What is the Hive MCP Server?

A Hive MCP server lets AI agents read and write Hive data through the Model Context Protocol — Anthropic's open standard for connecting LLMs to external tools. StackOne's Hive MCP server ships with 29 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.

All Hive MCP Tools

Every action from Hive's API, ready for your agent. Create, read, update, and delete — scoped to exactly what you need.

Actions

Create Action
Create a new action (task) in Hive.
List Actions
Retrieve all actions (tasks) within a specific workspace.
Get Action
Retrieve a specific action (task) by its ID.
Update Action
Update an existing action's properties.
Delete Action
Delete an action (task) by its ID.

Action Comments

Create Action Comment
Add a new comment to a specific action.
List Action Comments
Retrieve all comments on a specific Hive action (task).

Unified Credentials

Get Unified Credentials
Return the authenticated identity and auth type for the current Hive connection. Hive has no /me endpoint; this action uses GET /workspaces as a lightweight auth probe and synthesizes a connection name from credentials.userId. auth_type is pinned to api_key (Hive is a single-auth connector).

Unified Groups

List Unified Groups
List Hive workspaces as IAM groups. Hive workspaces are the natural unit of grouping (containers for projects, actions, and members). type is pinned to workspace.
Get Unified Group
Retrieve a single Hive workspace by id, mapped to the IAM unified group schema, optionally expanding members.

Unified Organizations

List Unified Organizations
List the synthesized Hive organization. Hive has no /accounts or /tenants endpoint; this action returns a single synthetic organization with id "hive" so the IAM contract has a stable org node for cross-action joins.
Get Unified Organization
Retrieve the synthesized Hive organization. Hive has no /accounts or /tenants endpoint, so this action returns the single synthetic "hive" record when the id matches, or 404 otherwise.

Unified Roles

List Unified Roles
Return Hive's five documented workspace roles (External User, Member, Admin, System Admin, Restricted User). Hive's role-tags API exists but its response schema is undocumented, so this is a static catalog sourced from Hive's Help Center.
Get Unified Role
Retrieve one of Hive's five documented workspace roles (External User, Member, Admin, System Admin, Restricted User) by id, or 404 when the id matches none of them.

Unified Users

List Unified Users
List Hive workspace members mapped to the IAM unified user schema. When filter.group_id is provided, returns members of that workspace; when omitted, fans out across all workspaces the authenticated user can access and concatenates the membership lists. status is pinned to enabled; Hive's response schema for this endpoint documents no status field. roles are populated only when expand includes "roles".
Get Unified User
Retrieve a single Hive user by id. Hive has no /users/{id} endpoint; this action fans out across all workspaces accessible to the caller and filters the merged member list down to the requested id, returning 404 on a miss. roles are populated only when expand includes "roles".

Labels

Create Label
Create a new label in a Hive workspace.
List Labels
Retrieve all labels within a specific workspace.
Get Label
Retrieve a specific label within a workspace.
Update Label
Update an existing label's properties in a workspace.
Delete Label
Delete a label from a workspace.

Projects

Create Project
Create a new project in Hive.
List Projects
Retrieve all projects within a specific workspace.
Get Project
Retrieve a specific project by its ID.
Update Project
Update an existing project's properties.
Delete Project
Delete a project by its ID.

Workspaces

List Workspaces
Retrieve all workspaces accessible to the authenticated user.
Get Workspace
Retrieve a specific workspace by its ID.

Workspace Users

List Workspace Users
Retrieve all users belonging to a specific workspace.

Hive MCP Server FAQ

Does StackOne have a Hive MCP server?

Yes. StackOne offers a hosted Hive MCP server with 29 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.

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

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

How does Hive authentication work for AI agents?

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

Are Hive MCP tools vulnerable to prompt injection?

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

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

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

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

When should I NOT use a Hive MCP server?

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

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

The StackOne Hive 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.
