About us

Who builds custom Claude connectors?

Custom Connectors is the done-for-you team behind these MCP connectors. We build, host, and maintain full read-and-write connectors so Claude can act inside any software a business runs. We own the hard parts: OAuth, hosting, write safety, and ongoing maintenance, so your team simply uses Claude.

What does Custom Connectors do?

Custom Connectors builds, hosts, and maintains custom MCP connectors that give Claude full read-and-write access to the tools you already run. Where nothing exists we build one. Where a connector is limited or read-only, we build a deeper one. We operate it so you never run an MCP server yourself.

A connector is only useful if it keeps working in production. That is why our service is not a one-time handoff. We scope the tool and the write actions with you, build and host the connector, and then stay responsible for it as your software and its API change over time.

What does it mean that you own the hard parts?

Owning the hard parts means we take on the work that usually stops a team from using Claude inside their software: building the connector, hosting it, handling OAuth and on-prem access, and maintaining it as things change. You get a working connector, not a project to staff.

We build it

We design and write the MCP connector for your specific tool: separate read and write tools, scoped permissions, and confirmation gates on the actions that matter.

We host it

The connector runs on infrastructure we operate, including the OAuth flow and, for on-prem systems, firewall and IP allowlisting. You do not run an MCP server.

We maintain it

When your software's API or schema changes, or tokens need to rotate, we fix it. The connector keeps working without your team chasing it.

Why trust us with write access to your software?

Trusting us with write access is safe because the connector never grants Claude more access than your account already has. Read and write tools are separated, and destructive or outbound actions are gated behind a confirmation you control, so write power is scoped rather than open-ended.

Never more access than your account has

A connector authenticates as your account and inherits the permissions that account already has. It cannot reach anything you could not reach yourself.

Write actions are scoped, not wide open

Create and update flow freely so work moves forward. Destructive or outbound actions like delete and send are gated behind a human-in-the-loop confirmation you control.

It acts only inside a conversation you start

The connector does nothing on its own. It runs when you ask Claude to do something in a conversation you opened, and only the tools we scoped are available.

Who is behind Custom Connectors?

Custom Connectors is built and run by the people who write the connectors. We work in MCP, OAuth, and production APIs every day, and we started this because the hardest part of putting Claude to work inside a real business is not the prompting, it is the plumbing: a connector that reads and writes the right data, holds the right permissions, and keeps working when a vendor changes an API.

We keep it deliberately hands-on. Whoever scopes your connector is also building, hosting, and maintaining it, so nothing is lost in a handoff between a promise on a call and the code that has to deliver it.

Frequently asked questions

Who builds custom Claude connectors?

Custom Connectors builds them as a done-for-you service. We design, host, and maintain full read-and-write MCP connectors for any software a business runs, so a non-technical team can use Claude inside their tools. You do not build, deploy, or operate an MCP server. We own those hard parts.

Why should I trust you with write access to my systems?

Because the connector never grants Claude more access than your account already has, and the actions that could cause harm are gated. Create and update flow freely, while delete and send require a human-in-the-loop confirmation you control. The connector also acts only inside a Claude conversation you start.

Do you actually maintain the connector after it ships?

Yes. Maintenance is the point of working with us rather than commissioning a one-off build. When a vendor changes an API, alters a schema, or rotates auth requirements, we update the connector so it keeps working. Ongoing maintenance and support are a defined part of the engagement.

What kind of software can you build connectors for?

Any software in your stack. Mainstream SaaS, industry-specific tools, and bespoke in-house or on-prem systems that appear in no connector directory. If a tool already has a limited or read-only connection, we build a deeper read-and-write one and support what we ship.
