MCP Apps Testing Server
A comprehensive testing suite demonstrating all Model Context Protocol (MCP) Apps features through interactive Weather Dashboard and 3D Globe viewer applications.
Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.
show-clockrun-clockExecute the clock timer: tick N times with a given interval, sending a notifications/progress message for each tick. Called by the show-clock UI app — pass a progressToken in _meta to receive real-time tick notifications.
show-mapshuffle-citiesgeocodeSearch for places using OpenStreetMap. Returns coordinates and bounding boxes for up to 5 matches.
test-resources-notificationTriggers a resources/list_changed notification to demonstrate dynamic resource list updates.
test-tools-notificationTriggers a tools/list_changed notification to demonstrate dynamic tool list updates.
show-weathercompare-weathershow-lifecycleshow-host-contextshow-messagingshow-domain-corsshow-themingecho-toolEchoes the provided message back. Used by conformance tests.
slow-taskRuns for a specified duration, sending progress notifications. Supports cancellation via signal.
slow-echoEchoes a message after a delay with progress notifications. Supports cancellation.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
@modelcontextprotocol/sdk has cross-client data leak via shared server/transport instance reuse
Anthropic's MCP TypeScript SDK has a ReDoS vulnerability
vite: `server.fs.deny` bypass on Windows alternate paths
Vite Vulnerable to Arbitrary File Read via Vite Dev Server WebSocket
Vite has an `server.fs.deny` bypass with an invalid `request-target`
DECLARED_DOMAININPUTPORTDependencies
16 dependencies, 2 flagged: @playwright/test, @axe-core/playwright
Tool annotations
No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
37/37 tools missing one or more hints — show-clock (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); run-clock (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); run-clock (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +34 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Tool inputs are validated
7/11 tool handlers declare input schemas (64%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
8/11 tool handlers wrap calls in try/catch (73%)
Wrap each tool handler body in try/catch and return a structured error response.
License file
No license file
Add a LICENSE file (MIT, Apache-2.0, etc.).
Tool test coverage
Only 4/37 tools referenced in tests (11%)
Write tests that reference each tool by name so every tool has at least one test.
Production dependencies are patched
0 critical, 4 high severity in production deps — @modelcontextprotocol/sdk@1.24.0 (high), @modelcontextprotocol/sdk@1.24.0 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.

Add it once and ask Claude, ChatGPT, or any MCP client to grade a server, surface CVEs, check the publisher, and suggest safer alternatives — before you install.
