Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00063 | $0.02322 |
| Opus 5 | $0.00032 | $0.01161 |
| Sonnet 5 | $0.00013 | $0.00464 |
| Haiku 4.5 | $0.00006 | $0.00232 |
Grade A, and why
canvas-discussion-facilitator 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 12d 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 — 223 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Canvas Discussion Facilitator
Facilitate discussion forum activity in Canvas LMS -- browse topics, read posts, reply to students, create new discussions, and monitor participation. Works for both students and educators.
Prerequisites
- Canvas MCP server must be running and connected to the agent's MCP client.
- The authenticated user can have any Canvas role (student, TA, or instructor). Tool access is governed by Canvas API permissions.
- FERPA-conscious handling (educators): Set
ENABLE_DATA_ANONYMIZATION=truein the Canvas MCP server environment to anonymize supported student identity fields in output. This control does not by itself establish compliance.
Steps
1. Identify the Course
Ask the user which course to work with. Accept a course code, Canvas ID, or ask them to pick from a list.
If the user does not specify, use list_courses to show active courses and prompt:
Which course should I look at discussions for?
2. Browse Discussion Topics
Call the MCP tool list_discussion_topics with the course identifier to retrieve all discussion forums.
Parameters:
course_identifier-- course code or Canvas IDinclude_announcements-- set tofalse(default) to see only discussions, ortrueto include announcements
Data to surface per topic:
- Topic ID and title
- Author name
- Posted date
- Number of entries (if available)
- Whether the topic is pinned or locked
Present the list so the user can pick a topic to drill into.
3. View Posts in a Discussion
Once the user selects a topic, call list_discussion_entries to retrieve posts.
Parameters:
course_identifier-- course code or Canvas IDtopic_id-- the selected discussion topic IDinclude_full_content-- set totrueto see complete post bodiesinclude_replies-- set totrueto see threaded replies
Data to surface per entry:
- Author name
- Posted date
- Message content (or preview)
- Number of replies
- Entry ID (needed for replying)
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.
