Bonsai MCP with Claude: Automate Client Onboarding, Invoicing and Contracts
The short answer
Claude works with Bonsai through the Model Context Protocol, an open standard that acts as a secure adapter between the two. Once connected, Claude can read client, project and billing information and carry out approved actions such as creating invoices or updating contracts, using the access your organisation chooses to grant.
What is Bonsai?
Bonsai is an all-in-one business management platform built for freelancers and agencies. It brings contracts, invoicing, client relationship management and project workflows into a single dashboard, so small teams do not need to juggle separate tools for each job. Freelancers use it to run their own practices, while agencies use it to keep client work, billing and paperwork organised across several people.
How Claude connects to Bonsai through MCP
The Model Context Protocol, or MCP, is an open standard that lets Claude use other software securely. Think of it as a universal adapter between Claude and a business tool. It gives Claude a defined set of things it is allowed to read and do, and nothing beyond that.
Once Bonsai is connected, Claude can typically look up client records, review project status, check invoice details and read contract information. It can also carry out actions your team has allowed, such as drafting and creating an invoice, or updating a contract, based on a plain English request from a staff member.
Permissions and approvals keep people in charge. Access is set to the least privilege needed for each workflow, and consequential actions such as sending an invoice or changing a signed contract can require a human to approve them first. Activity can be logged so you can see what was done and when.
What you can automate
Client onboarding
When a new client signs up, Claude can gather the basic details, create the client record in Bonsai, and prepare the standard onboarding contract for review. A account manager checks the details and approves before anything is sent to the client, so new work starts quickly without errors creeping in during data entry.
Invoice creation and follow-up
At the end of a billing period, Claude can draft invoices from logged project hours or agreed milestones and present them for approval. Finance staff can ask Claude in plain language to find overdue invoices and prepare reminder messages, which helps small teams keep cash flowing without chasing each invoice by hand.
Project status updates
Project managers can ask Claude to summarise where each active project stands, which tasks are open and which deadlines are close. This gives account leads a clear picture across many clients at once, without opening each project in turn.
Contract amendments
When a client asks for a change in scope or rates, Claude can prepare a proposed amendment to the existing contract in Bonsai. A senior person reviews the wording and approves the change, reducing the time spent rewriting documents and keeping version records tidy.
Client records and CRM hygiene
Claude can help keep client details current by spotting duplicate records, missing contact fields and stale notes, then proposing corrections for a team member to confirm. Clean records make reporting and renewals far more reliable.
An end-to-end workflow: Client onboarding to first invoice
TriggerA signed proposal is marked as accepted in the sales pipeline.
Claude reads the accepted proposal details and creates the new client record in Bonsai.
Claude prepares the standard service contract with the agreed scope, rates and payment terms, and sends it to the account manager for approval.
After the contract is signed, Claude sets up the project and its first milestones in Bonsai.
Claude posts a summary to the team's Microsoft 365 channel and schedules the first invoice draft, which finance must approve before it is sent.
Claude logs each step so the team has a clear audit trail.
OutcomeNew clients move from signed proposal to active project and first invoice in a fraction of the usual time, with fewer data entry errors and clear human approval at every point that matters.

For teams in the US, UK, India and the Middle East
Organisations in the United States and the United Kingdom can host the Claude workflow in their chosen region to align with their own data handling rules. Indian businesses can design their setup to meet the Digital Personal Data Protection Act, 2023, with hosting in India where required. Organisations in the UAE and Saudi Arabia can follow the local data protection laws that apply to them, with hosting chosen to meet those requirements.

Frequently asked questions
What does the Bonsai MCP server do?
The Bonsai MCP server acts as a secure bridge between Claude and your Bonsai account. It lets Claude read and work with information such as clients, projects and invoices, and carry out actions your team has allowed. It does not give Claude access beyond the permissions you set, and it does not replace the Bonsai dashboard your team already uses.
Is it secure to connect Claude to Bonsai?
Security depends on how the connection is set up. We use least-privilege access, so Claude only reaches the functions a workflow needs. Sign-in uses the Basic method that Bonsai supports, consequential actions can require human approval, and activity is logged. We review the setup with your IT team before launch.
What can Claude do once it is connected to Bonsai?
Typically, Claude can look up client and project records, summarise status, check invoice details and read contracts. With approval, it can also draft and create invoices, set up client records and propose contract updates. The exact scope is agreed during design and limited to what your team needs.
How long does setup take?
Timing varies with the number of workflows and how many other systems are involved. A focused setup covering one or two workflows often takes a few weeks, including testing and training. We confirm a realistic timeline after the free automation audit, once we understand your requirements.
Which Bonsai plan or permissions do I need?
Generally, you need an active Bonsai account with the access level that covers the records and actions your workflows will use. Because plans and permission options can change, we confirm what your account supports during the free automation audit and set the connection up to match.
