Claude Spark connectorWhat Claude can do in your Spark account.
The Claude Spark connector exposes 19 tools: 14 read, 5 write, 0 undocumented. Claude reads your inboxes, calendars and meeting notes, drafts and triages mail, and can send when you allow it. Here: the access levels Spark enforces and what runs only on your computer.

What changes when your inbox runs your day
Spark is an email app that gathers Gmail, Outlook, Exchange, iCloud, Yahoo and IMAP accounts in one place. With the extension in Claude Desktop, you ask Claude about your mail in plain words: it searches the threads, reads attachments, checks your calendar, then drafts, files or snoozes messages within the access level you picked in Spark.
Clear the backlog after a trip. search finds the threads on a topic, thread reads them in full, and action archives, snoozes or labels what can wait.
Answer without starting from a blank page. draft prepares a reply, a forward or a message from one of your saved Spark templates, and can share it with a teammate for review before anything leaves.
Book the follow-up meeting. availability finds free slots, then event creates the invitation, once send access is on for that account.
Now, what the directory sheet does not tell you. Spark decides what Claude may do, account by account: read-only, triage (drafts, comments, email and contact actions) or send (mail and calendar invitations too). Spark Desktop must be open on macOS or Windows, with its command-line bridge enabled, because the extension talks to it locally. And nothing fires on its own: no tool wakes up when a message arrives. Routing every incoming invoice to accounting is an automation tool's job, a different trade; the Integrations hub covers that side.
The vocabulary, in one minute
Five words you will meet while plugging Spark in.
- Connector
- The link you set up once between Claude and an account you already use, 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 during the answer, and the directory sheet lists them by name.
- Authorization
- The step where you hand Claude the access it will use on a service. Granted once per person, and it can be taken back.
- Approval
- The confirmation Claude waits for before it goes through with something that changes an account, shown in the chat when it matters.
- MCP
- The shared standard connectors are built on: it is what lets an assistant like Claude talk to an outside app such as Spark.
Plug Spark into Claude in three steps
- 01
Find Spark in Claude Desktop
Spark ships as a desktop extension, so open Claude Desktop. In the settings, go to Customize, then Connectors, and look for Spark. On a Team or Enterprise workspace, an Owner or Primary Owner must switch it on before members can use it.
- 02
Start the connection
Click Connect on its row and complete what Spark asks for. If the link breaks later, use Disconnect, then plug the extension back in from the same row.
- 03
Set what Claude may touch
The service, not Claude, decides what the access covers. In Spark's own AI agent settings, give each account and shared inbox its level: read-only, triage or send. The level stays adjustable in that same place.
The 19 tools, sorted by what they do
Spark gives Claude 19 tools: 14 that read your account, 5 that change something in it.
Fourteen tools consult your mail, calendars and meetings, five act on them. Names stay as Claude shows them, in English.

What Claude reads (14)
14 toolsFourteen tools that look into Spark without changing anything.
accounts
Shows every email account set up in Spark, along with its calendars, teams and shared inboxes. It tells Claude where to look before it searches anything.
folders
Returns the folders of an account with how many messages sit in each, a quick picture of where mail piles up and where Claude should look next.
emails
Lists messages with their metadata, page by page, and accepts the same kind of filters you would type in Gmail's search bar. Claude gets the list first and decides which threads deserve a full read.
search
Finds emails by topic, mixing keyword matching with meaning, so a question phrased loosely still lands on the right threads.
thread
Opens a whole conversation with headers, message bodies and attachments, so Claude can summarise it, spot who is waiting on whom, or quote the one reply that matters.
attachment
Reads one attachment by its ID and returns its content, whether image, audio, text or other, downloading it first if Spark has not cached it yet.
events
Returns calendar events over a time range you choose, across the calendars Spark knows about for your accounts. Claude can then point out clashes or empty afternoons.
availability
Looks for open time slots for scheduling. The directory sheet adds that it can find mutual availability with teammates, which saves the usual round of "does Tuesday work for you?".
contacts
Searches your contacts by name or email address, which helps Claude address a message to the right person when two people share a first name or a company domain.
team
Displays team information in Spark: who belongs to the team and which conversations are assigned to whom. Handy before handing a thread to somebody who is already swamped.
meetings
Returns the meeting transcripts Spark holds, as a list to pick from before reading one in detail. It is the index; the reading happens with the next tool.
meeting
Reads one meeting's summary, full transcript and notes, so Claude can pull decisions, owners or next steps out of it and phrase them for whoever missed the call.
templates
Shows the message templates saved in Spark, both your personal ones and those shared by the team, so Claude knows which ready-made replies exist before drafting from scratch.
template
Displays one saved template, found by ID or by name, together with the placeholders it expects to be filled in, such as a client name or an amount.
What Claude changes (5)
5 toolsFive tools that act on your mail, calendar or contacts. No source describes a confirmation of their own: the general rule below applies, on top of Spark's access levels.
event
Approval: see the ruleCreates, edits or deletes a calendar event, answers an invitation, and adds or removes attendees. Spark requires send access on the account for this one.
draft
Approval: see the rulePrepares or edits a draft: new message, reply, reply-all, forward, or one built from a saved template, with attachments and a markdown body. It can also delete a draft, list signatures and share the draft with teammates.
comment
Approval: see the rulePosts a team chat comment on a thread, and shares the thread with the team first if it was not already shared.
action
Approval: see the ruleArchives, pins, snoozes, moves, labels, assigns, shares or marks mail as done, reclassifies its category, and can send or schedule a draft, among other actions.
contact-action
Approval: see the ruleBlocks or accepts a sender, changes a contact's category, marks it important or primary, and turns auto-summary on or off.
What Claude asks before it acts
By default, Claude stops and asks for your go-ahead before each action it takes on an account in your place. The request appears in the conversation, right when it matters.
Spark adds a second lock of its own: each account and shared inbox gets a level, and writing or sending only works where you enabled it. On Team and Enterprise, owners decide whether a member can let some actions through without being asked every time. They can also cap what a connector may do for the whole organization, keeping reads and closing writes, and nobody overrides that from their own account. Finally, Claude works with your rights and nothing more.
Which plans it works on
Of the 819 sheets in the official directory, none displays availability plan by plan. The answer for a given connector is published nowhere.
The general rule is public: remote connectors are open to all users on Claude, Cowork, Claude Desktop and mobile, and desktop extensions such as Spark install on Claude Desktop. On Team and Enterprise, an Owner or Primary Owner switches a connector on for the organization before members can connect. For the current state of this one, check Spark's sheet in the official directory.
Where this connector stops
A connector is not an automation. Claude calls these tools while it answers you: nothing happens by itself when an email lands or an invitation comes in.
The tool list is an observed floor, not a promise: an admin can open actions no public sheet shows. The partner badge is not a security audit, and Anthropic writes on every sheet that it neither picks a publisher's tools nor vouches for how they behave. Everything here comes from Spark's own repository, since neither Claude's help center nor Anthropic's developer docs cover it. For a sheet of the same kind, see the Claude asana connector.
