ParentSquare MCP Server

An MCP (Model Context Protocol) server that gives Claude access to ParentSquare, a school-parent communication platform. Since ParentSquare has no public API, this server scrapes the web interface using saved session cookies.

Covers both the parent/guardian experience (feeds, posts, calendars, messages, directories, sign-ups, forms, payments) and school admin roster management — reading student and guardian rosters, and creating/editing students and guardians plus sending registration invitations. Admin write tools are off by default, gated behind PS_ENABLE_WRITES, and every write is recorded to a local audit log.

Available on the MCP Registry as io.github.thehesiod/psquare and on PyPI as parentsquare-mcp.

Admin

Read tools are always available; the tools marked *(write)* below are disabled by default and only run when PS_ENABLE_WRITES is set (see Enabling admin write tools). Every write *attempt*, including one blocked by the gate, is recorded to a local audit log. No tool deletes a record — students, guardians, classes, and staff can be created and edited but never deleted, and the tools that remove something only unlink a relationship (a staff assignment, class enrollment, or group membership), leaving the underlying people, classes, and groups intact. Deletion is deliberately left to the ParentSquare website.

Roster: students & guardians

• `list_students` — School roster (id, name, grade, SIS id, guardians) as structured JSON, with optional grade / name_contains filters
• `list_parents` — Guardian roster (user_id, name, email, phone, linked students) as structured JSON, with optional name_contains / student_name_contains filters; provides the user_id needed by edit_parent / link_guardian_to_student
• `list_grades` — A school's grades and their grade_id values (needed for add/edit)
• `get_student` — Admin detail for one student (name, grade, SIS id, linked guardians, classes)
• `add_student` *(write)* — Create a student in a grade
• `edit_student` *(write)* — Update a student's name, SIS id, or grade (unchanged fields preserved)
• `add_parent` *(write)* — Create a guardian linked to a student
• `edit_parent` *(write)* — Update a guardian's name, email, or phone (existing links preserved)
• `link_guardian_to_student` *(write)* — Link an existing guardian to an additional student
• `invite_parent` *(write)* — Send (or resend) a ParentSquare registration invitation to one guardian
• `bulk_invite_parents` *(write)* — Invite many guardians at once; already-registered guardians are skipped automatically

Classes, staff & enrollment

• `list_classes` / `get_class` — A school's classes, and one class with its full staff list (teachers, assistants, room parents)
• `add_class` *(write)* — Create a class; new classes start hidden until set_class_visibility
• `edit_class` *(write)* — Rename a class or change its grades
• `set_class_visibility` *(write)* — Show or hide classes (date-driven, defaults to today)
• `list_staff` — Staff and admin roster (user_id, name, email, phone, role/title) as structured JSON, with an optional name_contains filter; provides the user_id needed by edit_staff / add_class_staff
• `add_staff` *(write)* — Add a teacher, staff member, or admin, optionally assigning them to classes
• `edit_staff` *(write)* — Update a staff member's name, email, phone, title, or staff ID (class assignments and STAFF/ADMIN access preserved; guardians are rejected — use edit_parent)
• `add_class_staff` / `remove_class_staff` *(write)* — Assign or unassign teachers, assistants, and room parents for a class. Section-membership writes are serialized inside one server process; never issue them in parallel, and verify each result with a fresh read.
• `list_class_students` — The students enrolled in a class
• `add_class_students` / `remove_class_students` / `move_student_to_class` *(write)* — Manage which students are enrolled in which classes. These share the same global serialization lock as class-staff writes because student-section updates can replace a student's full enrollment list.

Group membership

• `add_group_members` *(write)* — Add existing people to a manually selected group (group_id, user_ids). Preserves saved user/student selections, owners, managers, and existing guests; skips people already present. Does not create accounts or invite new guests.
• `remove_group_members` *(write)* — Remove explicit ordinary/guest members, one verified operation per person. Refuses empty targets, owners/managers, and groups with student-derived membership; skips absent people. Stops on an uncertain result and reports previously verified changes.

Group writes currently support manually selected (CsvGroup) groups, not rule-based groups or ownership changes. They share the class/enrollment write lock, validate complete directory reads, and verify both membership and saved selections after each write. Use them serially, even across server processes. Classroom Room Parent roles and membership of a Room Parents group are independent.

Authentication

• `submit_mfa_code` — Complete MFA verification with a 6-digit code
• Supports MCP elicitation for inline MFA prompts (set PS_NO_ELICIT to disable for unattended callers)
• Session cookies persisted to ~/.parentsquare_cookies.json
• Credentials loaded from environment variables, 1Password, or LastPass CLI on session expiry

Setup

Enabling admin write tools

The admin write tools — every tool marked *(write)* under Admin, covering the student/guardian roster, classes, staff, class enrollment, and groups — modify live school data, so they are off by default. To enable them, set PS_ENABLE_WRITES=1 (or true/yes/on) in the server's environment and restart. Every write attempt (including blocked ones) is appended as JSONL to PS_AUDIT_LOG (default ~/.parentsquare_audit.log). The admin read tools work regardless.

ParentSquare's form endpoints answer every accepted POST with the same generic 200 "reload" response, which some silent failures also return. To avoid false-positive successes, the create/link tools (add_student, add_parent, link_guardian_to_student) read back authoritative state after the write and only report ✅ Success (verified) once the new record is actually found. If the POST is accepted but the read-back can't find the change, they return a ⚠️ warning that it likely did not persist; if the read-back itself can't run, they report the write as submitted-but-unverified.

The read-back also overrules a 5xx. ParentSquare renders its error page *after* the transaction commits, so a server error can hide a write that actually landed — add_student did exactly that on every create until a missing studentsection_ids form param was tracked down. Reporting those as failures invited retries, and each retry duplicated a real student with no API route to delete one. So when a write returns a 5xx but the record is found on read-back, the tool reports ✅ Success (verified) with a note not to retry. An explicit rejection (a 4xx, or a 200 carrying an alert-danger flash) is still reported as a failure regardless of read-back.

Prerequisites

Credentials can be provided in either of two ways (checked in this order):

1. Environment variables — set PS_USERNAME and PS_PASSWORD
2. A credential manager selected by PS_CREDENTIAL_PROVIDER (default 1password):

• [1Password CLI](https://developer.1password.com/docs/cli/) (op) — with a "Parentsquare" item containing username and password fields
• [LastPass CLI](https://github.com/LastPass/lastpass-cli) (lpass) — set PS_CREDENTIAL_PROVIDER=lastpass. Run lpass login in a terminal first (may prompt for MFA). The item read defaults to parentsquare.com and can be overridden with PS_LASTPASS_ITEM (an exact entry name or entry ID).
