Full read-write Claude connector for Vtiger CRM
Make Claude log activity and advance opportunities in Vtiger CRM
Stop clicking through Vtiger modules to update records by hand. Claude creates and updates contacts, leads, and opportunities, logs calls and to-dos against the right record, and advances a deal stage only once you approve, all where your CRM already keeps the data.
Vtiger CRM is a customer relationship management platform, available as a cloud product and a self-hosted open-source edition, where teams manage contacts, organizations, leads, opportunities, and cases. People want Claude to do more than read records: to update deals, log activity, and create records through its API.
What is a Vtiger CRM MCP server?
A Vtiger CRM MCP server is a small hosted service that exposes Vtiger CRM's data and actions to Claude over the Model Context Protocol, so Claude can manage contacts, deals, and pipeline inside your own account. We build it as a custom connector with separate read and write tools, and destructive actions stay gated behind your approval.
What can Vtiger CRM's current connector do today?
Today, Vtiger CRM does not appear to ship a first-party Claude or MCP connector, and any general integration is likely to lean toward reading records rather than writing them. A custom Vtiger connector adds scoped create and update actions over its REST API, with separated read and write tools and confirmation on the steps that change a pipeline or send anything outward.
What does full read-write Vtiger CRM access unlock?
Full read-write Vtiger access lets Claude create and update contacts, organizations, leads, and opportunities, advance an opportunity to the next sales stage, log calls, events, and to-dos, and move a case forward, all once you approve. The data entry that used to mean clicking through modules happens where your CRM already keeps it.
- Create or update a contact, organization, or lead from a conversation or email
- Advance an opportunity to the next sales stage and update its amount
- Convert a qualified lead into a contact and linked opportunity after you approve
- Log a call, event, or to-do against the right record
- Move a support case forward and reassign it to the right owner
- Find every record matching a query and propose batched field updates
Can Claude create and update records in Vtiger CRM?
Yes. Claude can create and update records in Vtiger CRM, including contacts, organizations, leads, and opportunities, over the REST API. It writes directly on the right record, and can convert a qualified lead into a contact and linked opportunity. Create and update flow freely, while gated steps wait for your approval.
Can Claude advance an opportunity through the pipeline in Vtiger CRM?
Claude can advance an opportunity to the next sales stage in Vtiger CRM and update its amount, but moving a deal through the pipeline is a gated write. Claude proposes the change and prepares the fields, and the stage only shifts after you confirm, so nothing in your pipeline moves by surprise.
Can Claude log calls and to-dos against records in Vtiger CRM?
Yes. Claude can log a call, event, or to-do against the right record in Vtiger CRM, and move a support case forward or reassign it to the right owner. It authenticates as a scoped Vtiger API user, so it never gets more access to your CRM than that account already has.
How a Vtiger CRM connector works
We build a small MCP server that authenticates to Vtiger with a scoped API user and access key over its REST API, using the narrowest permissions the work needs. Read tools (query records, fetch a record) and write tools (create, update, advance stage, log activity) are kept separate, and actions that change a pipeline or send anything outward require your confirmation. Claude never has more access than the Vtiger account it connects through, and for self-hosted instances we can restrict access by IP allowlisting.
