Gemini CLI HEY Research Lab Prompt/explain_project_evidence

How to: Gemini CLI HEY Research Lab explain_project_evidence

client:Gemini CLI transport:streamable-http prompt:explain_project_evidence

Add HEY Research Lab to Gemini CLI

  1. 01

    Open ~/.gemini/settings.json and merge this in. Keep any servers already there. 

{
  "mcpServers": {
    "hey-research": {
      "httpUrl": "https://heyresearch.xyz/mcp"
    }
  }
}
  1. 02

    Save the file and restart Gemini CLI.

  2. 03

    explain_project_evidence is surfaced in the client's prompt or command menu. Unlike a tool, you invoke it deliberately — Gemini CLI will not call it for you.

  3. 04

    If it does not appear, check that HEY Research Lab is connected and that you are looking at its prompts rather than its tools.

Gemini expands $VAR and ${VAR} inside env values, so a secret can live in your shell rather than this file. Gemini CLI docs

Set these first

HEY Research Lab will not start until these are set, so it never reaches Gemini CLI.

  • HEY_API_KEY
  • HEY_MCP_PROFILE

Same prompt, other clients

Read from the server itself, by connecting to it and calling prompts/list on 5 October 2026. A listing does not declare its prompts, so asking is the only way to know them, and this is what the server actually offers rather than what its listing claims. Names only are stored; connect the server for each prompt's arguments.
