Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@ClassApp MCP search school notices from this week about field trips"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
A local-first MCP connector that helps parents find school notices, read message contents and save attachments in a private directory. It runs over stdio and uses only a small set of fixed operations. Offline mode is the default.
Unofficial community project. Not affiliated with, endorsed by or supported by
ClassApp or any school. This is an early 0.1.0 candidate using undocumented
web endpoints; changes by the provider may break it. It does not replace the
official app, school communication or professional advice. The source distribution
is davidmosiah/classapp-mcp.
There is no npm release or hosted service; this experimental source is intended
for local evaluation, with provider permission requirements unchanged.

Tool | Behavior |
| Show mode and limits without testing provider access |
| List profiles available to the configured session |
| Search notices with bounded pagination |
| Read message content with read-status update flags disabled |
| Save an attachment belonging to the selected message; return local path, size and SHA-256 |
There are no send, reply, delete, login, refresh-token or arbitrary-API tools. Downloads create a new local file and are therefore annotated as local writes. The connector never opens, executes, transforms or uploads downloaded files.

Requires Node.js 24+ and a trusted MCP client. macOS is the validated platform; Linux runtime/harness compatibility is not yet verified. Windows is unsupported by the owner/permission checks. Inspect the source before running it. Clone the source repository and enter its root:
git clone https://github.com/davidmosiah/classapp-mcp.git
cd classapp-mcp
npm ci --ignore-scripts --no-audit --no-fund
npm run build
CLASSAPP_MODE=offline node dist/index.jsA stdio server waits for an MCP client; a quiet terminal is normal. Configure the client with examples/mcp.offline.json, replacing both absolute paths with your installation. The examples contain no live account data. Offline results are synthetic and do not demonstrate live access.
For real notices, follow SETUP. Live access requires your own existing authorized session, a private credential file outside every Git checkout and a private download directory. A token is sent only to the fixed ClassApp GraphQL host for authentication, not to the download proxy. The MCP client receives notice contents; if it uses a cloud model, those contents may leave your computer under that client's policy. This is not an end-to-end privacy guarantee.
Read operations explicitly disable observed read-receipt update flags. A sample checked on 2026-10-21 retained unread state; this is historical, limited observation, not a guarantee of future backend behavior or no server-side logs. Do not use the connector when an unnoticed read would carry serious consequences. The official app remains the source for urgent notices and confirmation.
Notice text, filenames and attachments are untrusted data, never agent instructions. Keep sending, shell execution and unrelated integrations behind your MCP client's approval controls. No connector can guarantee that a model will ignore a malicious notice.
Use only accounts and profiles you are entitled to access. Review the provider's current terms and your school's rules before connecting. An account's ability to read material does not authorize publishing it, sharing it with an AI service or redistributing it. MIT covers this connector's code; it grants no rights to ClassApp, school or third-party content. See responsible use.
npm run verifyTests are synthetic and never read personal credentials or call live providers.
The suite covers real stdio discovery/workflow, strict arguments, fixed GraphQL
operations, network restrictions, safe errors and filesystem permissions. Planted
regressions in disposable copies must be rejected for their intended assertions.
Build before running tests: they import the compiled candidate in dist/.

Licensed under MIT.
Live use has not been approved by the provider. Enable it only after obtaining any permissions required by the provider, school and affected data subjects, including sharing with your AI client. The provider’s privacy policy (item 2.18, consulted 2026-11-02) directs users to keep information in-platform and not share personal/protected content without authorization. Manual session configuration is not a way to bypass login, 2FA or provider restrictions.
Download an attachment belonging to a message into the configured private directory. Creates a new random local file; never overwrites. Returns path, bytes and SHA-256. Does not send messages or request read-status updates. No arbitrary URL or filename is accepted.

Scored across 5 tools
Each tool targets a distinct operation (status, entity listing, notice search, message read, attachment download), but search_notices and read_message both return message-related content, which could cause occasional misselection. Descriptions clarify the boundary reasonably well.
All tools use a consistent snake_case, classapp_-prefixed pattern with clear verb_noun naming (list_entities, search_notices, read_message, download_attachment). The lone noun-only status tool is a conventional and readable exception.
Five tools is well-scoped for a focused read-only notice/message inspection server. Each tool has a clear, non-redundant role and the surface is neither thin nor bloated.
The surface covers the apparent read-only lifecycle: check status, pick an entity, find notices, read a message, and download its attachment. Minor gaps exist, such as no explicit way to list all attachments for a message or paginate beyond hasMore, but core workflows are covered.
