# Thrindex

> The memory OS for AI agents.

A cognition engine that ranks, compresses, and evolves agent memory across any model, any framework, at any scale.

Thrindex gives your agents persistent memory: store facts after each interaction, search for relevant context before every model call, and let the platform handle extraction, deduplication, importance scoring, and retrieval.

## How it fits your stack

**SDK / API** — your agent backend calls Thrindex directly:

```
Your agent backend
  │
  ├── POST /v1/memories         ← store a fact after a conversation turn
  │
  └── POST /v1/memories/search  ← retrieve ranked context before each LLM call
```

**MCP** — your AI client calls Thrindex as a remote tool server:

```
Claude Desktop / Cursor / Copilot / …
  │
  └── POST https://api.thrindex.com/mcp   ← JSON-RPC (store_memory, search_memories, …)
```

Both paths use the same memory store, scoping, and cognition pipeline. Writes return `202 Accepted` and are processed asynchronously; searches return `200 OK` with ranked results in a single request.

## What you need

<Steps>
  <Step title="Create an account">
    Sign up at [app.thrindex.com](https://app.thrindex.com) and create an organization.
  </Step>

  <Step title="Generate an API key">
    In the dashboard, go to **API Keys → New key**. For MCP, include `memory:write`, `memory:read`, and `memory:delete`. For API-only use, select the scopes your agent needs. Copy the key when shown — it cannot be retrieved again.
  </Step>

  <Step title="Choose how to integrate">
    Pick **SDK** or **API** to wire memory into your backend, or **MCP** to connect an AI client — then follow the linked guide.
  </Step>
