Why plug your budget sheet into Claude
Tiller drops your bank transactions into a spreadsheet. The connector means no more filtering columns or exporting CSVs: you ask Claude a money question the way you'd ask a friend, it pulls the rows from your sheet itself, and the answer comes back in the chat using your own category names.
See exactly where the money went. query_transactions queries your transactions. Tiller says Claude reaches your transactions, categories and other Tiller data this way, with nothing to export or paste by hand.
Use the words your sheet uses. list_categories returns your category list. That matters because Claude sticks to exact names: ask about "Dining Out" when the category is called "Restaurants" and nothing matches.
Clear the uncategorized backlog. update_transactions writes to the Transactions tab, assigning categories and adding notes. Tiller describes a two-step exchange where Claude first shows its proposed categories, then asks whether to apply them.
Now the parts the directory sheet leaves out. Writing only works on Direct Fills sheets. Claude retrieves 500 transactions per call and pages through the rest, so a full-year review runs slower. Categories marked "hide from reports" are excluded by default. And nothing runs on its own: no tool fires when a new charge lands. That job belongs to an automation tool, which is a different trade; the Integrations hub covers that side.
The jargon, in one minute
Five terms you'll run into while connecting Tiller.
- Connector
- The link you set up once between Claude and an account you already have, so Claude can work in it while it answers you.
- Tool
- One named thing a connector lets Claude do. Claude picks the ones it needs by itself, and the directory lists them by name.
- Authorization
- Tiller's own sign-in screen, where you hand Claude the access it will use. Granted once per person and withdrawn the same way.
- Approval
- The confirmation Claude waits for before finishing something that changes your account, shown in the chat right when it matters.
- MCP
- The shared standard connectors are built on, the piece that lets an assistant like Claude talk to an outside service.
Connect Tiller to Claude in three steps
- 01
Find Tiller in Claude
In Claude's settings, open Customize, then Connectors, and look for Tiller in the list. On a Team or Enterprise workspace, an Owner or Primary Owner has to switch the connector on first so members can sign in.
- 02
Start the connection
Hit Connect on its row and sign in through the window Tiller opens. If the link breaks later, choose Disconnect and connect again. Tiller notes you can manage or disconnect it at any time from Settings → Connectors.
- 03
Check the authorization screen
Read the authorization screen before you accept. It belongs to Tiller, not Claude, and it decides what the access covers. You can also pull that access back later from your Tiller account.
All 4 tools, grouped by what they do
Tiller gives Claude 4 tools: 2 that read your account, 1 that change something in it, and 1 no official source describes.
Three groups: what Claude reads, what it changes, and what no official source describes. Tool names stay exactly as Claude shows them.
- 2 read
- 1 write
- 1 not documented
What Claude reads (2)
2 toolsTwo tools that look at your sheet without touching it.
list_categories
Brings your category names into the chat exactly as they're spelled in your sheet. Claude then works from those labels for every answer, with no fuzzy matching or synonyms.
query_transactions
Reads your transactions straight from Tiller, so you can ask Claude about your spending without exporting the sheet or pasting rows into the chat.
What Claude changes (1)
1 toolOne tool that writes to the Transactions tab, after you confirm according to Tiller.
update_transactions
Asks you firstSaves changes into the Transactions tab of your sheet: a category on rows that were blank, or a note on a specific charge.
Undocumented (1)
1 toolThe directory publishes this name and nothing else. No official text says what it does, and we won't guess from the name.
list_spreadsheets
This name is on the directory's tool list, and that's all we know. Neither Tiller's help article nor any Claude page describes it, so this page gives it no capability, read or write.
What Claude checks with you first
By default, Claude stops and asks before every action it takes on an account for you. The request shows up in the chat at the moment it counts.
Tiller describes that moment for its connector: Claude lists the categorization it intends to apply, then waits for your reply before touching the sheet. Tiller also warns that an "Always Allow" prompt may pop up several times along the way. On Team and Enterprise workspaces, owners decide whether members can let some actions through without being asked again, and can shut off writing for the whole org. Claude works with your Tiller access and nothing beyond it.
Which plans include it
None of the 819 sheets in the official directory shows plan availability. Nobody publishes that answer connector by connector.
Anthropic does publish a general rule: remote connectors are open to all users on Claude, Cowork, Claude Desktop and mobile, and on Team and Enterprise an Owner or Primary Owner turns each one on for the org first. Tiller has its own line on the topic, set side by side with Anthropic's in the limits section. For the live status, check the Tiller sheet in the official directory.
Where this connector stops
A connector isn't an automation. Claude calls these tools while it answers you, so nothing kicks off when a new transaction syncs.
Only Tiller documents this connector: neither Claude's help center nor Anthropic's developer docs have a page on it, so everything below comes from the publisher's help article dated August 2026. The directory's partner badge isn't a security audit either, and Anthropic says so on every sheet: it doesn't choose a publisher's tools or guarantee how they behave. Tiller also flags that its ready-made prompts haven't been thoroughly tested.
Which Claude plans can use this connector?
- Claude Help Center, general connector rule ↗September 2026Remote connectors are open to all users; on Team and Enterprise, an Owner must turn each one on first.
- Tiller help article ↗August 2026The publisher says a free Claude account is enough to get started, with usage limits that depend on the plan.
What this page followsNeither text is out of date. Tiller speaks about its own connector, Anthropic about all of them, and neither settles it for your account. Check the directory sheet while signed in: that's where the current status lives.
