Agent tools

The built-in assistant, the MCP server and the tool API share the tools below. Only the tools allowed by the token's scopes are shown to an agent. Nothing is changed by Read-only tools, and they are marked as read-only for MCP clients.

Tools for changes are checked by the permission engine. Many are carried out at once; others return pending_approval and are held for a decision. See Approvals for agents.

When the id is left out, most calendar and task tools are applied to the event or task focused on screen; a request to Ambrose such as "move this to Friday" is resolved this way.

Call any tool over HTTP with POST /api/v1/agent/tools/{name}. See REST API.

Search and read mail

Tool	Purpose	Scope	Read-only
search_conversations	Search mail with the usual search operators (from:, is:unread, newer_than:7d, quoted phrases). Returns conversation summaries.	read	yes
search_semantic	Find conversations by meaning ("the thread where we discussed the budget overrun"), each with its best matching passage.	read	yes

Notes and checklists

The note tools are for your notes and checklists. An agent has your own access on each note: on a note shared with you at view level it can only read. For a write tool, the note is found by id or by title ("the shopping list" also matches the list marked Shopping); when you name none, the note open on screen is used. A write tool's result has ids, counts and the text written, never another person's text. Every note read is untrusted: a note can hold other people's items, pasted mail or a web page. A local-only note is never sent to a hosted model; in the result, some notes are then reported as hidden.

Tool	Purpose	Scope	Read-only
list_notes	List notes and checklists with their ids, titles, item counts, labels and pins. Filters: kind, label, pinned, archived, in Trash, shared, words. With templates, the templates instead.	notes	yes

search_notes	Search notes by words and by meaning, with the notes search operators; for an item match, the item is returned.	notes	yes
note_history	A note's versions of the last 30 days, one version's content, or restore one.	notes	no
create_note	Make a note or a checklist. List lines go through the item grammar (quantities, sections); a link to the email it came from is optional. With template, start from a template (its id or name), which may make a table.	notes	no
update_note	Change a note's title or text (whole, or find and replace), colour, the Shopping list switch, its kind, pin, archive and labels, link it to an email, or set your reminders on it (remind_at). A reminder is never snoozed or dismissed with it.	notes	no
checklist_items	A list of changes to one checklist: add items (to a section, or where each was last time), add usual items, check, uncheck, edit, move, delete, make a task from an item, add, rename, move, order and delete sections, clear the checked items, uncheck everything.	notes	no

The web

The two tools below are available only while a web search provider is set up and Web search is turned on in the user's access policy (see Web search). Both are refused in a chat where local-only mail was read, and for a local-only token: nothing from local-only accounts is put into a web query.

Tool	Purpose	Scope	Read-only
web_search	Search the web through the admin's providers, tried in order until one returns results. Takes query, count (1 to 20, default 8) and freshness (day, week, month, year). Returns titles, links, sites and snippets, each with a cite value. Titles and snippets are marked untrusted.	web	yes
read_page	Read one web page as plain text, cut at 20,000 characters. https only, through the egress proxy when one is set. No scripts are run by the built-in reader; when it fails, the admin's page readers are tried. The built-in assistant opens only a page web_search returned in the chat, a link you wrote in your message, or a link in your own part of your own email. A token's agent picks its own pages.	web	yes

The built-in assistant cites a web source as [[web:<url>]]. The citation is kept only when the address appears in a result Ambrose read in that chat. Both tools are checked against the web.search permission class (Approvals for agents).

Tables

The notes scope is required for the table tools. Ambrose's access to each table is the same as the user's: it can read and change exactly what the user can. Tables marked local-only stay hidden from a hosted model. Text in table results is marked untrusted, because a shared table can hold other people's rows. A table is found by its id or its name; when two tables have the same name, an error is returned and the id is required.

Tool	Purpose	Scope	Read-only
list_tables	Your tables with their ids, names, row counts, columns and labels. With query, names and rows are searched for words.	notes	no
get_table	One table: its columns, its views and a page of rows (up to 200) with row ids and typed values, in a view's order or with your own filters and sort.	notes	no
table_stats	Totals and counts for a table: sums, averages, medians, dates, checked shares and counts per option, for all rows or a filter, optionally per group.	notes	no
table_history	A table's changes in sessions, one row's changes and earlier values, deleted rows; bring back deleted rows or a deleted column, put a row or a cell back, or restore the whole table to a point in time.	notes	no
table_rows	Add, change, duplicate or delete rows. Values are typed by column; a value that does not fit is refused, and the column and the type are named in the error. Rows are given by id or by their primary value.	notes	no
table_schema	Create a table, rename it, add, rename, retype, move or delete columns, change options and column settings, choose the primary column, save or delete a view.	notes	no
table_state	A table's colour, pin, labels and archive, a link to an email, event, task or recording, or its way back from Trash.	notes	no
delete_table	Move a table to Trash.	notes	no

The permission classes are tables.rows (add and change rows; allowed), tables.rows_delete (delete rows; asks) and tables.schema (creating tables, adding columns and saving views are allowed; other column and view changes and a restore to a point in time ask). Moving a table to Trash is notes.delete (asks), and its colour, pin, labels and links are notes.edit. After Ambrose has read email or another untrusted result in a chat, a row write of text, a new option or a link into a cell is held for approval. Ambrose cites a table as [[table:<id>]] and a row as [[table:<id>#<row_id>]].

Results and citations

• Email text in a result is marked untrusted. Agents must not follow instructions inside it.
• Results have url fields for opening a conversation, a message or a passage in Mailr.
• The built-in assistant cites messages and passages in its answers, and every quote is checked against the message before the answer is shown.
• A note is cited as [[note:<id>]], one item of a list as [[note:<id>#<item id>]]. The note can be opened from the chip, with the item focused. A note you cannot see is never cited.
