The reusable backend for building, persisting, and operating AI agents — built on AI SDK v7, designed to embed in your stack and grow with you.
Latch is the connective tissue you'd otherwise write by hand around the AI SDK: message persistence, multi-tenant context, tools & MCP, a credential vault, durability (resume-after-crash), scheduling, usage/cost tracking, and human-in-the-loop approvals — as , not an all-or-nothing framework.
Latch MCP host — connect to MCP servers as tools, with a per-tenant SSRF allowlist and vault-brokered auth.
It starts as thin ergonomics over the AI SDK (define an agent, stream it — runs on any serverless backend, zero infrastructure). When the product needs more, you turn on a database, then durability, then connections — each step additive, never a rewrite or a data migration. A weekend prototype and a multi-tenant production platform run the same core.
Why it exists, in one line: stop rebuilding the same agent backend for every product. See
PHILOSOPHY.mdfor the why and the docs for the how.
defineAgent / defineContext: typed, lazy, engine-agnostic config over ToolLoopAgent. Your tenant shape flows into agents, tools, and hooks with no any.chats / messages / runs / usage via a single StorageAdapter (Drizzle: SQLite & Postgres today, same contract). AppMessage is a typed UIMessage, so all the stock SDK stream/persistence helpers work unchanged.runtime.cron() fires due schedules and reaps-and-resumes stalled runs; drive it from an in-process interval loop or a serverless POST /cron/run route.awaiting_input), the decision round-trips as message state, then continues. No suspension machinery.writer for streaming structured/transient UI artifacts (status, citations, markers), available in the turn and to tools, with full user/run context.visibility, sendToModel). Internal context reaches the model without leaking to the user.Pricing seam.Principal / ContextResolver seam; tenant isolation enforced at the storage layer (IDOR-proof by default).MCP, vault, approvals, scheduling, and rate-limiting are independent opt-ins at any tier.

const { app } = await createLatchHonoApp({
storage: createSqliteAdapter(drizzle(client, { schema }), { owner: (p) => [p.orgId] }),
// BYO auth: request → your Principal, null → 401. Replace the header lookup
// with your session — trusting a caller-supplied header is for local demos only.
resolveContext: async (req) => {
const org = req.headers.get("x-org");
return org ? { orgId: org } : null;
},
// Agents pick their model from the models.dev catalog (whatever you have keys for).
agents: (models) => ({
assistant: defineAgent({
model: models.modelFor("claude-sonnet-4-6"),
instructions: "You are a concise, helpful assistant.",
defaultTools: true, // web_fetch, askUser, schedule tools
}),
}),
});
serve({ fetch: app.fetch, port: 8787 });
That's the whole backend: durability (resume-after-crash), an in-process cron (or POST /cron/run on serverless), pricing + reasoning + prompt-caching hooks from the catalog, the harness tools, and the HTTP surface. App-level options (models, principalKey, cronIntervalMs) sit on the config itself; every runtime and handler default is overridable via runtime / handler. Prefer to mount into your own framework? const { handler, runtime, models, stop } = await createLatchApp({...}) gives you the bare Web handler; createLatchHandler() / createRuntime() are still there when you want to wire pieces yourself.

A runnable, durable server with the reaper + MCP-OAuth routes lives in apps/example/src/serve.ts.
Install the Latch skill so Claude Code, Cursor, Codex and other agents build with Latch the way it's meant to be used: recipes for the common tasks, the rules that break quietly, and the docs for your version.

createRuntime); everything (routes, cron, tests) calls the runtime, never the seams directly. Stateless and serverless-safe — all per-run state lives in the DB. Operations: handleChat, loadHistory, resume, sweep, tick, applyApproval.AppMessage — the stored unit and source of truth: a typed UIMessage<AppMetadata, …>. Two axes on the metadata (visibility, sendToModel) drive the client and model projections (toClientMessages / toModelMessages). Execution facts (usage, cost, model, finishReason) ride in metadata — no separate "steps" table.StorageAdapter, durability engine, Scheduler, Vault/SecretStore, MCP host, Pricing, ContextResolver. Sensible defaults, swappable without touching agent code.tick()/sweep() reclaims dead ones; fencing tokens stop a zombie worker from corrupting reassigned state.@intentface/latch-core runtime, AppMessage + projections, durability, vault,

Working today (exercised by 17 smoke suites, both SQLite & Postgres): agents & context, persistence, streaming + Hono routes, tools, MCP host + OAuth, vault, durability (lease/heartbeat/reaper/fencing/resume/checkpoint), scheduler, tool approvals, writer/data parts, message projections, usage & cost.
Working today also includes memory (@intentface/latch-memory): agents that declare memory get a compiled index injected per turn, memory_search/memory_save tools, and background extraction + consolidation via the cron sweep. Scopes: agent-user | agent-org | user. Caveat: on an org-shared connection, per-user separation is a folder convention — anyone with workspace access can read the _memory/** files.
Also working: subagents (spawn_agent, each in its own persisted thread; approvals surface to the parent), compaction (runtime.compactChat, projection-only — the record is never rewritten), a sandbox seam with the harness tools, code execution in a QuickJS engine, OpenAPI tools, per org/user/agent limits, agents as data, and the models.dev catalog for pricing, reasoning and prompt caching.
Not built: files & attachments as a seam (FileStore), MCP elicitation, a CLI, and observability beyond OpenTelemetry tracing (latch-otel).
