Thrindex - Thrindex docs

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.

SDK

Python and TypeScript clients, plus drop-in integrations for OpenAI, Anthropic, LangChain, and LlamaIndex.

API

REST endpoints for store, search, list, get, and delete — scopes, errors, and full request reference.

MCP

Connect Claude, Cursor, GitHub Copilot, and other MCP clients to persistent memory in minutes.

Get started

Quickstart

Store and search your first memory in under five minutes.

Dashboard

API keys, usage, and organization settings at app.thrindex.com.

How it works

Memory model, write pipeline, scoping, and search ranking.

Authentication

API keys, scopes, and how org isolation is enforced.

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

Create an account

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.

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.
