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 | Not 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 | Deep, repeated work inside one system |
| 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 | Reaching tools outside the CRM without a separate connector |
| 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 | A team that specifically wants a general connector reaching many unrelated tools |

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 available in the UI is also registered as an MCP tool, so a Claude session with a scoped token can do anything a person could do in the app, and any external send (email, a message, a proposal) sits in a review queue by default rather than firing immediately. Not for: a team that wants one connector reaching many different apps rather than deep control of a single CRM. SalesCrew has no customers yet and no third-party reviews.
When none of these is the answer
If the job is a one-off task, copying data from a spreadsheet into an email once, none of these integrations is worth setting up. A person doing the work directly in Claude's chat interface, pasting in the data by hand, is faster than configuring a connector or an MCP token for something that will not repeat.
MCP access is also not a substitute for reviewing what an agent actually does. However you connect Claude to a business tool, check whether writes require a human approval step before they execute, since that control lives in the tool being connected to, not in Claude itself.
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.
