From a79767290465d267f77f6fb01b89beb89258e1cc Mon Sep 17 00:00:00 2001 From: Claude Date: Sun, 22 Mar 2026 13:37:53 +0000 Subject: [PATCH 01/10] feat(mcp): add async task support for long-running operations (#485) Adds opt-in async execution to index_document (submit-document), reindex_library (reindex-documents), install_pack (install-pack), and all sync_connector tools (sync-slack, sync-notion, sync-confluence, sync-obsidian-vault, sync-onenote). - New `src/mcp/tasks.ts`: in-memory TaskRegistry with AbortController- based cancellation, 1-hour TTL pruning, and progress tracking - `async: true` parameter on all 7 long-running tools returns a task ID immediately; reindex and install-pack report chunk/doc progress - New `get-task` MCP tool to poll status, progress, and result - New `cancel-task` MCP tool to abort pending/running tasks - 24 new unit tests covering the full task lifecycle Backward compatible: omitting `async` preserves existing synchronous behaviour. https://claude.ai/code/session_01HRL3F1CRkRw35sUtU1eot3 --- src/mcp/server.ts | 376 +++++++++++++++++++++++++++++++++++++-- src/mcp/tasks.ts | 96 ++++++++++ tests/unit/tasks.test.ts | 242 +++++++++++++++++++++++++ 3 files changed, 703 insertions(+), 11 deletions(-) create mode 100644 src/mcp/tasks.ts create mode 100644 tests/unit/tasks.test.ts diff --git a/src/mcp/server.ts b/src/mcp/server.ts index 5a0c0b2..13bc8fb 100644 --- a/src/mcp/server.ts +++ b/src/mcp/server.ts @@ -35,6 +35,8 @@ import { initLogger, getLogger } from "../logger.js"; import { ConfigError, ValidationError } from "../errors.js"; import { errorResponse, withErrorHandling } from "./errors.js"; export { errorResponse, withErrorHandling, type ToolResult } from "./errors.js"; +import { taskRegistry } from "./tasks.js"; +import type { TaskType } from "./tasks.js"; /** Build SpiderOptions from submit-document params. */ function buildSpiderOptions( @@ -180,6 +182,40 @@ async function handleSingleDocSubmit( }; } +/** Fire-and-forget helper: creates a task, runs `work` in background, returns task ID response. */ +function startAsyncTask( + type: TaskType, + work: () => Promise, +): { content: Array<{ type: "text"; text: string }> } { + const { task, signal } = taskRegistry.create(type); + taskRegistry.update(task.id, { status: "running", startedAt: new Date() }); + void work().then( + (result) => { + if (signal.aborted) { + taskRegistry.update(task.id, { status: "cancelled", completedAt: new Date() }); + } else { + taskRegistry.update(task.id, { status: "completed", completedAt: new Date(), result }); + } + }, + (err: unknown) => { + if (signal.aborted) { + taskRegistry.update(task.id, { status: "cancelled", completedAt: new Date() }); + } else { + taskRegistry.update(task.id, { + status: "failed", + completedAt: new Date(), + error: err instanceof Error ? err.message : String(err), + }); + } + }, + ); + return { + content: [ + { type: "text" as const, text: `Task queued.

Fix: remove packages/parsers/tests from sonar.tests and add it to sonar.exclusions so Sonar does not scan those files at all. The parsers package has its own independent test run via npm workspaces.

Including it in the root Sonar project caused a false-positive duplication failure: sonar.cpd.exclusions does not apply to sonar.tests files, so the new packages/parsers/tests/unit/parsers.test.ts (104 lines, 34.1%) was flagged as duplicating the deleted-but-baseline-indexed tests/unit/parsers.test.ts. The architecturally correct fix: keep the root Sonar project scoped to src/ and tests/ only. packages/parsers should eventually get its own Sonar project configuration as the package matures.
