Best Claude integrations for business
Connecting Claude to real business data means either a general connector like Zapier MCP, or a tool that ships its own MCP server. Compared on cost and what Claude can actually do once connected.

Zapier MCP wins for reaching the widest number of existing tools with the least setup, since it already connects to thousands of apps and treats an MCP tool call as a normal task in its pricing. A tool with a native MCP server, such as Attio or SalesCrew, wins instead when the job is deep, repeated work inside one system rather than light touches across many.
The short answer
- Claude's Free plan costs $0/month; Pro is $17/month billed annually ($20 monthly) with more usage, per claude.com/pricing.
- Zapier MCP is available from the Free tier (100 tasks/month) through Enterprise, and an MCP tool call consumes 2 tasks from the shared pool, per zapier.com/pricing.
- A native MCP server, like the one Attio lists on every tier including its free plan, skips the connector layer entirely: Claude calls the tool directly rather than through a general automation platform.
Ways to connect Claude to business tools
| Option | Starting price | Reach | Setup | Best for |
|---|---|---|---|---|
| Zapier MCP | Free (100 tasks/mo), paid from $19.99/mo (750 tasks, annual) | Thousands of connected apps | Low, connect via Zapier's existing app library | Light-touch actions across many different tools |
| Attio (native MCP server) | Free (up to 3 seats) to $99/user/mo (Pro, monthly) | One CRM, deep access | Moderate, issue and scope an MCP token | A team standardizing on one CRM Claude can operate directly |
| SalesCrew (native MCP server) | $299/mo (Core, unlimited seats) | One CRM, every action has an MCP twin | Moderate, issue a scoped MCP token per user | A team that wants every UI action also callable by Claude, with human approval on external sends |

How the three approaches differ
Zapier MCP
The broadest reach by far, since it rides on Zapier's existing library of app connections rather than requiring each individual tool to build its own MCP server. The tradeoff is depth: an MCP call through Zapier is still shaped by whatever that app's Zapier integration exposes, which is usually narrower than a tool's full native functionality. Not for: work that needs the CRM's full action set, not only the subset Zapier wired up.
Attio
Lists an MCP server as a workspace feature across every tier, including its free plan for up to 3 seats, which makes it one of the more accessible ways to let Claude operate inside a real CRM without an enterprise contract. Pricing runs from free to $99/user/month on Pro (monthly), or $79 billed annually. Not for: a team that also needs Claude to reach tools well outside the CRM.
SalesCrew
Disclosure: SalesCrew is our product. Every action in the UI is also an MCP tool. A Claude session with a scoped token can do anything a person can do in the app. Any external send, an email, a message or a proposal, waits in a review queue by default. Best for: a team that wants deep, controlled work inside one CRM.
How to choose
Choose Zapier MCP if you want Claude to touch many apps lightly with little setup. Choose Attio or SalesCrew if Claude will do deep, repeated work inside one system. For a one-off task, pasting the data into Claude's chat by hand is quicker than any connector.
However you connect Claude, check whether writes wait for a human approval before they run. That control lives in the tool you connect to, not in Claude. In SalesCrew, every AI action waits in one approval queue you control.
Questions
- What is the cheapest way to connect Claude to business tools?
- Claude's own Free plan costs nothing, and Zapier's Free tier includes 100 tasks a month with MCP access, per zapier.com/pricing, so a very light integration can run at zero cost. Anything past a handful of actions a month needs a paid tier on one side or the other.
- Does Zapier MCP work with any AI tool, or only Claude?
- Zapier markets its MCP server as giving 'AI tools access to thousands of apps instantly,' not as Claude-specific, per zapier.com/pricing. It works with any MCP-compatible client, of which Claude is one.
- What does an MCP server actually let Claude do in a CRM?
- It gives Claude the same actions a person has in the app, exposed as callable tools instead of buttons, so Claude can read a record, draft a reply, or update a deal stage the same way a user would in the interface, subject to whatever permissions the token was issued with.
- Is it safe to let Claude write to a CRM through MCP?
- That depends entirely on how the specific CRM scopes tokens and whether external actions require human approval before they execute. Ask any vendor directly whether writes go through a review step or execute immediately, since that answer varies by product and by which mode an agent is set to.
