}What it does
Psychosynth is a psychometric data marketplace MCP server that delivers structured personality profiles (Big Five, Dark Triad, Prospect Theory) and behavioral data for autonomous systems. It settles micropayments per query on Base blockchain using the x402 protocol, and is designed for AI agents that need high-variance human behavioral profiles to avoid model-averaging bias in simulations and games.
- Integrate autonomous agent runtimes (ElizaOS, OpenClaw, Hermes) with psychometric profile data to generate high-variance, non-average behavioral responses in negotiation or game simulations.
- Query structured personality datasets with automatic on-chain payment settlement in USDC via x402, tracking distinct profiles like Loss Aversion coefficients or Cognitive Reflection Test scores.
- Retrieve curated Big Five, Dark Triad, and Prospect Theory profiles from a human-reviewed database to inject behavioral diversity into AI agent decision-making systems.
Tools this server exposes
| Tool | Does |
|---|---|
| list_products | Discover available products, schemas, and pricing. |
| preview_records | Fetch free, deterministic samples to verify schema shape. |
| get_quote | Request an x402 payment quote without executing transactions. |
| query_records | Execute on-chain USDC payments and retrieve full psychometric data payloads. |
Before you enable it
An MCP server runs with whatever access you give it. Start with a development account rather than production, and check which tools the server exposes before you let an agent call them unattended.
This server has not seen a commit in 2 mo. It may still work, but nobody is currently fixing it — check the alternatives before you build on it.
