouter key. Your assistant compares the answers, and every divergence raises an alarm.
Works in Claude Code, Codex, Gemini CLI, Cursor, ChatGPT, claude.ai and other tools with MCP.
- 3, 6 or unlimited
- models per question
- Streaming
- answers arrive as they are written
- No content stored
- logs only with your consent

01MISSION
Arbitration instead of trust in a single model
Every AI model has its own biases and gaps in knowledge. It gives an invented answer in the same confident tone as a true one, so the answer alone does not give it away.
Ver-IF-MCP puts the same question to several independent models. Claims they agree on build trust. Claims they disagree on are a signal to look for the truth, before the error reaches your code, report or decision.
Our mission is that no AI answer moves on unchecked.
- 01
Independent models
You choose models from different vendors. Each answers on its own, in the same layout.
- 02
Divergence is an alarm
Conflicting claims are not averaged away. You get them named, together with the model that made them.
- 03
Research settles it
After an alarm your assistant checks sources on the web or asks again with a reworded question.
02HOW IT WORKS
From question to alarm
01 / 04The question goes out in parallelTo every model in your pool, with your own OpenRouter key.
02 / 04Answers stream inAnswer, key claims and confidence. The same layout for every model.
03 / 04Your assistant compares claimsIt sorts them into agreed, divergent and made by one model only.
04 / 04Divergence raises an alarmYour assistant checks sources and says plainly what holds and what does not.
03REPORT
Your assistant gets the full report
The result goes to your assistant, not to our database. It has it at hand when you ask where an answer came from.
- Every model with its name, status, response time and cost
- Answer, key claims, confidence and uncertainties
- Comparison protocol: agreed, divergent, single and the alarm

05CONNECT
Connect Ver-IF in your tool
There is one server address. On first use your tool opens the browser: you sign in, paste your OpenRouter key and approve the connection.
MCP server address
https://ver-if-mcp.hexart.io/mcpAdd the server in a terminal, then type /mcp in Claude Code and choose to authenticate.
claude mcp add --transport http ver-if https://ver-if-mcp.hexart.io/mcpAdd the server and sign in. Codex stops tools after 60 seconds by default, so raise the limit or use verify_start.
# ~/.codex/config.toml
[mcp_servers.ver_if]
url = "https://ver-if-mcp.hexart.io/mcp"
tool_timeout_sec = 300
# terminal
codex mcp login ver_ifAdd the server to ~/.gemini/settings.json, then type /mcp auth ver-if in Gemini CLI.
{
"mcpServers": {
"ver-if": { "httpUrl": "https://ver-if-mcp.hexart.io/mcp", "timeout": 600000 }
}
}Add the server to ~/.cursor/mcp.json. Cursor asks you to sign in by itself.
{
"mcpServers": {
"ver-if": { "url": "https://ver-if-mcp.hexart.io/mcp" }
}
}Add the server to .vscode/mcp.json or your user configuration. Copilot agent mode asks you to sign in by itself.
{
"servers": {
"ver-if": { "type": "http", "url": "https://ver-if-mcp.hexart.io/mcp" }
}
}In connector settings add a custom MCP connector with this address. You sign in and paste your OpenRouter key in the consent window.
https://ver-if-mcp.hexart.io/mcpYour tool only supports local stdio servers? Run the mcp-remote bridge. It signs you in through the browser and forwards traffic to the server.
{
"mcpServers": {
"ver-if": {
"command": "npx",
"args": ["-y", "mcp-remote@0.14.3", "https://ver-if-mcp.hexart.io/mcp"]
}
}
}Key in a header instead of the connection
Want the key to stay out of our database, even encrypted? Skip it on the consent page. Send the X-OpenRouter-Key header from an environment variable instead. Example for Claude Code:
claude mcp add --transport http ver-if https://ver-if-mcp.hexart.io/mcp \
--header 'X-OpenRouter-Key: ${VERIF_OPENROUTER_KEY}'
06PRIVACY
Your questions and your key stay yours
We store
- Your e-mail and password hash, so sign in and password recovery work
- Your plan and the list of chosen models
- Hashes of connection tokens and your encrypted OpenRouter key
We never store
- Questions and model answers. Answers live in memory only, at most 10 minutes after a job ends. The exception: diagnostic logs, if you switch them on in the panel (encrypted, 30 days)
- Your OpenRouter key in plain form. Only the connection token held by your tool can decrypt it
- Logs with request content or headers
Check the next answer before you use it
An account takes a minute. You give your OpenRouter key on the first connection.
