From ee910fc0167ad471349b88703457df825a3f3525 Mon Sep 17 00:00:00 2001 From: chenliuyun Date: Sun, 19 Apr 2026 11:38:52 +0800 Subject: [PATCH 01/17] feat(mqtt): add credential fetching and TLS client with exponential backoff MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Phase A implementation: MQTT infrastructure for event streaming. - src/mqtt/types.ts: MqttCredential, DeviceShadowEvent, StreamFilter interfaces - src/mqtt/credential.ts: fetch credential from /v1.1/iot/credential endpoint, cache with 1h TTL - src/mqtt/client.ts: TLS client wrapper with exponential backoff reconnection - Parameters: initial 1s delay, 2x multiplier, 60s max, ±20% jitter, 5 max attempts - Connection stability tracking: reset attempt counter after 30s stable - AbortSignal support for graceful SIGINT handling - package.json: version 1.4.0, add mqtt ^5.15.1 dependency - package-lock.json: synced via npm install --package-lock-only No observable behavior change yet; next phases add CLI commands. --- package-lock.json | 470 ++++++++++++++++++++++++++++++++++++++++- package.json | 3 +- src/mqtt/client.ts | 159 ++++++++++++++ src/mqtt/credential.ts | 73

Added matchShadowEventFilter that reads top-level deviceId/deviceType from the parsed shadow event. 2. ErrorSubKind extensions — introduced MqttError with subKind values mqtt-tls-failed, mqtt-connect-timeout, mqtt-disconnected (wired into ErrorSubKind union, buildErrorPayload, handleError). Credential fetch now maps 401/429 to ApiError(auth-failed/quota-exceeded) and network timeouts to MqttError(mqtt-connect-timeout). Classify initial connect failures via classifyMqttConnectError so cert errors surface as mqtt-tls-failed. 3. Runtime reconnect loop — previously MqttTlsClient only retried the initial connect; mid-session disconnects silently stopped streaming with reconnectAttempts and checkConnectionStability sitting as dead code. Now attaches a close handler post-connect that drives connectWithRetry on drop, exhausting 5 attempts before emitting an mqtt-disconnected MqttError to the registered runtime-error handler. Sleep between attempts is now abortable, so end() cancels a pending backoff immediately instead of waiting out the delay. 4. Credential cache path — replaced the literal '~' fallback with os.homedir(). Also clean up the .tmp file if the atomic rename fails so we do not leave orphan writes behind. 5. events stream smoke tests — added tests/commands/events-stream.test.ts covering extractShadowEvent parsing and the end-to-end filter path that broke before finding #1. Added tests/mqtt/errors.test.ts for MqttError classification and buildErrorPayload integration. Extended credential tests for 401/429/null-body handling. 6. Quota SIGINT/SIGTERM — quota.ts previously registered global signal handlers that called process.exit(130/143), short-circuiting command-layer cleanup (watch / events stream finally blocks). The handlers now only flush the counter; they fall back to the conventional exit code only when quota is the sole listener, so short one-shot commands keep their old behavior while long-running commands retain control of their own exit path. 7. Status cache cross-process staleness — status.json was read into a process-local hot cache with no invalidation, so a long-running MCP server could not see writes from a concurrent one-shot CLI. loadStatusCache now stats mtime before every read and reloads when the file has changed on disk; saveStatusCache/clearStatusCache/ resetStatusCache update the tracked mtime accordingly. Same-process reads remain zero-IO when mtime is unchanged. 8. /iot/credential integration — the endpoint rejected POST {} with statusCode 190 "param is invalid". The signing convention differs from the public OpenAPI: nonce is the literal string "OpenClaw" (not a UUID), the HMAC signature is NOT uppercased, the `t` header is numeric, and the body requires a 12-char random `instanceId`. Response shape is also nested under body.channels.mqtt with topics: {status: string} (wrap to single-element array for our subscribe path). Error messages surface at the outer `message` field, not body.message. Split buildCredentialHeaders from the OpenAPI buildAuthHeaders to keep both conventions clean. 9. TLS material encoding — caBase64/certBase64/keyBase64 are a misnomer: the /iot/credential response carries literal PEM text in those fields. Decoding them as base64 corrupted the material ("PEM routines::no start line"). Pass the strings through to mqtt as-is. Also align connect options with OpenClaw's reference implementation (keepalive: 60, reschedulePings: true) and dispose the prior client before reconnecting so stale listeners from a dead TCP socket do not leak.

Human mode output is unchanged. Streaming commands (devices watch, events stream/tail) keep emitting bare JSON per line — the envelope applies to one-shot responses only. Back-compat: --json-legacy opts out of the envelope and restores the v1.5.0 bare-payload shape. Planned removal in v1.7.0.

