eidentic

Eidentic is the open-source TypeScript SDK for AI agents with self-improving memory and production fundamentals built in. Durable execution, enforced cost ceilings, multi-tenant isolation, GDPR erasure, and sandboxed tools — not bolted on. Apache-2.0. Runs on Node, Bun, Deno, and the edge.

Install

npm install eidentic ai @ai-sdk/anthropic
# or
pnpm add eidentic ai @ai-sdk/anthropic

Quickstart

import { Agent, AIModel, SqliteStore } from "eidentic";
import { anthropic } from "@ai-sdk/anthropic";

const agent = new Agent({
  id: "support",
  model: new AIModel(anthropic("claude-sonnet-4-5")),
  store: new SqliteStore("./eidentic.sqlite"),
});

for await (const ev of agent.query("What did we decide last week?", { sessionId: "u-42" })) {
  if (ev.type === "stream.delta") process.stdout.write(ev.delta.text);
  if (ev.type === "result") console.log("\nDone:", ev.subtype);
}

Next.js / serverless: use @eidentic/libsql (pure-JS, no native addon) instead of SqliteStore. See the Next.js quickstart.

What the umbrella package covers

The eidentic package re-exports the core stack so you get everything in one install:

| Included package | What it provides | |---|---| | @eidentic/core | Agent, createTool, ToolRegistry, strategies, guardrails, permissions | | @eidentic/types | Canonical protocol types and port interfaces | | @eidentic/model | AIModel, AIEmbedder, price tables, Ollama adapter | | @eidentic/sqlite | SqliteStore — durable store over better-sqlite3 (Node/Bun) | | @eidentic/convex | ConvexStore — Convex-backed store + temporal KG + vector + durable execution (reactive, TS-native) | | @eidentic/memory | Memory — four-tier recall, self-editing blocks, knowledge graph | | @eidentic/cli | eidentic dev / eidentic studio / eidentic init commands |

Optional adapters are separate packages — install only what you need:

| Package | Purpose | |---|---| | @eidentic/server | Hono HTTP server (streaming query, async runs, auth, rate-limiting) | | @eidentic/nextjs | Next.js App Router route helper (withEidentic) | | @eidentic/react | React hooks (useAgent, useEidenticStream, useWorkflowList) | | @eidentic/libsql | LibSQL / Turso store (edge-compatible, no native addon) | | @eidentic/postgres | PostgreSQL store adapter | | @eidentic/workflow | Durable workflow orchestration (steps, parallel, retry) | | @eidentic/mcp | MCP host + server with OAuth 2.1 | | @eidentic/a2a | A2A protocol interoperability | | @eidentic/skills | Skill substrate (SKILL.md + executable + self-evolution) | | @eidentic/eval | Eval harness with CI gate and trace promotion | | @eidentic/tools | File, bash, web search, and HTTP tools | | @eidentic/rag | Document ingestion and chunking (PDF / HTML / Markdown) | | @eidentic/lancedb | LanceDB vector store | | @eidentic/pgvector | pgvector (PostgreSQL) vector store | | @eidentic/qdrant | Qdrant vector store | | @eidentic/pinecone | Pinecone vector store | | @eidentic/e2b | E2B Firecracker sandbox adapter | | @eidentic/transformers | Local embedder / reranker (no API key) | | @eidentic/langfuse | Langfuse OTLP tracing | | @eidentic/studio | Local dev dashboard |

Three pillars

1. Memory that improves itself. Four-tier engine: lexical + semantic recall (RRF fusion), self-editing blocks, a temporal knowledge graph (facts with validity ranges; contradictions invalidate rather than accumulate), and sleep-time consolidation.

2. Production fundamentals built in. Durable checkpoint/resume with exactly-once tool dispatch, enforced cost ceilings per turn, built-in rate-limiting and quotas, OpenTelemetry GenAI spans, a structured audit-event stream (permission denials, quota/rate-limit rejections, auth failures, erasure), deny-by-default permissions, sandboxed code execution, secret isolation, and one-call GDPR erasure that fans out across every store.

3. Runs everywhere. Ports-and-adapters: swap the store, vector backend, embedder, or sandbox without touching agent code. Verified on Node, Bun, and Deno in CI.
