This repository has moved — do not build from it
Development of
@ikenga/mcp-iykecontinues in the ikenga-pkgs monorepo:→ Royalti-io/ikenga-pkgs/packages/mcp/iyke
This repo was last updated on 15 May 2026 and is now archived and read-only.
Why this matters if you cloned it. The state left here is neither the last release nor the current one: its
package.jsondeclares0.1.2, but its source carries a partially-migrated tool set from the period before the code moved back into the monorepo. Building from this tree gives you something that was never published. Anything you install from npm is unaffected.

A Model Context Protocol server that exposes the Ikenga desktop app's iyke control bridge — so any MCP client (Claude Code, Cursor, custom agents) can drive a running Ikenga session the same way a developer types into the iyke CLI at a shell.
What this is
Ikenga is a Tauri-based AI workspace shell with a manifest-driven package kernel. While the app is running, it exposes a localhost HTTP server (with a bearer token in control.json) that lets external tools introspect and drive the live UI: switch panes, navigate routes, take DOM snapshots, click elements, read logs, capture screenshots.
This package wraps that HTTP server in MCP so an LLM agent can use it natively. Tools mirror the iyke CLI subcommands.
Install
Via Claude Code (recommended)
After that, any Claude Code session can call iyke_state, iyke_go, iyke_mode, iyke_open, iyke_split, iyke_focus, iyke_close, plus the runtime-inspection tools (iyke_dom, iyke_logs, iyke_network, iyke_screenshot, iyke_wait, iyke_click, iyke_type, iyke_key, iyke_query_cache, iyke_devtools), iframe tools (iyke_iframe_state, iyke_iframe_send) and project tools (iyke_project_create, iyke_project_update, iyke_project_list, iyke_project_archive, iyke_project_set_active, iyke_project_get_active).
Via npx (no install)
From source (for contributors)
Then point your MCP client at node /path/to/ikenga-pkg-mcp-iyke/dist/index.js.
Tools
Layout & navigation
| Tool | Purpose |
|---|---|
iyke_state | Show current sidebar mode + focused pane's route + full pane tree. |
iyke_go | Navigate the focused pane to a route path. |
iyke_mode | Switch sidebar activity mode. |
iyke_open | Open a new tab in the focused pane (route, terminal, chat, artifact, mini-app). |
iyke_split | Split a pane horizontally or vertically. |
iyke_focus | Focus a pane by id or 1-based DFS leaf index (⌃1..⌃6). |
iyke_close | Close a pane (focused if pane_id omitted). |
Runtime inspection & driving
| Tool | Purpose |
|---|---|
iyke_dom | Accessibility-tree snapshot of the focused pane (Playwright-style refs). |
iyke_logs | Last 500 console + error logs from the running webview. |
iyke_network | Last 100 fetch/XHR network entries with status + duration. |
iyke_screenshot | PNG screenshot of the window or a specific pane. |
iyke_wait | Wait until a predicate is satisfied (text/selector/ref/gone). |
iyke_click | Click an element by ref, selector, or text. |
iyke_type | Type into an input/textarea/contenteditable. |
iyke_key | Dispatch a keyboard combo (e.g. Ctrl+S, Meta+K). |
iyke_query_cache | Dump the TanStack Query cache for the focused pane. |
iyke_devtools | Open Chrome DevTools (debug builds only). |
Iframe runtime state
| Tool | Purpose |
|---|---|
iyke_iframe_state | Read the latest published state object for an iframe pane. |
iyke_iframe_send | Send a fire-and-forget postMessage to an iframe pane. |
Projects
| Tool | Purpose |
|---|---|
iyke_project_create | Create a project (slug + display name; optional root_path, icon, color, description). |
iyke_project_update | Patch fields on an existing project (display_name, root_path, icon, color, description, position). |
iyke_project_list | List projects in switcher order; pass include_archived=true to surface archived ones. |
iyke_project_archive | Soft-delete a project; refuses to archive the built-in Default project. |
iyke_project_set_active | Switch the shell's active project; refetches project-scoped queries. |
iyke_project_get_active | Return the currently active project. |
Trust boundary
The MCP server reads control.json from the platform-specific app-local-data directory (~/Library/Application Support/app.ikenga/control.json on macOS, $XDG_DATA_HOME/app.ikenga/control.json on Linux, %APPDATA%/app.ikenga/control.json on Windows). The control file contains:
port— localhost port the in-app HTTP server is listening ontoken— bearer token required on every requestpid— owning process PID (used to detect stale files)
A stale control.json left behind by kill -9 is auto-deleted once it's at least 5 minutes old; younger stale files are reported (likely a launch race) so we don't clobber a starting app.
If the Ikenga desktop app isn't running, every tool call fails with a structured error rather than hanging — your agent reads the failure and reports it instead of silently waiting.
The MCP server only ever talks to 127.0.0.1 on the port from control.json, with the bearer token from the same file. No outbound network, no telemetry.
Compatibility
- Ikenga shell: any version exposing the v1
control.jsonschema. - Node.js: ≥ 20.
- Bun: runs without compilation (
bun src/index.ts). - MCP SDK:
@modelcontextprotocol/sdk^1.23.0.
Versioning
This package follows SemVer 2.0.0. Major-version bumps may break MCP tool names or argument shapes; minor bumps add new tools or non-breaking improvements; patches fix bugs.
The iyke HTTP protocol version (the in-app server's API surface) is independent — it's pinned via schema_version: 1 in control.json. This package currently supports protocol v1 only.
