MCP Server Development Services
Custom Model Context Protocol servers that securely expose your enterprise systems to Claude — auth, tenancy, audit, rate limits, and a long-term maintenance posture engineered in from day one.
The short version
MCP server development is the production engineering work that lets Claude actually do useful work in your enterprise. Most demos of Anthropic MCP integration skip the parts that matter at scale — multi-tenant auth, per-action audit, rate-limit fairness, schema evolution, and the operational burden of keeping a server alive when the protocol itself is moving. NINtec ships custom MCP servers to clients across fintech, healthcare, logistics, and SaaS; our model context protocol development practice has built MCP servers exposing CRMs, billing systems, document repositories, internal APIs, and proprietary data warehouses. The deliverable is not a demo MCP server — it is a production-grade MCP server engineering artefact with a maintenance contract, observability dashboards, and a documented evolution path as the MCP specification matures.
What's in scope
MCP Server Architecture
Tool definitions, resource exposure, transport choice (stdio, SSE, or HTTP), error semantics, and timeout behaviour designed for the workload at hand.
Multi-Tenant Auth + Tenancy
Per-tenant credentials, scope-restricted tool access, row-level data filtering, and tenant-context propagation across tool calls.
Audit + Compliance Logging
Every tool invocation logged with caller identity, parameters, response, and latency. Logs retained per compliance regime; exportable to your SIEM.
Rate Limiting + Fairness
Per-tenant and per-tool rate limits, queue-based fairness, and back-pressure semantics that surface to the Claude client cleanly.
Schema Evolution Discipline
Versioned tool definitions, deprecation windows, and consumer-driven contracts so MCP server upgrades do not break the agents that depend on them.
Operational Runbooks
Incident-response runbooks, escalation paths, and a 24x7 on-call rotation where contractual SLA requires it.
How NINtec delivers
MCP server engagements typically run 8–14 weeks: 1 week of Discovery (which systems, which tools, which transport), 6–10 weeks of Build (production code, tests, observability), 1–3 weeks of Hardening (auth review, rate-limit drills, schema evolution rehearsal).

How an engagement runs
MCP Discovery
1 week
System inventory, tool surface design, transport selection, auth model, audit requirements, and a build plan with milestones.
Build + Iterate
6–10 weeks
Production MCP server delivered iteratively. Weekly demos with a working Claude client invoking the live server. Observability and audit logging integrated by week 3.
Hardening + Handover
1–3 weeks
Rate-limit drills, auth-review penetration testing, schema-evolution rehearsal, and operational handover to either client or NINtec ops.

MCP Server Development Services — FAQ
What is MCP and why do I need a custom server?
Model Context Protocol is Anthropic's standard for letting Claude invoke tools and access resources in external systems. Off-the-shelf MCP servers cover common SaaS platforms; custom MCP servers are what you need when Claude has to talk to your internal systems — your CRM, your data warehouse, your billing platform, your proprietary APIs.
How long does it take to build a custom MCP server?
A focused MCP server (3–8 tools against one system) ships in 6–8 weeks. A multi-system MCP server with tenancy and audit takes 10–14 weeks. Discovery and Hardening phases are non-negotiable on either end.
Stdio, SSE, or HTTP transport?
Stdio is for local agent processes (Claude Code, dev tooling). SSE (Server-Sent Events) is for long-lived sessions in browser or service-to-service. HTTP is the most flexible — request-response with optional streaming. The Discovery phase recommends one based on the deployment topology.
How do you handle multi-tenancy?
Per-tenant credentials enforced at the MCP server entry point, scope-restricted tool exposure (a tool may exist for one tenant but not another), and row-level data filtering enforced server-side. Tenant context is never trusted from the Claude client side — it is derived from the authenticated session.
What about audit logging?
Every MCP tool invocation generates a structured log entry with caller identity, parameters, response, latency, and outcome. Logs are exportable to your SIEM (Splunk, Datadog, Sumo, ELK) and retained per the compliance regime — typically 7 years for fintech, 6 years for HIPAA, longer for some pharma workloads.
Can the same MCP server be used by multiple Claude agents?
Yes — and this is the most common deployment pattern. A single MCP server exposes a stable tool surface; multiple Claude-driven agents (a customer-success copilot, an internal data-analyst agent, a sales-assist agent) consume from it. Versioning and deprecation discipline matters here.
How do you handle MCP specification evolution?
We track the Anthropic MCP spec and version our servers semver-style. Breaking changes get deprecation windows; non-breaking changes ship in minor versions. Consumer-driven contracts in CI catch accidental breaking changes before deploy.
What happens after the MCP server ships — who runs it?
Three options: client takes operational ownership, NINtec runs it on a managed-services retainer, or hybrid (client owns infra, NINtec owns updates). The choice is made at engagement start; most clients without an MCP-fluent SRE team pick managed services for the first 6–12 months while their team ramps.
Are NINtec's MCP servers reusable?
We have built reusable MCP server scaffolding (auth, audit, rate limiting, observability) that we license to clients indefinitely. The tool definitions and business logic are unique per client; the surrounding plumbing is reused.
