Works with any MCP client

01 The relay

One endpoint, every tool.

Point your AI client at localhost:9400. Every MCP server you've configured — filesystem, GitHub, Notion, Slack, your custom tools — is available through that single connection. Add or remove servers without touching your client config. Multiple Linear Projects, Multiple Slack Workspaces, Multiple Gmail Accounts — install the same server as many times as you need and give each a short description the model sees on every tool.

  • stdio · sse · http · oauth — every transport unified
  • Tools auto-prefixed to avoid collisions (github__create_issue)
  • Install the same server multiple times — give each a description (oss), (proj-a) the model sees on every tool
  • Hot-reload — edit config, the relay picks it up without restart

A native desktop app for macOS, Windows, and Linux. Browse the marketplace, add endpoints with one click, monitor health, inspect tools and schemas, view logs. No TOML editing required.

  • Curated marketplace · ~15 servers ready to add
  • Health dots, restart counters, live status
  • Tool inspector with full input schemas
  • Real-time relay logs · system tray · runs in background

03 Cloud OAuth

Sign in to cloud services, once.

Linear, Notion, Slack, GitHub, Craft — sign in through your browser and Endara handles the rest. Token refresh, lifecycle management, and automatic reconnection. Your AI client gets access to cloud tools it couldn't reach on its own.

  • OAuth 2.1 with PKCE — no plaintext client secrets
  • Auto-refresh before token expiry
  • Re-authorize from the app if needed
  • Works with any server supporting OAuth discovery (RFC 9728)

04 JS execution mode

50 tools? Use three.

When you connect dozens of MCP servers, the tool list overwhelms the model. Endara collapses your entire catalog into three meta-tools — search, list, and execute — and the model writes JavaScript to call any combination of tools in one shot.

  • Fuzzy search with typo tolerance
  • Sandboxed Boa engine — no filesystem or network access
  • Multi-tool orchestration in a single round-trip
  • Open source — works with any tools, not just OpenAPI

06 Open source

Open source. Your machine. Your data.

The relay is Apache-2.0 Rust. The desktop app is Apache-2.0 too. Everything runs on your machine — no cloud account, no data leaving your network, no vendor lock-in. Fork it, extend it, self-host it.

endara-ai/endara-relay
The MCP relay. A small Rust binary that aggregates servers, handles OAuth, and exposes one endpoint.
RustApache-2.0 3v0.1.5
endara-ai/endara-desktop
The desktop app. Tauri 2 + SvelteKit. Bundles the relay and gives it a face.
