Agent-Ready Integrations | CloudWeld Services
Production-grade MCP servers and agent integrations for SaaS products: OAuth, tenant isolation, rate limits, and tool design that holds up in an enterprise security review.
MCP Servers & Agent Integrations
Put your product in Claude and ChatGPT. Properly.
We design, build, and harden MCP servers and agent integrations for SaaS products: real authentication, tenant isolation, rate limiting, and a tool surface tested against actual models, not just the demo.
THE PROBLEM
Why Most MCP Servers Never Reach Production
The ecosystem numbers are rough. Audits through 2026 found most public MCP servers abandoned, unauthenticated, or broken by spec changes. Generated servers demo well and then fail the first serious review.
No real authentication
Independent scans put the share of public MCP servers with no authentication at roughly 38 to 41 percent, and Microsoft measured OAuth adoption below 9 percent. An unauthenticated server wired into your product is an open API with extra steps.
Generated does not mean usable
Spec-to-server generators map every endpoint to a tool. A large API becomes hundreds of tools that overwhelm the model and burn the context window. Good tool design is editorial work: fewer, better tools shaped around what an agent actually does.
The spec keeps moving
MCP has shipped breaking changes roughly every six months since launch, including a major overhaul in mid-2026. One audit found over half of public servers effectively dead, many unable to connect to current clients. An integration is a commitment, not a one-off build.
Enterprise review kills the deal
The first serious customer who asks how your agent integration handles tenant isolation, rate limits, and audit logging will not accept "the generator handled it". This is exactly where deals stall.
Why Partner With Us
Integration Engineering, Not Tool Wrapping
Anyone can wrap an endpoint. The work that matters is auth, isolation, abuse resistance, and a tool surface that models use correctly.
Security review is the target
We build to pass the hardest review your customers will run: OAuth done right, least-privilege scopes, tenant isolation, rate limits, and audit logs.
Tool design for models
We design and test the tool surface against real models on real tasks, and cut whatever confuses them.
We track the spec
We follow MCP changes as they land and offer upkeep plans, so a protocol release does not silently break your integration.
We ship our own AI products
CloudWeld builds and runs its own AI products in production. The patterns we sell are the patterns we operate.
Our Process
From API to Agent-Ready
Design first, then build, then hardening against the ways agent integrations actually fail.
1
Scoping Call
A free 30-minute call: what should agents be able to do with your product, and is MCP, a ChatGPT app, or plain API work the right answer.
2
Design
The tool surface, the auth model, and the tenancy plan, written down with a fixed quote. Fewer, better tools beat a full endpoint dump every time.
3
Build
The server itself: OAuth flows, per-tenant scoping, rate limits, structured logging, and tests against real clients like Claude, ChatGPT, and Cursor.
4
Harden
We test against known attack patterns for agent tooling, including poisoned inputs and over-broad tool calls, and put guardrails on anything destructive.
5
Ship
Registry and directory submissions, customer-facing documentation, and a rollout plan.
6
Maintain
Optional upkeep plan: spec migrations, model behavior changes, and monitoring, so it still works next quarter.

FAQ
Frequently Asked Questions
Common questions about this service.
What does it cost?
Every integration is scoped on the call and quoted as a fixed price before we start, so there is no hourly meter and no surprise invoice. The number tracks your API surface, auth complexity, and tenancy model; most engagements start around $15,000. Ongoing upkeep plans start around $1,500 per month, or fold into a Fractional Platform Team retainer.
Can't we just generate one from our OpenAPI spec?
You can, and it makes a fine prototype. The generator vendors themselves document what their output skips: auth wiring, rate limits, and tool curation. We often start from generated output and spend the real time on exactly those parts.
MCP server, ChatGPT app, or both?
ChatGPT apps are built on MCP, so most of the work carries over. We usually build the MCP server first, verify it against Claude and other clients, then add the ChatGPT app layer if the audience justifies it.
What about prompt injection and tool poisoning?
Nobody can make an agent integration immune, and you should distrust anyone who claims otherwise. What we do is shrink the blast radius: least-privilege scopes, confirmation gates on destructive actions, input and output filtering, and audit logs so you can reconstruct what happened.
Who hosts and owns it?
You do. It runs on your infrastructure under your accounts, and the code lives in your repo. We set it up so you can operate it without us.
A spec update broke our existing server. Can you fix just that?
Yes. Spec migrations are a common standalone job, usually one to two weeks. We also leave you on a version strategy that makes the next update less painful.
Do you build internal MCP servers too?
Yes. Wiring internal tools and data to Claude or other assistants for your own team is the same discipline, with SSO and internal permissions instead of customer-facing OAuth.
