Short answer: a connector to one system usually costs between $1,500 and $5,000. A production server with several systems, OAuth sign-in, per-user permissions and audit logging usually costs between $5,000 and $15,000. Enterprise gateways go higher.
Typical market ranges
| Project | Typical range | Timeline |
|---|---|---|
| Single-system connector | $1,500 to $5,000 | 1 to 2 weeks |
| Multi-tool server with auth and scoping | $5,000 to $15,000 | 3 to 6 weeks |
| Enterprise MCP gateway | $15,000 to $40,000 | 1 to 3 months |
| Ongoing maintenance | $2,000 to $7,000 per month at agencies | monthly |
These ranges match public estimates from freelance marketplaces and agency price lists in 2026.
What drives the price
- Number of tools. Five tools are cheap. Fifty tools need design, testing and documentation.
- Write access. Reading is simple. Writing safely needs validation, confirmation and logging.
- Authentication. One service token is quick. Per-user OAuth with your roles takes longer.
- The API itself. Clean, documented APIs are fast. Legacy SOAP or undocumented endpoints are not.
- Hosting and compliance. Running inside your network or meeting audit rules adds work.

How to keep it down
Start with read-only tools for the five questions your team asks most. Add writes after a month of real use, when you know which ones matter.
