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.

FAQ

Frequently Asked Questions

Common questions about this service.

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.

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.

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.

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.

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.

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.
