What is canvas-parent-mcp CLAUDE.md?

Project instructions for canvas-parent-mcp, a program that connects coding tools to Canvas, a learning-management system used by schools and universities.

Use them when building, testing, running, or authenticating the Canvas MCP server and its QR-login helper.

They give contributors the project commands, structure, authentication details, and operating boundaries needed to work on the code consistently.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.03919	$0.03919
Opus 5	$0.01959	$0.01959
Sonnet 5	$0.00784	$0.00784
Haiku 4.5	$0.00392	$0.00392

Security

Grade A, and why

canvas-parent-mcp CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 226 lines — stays where its author put it; the contents beside it link to each section on GitHub.

canvas-parent-mcp

MCP server for Canvas LMS (Instructure). Stdio transport, read-mostly tools scoped for student self-access and parent observers (mirrors sibling infinitecampus-mcp's parent-portal scope).

The npm package is canvas-parent-mcp because canvas-mcp and canvas-lms-mcp are both taken. Tools, env vars, and the user-facing skill stay branded canvas / Canvas because that's what users say.

Commands

npm run build        # tsc + esbuild bundle → dist/
npm test             # tsc typecheck + vitest run (all tests)
npm run test:watch   # vitest in watch mode
npm run dev          # node --env-file=.env dist/index.js (needs prior build)

dist/ is gitignored; CI rebuilds it and the published npm tarball includes it (files array in package.json).

Bins

canvas-parent-mcp → dist/index.js — the MCP server (stdio).
canvas-parent-mcp-qr-login → dist/qr-login-cli.js — one-off helper that decodes a Canvas mobile-login QR URL and prints OAuth env vars to stdout. Used for SSO accounts that can't use username/password.

Architecture

src/
  index.ts            # MCP server entry — loads dotenv, runs resolveAuth(), builds client, registers all tools
  auth.ts             # resolveAuth(): four-path priority (token → OAuth → session-scrape → fetchproxy → error). Template for sibling MCPs
  config.ts           # loadAccount(env) → discriminated union Account = TokenAccount | SessionAccount | OAuthAccount
  client.ts           # CanvasClient: auth+401-retry, pagination, download. Custom error types. Accepts a `refreshSession` browser lift from the fetchproxy path
  session-login.ts    # POSTs /login/canvas form, harvests pseudonym_credentials cookie (legacy path 3)
  qr-login.ts         # Mobile QR → mobile_verify.json → authorization_code exchange → OAuth tokens (bootstraps path 2)
  qr-login-cli.ts     # Thin CLI wrapper around qr-login (printed as env vars)
  view.ts             # CV_VIEWS/viewArg/viewResponse — the `view` rung (compact default, full opt-in). Wired ONLY into the reads whose Canvas payload embeds a user object; see its docblocks for the KEEP/DROP reasoning
  tools/
    _shared.ts        # textContent(), buildPath(), userSegment(), is404(), toArray()
    profile.ts        announcements.ts   calendar.ts        conversations.ts
    courses.ts        discussions.ts     files.ts           grades.ts

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
