A Claude connector links Claude to another app, so it can find information there and take actions for you. Anthropic's directory listed 872 connectors on September 30, 2026. These are the ones that cover a salesperson's working day, grouped by job, with what each can read and what it can change.
“Best” here means three things you can check: the connector is published by the vendor itself, it is listed in Anthropic's connector directory, and it covers a step of sales work. We have not tested one vendor's data against another's, so this list is grouped by job and does not rank one CRM or data provider above the next.
We make Buena, which connects to Claude as a custom connector and is not in the directory, so it appears near the end. Every other fact comes from Anthropic's directory and documentation, checked on September 30, 2026. What each connector does is taken from its directory listing.
What a Claude connector is
Anthropic describes a connector as a link between Claude and an outside app or service, “so Claude can find information there and take actions for you”. You sign in with your own account for that service, and Anthropic notes that the service is run by its provider, which may require its own account or paid plan.
Each directory listing carries a label. Verified means Anthropic tested the connector's tools for quality and compatibility; Anthropic adds that this “isn't a security audit or a guarantee”. Community means Anthropic screened the connector but has not reviewed it in depth. Every connector in the table below showed the Anthropic verified label when we checked.
A label does not change who runs the connector. The vendor operates it and controls its tools, which can change after review, so the advice is the same for all of them: connect only services you trust, and read the access each one asks for.

Each is made by the company it is named for, except Gmail and Google Calendar, which Google makes. You need an account with each service, so only the connectors for tools you already use are worth adding. Two or three will cover most of a selling week.
Your CRM: HubSpot, Salesforce, Attio, Pipedrive and Close
A CRM connector lets Claude answer from your account history instead of asking you to paste it in. HubSpot's listing shows 27 tools and says the connector can search and update contacts, companies, deals and tickets. Salesforce's connector is labelled Beta; Salesforce says it works while “honoring Salesforce security, permissions, and governance”. Pipedrive says its connector respects your existing user permissions, and its 32 tools include ones that add deals, people, activities and notes.
Attio's tools create and update records and tasks, create notes, and search emails, meetings and call recordings. Close is the most explicit about writing: it reads by default, and during setup you choose whether to allow only safe writes, such as creating a lead, or full writes that can edit and delete.
Start here if your team works from a CRM. Let Claude read first. Allow it to write once you have seen what it writes.
Prospect data: Apollo, ZoomInfo, Clay and Lusha
These four find people and companies and fill in contact details. Apollo's tools search and enrich, singly or in bulk, pull a company's job postings, create and update contacts and add contacts to sequences. ZoomInfo's search and enrich, and return intent signals, news, funding events and what ZoomInfo calls executive-change scoops. Clay's find and enrich contacts and companies. Lusha's search, enrich and return buyer signals.
Each works on your own account with that vendor. Apollo and Clay charge credits for enrichment, as our guides to Apollo pricing and Clay pricing explain, so check what a request will cost before you run it on a long list.
One tool needs particular care. Apollo's listing includes a tool that adds contacts to a sequence. Sequences exist to send email, so set that tool to Needs approval.
The directory lists other data connectors too, among them RocketReach, Crunchbase, Common Room and Vibe Prospecting. Connecting several at once can pay twice to enrich the same person, so pick one source and add a second only when it covers people the first misses.
Email, calendar and meeting notes
Google makes the Gmail and Google Calendar connectors. Gmail's searches and reads threads, creates drafts and manages labels, and its 29 listed tools also include reply, forward and send. Google Calendar's finds events and free time, creates, updates and deletes events, and responds to invitations. If your company uses Outlook, Anthropic's own Microsoft 365 connector searches Outlook email and calendar alongside SharePoint, OneDrive and Teams.
Meeting notes give Claude what was said on a call, which is what a good follow-up is built from. Granola's connector queries your notes and returns transcripts. Fathom's returns summaries, transcripts and action items. The tools both list only read. Fireflies and Zoom have connectors too.
Because the Gmail connector can send, set its send, reply and forward tools to Needs approval before you use it.
Outreach platforms: Outreach and Salesloft
Outreach's connector searches prospects, accounts, opportunities, sequences and emails. Salesloft's reads accounts, people, opportunities, conversations and call transcripts, and Salesloft says role-scoped permissions mean you see only your own data.
The tools both list are lookups. Neither lists a tool that enrolls a prospect or sends a message, so these connectors inform a draft rather than send one. Tool lists can change, so look at the listing before you rely on that.
What is not in the directory
We found no connector published by LinkedIn among the 872 listings. Unofficial LinkedIn servers exist, and our guide to MCP servers for sales explains why connecting one puts your account at risk.
A tool that is missing from the directory can still be connected. Anthropic says directory connectors and custom connectors use the same technology, so if a vendor gives you a server address, you can add it yourself. That is how Buena connects.
Buena as a custom connector
Buena is not in Anthropic's directory. You add it by its address, and Anthropic labels connectors added this way Custom and has not reviewed them, ours included.
https://mcp.buena.ai/mcpOn Free, Pro and Max plans, open Customize, then Connectors, select the plus button, choose Add custom connector and enter the address. On Team and Enterprise plans, an Owner adds it under Organization settings, then Connectors, and members then connect it. Free plans are limited to one custom connector.
Once connected, Buena finds people with a reason to reach out, reveals verified work emails and prepares draft campaigns with personal messages. It works under your Buena permissions and does not activate a campaign or send a message on its own: sending needs an explicit approval, which you give in Buena or by confirming Buena's approve step in Claude. Claude can be told to always allow a tool, so set Buena's approve-and-activate tool to Needs approval. That way every send comes back to you. Setup for ChatGPT, Claude Code and Codex is on our MCP page.
How to add a connector, and the permissions to set
- Open Customize, then Connectors, and select Discover to browse the directory or search for a service.
- Open the connector's page and select Connect to Claude. Sign in to the service and approve the access Claude asks for.
- On Team and Enterprise plans, an Owner adds the connector for the organization first. Members then connect their own account.
- Select the connector under Your connectors and set its tool permissions: Always allow, Needs approval or Blocked, for a single tool or a group.
- In a chat, select the plus button, then Connectors, to turn a connector on or off for that conversation.
A sensible default: Always allow for tools that search and read, Needs approval for anything that creates, updates, sends or spends credits, and Blocked for deletes you never want. Anthropic says connectors you add in Claude are also available in Claude Code when you sign in with your Claude account; our Claude Code for sales guide covers that setup.
Which to add first
- Your CRM, reading only at first, so every answer can draw on account history.
- One source of new prospects: Apollo, ZoomInfo, Clay, Lusha or Buena.
- Your meeting notes, so follow-ups start from what was said.
- Email and calendar last, with send, reply and forward set to Needs approval.
Add them one at a time and run the same request after each, such as a brief on one account. You will see what each connector contributes, and you will notice if one starts doing something you did not ask for.
