Works with Claude, ChatGPT, Cursor, and more

The Model Context Protocol standardizes how applications expose capabilities to LLMs. Instead of operating in isolation, your AI gains direct access to external platforms, live data, and real-world actions through secure, standardized connections.

This connection provides 3 powerful capabilities that interface natively with Claude, ChatGPT, Cursor, and other compatible AI platforms. No middleware. No custom integration required.

Debugging complex LLM pipelines feels like detective work.

Right now, when an agent fails in production, your team has to jump through hoops. You're copying run IDs from one dashboard, checking them against logs in a second system, and hoping you can manually stitch together what happened between the tool calls. It takes hours just to figure out if it was bad data input or a faulty model call.

With this MCP, your agent handles the detective work for you. You don't copy-paste IDs anymore; you simply query project metrics using langsmith_list_projects and then drill down with langsmith_get_run. It gives you one centralized view of what happened.

LangSmith MCP provides granular insights into every step.

The biggest time sink disappears when your agent uses langsmith_list_runs to give you a chronological list. You instantly see which steps succeeded, which failed, and how many tokens each part consumed—all without touching a single log file or dashboard tab.

This means you spend zero time gathering evidence and 100% of your time actually fixing the problem.

What your AI can actually do with this

When you're running LLMs or multi-step agents, the execution path can feel like a black box. LangSmith changes that. This connector gives your agent the ability to monitor and debug those tricky workflows in real time. You can look at an entire project's health, checking metrics like median latency or total runs across dozens of models.

If something goes wrong, you don't have to guess; you can get a full trace for any specific run, seeing every input and output. This whole system—listing projects, viewing recent activity, and getting detailed run reports—is all available through Vinkius, letting your AI client manage the complexity for you.

Questions you might have

How do I check overall performance with langsmith_list_projects? +

You use langsmith_list_projects to get a summary table. It shows aggregate metrics like median latency and total runs across your entire project group, letting you gauge overall health instantly.

What is the difference between langsmith_list_runs and langsmith_get_run? +

langsmith_list_runs gives you a list of recent attempts (the 'what'). langsmith_get_run requires a specific ID to give you the full, deep-dive trace that shows every single input and output from that run.

Can I use LangSmith MCP for simple logging? +

No. This MCP is built for tracing complex flows. If your task is just sending a message or updating one record, you don't need this; it handles the complexity of multi-step AI execution.

How do I track performance across my whole app? +

You start with langsmith_list_projects. This tool groups all your related traces and provides those aggregate metrics that let you compare project health at a glance.

How do I analyze the full details of a specific failed run using langsmith_get_run? +

It provides a complete, deep dive into that single execution. You'll see the entire trace flow, including all inputs and outputs, which lets you pinpoint exactly where the agent ran into an error or unexpected behavior.

Can I use langsmith_list_runs to filter traces by specific types, like only 'tool' calls? +

Yes. The tool lists runs and allows filtering by type (LLM, chain, or tool). This is useful because you can isolate the performance data for just one component of your larger agent workflow.

What does langsmith_list_projects show regarding project setup and scope? +

It gives a high-level dashboard view of all tracing projects in your account. You immediately get aggregate metrics like total runs, median latency, and feedback scores across entire groups of related traces.

How can I track token usage or specific performance timings using this MCP? +

Every run recorded by the MCP tracks these core metrics. You see both token counts and precise timing data for every step, whether it's an LLM call or a complex chain execution.

What is LangSmith and why do I need it? +

LangSmith is the 'Datadog for LLM applications'. Without observability, AI agents in production are black boxes — you can't see what they're doing, why they fail, or how much they cost. LangSmith traces every LLM call, chain execution, and tool use, giving you complete visibility into inputs, outputs, latency, token usage, and error rates.

Does LangSmith work only with LangChain? +

No! While LangSmith is built by the LangChain team and has native LangChain/LangGraph integration, it works with any LLM application. You can trace OpenAI, Anthropic, or any LLM provider directly using the REST API. It also integrates with CrewAI, AutoGen, and other frameworks.

How much does LangSmith cost? +

LangSmith offers a generous free tier with 5,000 traces per month — no credit card required. The Developer plan is $39/month with 50,000 traces. Enterprise plans include SSO, RBAC, dedicated support, and unlimited traces with volume discounts.
