What is the Planday MCP Server?

A Planday MCP server lets AI agents read and write Planday data through the Model Context Protocol — Anthropic's open standard for connecting LLMs to external tools. StackOne's Planday MCP server ships with 69 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.

Planday MCP Server FAQ

Planday MCP server vs direct API integration — what's the difference?

A Planday MCP server and direct API integration serve different use cases. Direct API integration is for software-to-software — backend code calling Planday. A Planday 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 Planday at runtime. StackOne provides both.

How does Planday authentication work for AI agents?

Planday 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 Planday account; StackOne handles token exchange, storage, and refresh. Credentials never reach the LLM, and each user is isolated via origin_owner_id.

Are Planday MCP tools vulnerable to prompt injection?

Yes — Planday 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 Planday agent and how do I avoid it?

Context bloat happens when Planday tool schemas and API responses eat your Planday agent's memory, preventing it from reasoning effectively. A single Planday 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 Planday agent can access?

Yes — you can limit which actions your Planday 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 Planday MCP server?

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

When should I NOT use a Planday MCP server?

Skip a Planday MCP server if your integration is purely software-to-software — direct Planday 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 Planday actions at runtime.

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

The StackOne Planday 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.