A shared ref-counted MqttTlsClient starts on the first subscriber, pushes notifications/resources/updated on every shadow event, and tears down on the last unsubscribe. A ring buffer keeps the last 100 events so a new events_recent tool can serve agents that prefer polling over subscription.

charset=UTF-8 Content-Transfer-Encoding: 8bit Add MCP tools so AI agents no longer have to shell out for common tasks: - devices_batch — run one command across many devices (yes:true for destructive) - plan_run — validate + execute a SwitchBot plan (v1.0) - webhook_setup / webhook_query / webhook_update / webhook_delete - quota_status — today's local API counter To avoid code duplication, the shared executors are extracted from the CLI actions: - runBatchCommand() in commands/batch.ts — pool + destructive pre-flight - runPlan() in commands/plan.ts — step-by-step execution loop Both helpers return structured results that the CLI and MCP paths format the same way. Destructive guards are preserved in both surfaces (yes:true via MCP maps to --yes via CLI) so agents cannot bypass them. Catalog size: 8 tools -> 15 tools.

charset=UTF-8 Content-Transfer-Encoding: 8bit Multi-tenant MCP hosts can now route each request to a different SwitchBot account by sending an `x-switchbot-profile: ` header (or `?profile=` query string). The profile name maps to `~/.switchbot/profiles/.json` and is resolved fresh per request. Changes: - createClient() accepts a `{ token, secret }` override, bypassing loadConfig() when provided. - loadConfigForProfile(profile?) — like loadConfig() but does NOT read process.argv, so it's safe for server contexts. Throws instead of calling process.exit so the HTTP handler can surface errors cleanly. - createSwitchBotMcpServer({ configResolver }) — optional resolver invoked lazily on every tool call. Defaults to loadConfigForProfile(). Every tool handler now builds its axios client via getClient() so per-request credentials are honored. - HTTP transport reads x-switchbot-profile / ?profile= and wires the resolver. Stdio transport is unchanged (one session = one profile). --- src/api/client.ts | 10 ++-- src/commands/mcp.ts | 62 ++++++++++++++++++------ src/config.ts | 33 +++++++++++++ tests/mcp/http-profile.test.ts | 88 ++++++++++++++++++++++++++++++++++ 4 files changed, 176 insertions(+), 17 deletions(-) create mode 100644 tests/mcp/http-profile.test.ts diff --git a/src/api/client.ts b/src/api/client.ts index 3a3876af..97fb4315 100644 --- a/src/api/client.ts +++ b/src/api/client.ts @@ -5,7 +5,7 @@ import axios, { } from 'axios'; import chalk from 'chalk'; import { buildAuthHeaders } from '../auth.js'; -import { loadConfig } from '../config.js'; +import { loadConfig, type SwitchBotConfig } from '../config.js'; import { isVerbose, isDryRun, @@ -36,8 +36,12 @@ export class DryRunSignal extends Error { type RetryableConfig = InternalAxiosRequestConfig & { __retryCount?: number }; -export function createClient(): AxiosInstance { - const { token, secret } = loadConfig(); +export function createClient(overrides?: Partial): AxiosInstance { + const base = overrides?.token && overrides?.secret + ? { token: overrides.token, secret: overrides.secret } + : loadConfig(); + const token = base.token; + const secret = base.secret; const verbose = isVerbose(); const dryRun = isDryRun(); const maxRetries = getRetryOn429(); diff --git a/src/commands/mcp.ts b/src/commands/mcp.ts index 1043a610..6df41414 100644 --- a/src/commands/mcp.ts +++ b/src/commands/mcp.ts @@ -29,6 +29,7 @@ import { EventSubscriptionManager } from '../mcp/events-subscription.js'; import { resolveTargetIds, runBatchCommand } from './batch.js'; import { runPlan, validatePlan } from './plan.js'; import { createClient } from '../api/client.js'; +import { loadConfigForProfile, type SwitchBotConfig } from '../config.js'; import { todayUsage } from '../utils/quota.js'; /** @@ -54,7 +55,20 @@ function mcpError( }; } -export function createSwitchBotMcpServer(): McpServer { +export interface McpServerOptions { + /** + * Resolve SwitchBot credentials for this server instance.

Capture it opportunistically in the axios response interceptor and report both local + server-authoritative numbers so agents can reason about the real remaining budget. Changes: - utils/quota.ts: in-memory serverObservation with recordServerQuota / getServerQuota / clearServerQuota helpers. todayUsage() now includes an optional `server: { remaining, observedAt }` field. - api/client.ts: response interceptor reads the ratelimit header and calls recordServerQuota(). Local counter remains authoritative for planning since the header is not guaranteed. - commands/quota.ts: human mode prints "Server remaining: N (fresh)" when the observation is <10min old. JSON mode nests it under today.server. - commands/mcp.ts: quota_status tool now returns `serverQuotaKnown` as a real boolean and the server object when present. --- src/api/client.ts | 12 +++++++- src/commands/mcp.ts | 13 ++++++-- src/commands/quota.ts | 6 ++++ src/utils/quota.ts | 30 +++++++++++++++++++ tests/utils/quota-server.test.ts | 51 ++++++++++++++++++++++++++++++++ 5 files changed, 108 insertions(+), 4 deletions(-) create mode 100644 tests/utils/quota-server.test.ts diff --git a/src/api/client.ts b/src/api/client.ts index 97fb4315..dd83b3d9 100644 --- a/src/api/client.ts +++ b/src/api/client.ts @@ -15,7 +15,7 @@ import { isQuotaDisabled, } from '../utils/flags.js'; import { nextRetryDelayMs, sleep } from '../utils/retry.js'; -import { recordRequest } from '../utils/quota.js'; +import { recordRequest, recordServerQuota } from '../utils/quota.js'; const API_ERROR_MESSAGES: Record = { 151: 'Device type does not support this command', @@ -89,6 +89,16 @@ export function createClient(overrides?: Partial): AxiosInstanc const method = (response.config.method ??

