MCP Server Development

Model Context Protocol servers giving AI agents typed, scoped access to your systems.

An MCP server is the contract between an AI agent and a system you would never hand it unsupervised. I build them as I have built integrations since 2022: typed inputs, scoped credentials, bounded responses, an audit trail.

Most MCP servers fail for one reason: someone exposed forty tools and an admin credential to a language model and called it an integration.

TL;DR

  • The Model Context Protocol is an open standard for exposing tools and resources to AI agents.
  • An MCP server wraps a system you own — a CRM, a database, an internal API — as typed tools.
  • Transport is a deployment choice: stdio for a local client, streamable HTTP for a shared server.
  • No shipped MCP server appears in my portfolio. This page is capability framing, and it says so.

The challenge

Teams wire an agent into a live system with a broad API key and a long tool list. Then the model calls the wrong one, the response overflows the context window, and the logs explain nothing.

What I build

MCP Server Build

Production server over your database, internal API, or SaaS account

Tool & Resource Design

Choosing what to expose and what to withhold

Auth & Scoping

Per-connection credentials, read/write separation, gates before irreversible actions

Transport & Deployment

stdio for local clients; streamable HTTP behind TLS and an identity provider

Agent & Client Wiring

Connecting the server to Claude, OpenAI-based agents, or your orchestrator

Hardening & Observability

Response caps, pagination, rate limiting, and audit logs

What is an MCP server, and why would I need one?

MCP is an open protocol letting an AI agent discover and call capabilities from an external system through one interface. An MCP server publishes those capabilities. You need one when an agent must read or change data in a system you own, with access typed, scoped, and logged.

Without a protocol, every agent integration is bespoke: a tool schema written for one framework, then rewritten for the next. MCP moves that contract into the server.

stdio or HTTP — which transport should my server use?

Use stdio when server and client share a machine: a local developer tool, a desktop assistant, anything touching local files. Use streamable HTTP when several people share one server, when it lives in your cloud, or when access sits behind an identity provider.

A stdio server is a process the client launches, with no network surface to defend. An HTTP server needs TLS, auth, rate limiting, searchable logs.

How do you stop an agent doing damage through your tools?

Scope the credential, not the prompt. Each tool gets the narrowest permission that lets it work, destructive operations stay separate from reads, every input is schema-validated before it reaches your system, and anything irreversible needs a confirmation step or is not exposed at all.

The failure modes repeat: over-broad tool surfaces that confuse the model, unscoped credentials that turn prompt injection into a breach, and payloads that blow the context window.

You have not shipped an MCP server. Why hire you?

Because an MCP server is a typed adapter over a system, and adapters are most of what I have built since 2022: a HIPAA HL7 gateway, eight CMS adapters behind one publishing interface, four registry APIs behind one marketplace. The protocol is the new part.

If you need an MCP server already in production, that is a fair filter. If you want someone who has handled rate limits, partial failures, and credential rotation, the work below is the evidence.

How we work

Most MVPs ship in 3–6 weeks; complex platforms are scoped individually once the requirements are clear.

01

Intro Call

A 30-minute conversation about your project, goals, and timeline. No commitment either way.

02

Scoped Proposal

A written scope, architecture outline, and quote. I respond to every message within 24 hours.

03

Weekly Demos

You see working software every week, with written progress updates in between. No black boxes.

04

Ship & Handover

Deployment, documentation, and a clean handover — you own everything I build.

Frequently asked questions

Do you have a shipped MCP server I can look at?
No, and I would rather say so than dress up something adjacent. No project on this site uses the Model Context Protocol. What I can show is the layer beneath it: an HL7/FHIR gateway moving 10,000+ clinical messages a day at 99% delivery.
How long does building an MCP server take?
A focused server over one system — a database, an internal API, one SaaS account — is a short, well-scoped engagement. Anything spanning several backends, OAuth, or writes that move money is scoped individually. For reference on larger builds, MVPs typically take 3–6 weeks.
Can an MCP server connect an agent to HubSpot or Salesforce?
Yes — that is the main reason teams ask for one. I have shipped a HubSpot CRM integration in production for a sales platform used by 50+ reps. Salesforce I can build against, but no Salesforce project exists here, so treat it as capability.
What are the most common ways MCP servers go wrong?
Three, repeatedly. Over-broad tool surfaces, where forty near-identical tools make the model pick badly. Unscoped credentials, where one connection reads everything and a prompt injection becomes a breach. And unbounded responses, where a single query consumes the whole context window.
What does an MCP engagement cost?
Most engagements start around $5K; smaller well-scoped work is considered case-by-case. Post-launch support is available once the server is live. Send over the system an agent needs to reach and what it should be allowed to do, and you will have a reply within 24 hours.
