How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security57
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation check failed: no authorisation is required to call this server, and it exposes a tool marked destructive (submit_assignment). See how to fix → View diagnostics → Fail
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability79

- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management27
- Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- All 2 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation.Pass
- An AI judge read all 67 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass

The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability.

post_qna_question ~164
Post a new question to a course's Q&A board. IRREVERSIBLE and VISIBLE to the instructor once dry_run=False (posted as private/secret by default). Call with dry_run=True (default) first, show the preview to the user, and only call again with dry_run=False after they explicitly confirm.

process_quiz_attempt ~210
Submit answers for a quiz attempt. IRREVERSIBLE once dry_run=False AND finish_attempt=True -- that is the final, graded submission and cannot be undone. UNVERIFIED against a real quiz. Call with dry_run=True (default) first, show the preview to the user -- especially before finish_attempt=True -- and only call again with dry_run=False after they explicitly confirm.

remove_submission ~238
Withdraw/clear this account's own submission for an assignment. IRREVERSIBLE and DESTRUCTIVE once dry_run=False -- this discards already-submitted work (files/text), not a draft. KNOWN ISSUE: live testing found dry_run=False currently fails with an "invalid parameter" error from PLATO every time (the real required parameter shape wasn't determined -- see remove_submission_for's docstring). dry_run=True (preview) works and is safe to call. Do not rely on dry_run=False actually working until this is fixed. Call with dry_run=True (default) first, show the preview to the user, and only call again with dry_run=False after they explicitly confirm.
| Name | Type | Req | Description |
|---|---|---|---|
| assignment_id | integer | yes | Assignment id, e.g. from list_assignments. |
| course_id | integer | yes | PLATO/Moodle numeric course id, e.g. from list_courses. |

| Name | Type | Req | Description |
|---|---|---|---|
| search_text | string | yes | Text to search for in course names. |
| Name | Type | Req | Description |
|---|---|---|---|
| result | array | yes | – |
No examples provided.
start_quiz_attempt ~153
Start a new attempt at a quiz. IRREVERSIBLE once dry_run=False -- consumes one of the quiz's limited attempts. UNVERIFIED against a real quiz -- call get_quiz_access_information first and check canattempt/preventaccessreasons. Call with dry_run=True (default) first, show the preview to the user, and only call again with dry_run=False after they explicitly confirm.
| Name | Type | Req | Description |
|---|---|---|---|

| message | string | yes | – |
| preview | object | yes | – |
No examples provided.
submit_assignment ~484
Submit text and/or file attachments for an assignment. IRREVERSIBLE once dry_run=False. Call with dry_run=True (default) first, show the preview to the user, and only call again with dry_run=False (same parameters) after they explicitly confirm. Provide text, file_paths/file_contents, or both -- whichever this assignment actually accepts (see get_assignment_detail). file_paths works only when this server is running locally (stdio, e.g. Claude Code/Desktop) -- rejected with a clear error over a remote (streamable-http, e.g. a Claude.ai Connector) connection, mirroring download_course_file's own stdio-vs-remote split. file_contents works over either transport and is the only option remotely, since this server's disk is not reachable by you there.

| assignment_id | integer | yes | Assignment id, e.g. from list_assignments. |
| course_id | integer | yes | PLATO/Moodle numeric course id, e.g. from list_courses. |

How do I install the PLATO MCP server?
PLATO MCP is a hosted endpoint at https://plato-mcp.onrender.com/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.
