MCP Servers

Custom Model Context Protocol servers that expose your systems to Claude, ChatGPT, Cursor, and any MCP-aware client.

Standardized tools and data for any agent

MCP is becoming the common interface between AI clients and your tools and data. We design, build, and deploy MCP servers that make your internal APIs, databases, and workflows usable from any MCP-aware agent — with auth, scoping, and audit baked in.

Outcomes

How we build it

Our approach.

01

Surface design

Decide what to expose: resources (read), tools (write), prompts (templates). Scoped to the right audience — internal, partner, or public.

02

Auth & isolation

OAuth, SSO, or scoped tokens. Per-user, per-tenant scoping. Rate limits and quotas so one client can't take the server down for everyone.

03

Deploy remote or local

Local stdio for Claude Desktop power users. Remote HTTP/SSE for teams and partners — on Lambda, Azure Functions, or Cloudflare Workers.

04

Version & observe

Every tool call is traced. Versioning contracts means clients don't break when you ship. Compatibility guarantees are explicit.

Capabilities

What you get.

Custom MCP server design for internal APIs and data
Resource, tool, and prompt surface modeling
OAuth / SSO / scoped tokens for secure access
Rate limiting, quotas, and per-user scoping
Deployment to AWS, Azure, GCP, or on-prem
Versioning and backward compatibility guarantees
Client integration with Claude Desktop, Cursor, and custom agents
What it looks like

Production-shaped, from day one.

server.ts
import { Server } from "@modelcontextprotocol/sdk/server"

const server = new Server({ name: "crm", version: "1.0.0" })

server.tool("search_accounts", {
  input: { query: "string", limit: "number?" },
  handler: async ({ query, limit = 10 }, ctx) => {
    ctx.requireScope("crm:read")
    const accounts = await crm.search(query, { limit })
    return { content: accounts }
  },
})

server.tool("update_account", {
  input: { id: "string", fields: "object" },
  requiresApproval: true,
  handler: async ({ id, fields }, ctx) => {
    ctx.requireScope("crm:write")
    return crm.update(id, fields)
  },
})
Architecture

A proven shape for this solution.

We adapt it to your cloud, data, and compliance requirements. Nothing here is boilerplate — every layer is justified by the numbers.

Common questions

What teams usually ask.

Why MCP instead of just building a REST API?

+

MCP is how agent clients (Claude Desktop, Cursor, custom agents) expect to discover and use tools. It gives you one standardized surface that works across clients and gets better as the ecosystem grows.

Is MCP ready for production?

+

For internal and partner use cases — yes, today. The spec is stabilizing quickly. We version contracts explicitly so upgrades don't break clients.

Can MCP servers be secured for multi-tenant use?

+

Yes — OAuth/SSO at the gateway, per-user scoping in the server, rate limits and quotas per tenant, and full audit logs on every tool call.
