The missing identity & memory sidecar for LLM engines and multi-agent frameworks.
Attach Gateway sits between your apps and model servers to solve two gaps every AI stack has: who is this request from and what context should it carry. It adds SSO authentication, agent-to-agent hand-off, and pluggable memory—without changing your model server.
Most LLM engines (local or cloud) ship with no authentication by default.
Multi-agent protocols assume a bearer token exists, but don't say how to issue or verify it.
Teams end up with ad-hoc reverse proxies, leaked ports, and copy-pasted JWT code everywhere.
Attach Gateway is a resource server for AI: it validates identity, stamps headers for downstream engines, and mediates reads/writes to your memory store.
Run it next to any HTTP model API and get secure, shareable context in minutes.
Client exchanges for token (SSO/service account)
Attach validates and adds identity headers
Request forwarded to model server with context
Engineered like a seat-belt for LLM stacks—always on, invisible until you need it, replaceable without ripping out the car.
Runs offline on your laptop, VM, or container. Cloud hosting is a choice, not a requirement.
Every downstream endpoint is untrusted until Attach stamps verified identity headers.
Context lives in a pluggable storage bus you control. Hot-swap backends without code changes.
Works with OIDC/DID, agent-to-agent hand-off, and emerging AI protocols.
JWT is the state. Tracing and metrics are built-in for real-time auditing.
No prompt bodies logged by default. Memory writes require signed calls. We never train on your data.
Support for multiple identity providers, configurable via environment variables.
Hot-swappable memory backends for context storage and retrieval.
Comprehensive observability and token usage tracking out of the box.
Everything configurable via .env variables. No complex YAML files or UI configuration needed.
Local SSO or pre-issued tokens plus local memory. No internet required.
Attach mediates access to your data stores. We never see or store your content.
Every request has a trace ID. Built-in metrics for identity flows and memory access.
No. You own storage; Attach mediates access. We never train on your data or store prompts.
Yes—local SSO or pre-issued tokens plus local memory. Perfect for air-gapped environments.
It's identity + memory semantics purpose-built for LLMs and agents, not generic HTTP routing.
Stateless design scales horizontally. JWT validation is fast, memory lookups are optional and async.
We're building the infrastructure layer that AI applications actually need in production. No enterprise sales calls, no "book a demo" nonsense. Everything we build is open source, and we share the real stories—including the failures and dead ends.
If you're building with local LLMs, agent frameworks, or just trying to add authentication to your AI stack without losing your mind, Attach Gateway is for you.
