# Human Signal (HTTP / ChatGPT)

> The 5 MCP tools exposed over Streamable HTTP — paid panel studies: ask real people, retrieve results, manage studies.

Paid panel studies. Costs roughly \$1–\$5 per respondent. 5 tools.

<Note>
  This is the **Streamable HTTP surface** — what the ChatGPT connector (OAuth) exposes.
  It is intentionally limited to the Human Signal flow: no research CRUD, participant PII,
  or payment tools are served over an OAuth bearer. The full 29-tool research surface is
  stdio-only (`npx -y @userintuition-ai/mcp` with an API key) — see the
  [tool reference](/mcp-server/tools/studies). `list_studies` here is the Human Signal
  variant; the stdio tool of the same name lists research studies.

## How User Intuition handles this

Human Signal studies recruit from User Intuition's own panel and run AI-moderated —
no panel contracts, no scheduling. Pair with [`/platform/agentic-research/`](https://www.userintuition.ai/platform/agentic-research/)
for the full agent workflow.
