The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.
tg_sessionSession management — authenticate, check status, logout, or list sessions.
tg_messageSend, forward, delete, or reply to messages.
tg_chatList chats, get chat info, list members, or leave a chat.
tg_searchSearch messages, users, or channels across Telegram.
tg_historyGet chat history — messages, media only, or files only.
tg_userGet user info, get self info, block or unblock a user.
tg_mediaSend media — photo, video, file, or voice message.
tg_channelCreate, join, leave, or get info about a channel/supergroup.
tg_draftSave, list, or delete draft messages.

No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
9/9 tools missing one or more hints — tg_session (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); tg_message (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); tg_chat (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +6 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Destructive tools are labelled
1 tool perform destructive updates without destructiveHint — tg_session deletes at line 304 (p.unlink())
Add destructiveHint:true to any tool whose handler calls .delete(), .upsert(), .update(), unlink, rm, DELETE, DROP, REPLACE INTO, or any operation that overwrites existing data.
Descriptions match behaviour
1 tool describes read intent but its handler mutates — tg_session (line 304: p.unlink())
Rename the tool, rewrite the description, or move the side-effect into a separate clearly-named tool.
License file
No license file
Add a LICENSE file (MIT, Apache-2.0, etc.).
Tool description accuracy
tg_session: description implies read-only but handler writes/deletes/executes
Update tool descriptions to accurately reflect all capabilities — especially write, delete, or execute operations.
