feat(server): add MCP tool annotations to all tools for marketplace compliance - #375
Merged
Conversation
…ance Add title, readOnlyHint, destructiveHint, idempotentHint, and openWorldHint to every server.tool registration (45 tools), with values matched to each tool's actual behavior: - readOnlyHint: true for fetch/list/get/setup-instruction tools; false for tools that create, upload, run, or modify state - destructiveHint: true for overwrite-style updates (updateTestCase, updateTestRun, managePercyBuildApproval) - idempotentHint: true for readers and same-args-same-result updates; false for create/run/upload tools - openWorldHint: true only for runBrowserLiveSession (interactive browser on arbitrary third-party sites); false elsewhere - title: human-readable display name on every tool Required for Claude Connectors Directory (title + hints are mandatory) and OpenAI app submission (accurate readOnlyHint/openWorldHint/ destructiveHint required per tool). Tests updated to bind the handler from the last server.tool argument so the added annotations object doesn't shift positional assumptions. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Second half of the per-tool annotation change: accessibility, appautomate, percy-sdk, rca-agent, selfheal, testmanagement tool files plus test updates that bind the handler from the last server.tool argument. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

What
Adds complete MCP tool annotations (
title,readOnlyHint,destructiveHint,idempotentHint,openWorldHint) to all 45server.tool()registrations, with values audited against each tool's actual behavior (HTTP verbs in utils, side effects like app uploads and session creation, in-memory store usage).Why
Required for marketplace submissions:
titleand the applicablereadOnlyHintordestructiveHint"; the submission portal flags tools missing titles or annotations.readOnlyHint,openWorldHint, anddestructiveHinton every tool, matched to actual behavior.Annotation values
readOnly: true, idempotent: truesetupBrowserStackAutomateTests, Percy setup/scan tools,prepareSelfHealingPlan, RCA tools)readOnly: false, idempotent: falsestartAccessibilityScan,createAccessibilityAuthConfig,takeAppScreenshot,runAppTestsOnBrowserStack, live-session tools, TM create/upload/addResult toolsreadOnly: false, destructive: true, idempotent: trueupdateTestCase,updateTestRun,managePercyBuildApprovalopenWorld: truerunBrowserLiveSessiononly — interactive browser on arbitrary third-party sites (per OpenAI's definition: can change publicly visible internet state)Every tool also gets a human-readable
title(e.g.createAccessibilityAuthConfig→ "Create Accessibility Auth Config").Verification
npm run buildpasses (lint + format + 276/276 tests + tsc)tools/listserver.tool()argument so the inserted annotations object doesn't break positional assumptionsNotes
getFailuresInLastRun(observability.ts) got annotations too but is currently never exposed —addObservabilityToolsis missing fromtoolAddersinserver-factory.ts(pre-existing; flagged separately, not fixed here).🤖 Generated with Claude Code
