Claude Agent SDK implementations that actually ship to production.
Production-grade Claude Agent SDK integrations built by senior engineers. Type-safe tool contracts, per-tenant secret isolation, observability from day one, and a deployment path that matches your security posture. £8K audit + fixed build.
What is Claude Agent SDK implementation?
The Claude Agent SDK is Anthropic's TypeScript + Python framework for building production agents on top of Claude. It handles the agentic loop (plan → tool call → observe → replan), the tool contract surface, session state, and the streaming boundary between your app and the Claude API. Empyreal Infotech builds custom Claude Agent SDK integrations that wire your internal systems (databases, ticketing, CRM, custom APIs, MCP servers) into an agent your team can actually operate. Every build ships with type-safe tool contracts (Zod or Pydantic), per-tenant secret isolation, structured logging on every tool call, and a deployment path (Docker, AWS Lambda, or your VPC) that matches your security posture.
What you get, every engagement.
Production agentic loops
Every agent ships with an explicit plan → act → observe loop, retry + timeout policies on every tool call, and a session-state layer that survives cold starts. No naive while-true loops. Guardrails on turn limits, token budgets, and tool-call fan-out from day one.
Tool contracts + type safety
Every tool the agent can call is defined in Zod (TypeScript) or Pydantic (Python) with runtime validation on both sides of the boundary. The agent literally cannot send a malformed payload to your database or CRM.
Observability + cost tracking
Structured logs on every turn: tool name, input, output, latency, token cost, calling tenant. Distributed traces wired to Sentry or Datadog. Per-tenant cost tracking so you can bill correctly and spot runaway loops before they hit your budget.
Deploy to where you already are
Docker for local dev, AWS Lambda for serverless prod, or your own VPC / Kubernetes for regulated data. Client credentials never leave your infra. We don't force a hosting choice on you.
The Claude Agent SDK implementation engagement, week by week.

Map the agent's job, inventory the tools it needs, threat-model the data boundary, pick the runtime (TypeScript or Python), and write six ADRs on the design including the escalation-to-human path.

Questions we get about Claude Agent SDK implementation, with real answers.
The Claude API is the raw HTTP endpoint you call to talk to Claude. The Claude Agent SDK is Anthropic's official framework that wraps the API with the agentic-loop machinery you'd otherwise write yourself: plan → tool call → observe → replan, session state, streaming, retries, and the tool contract surface. Both are supported. Building an agent directly on the API works — but the Agent SDK is what most 2026 production Claude agents ship on.
Yes — we've shipped Claude Agent SDK builds in both. TypeScript is the default when the surrounding stack is Node.js / Next.js / Cloudflare Workers. Python is the default when the agent needs to sit next to a Django, FastAPI, or ML pipeline. The audit week picks the runtime that costs your team least to operate.
Yes — Claude Agent SDK integrates natively with Model Context Protocol servers. See /mcp-server-development for the MCP-specific engagement page. If you need both the agent and the underlying MCP server, we scope them together in one audit.
Every agent build ships with an explicit session store (Redis or Postgres, per client preference) that persists conversation history, tool-call state, and per-tenant context between turns. Not a naive in-memory dict that dies on restart.
Every agent gets a per-tenant token-budget guardrail, a turn-limit cap, and a tool-call fan-out limit — all configurable per environment. Cost tracked per turn in structured logs. We've caught two 2026 runaway-loop incidents in staging before they hit production billing.
Anthropic has shipped meaningful Agent SDK updates every 4-8 weeks in 2026. Both TypeScript and Python SDKs. Contract tests catch the drift, we bump the SDK, re-run the conformance suite, and ship. If you're on the retainer we do this for you. If not, we send a 1-page migration note.
The £8K audit week + fixed build quote. Reference Claude Agent SDK builds we've shipped in 2026 land between £22K and £70K depending on the tool surface (3 tools vs 30 tools), the runtime (TypeScript vs Python), and the deployment target (single-tenant Lambda vs multi-region VPC). Retainer for SDK-drift + PR review is £5K/month.
Yes. Standard deploy targets are Docker (local dev), AWS Lambda (serverless prod), or your own Kubernetes / EC2 / VPC. For regulated data we default to VPC + private networking. Only the Claude API call itself egresses to Anthropic — your database, CRM, and business data stay behind your firewall.
