What is the Lattice MCP Server?

A Lattice MCP server lets AI agents read and write Lattice data through the Model Context Protocol, Anthropic's open standard for connecting LLMs to external tools. StackOne's Lattice MCP server ships with 40 pre-built actions, fully extensible via the Connector Builder, plus managed authentication, prompt injection defense, observability, and agent execution runtime. Connect it from MCP clients like Claude Desktop, Claude Code, Cursor, Goose, and VS Code, or from agent frameworks like OpenAI Agents SDK, LangChain, and Vercel AI SDK.

Lattice MCP Server FAQ

Does StackOne have a Lattice MCP server?

Yes. StackOne offers a managed Lattice MCP server with 40 pre-built actions, and every action is tested and QA'd by StackOne. Connect it to Claude, Cursor, and any other MCP client, or to any agent framework through the AI Action SDK. It ships with managed agent authentication, prompt injection defense, and tool discovery with server-side execution that preserve your agent's context window and keep reasoning performance.

Lattice MCP server vs direct API integration: what's the difference?

A Lattice MCP server and direct API integration serve different use cases. Direct API integration is for software-to-software work, where backend code calls Lattice. A Lattice MCP server is for AI agents that discover and call Lattice at runtime, such as MCP clients like Claude and Cursor, plus framework agents built with OpenAI, LangChain, or Vercel AI. StackOne provides both.

How does Lattice authentication work for AI agents?

Lattice authentication for AI agents works through a StackOne Connect Session. Create one via the dashboard or the SDK to get an auth link and ready-to-paste config for Claude Desktop, Cursor, and other MCP clients. Your user authenticates their own Lattice account; StackOne handles token exchange, storage, and refresh. Credentials never reach the LLM, and each user is isolated via origin_owner_id.

Are Lattice MCP tools vulnerable to prompt injection?

Yes. Lattice MCP tools can be vulnerable to indirect prompt injection. Any tool that reads user-written content, such as documents, messages, tickets, records, or free-text fields, is a potential vector. StackOne Defender scans every tool response before it enters the agent's context. It runs regex patterns in ~1ms, then a MiniLM classifier in ~4ms. Accuracy is 88.7%, and it runs entirely on CPU.

What is the context bloat of a Lattice agent and how do I avoid it?

Context bloat happens when Lattice tool schemas and API responses eat your Lattice agent's memory, preventing it from reasoning effectively. A single Lattice query can return a massive JSON response, and connecting multiple tools compounds the problem. Tools Discovery reduces it by loading only the tools relevant to each query.

Can I limit which actions my Lattice agent can access?

Yes. You can limit which actions your Lattice agent can access directly from the StackOne dashboard. Toggle actions on or off, or restrict them to specific accounts, with no code changes to your agent. Session tokens can be scoped to exact actions so if one leaks, exposure stays contained.

Can I create custom agent actions for my Lattice MCP server?

Yes. You can create custom agent actions for your Lattice MCP server using Connector Builder. It's an integration agent your coding assistant (Claude Code, Cursor, or Copilot) can invoke to research Lattice's API, generate production-ready connector YAML, test against the live API, and validate before you ship.

When should I NOT use a Lattice MCP server?

Skip a Lattice MCP server if your integration is purely software-to-software, because direct Lattice API integration is simpler when no AI agent is involved. For deterministic, compliance-critical operations (financial transactions, regulatory reporting), direct API gives you predictable behavior without agent-driven decision-making. MCP shines when AI agents need to dynamically discover and call Lattice actions at runtime.

What AI frameworks and AI clients does the StackOne Lattice MCP server support?

The StackOne Lattice MCP server supports both. MCP clients (paste-and-go apps): Claude Desktop, Claude Code, Cursor, VS Code, Goose. Agent frameworks (code SDKs you build with): OpenAI Agents SDK, Anthropic, Vercel AI, Google ADK, CrewAI, Pydantic AI, LangChain, LangGraph, Azure AI Foundry.
