A Humaans MCP server lets AI agents read and write Humaans data through the Model Context Protocol — Anthropic's open standard for connecting LLMs to external tools. StackOne's Humaans MCP server ships with 117 pre-built actions, fully extensible via the Connector Builder — plus managed authentication, prompt injection defense, and optimized agent context. Connect it from MCP clients like Claude Desktop, Cursor, and VS Code, or from agent frameworks like OpenAI Agents SDK, LangChain, and Vercel AI SDK.

MCP Code Mode: Keeping Tool Responses Out of Agent Context
Anthropic's code_execution processes data already in context. Custom MCP code mode keeps raw tool responses in a sandbox. 14K tokens vs 500.

Indirect Prompt Injection Defense for MCP Tools: A Technical Guide

Humaans MCP Server FAQ
Humaans MCP server vs direct API integration — what's the difference?
A Humaans MCP server and direct API integration serve different use cases. Direct API integration is for software-to-software — backend code calling Humaans. A Humaans MCP server is for AI agents — MCP clients like Claude and Cursor, plus framework agents built with OpenAI, LangChain, or Vercel AI — discovering and calling Humaans at runtime. StackOne provides both.
How does Humaans authentication work for AI agents?
Humaans authentication for AI agents works through a StackOne Connect Session. Create one via the dashboard or the SDK — you get an auth link and ready-to-paste config for Claude Desktop, Cursor, and other MCP clients. Your user authenticates their own Humaans account; StackOne handles token exchange, storage, and refresh. Credentials never reach the LLM, and each user is isolated via
origin_owner_id.Are Humaans MCP tools vulnerable to prompt injection?
Yes — Humaans MCP tools can be vulnerable to indirect prompt injection. Any tool that reads user-written content — 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 — regex patterns in ~1ms, then a MiniLM classifier in ~4ms. 88.7% accuracy, CPU-only.
What is the context bloat of a Humaans agent and how do I avoid it?
Context bloat happens when Humaans tool schemas and API responses eat your Humaans agent's memory, preventing it from reasoning effectively. A single Humaans query can return a massive JSON response, and connecting multiple tools compounds the problem. Tools Discovery and Code Mode reduce context bloat — loading only relevant tools per query and keeping raw responses out of the agent's context.
Can I limit which actions my Humaans agent can access?
Yes — you can limit which actions your Humaans 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 Humaans MCP server?
Yes — you can create custom agent actions for your Humaans MCP server using Connector Builder. It's an integration agent your coding assistant (Claude Code, Cursor, or Copilot) can invoke to research Humaans's API, generate production-ready connector YAML, test against the live API, and validate before you ship.
When should I NOT use a Humaans MCP server?
Skip a Humaans MCP server if your integration is purely software-to-software — direct Humaans 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 Humaans actions at runtime.
What AI frameworks and AI clients does the StackOne Humaans MCP server support?
The StackOne Humaans 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.
