From fa38da78384e40e9fc208261efd5b2e4e2c1bedc Mon Sep 17 00:00:00 2001 From: cryptotavares Date: Wed, 15 Apr 2026 22:19:16 +0100 Subject: [PATCH 01/36] refactor: decompose mcp-server into modular architecture with CLI entry point Restructure monolithic src/mcp-server/ into focused modules: - src/server/: HTTP server, daemon state, port allocation, request queue - src/tools/: all tool implementations and type definitions - src/knowledge-store/: knowledge store and tokenization - src/validation/: schema validation - src/utils/: shared logger, errors, time utilities - src/cli/: new CLI entry point (mm) Add SKILL.md and update package.json, README, and vitest config. --- README.md | 1755 ++++------------ SKILL.md | 368 ++++ package.json | 12 +- src/capabilities/context.test.ts |

This allows parallel work across branches. +- **Port Allocation**: The daemon automatically allocates ports for the HTTP server and test infrastructure (Anvil, fixture server, mock server) to avoid conflicts. +- **Auto-Start**: The daemon starts automatically on `mm launch` if not already running, and shuts down after a period of inactivity (default: 30 minutes). +- **Request Serialization**: A `RequestQueue` (async mutex) ensures only one tool executes at a time, preventing race conditions on shared browser state. +- **Health Checks**: Each daemon generates a unique nonce on startup. The CLI verifies daemon identity via `GET /health` to detect stale `.mm-server` files from crashed processes. +- **Logs**: Daemon activity is logged to `.mm-daemon.log`. -#### BuildCapability (Optional) +### Session Manager Interface -Enables the `mm_build` tool.

Accepts build type and force options. | +| `launch` | Launches a new browser session with the configured extension. Supports state modes (`default`, `onboarding`, `custom`), fixture presets, goal/tag metadata, and optional contract seeding on start. | +| `cleanup` | Tears down the active browser session and cleans up all resources (browser, services, fixtures). | +| **Interaction** | | +| `click` | Clicks an element identified by a11y ref, test ID, or CSS selector. Waits for the element to be visible before clicking. | +| `type` | Types text into an input element identified by a11y ref, test ID, or CSS selector. Uses Playwright's `fill()` for reliable input. | +| `wait_for` | Waits for an element to become visible on the page within a configurable timeout. | +| `clipboard` | Reads from or writes to the system clipboard via Chrome DevTools Protocol. Useful for pasting seed phrases or copying addresses. | +| **Navigation** | | +| `navigate` | Navigates the browser to a named screen (`home`, `settings`, `notification`) or an arbitrary URL. | +| `switch_to_tab` | Switches the active page to a tab matching a given role (e.g., `extension`, `dapp`) or URL prefix. | +| `close_tab` | Closes a browser tab matching a given role or URL. Falls back to the extension tab if the active tab is closed. | +| `wait_for_notification` | Waits for the extension notification popup to appear within a timeout. Returns the notification page URL. | +| **Discovery** | | +| `describe_screen` | Captures a comprehensive screen snapshot: extension state, visible test IDs, trimmed a11y tree with refs, optional screenshot, and prior knowledge from historical sessions. | +| `accessibility_snapshot` | Captures a trimmed accessibility tree of the current page with deterministic refs (`e1`, `e2`, ...). Supports scoping to a root CSS selector. | +| `list_testids` | Collects all visible `data-testid` attributes from the current page with text previews and visibility status. | +| **State** | | +| `get_state` | Retrieves the current extension state (URL, screen, network, balance, account) and tracked tab information. | +| `get_context` | Returns the current environment context (`e2e` or `prod`), session status, available capabilities, and whether context switching is allowed. | +| `set_context` | Switches the session environment between `e2e` and `prod` modes. Blocked while a session is active. | +| **Screenshots** | | +| `screenshot` | Captures a screenshot of the current page. Supports naming, full-page capture, scoping to a CSS selector, and optional base64 output. | +| **Knowledge** | | +| `knowledge_last` | Retrieves the N most recent step records from the knowledge store, with optional scope and filter parameters. | +| `knowledge_search` | Searches step records by query string with token-based matching and synonym expansion. Scores results by relevance to screen, URL, test IDs, and a11y nodes. | +| `knowledge_summarize` | Generates a recipe-style summary of a session's tool invocations, showing the step sequence with targets and outcomes. | +| `knowledge_sessions` | Lists available knowledge sessions with metadata (goal, flow tags, timestamps), with optional filtering. | +| **Contracts** | | +| `seed_contract` | Deploys a single smart contract to the local Anvil chain by name. Requires `ContractSeedingCapability`. | +| `seed_contracts` | Deploys multiple smart contracts in sequence. Returns both successful deployments and individual failures. | +| `get_contract_address` | Looks up the deployed address of a contract by name from the session's deployment registry. | +| `list_contracts` | Lists all contracts deployed in the current session with addresses and deployment timestamps. | +| **Batching** | | +| `run_steps` | Executes a batch of tool invocations sequentially. Supports `stopOnError` to halt on first failure. Returns per-step results with timing. | - // Screenshots - async screenshot(options: { name: string; fullPage?: boolean }) { - // ... screenshot logic - return { path: '', base64: '', width: 0, height: 0 }; - } +### Accessibility References - // Capabilities - getBuildCapability() { - return this.buildCapability; - } - getFixtureCapability() { - return this.fixtureCapability; - } - getChainCapability() { - return this.chainCapability; - } - getContractSeedingCapability() { - return this.contractSeedingCapability; - } - getStateSnapshotCapability() { - return undefined; - } +The core uses Playwright's `ariaSnapshot()` to build a deterministic reference map of interactive elements.

Accepts build type and force options. | -| `launch` | Launches a new browser session with the configured extension. Supports state modes (`default`, `onboarding`, `custom`), fixture presets, goal/tag metadata, and optional contract seeding on start. | -| `cleanup` | Tears down the active browser session and cleans up all resources (browser, services, fixtures). | -| **Interaction** | | -| `click` | Clicks an element identified by a11y ref, test ID, or CSS selector. Waits for the element to be visible before clicking. | -| `type` | Types text into an input element identified by a11y ref, test ID, or CSS selector. Uses Playwright's `fill()` for reliable input. | -| `wait_for` | Waits for an element to become visible on the page within a configurable timeout. | -| `clipboard` | Reads from or writes to the system clipboard via Chrome DevTools Protocol.

Accepts build type and force options. | -| `launch` | Launches a new browser session with the configured extension. Supports state modes (`default`, `onboarding`, `custom`), fixture presets, goal/tag metadata, and optional contract seeding on start. | -| `cleanup` | Tears down the active browser session and cleans up all resources (browser, services, fixtures). | -| **Interaction** | | -| `click` | Clicks an element identified by a11y ref, test ID, or CSS selector. Waits for the element to be visible before clicking. | -| `type` | Types text into an input element identified by a11y ref, test ID, or CSS selector. Uses Playwright's `fill()` for reliable input. | -| `wait_for` | Waits for an element to become visible on the page within a configurable timeout. | -| `clipboard` | Reads from or writes to the system clipboard via Chrome DevTools Protocol. Useful for pasting seed phrases or copying addresses. | -| **Navigation** | | -| `navigate` | Navigates the browser to a named screen (`home`, `settings`, `notification`) or an arbitrary URL. | -| `switch_to_tab` | Switches the active page to a tab matching a given role (e.g., `extension`, `dapp`) or URL prefix. | -| `close_tab` | Closes a browser tab matching a given role or URL.
