Tools

Functions exposed to the LLM to take actions

NameDescription
get_meA

Get the identity of the authenticated Facebook user.

Resolved from the imported browser-cookie session (c_user / xs). Useful to confirm whose session is configured and whether it is still valid.

Returns: Dict with the user's id, name, and username.

get_account_statusA

Check the current cookie-session status and active Page.

Returns: Dict with valid (bool), cookie_source, me (id/name), and active_page_id / active_page_name.

set_active_pageA

Persist the active Facebook Page for display/context purposes.

Note: cookie scraping operates as the account whose cookies are imported (c_user). This tool records a Page for agent bookkeeping and for Page-mode sessions (m_page_voice cookie present). It does not switch the acting identity on its own.

list_accountsA

List all stored Facebook identities (cookie sets).

Each stored identity has its own cookies (c_user/xs); the active one is what every tool acts as. Use switch_active_account to change it.

Returns: Dict with accounts (id, name, username, identity_type, is_active, last_used), total_accounts, and active_account.

list_switchable_accountsA

Discover every identity the logged-in session can switch to.

Reads Facebook's account switcher — the Pages you administer, linked profiles, and the user profile itself. This is the discovery source an agent uses to learn which identities exist for this session.

Returns: Dict with accounts (id, name, typename, is_current) and total.

add_accountA

Store a new Facebook identity's cookie set for agent use.

The cookies dict must contain at least c_user and xs (a logged-in facebook.com session). After adding, all tools act as this identity when set_as_active is True (default).

remove_accountA

Remove a stored Facebook identity's cookie set.

switch_active_accountA

Switch which stored identity all tools act as.

Subsequent tool calls load the selected identity's cookie set, so reads and writes happen as that identity.

get_active_account_infoA

Get information about the currently active Facebook identity.

Returns: Active account metadata or a message when none is set.

update_account_cookiesA

Update cookies for an existing stored Facebook identity.

Useful for refreshing an expired session without re-adding the account.

import_account_from_browserA

Import a Facebook identity's cookies directly from a browser.

Uses the native cookie import machinery (the same as --login). The browser must be logged into that identity. Example: a Page whose session is open in your browser profile.

get_account_posting_statusB

Check a stored identity's posting limits and history.

get_page_infoA

Get Facebook Page/profile details by username.

Fetches the public (or logged-in) profile page and parses name, id, bio, and follower counts from the embedded page data.

get_page_postsA

Get recent posts from a Facebook Page's timeline.

search_pagesA

Search for public Facebook Pages by name.

get_user_postsA

Get recent posts from a user's or Page's timeline.

get_post_detailsA

Get details for a single post by its URL.

search_postsA

Search public posts by keyword.

create_postA

Publish a text post as the active (or specified) Facebook identity.

Validates the text, checks the identity's posting limits, and publishes through the web composer. If Facebook has decommissioned cookie-based writing for the account, returns a clear error rather than a false success.

create_photo_postA

Upload a photo and publish it as the active (or specified) identity.

The image is validated and normalized (resized to Facebook's feed spec) before the upload attempt. Best-effort: modern Facebook may reject cookie-based uploads; failures surface as clear errors.

create_video_postA

Upload a video and publish it as the active (or specified) identity.

The video file is validated before the upload attempt. Best-effort: modern Facebook has largely decommissioned cookie-based video uploads; failures surface as clear, honest errors.

create_carousel_postA

Upload multiple photos and publish them as one carousel post.

Each image is validated and normalized before the upload attempt. Best-effort: modern Facebook may reject cookie-based carousels; failures surface as clear, honest errors.

delete_postA

Delete one of the active (or specified) identity's own posts.

Checks the identity's posting limits, records the attempt, and deletes through the delete.php confirm flow. Fails honestly if the post is not available (already deleted) or deletion is decommissioned.

save_postA

Save/bookmark a post to the active (or specified) identity's Saved.

Best-effort: the legacy save endpoint submits the mutation but cannot always confirm it synchronously — the result tells you to verify in the Saved collection.

unsave_postA

Remove a post from the active (or specified) identity's Saved.

Best-effort: the legacy save endpoint submits the mutation but cannot always confirm it synchronously — the result tells you to verify in the Saved collection.

get_post_commentsC

Fetch comments on a post.

comment_on_postA

Comment on a post as the active (or specified) Facebook identity.

Validates the text, checks the identity's posting limits, records the attempt, and comments through the web composer. Fails honestly if cookie-based commenting is decommissioned for the account.

search_peopleA

Search for people by name.

Useful to find a person before messaging them (pair with get_conversations / send_message).

get_conversationsA

List Messenger conversations for the authenticated account.

get_conversation_messagesA

Read messages from a Messenger conversation.

send_messageA

Send a Messenger text message as the active (or specified) identity.

Validates the text, checks the identity's posting limits, records the attempt, and sends via the legacy Mercury endpoint. Fails honestly if sending is decommissioned for the account.

delete_messageA

Delete (unsend) a Messenger message as the active (or specified) identity.

Validates the ids, checks the identity's posting limits, records the attempt, and deletes via the legacy Mercury endpoint. Fails honestly if deletion is decommissioned for the account.

mark_conversation_seenA

Mark a Messenger conversation as seen (clears the unread badge).

send_typing_indicatorB

Send a typing indicator to a conversation (typing_on / typing_off).

get_groupA

Get Facebook group details.

get_group_postsA

Get recent posts from a group feed.

get_group_membersA

List members of a Facebook group.

Best-effort: served from the legacy browser-list endpoint, which may return an error for private groups or migrated surfaces — the result then explains the limitation honestly.

search_groupsB

Search for Facebook groups by name.

get_notificationsA

List the authenticated identity's recent Facebook notifications.

Includes message alerts, tags, follows, and page activity. Useful for an agent to know what needs attention before deciding to act.

get_eventsA

List upcoming events relevant to the authenticated identity.

Returns embedded event rows (id, name, start_date_time, url) from the events hub. Event details that load client-side are not available via cookie scraping.

close_sessionA

Close all active API clients and clean up resources.

Prompts

Interactive templates invoked by user choice

NameDescription

No prompts

Resources
