Done-for-you custom MCP connectors
Put Claude to work inside the tools you already run
We build Claude a full read-and-write connector to the software you run, with your approval on anything destructive, then host and maintain it. Stop paying people to move data between your tools.
Most builds go live in about two weeks, and you pay only when it works. We host and maintain it. No call required.

Custom Connectors builds full read-and-write custom MCP connectors so Claude can act inside the software you already run. We cover any tool in your stack, whether it has no connector yet or a built-in one that only covers the basics, at a non-enterprise price.
Connectors for the software teams actually run
Two situations, one fix
You already know the tool you want Claude working inside. What is stopping you is almost always one of these. We build the connector either way.
Your software has no connector
Proprietary, custom, or in-house systems that are not in any directory and never will be. We build one specifically for your system, including on-prem apps behind a firewall.
Your connector falls short
A directory or third-party connector exists, but it is read-only, shallow, or poorly supported. We build a deeper one with real read-write, and we support what we ship.
What it looks like in Claude
You ask in plain language. Claude takes the actions inside your tools, and waits for your approval on anything destructive.
It acts inside one tool
Draft, update, create, archive. The change lands in the tool itself, not as text you copy and paste.
Draft a reply to Arlene in this thread and clear the rest of my inbox.
Drafted your reply in the thread and archived 4 read messages.
Approval needed

One ask, across your stack
Ask once, and Claude works across every tool the job touches, in a single turn.
The Acme deal just closed. Post a summary to #wins and draft the invoice.
Posted the win to #wins and drafted the invoice in QuickBooks for your review.
Connectors done right
Any software, not a fixed catalog
Mainstream SaaS, industry-specific tools, or a bespoke in-house system. If it is in your stack, we build a connector for it. No 'sorry, that is not supported.'
The full capability, not a partial tool set
Built-in connectors ship a fixed, generic set of tools. We build the specific actions, fields, and workflows yours leaves out, with scoped, human-in-the-loop controls on destructive steps.
We close the gaps built-in connectors leave
Native connectors are common now, but they stop at the basics. The built-in Gmail connector drafts a reply as a new message; we make it draft inside the original thread. We build deeper and support what we ship.
We own the hard parts
OAuth lifecycle, firewall and IP allowlisting for on-prem systems, schema changes when your software updates, and ongoing maintenance. Handled.
How it works
Scope
You pick your tool and what Claude should do in the build form, including which write actions need your approval. No call required.
Build
We build and host a custom MCP connector with separated read and write tools, OAuth, and scoped permissions.
Use
You use Claude in your day-to-day. We maintain the connector as your software and its API change.
What full read-write unlocks
In-thread Gmail drafting that native connections do not offer
A team wanted Claude to draft replies inside the original email thread, not beside it. We built full read-write Gmail with in-thread drafting, labels, and gated send.
Replies drafted in-thread, every send gated for review
Full read-write into a custom Pipedrive setup
Beyond the directory connector: Claude creates and updates deals, activities, and custom fields across a heavily customized pipeline.
Deals and custom fields updated without leaving the chat
A connector for a bespoke internal referral portal
An in-house referral application with no directory listing. We built a connector so Claude can read and write referrals directly.
Referrals read and written with no manual re-keying
Built so you can trust Claude with production systems
Scoped write controls
Read and write tools are separate. Delete and send are gated behind a confirmation you control.
OAuth and permissions
Connectors authenticate as your account and inherit your existing permissions. Never more access than you have.
Maintained over time
We handle API changes, schema updates, and the OAuth lifecycle so the connector keeps working.
Pricing
Custom integration without the enterprise integration price tag. A one-time build fee, volume pricing for multiple connectors, and a monthly fee to keep everything running.

Your risk is covered
The Pay-When-It-Works Guarantee
We scope the exact actions Claude will run in your tools, in writing, before we build. You watch it work live in your own account before you pay the balance. If it does not do what we agreed, we fix it on our clock, or you walk and owe nothing for the build.
The Stay-Live Guarantee
While you are on maintenance, if a vendor update ever breaks your connector and we have not restored it within two business days, that month is on us.
We take on a limited number of builds each month so every connector is built right and supported. If this month is full, we will tell you the next opening.