unify error envelope Review response for v1.6.0 PR #5. - plan_run now threads an AxiosInstance factory through runPlan, so HTTP- transport callers with x-switchbot-profile route to the right tenant instead of the server-default credentials. - EventSubscriptionManager takes an options-object constructor with a configResolver; when unset it falls back to loadConfig() for stdio. - MQTT credential cache file is now content-addressed (sha256 of token + secret, truncated), so two tenants on one HTTP server can't share ~/.switchbot/mqtt-credential.json. The cache is written with 0600 perms and an explicit post-rename chmod. - Replace remaining bare stderr writes of {error:...} JSON in devices, history, expand, mcp port validation, batch, config, and format with printErrorEnvelope so JSON-mode errors reliably land on stdout. - ErrorPayload.kind now includes 'guard' for the destructive-refusal branches. - New regression tests: runPlan honors getClient, credential cache is content-addressed + 0600, EventSubscriptionManager constructor shape. --- src/commands/batch.ts | 22 +++++++------- src/commands/config.ts | 10 +++---- src/commands/devices.ts | 14 +++++---- src/commands/expand.ts | 8 +++-- src/commands/history.ts | 6 ++-- src/commands/mcp.ts | 8 ++--- src/commands/plan.ts | 7 +++-- src/mcp/events-subscription.ts | 20 +++++++++++-- src/mqtt/credential.ts | 42 +++++++++++++++++---------- src/utils/format.ts | 4 +-- src/utils/output.ts | 2 +- tests/commands/plan.test.ts | 26 ++++++++++++++++- tests/mcp/events-subscription.test.ts | 4 +-- tests/mqtt/credential.test.ts | 29 ++++++++++++++---- 14 files changed, 137 insertions(+), 65 deletions(-) diff --git a/src/commands/batch.ts b/src/commands/batch.ts index f174f7a3..92d275df 100644 --- a/src/commands/batch.ts +++ b/src/commands/batch.ts @@ -1,6 +1,6 @@ import { Command } from 'commander'; import type { AxiosInstance } from 'axios'; -import { printJson, isJsonMode, handleError } from '../utils/output.js'; +import { printJson, isJsonMode, handleError, printErrorEnvelope } from '../utils/output.js'; import { fetchDeviceList, executeCommand, @@ -268,7 +268,7 @@ Examples: } catch (error) { if (error instanceof FilterSyntaxError) { if (isJsonMode()) { - console.error(JSON.stringify({ error: { code: 2, kind: 'usage', message: error.message } })); + printErrorEnvelope({ code: 2, kind: 'usage', message: error.message }); } else { console.error(`Error: ${error.message}`); } @@ -276,7 +276,7 @@ Examples: } if (error instanceof Error && error.message.startsWith('No target devices')) { if (isJsonMode()) { - console.error(JSON.stringify({ error: { code: 2, kind: 'usage', message: error.message } })); + printErrorEnvelope({ code: 2, kind: 'usage', message: error.message }); } else { console.error(`Error: ${error.message}`); } @@ -325,15 +325,13 @@ Examples: } if (isJsonMode()) { const deviceIds = blockedForDestructive.map((b) => b.deviceId); - console.error(JSON.stringify({ - error: { - code: 2, - kind: 'guard', - message: `Destructive command "${cmd}" requires --yes to run on ${blockedForDestructive.length} device(s).`, - hint: 'Re-issue the call with --yes to proceed.', - context: { command: cmd, deviceIds }, - }, - })); + printErrorEnvelope({ + code: 2, + kind: 'guard', + message: `Destructive command "${cmd}" requires --yes to run on ${blockedForDestructive.length} device(s).`, + hint: 'Re-issue the call with --yes to proceed.', + context: { command: cmd, deviceIds }, + }); } else { console.error( `Refusing to run destructive command "${cmd}" on ${blockedForDestructive.length} device(s) without --yes:` diff --git a/src/commands/config.ts b/src/commands/config.ts index 5ef76c5d..552b5bd1 100644 --- a/src/commands/config.ts +++ b/src/commands/config.ts @@ -2,7 +2,7 @@ import { Command } from 'commander'; import fs from 'node:fs'; import { execFileSync } from 'node:child_process'; import { saveConfig, showConfig, listProfiles } from '../config.js'; -import { isJsonMode, printJson } from '../utils/output.js'; +import { isJsonMode, printJson, printErrorEnvelope } from '../utils/output.js'; import chalk from 'chalk'; function parseEnvFile(file: string): { token?: string; secret?: string } { @@ -74,7 +74,7 @@ Files are written with mode 0600.
