VS Code extension that connects AgentStack MCP so you can use the live AgentStack action catalog (Projects, Auth, Scheduler, Analytics, Rules Engine, Webhooks, Notifications, Wallets, Payments, Buffs, Agents, Storage, Support, and more) via one tool (agentstack.execute) from chat and agent mode.
JSON-based data store (8DNA: JSON+ with built-in variants, e.g. A/B tests) and server-side logic without boilerplate.
- Install the extension from the Marketplace or load the VSIX.
- Sign in — run AgentStack: Sign in with Device Code for OAuth browser login. If OAuth is unavailable, run AgentStack: Create project and get API key or AgentStack: Set API Key as the fallback.
- Use in chat — select @agentstack for read-only fast paths (list projects, stats) and LM tools (
agentstack_execute,agentstack_get_projectswhen supported). For full catalog coverage use manual MCP setup in MCP_QUICKSTART.md or Copilot agent mode with MCP configured.
More options (curl, dashboard) in MCP_QUICKSTART.md.
All actions are available in Chat when you select the @agentstack participant (through agentstack.execute). Example prompts by domain:
| Domain | Example prompts in chat |
|---|---|
| Projects | List my AgentStack projects, Get stats for a project, List users in the selected project (slash commands) — the extension fetches real data from the API directly. Or say "list my projects", "get stats", "list users", "project details" / "список проектов", "статистика", "пользователи проекта". For other requests (e.g. "Create a project named Test") the model uses MCP tools; responses use only tool data, never invented examples. |
| 8DNA / Data | "Store project data at key config.theme", "Read user data" |
| Rules Engine | "Create a rule when user signs up", "List logic rules" |
| Buffs | "Give user a 7-day trial", "List active buffs" |
| Payments | "Create a payment", "Get wallet balance" |
| Auth | "Get my profile", "Quick auth with email" |
| Scheduler, Analytics, Webhooks, Notifications, Wallets | "Schedule a task", "Get analytics", "List webhooks" |

After creating a project: The API key is saved in the extension and used automatically. To copy it elsewhere, run AgentStack: Set API Key (paste the same key) or AgentStack: Show API key & project info (preview and copy).
| Feature | Description |
|---|---|
| Stable MCP setup path | Marketplace build avoids proposed APIs. Use the sidebar/chat participant directly, or follow MCP_QUICKSTART.md to add the MCP server in VS Code manually. |
| Ecosystem view | AgentStack sidebar: Status (Set API key / Connected); Projects — Refresh, Create project, then your projects (or "No projects — Create project"); Project detail (when a project is selected) — Summary, Data (preview), Users, Settings, Scheduler (if you have read permission: list tasks, run from tree; use Chat to create), Capabilities (Buffs, Payments, Rules, 8DNA — links to docs; use @agentstack in Chat for more), Unselect project; Documentation (MCP Server Capabilities, 8DNA & Key-Value API, Plugins index). Right-click any node for context menu (e.g. Copy project ID, Refresh). |
| Project data & settings | From the tree: Summary / Data (preview) → AgentStack: Show project data in editor (full project JSON); Settings → AgentStack: Open project settings in editor (view/edit data.config). After editing the JSON, run AgentStack: Save project settings from editor to push changes via MCP. Use Unselect project under Project detail to clear selection. User data (user.data) is available via key-value API — see Documentation → 8DNA; for per-user data you can ask in Chat (@agentstack). |
| Status bar | Shows "AgentStack (ProjectName)" or "AgentStack (project id)" when a project is selected, or "Set API key"; click to set key or see key & project info. |
| Open documentation | AgentStack: Open documentation (Command Palette) opens the Plugins index and doc links. |
| Create project and get key | AgentStack: Create project and get API key — creates an anonymous project (no account), saves the API key, and connects MCP in one step. |
| OAuth / API key | OAuth Device Code stores a Bearer token in SecretStorage. API keys remain a fallback through AgentStack: Set API Key. |
| Project switcher | AgentStack: Switch project shows a QuickPick of real projects and stores the selected project for sidebar/chat context. |
| Chat skills | 22 domain skills for @agentstack (projects, hosting, storage, support, rag, agents, commerce, messenger, …) — decision-first routing; live catalog via GET /mcp/actions. |
| Capability | AgentStack | Typical DB-only |
|---|---|---|
| Data model | 8DNA (JSON+): structured JSON; key-value store (project.data, user.data); built-in support for variants (e.g. A/B tests) | Flat tables |
| Server logic | Rules Engine (when/do, no code) | Triggers / custom backend |
| Trials & subscriptions | Buffs | Custom or 3rd party |
| Payments | Built-in gateway | Separate integration |
| API surface | One MCP tool (agentstack.execute) with live action discovery + REST APIs | CRUD + auth |
- API key — From Settings or command; empty = use key from secure storage (Set API Key).
- Base URL — MCP server URL (default:
https://agentstack.tech/mcp). Change only for self-hosted AgentStack. - Request timeout — Timeout for MCP/server calls in seconds (1–300, default 60).
- Enable Chat Participant — Turn @agentstack chat on/off.
- Debug / Strip artifacts — Toggle if chat output looks wrong (e.g. raw tool names in the answer). Enable Debug Chat Response and check Output → AgentStack MCP to see whether the response came from the direct API path or from the model (helps diagnose fake/example project lists).
- @agentstack doesn't show or chat says it's unavailable — Command Palette (Ctrl+Shift+P) → Developer: Reload Window. Then run AgentStack: Set API Key or AgentStack: Create project and get API key once, and try @agentstack in Chat again.
- Where does AgentStack MCP appear? — The Marketplace build does not register MCP through proposed APIs. Use the @agentstack chat participant and sidebar commands, or follow MCP_QUICKSTART.md to add the MCP server manually through VS Code's stable/user setup flow.
- AgentStack tools still not available — Reload the window, run any AgentStack command from the Command Palette, then open Chat and choose @agentstack. Check Output → AgentStack MCP for trace-first diagnostics.
