Anthropic · Claude agents, Skills, MCP and training Claude, end to end: agents, Skills, MCP and training.

We build deeply on Anthropic’s Claude: accountable AI co-workers and delegating subagents, on-demand Agent Skills, and custom MCP servers wired to your own systems — engineered on the Claude Agent SDK, governed from day one. And we train your own teams to build with Claude: bespoke, in-house, on your work, in Kolkata, Mumbai or online across India.

Why it matters

An agent is only as good as its tools and guardrails.

Capability where it pays; governance from the first line.

  1. 01A chatbot bolted onto a workflow does not finish the work. Agents need to research, build, evaluate, deploy and govern, with humans in the loop where it counts.
  2. 02A general-purpose agent that carries every specialist instruction in context all the time is slow, expensive and easily confused.
  3. 03Off-the-shelf integrations cover commodity tools, not the systems that encode your business — CRM views, billing APIs, internal services and domain models.
  4. 04Agentic autonomy without governance is a liability. Every tool call needs scoped access, allow-lists and an audit trail.

What we engineer

One human directing many accountable agents.

We build deeply on Claude for long-horizon reasoning, reliable tool use and the open Model Context Protocol (MCP) standard. Our default agentic stack is Claude, the Claude Agent SDK and MCP — connected to your real systems, while staying model-agnostic (bring your own model, or BYOM).

AI co-workers

A team of Claude-powered agents directed by a single human. Each agent is accountable for its slice of the job, with human-in-the-loop guardrails at approvals, destructive actions and external side effects.

Subagents

A lead agent delegates independent sub-tasks to separate agents, each with its own context window and tools, and only their conclusions return. Subagents can run on cheaper, faster models such as Haiku 4.5, and a fresh-context verifier subagent catches more than self-review.

Agent Skills

Reusable, filesystem-based capability packages — a folder with a SKILL.md — loaded on demand through progressive disclosure. We package your recurring, well-specified workflows as Skills: consistent, versioned and reusable across every agent.

Custom MCP servers

Servers for the systems that encode your business, exposing Tools, Resources and Prompts through one discoverable, model-agnostic interface — each with scoped credentials per consumer, allow-lists and audit logging on every invocation.

Adaptive thinking and effort control

Claude decides how much to reason at each step. We tune the trade-off between effort, cost and quality per route, rather than paying for maximum reasoning everywhere.

Prompt caching

Stable context is cached across turns, so long-running agents pay only for what changes — not for re-reading the same preamble on every request.

How we build

Agent SDK and tool use, with the loop under control.

You define your own tools; the Anthropic SDK’s tool runner drives the agentic loop — calling the model, executing the tool, feeding results back and repeating until the work is done.

  1. / 01

    Tool runner for autonomy

    For flows we want to run end to end, the tool runner handles the loop automatically.

  2. / 02

    Manual loop for control

    Where a step needs an approval gate or human confirmation, we write the loop by hand and stop for sign-off before any hard-to-reverse action.

  3. / 03

    Effort and adaptive thinking

    We tune reasoning depth per route to balance cost and quality — higher effort where correctness matters, lower where speed does.

  4. / 04

    Prompt caching

    A frozen system prompt and a deterministic tool set keep the cache warm, so long agent runs stay efficient.

  5. / 05

    Traced, logged, scored

    Our Agent Evaluations practice scores every agent loop and every LLM invocation on correctness, completeness, safety and tool-call effectiveness.

Claude training · Kolkata and India

Claude training written for your organisation.

No open courses and no generic syllabus. Every cohort is written for one organisation — your industry, your regulatory reality, your systems and the work your teams do each week — and scoped the way you need it: organisation-wide, one department at a time, or a single process taken end to end. Delivered on-site in Kolkata and Mumbai, or live online for teams anywhere in India, always on your own workflows, repositories and data.

What you get

Agents that finish the work and leave an audit trail.

  • A team of Claude co-workers directed by one human

  • Subagents for parallel and independent workstreams

  • Your recurring workflows packaged as versioned Agent Skills

  • Custom MCP servers with scoped credentials and allow-lists

Where it fits

Governed from the first line.

Every agent loop runs under our Responsible AI and Zero Trust posture, and our Agent Evaluations practice produces and evaluates the evidence. It pairs naturally with the GenAI Delivery Factory for production rollout, and with Future of Work for teams of human and AI co-workers.

FAQ

Frequently asked.

01What is custom MCP development?

Building Model Context Protocol servers for your own systems — CRM, billing, internal APIs, domain models — rather than relying only on off-the-shelf servers. An MCP server exposes tools, resources and prompts through one discoverable, model-agnostic interface. We build each one with scoped credentials, allow-lists and audit logging, so an agent gets exactly the access it needs and nothing more.

02What are Claude Agent Skills?

Reusable, filesystem-based capability packages — a folder with a SKILL.md — that load on demand through progressive disclosure. The skill’s short description sits in context; the full instructions load only when the task calls for them. That turns a general Claude agent into a specialist without bloating its context or cost.

03What are Claude subagents?

Subagents let a lead Claude agent delegate independent sub-tasks to separate agents, each in its own context window, so only their conclusions return to the lead. In Claude Code they run as distinct agent types (a read-only Explore agent, or custom agents under .claude/agents/), spawned in parallel. On the Claude Agent SDK and Managed Agents, a coordinator delegates to a roster of agents in context-isolated threads, one level deep. Subagents can run on cheaper Claude models such as Haiku 4.5 to control cost, and suit parallel or independent workstreams better than tightly sequential steps.

04Do you offer Claude training in Kolkata?

Yes — as bespoke, in-house training for one organisation at a time, on-site in Kolkata and Mumbai or live online for teams anywhere in India. We do not run open courses or a fixed syllabus. You choose the scope: an organisation-wide rollout, a single department such as procurement, finance or engineering, or one process taken end to end — tender evaluation, claims handling, month-end close. Before a cohort we sit with your teams to learn that work, the systems behind it and the regulatory constraints of your sector, then write the exercises against your own workflows, repositories and data. Tracks span business teams, engineers, Agent Skills and subagents, custom MCP development, and a briefing for leaders, each taught by engineers who build and govern agentic systems in production.

05What does your Claude Code and MCP training cover?

The engineering track is built around your codebase, not a sample project: Claude Code working inside your own repositories, with the prompting and review habits that suit your stack and review process. From there teams package the workflows they repeat every week as versioned Agent Skills, learn when to delegate to subagents, and build a custom MCP server for one of your internal systems with scoped credentials, allow-lists and audit logging. Teams leave with working artefacts of their own, not slides.

06Which Claude model should we use?

It depends on the task: Claude Opus 5 (1M context) for demanding agentic work; Claude Sonnet 5 for the best balance of speed and intelligence; Claude Haiku 4.5 for fast, cost-effective and subagent work; and Claude Fable 5.1 for the hardest long-horizon problems. We are model-agnostic (BYOM) and often route different steps of one loop to different tiers.
