LangChain Agent Capabilities

Leverage the LangChain ecosystem for flexible, production-ready AI agent architectures

LangChain Tools & Chains

Build custom tool integrations and chain complex operations together. From API connectors and database queries to web scrapers and calculators — we create tools that your agent calls autonomously to complete tasks.

LangGraph Stateful Workflows

Design complex, stateful agent workflows using LangGraph's graph-based orchestration. Implement conditional branching, parallel execution, human-in-the-loop checkpoints, and persistent state across multi-step agent interactions.

Memory Management

Implement sophisticated memory strategies — buffer memory for recent context, summary memory for long conversations, vector memory for semantic recall, and entity memory for tracking key information across sessions.

LangSmith Tracing & Evaluation

Full observability with LangSmith for production monitoring. Trace every LLM call, tool execution, and chain step. Run automated evaluations, track regression, and debug issues with detailed run histories.

Multi-Model Support

Swap LLMs without rewriting your agent. LangChain's model abstraction lets you switch between OpenAI, Anthropic, Google, Mistral, and open-source models seamlessly — optimizing for cost, speed, or capability per task.

Custom Tool Development

Build domain-specific tools that extend your agent's capabilities. From Salesforce integrations and Jira automation to custom ML model inference and proprietary API connectors — all wrapped in LangChain's tool interface.

Our LangChain Agent Development Process

A proven 5-step process from requirements to production LangChain deployment

Discovery & Architecture
We map your workflows, define the agent graph topology using LangGraph, select the optimal LLM provider for each task, and plan tool integrations, memory strategy, and observability setup with LangSmith.
Prompt Engineering & Prototyping
Craft agent system prompts, build custom tools, define LangGraph state schemas, and deliver a working prototype with LangSmith tracing enabled — so you can see exactly how your agent thinks and acts.
Integration & Development
Connect tools to your APIs and databases, implement memory persistence, build LangGraph workflows with error handling and human-in-the-loop checkpoints, and optimize chain execution for production throughput.
Testing & Evaluation
Run automated evaluations via LangSmith with custom scoring functions. Test tool call accuracy, response quality, memory recall, and edge cases across hundreds of scenarios. Track regressions with evaluation datasets.
Deployment & Monitoring
Production deployment with LangSmith dashboards, cost tracking per chain, tool call analytics, latency monitoring, and alerting. Continuous improvement through feedback loops and automated evaluation pipelines.

What Our Clients Say

"Edesy built a LangGraph-powered research agent that automates our competitive intelligence workflow. It searches the web, analyzes documents, and generates structured reports. What took our team 8 hours per company now takes 15 minutes with 90% accuracy."

VO

VP of Strategy

Strategy at Management Consulting Firm

"The LangChain agent they built handles our entire customer onboarding flow — it verifies documents, runs KYC checks, updates our database, and sends welcome emails. LangSmith tracing helped us debug and optimize every step. Onboarding time dropped from 3 days to 4 hours."

HO

Head of Product

Product at FinTech Platform

"We needed an agent that works with multiple LLMs — GPT-4o for reasoning, Claude for document analysis, and a fine-tuned Llama model for classification. LangChain's abstractions made this seamless, and swapping models takes one config change. Saved us months of custom integration work."
