MCP server

The Model Context Protocol (MCP) is an open standard that defines how AI applications discover and call external tools. Any client that speaks MCP can talk to any server that speaks MCP.

The Plane MCP Server is a bridge that lets AI models interact with Plane. It exposes Plane's full API surface as MCP tools, so your AI tool can create work items, manage sprints, track time, and organise work without you leaving your editor or chat interface.

Transport modes

The server supports four transport modes. The right one depends on your deployment and usecase.

Transport	For	Auth method	How to start
HTTP with OAuth	Plane Cloud users, simplest setup	Browser-based OAuth flow	plane-mcp-server http
HTTP with PAT Token	Automated workflows, CI/CD	API key in request headers	plane-mcp-server http
Local Stdio	Local dev, self-hosted Plane	Environment variables	plane-mcp-server stdio
SSE (Legacy)	Existing integrations	Browser-based OAuth flow	plane-mcp-server http

Authentication model

The server has three authentication mechanisms, one per transport variant.

OAuth auth (HTTP with OAuth, SSE)

For cloud deployments, the server acts as an OAuth proxy to Plane's OAuth system:

1. The MCP client redirects the user to the Plane OAuth authorization page
2. The user logs into Plane and grants access
3. Plane returns an OAuth token which the server validates by calling /api/v1/users/me/
4. Subsequent MCP requests carry this token, from which the server extracts the workspace slug

The server supports OAuth redirect URIs for all major MCP clients: cursor://, vscode://, vscode-insiders://, windsurf://, claude://

Header auth (HTTP with PAT Token)

For automated workflows, the MCP client sends two headers with every request:

• x-api-key - a Plane API token
• x-workspace-slug - the workspace identifier

The server validates the API key against Plane's /api/v1/users/me/ endpoint on each request. No browser interaction required.

Environment variable auth (stdio)

For stdio mode, credentials are read from environment variables at startup:

• PLANE_API_KEY - your Plane API token
• PLANE_WORKSPACE_SLUG - your workspace identifier
• PLANE_BASE_URL - API URL for self-hosted instances (defaults to https://api.plane.so)

Identifier system

Plane uses two kinds of identifiers for work items.

• Readable identifier - human-friendly, e.g., ENG-42

  • Composed of the project identifier (ENG) and a sequence number (42)
  • Used in URLs, UI, and team communication

• UUID - machine-friendly, e.g., 3fa85f64-5717-4562-b3fc-2c963f66afa6

  • Used by all other tools for project_id, work_item_id, cycle_id, etc.
  • Returned by every API response

How-to guides

Plane hosts the MCP server for you at https://mcp.plane.so. If you run your own instance of the MCP server, replace https://mcp.plane.so with your own server's public URL (e.g., https://mcp.yourcompany.com) in all client config examples below.

Prerequisites

For all modes:

• A Plane account with access to at least one workspace

For stdio mode (local and self-hosted deployments)

• Python 3.10+ installed (python --version)
• uv package manager (recommended). See Installing uv

Get your API key (required for stdio and PAT token modes)

1. Open Plane and go to your workspace.
2. Generate a token. You can use either:
   • Personal Access Token - go to Profile Settings → API Tokens.
   • Workspace Access Token - go to Workspace Settings → Access Tokens.
3. Click Add access token, name it (e.g., "MCP Server"), click Generate token.
4. Copy the token as it will not be shown again.

Get your workspace slug

The slug is the short identifier in your Plane URL. For:

https://app.plane.so/acme-corp/

the slug is acme-corp.

Claude Desktop

Config file: /claude_desktop_config.json.

Quit Claude Desktop before editing, then relaunch and click the hammer icon (🔨) to confirm Plane tools are listed.

Stdio

Spawns the server as a local subprocess. Credentials come from environment variables.

{
  "mcpServers": {
    "plane": {
      "command": "uvx",
      "args": ["plane-mcp-server", "stdio"],
      "env": {
        "PLANE_API_KEY": "your_api_key_here",
        "PLANE_WORKSPACE_SLUG": "your-workspace-slug",
        "PLANE_BASE_URL": "https://plane.yourcompany.com"
      }
    }
  }
}

HTTP with OAuth

Connects to a remote MCP server. Claude Desktop opens a browser window for the Plane OAuth flow on first use.

{
  "mcpServers": {
    "plane": {
      "url": "https://mcp.plane.so/http/mcp",
      "type": "http"
    }
  }
}

HTTP with PAT Token

Connects to the PAT endpoint using API key headers. No browser interaction required - suitable for shared team setups where users authenticate via their own API key.

{
  "mcpServers": {
    "plane": {
      "url": "https://mcp.plane.so/http/api-key/mcp",
      "type": "http",
      "headers": {
        "x-api-key": "your_api_key_here",
        "x-workspace-slug": "your-workspace-slug"
      }
    }
  }
}

SSE (Legacy)

For existing integrations already using the SSE transport.

{
  "mcpServers": {
    "plane": {
      "url": "https://mcp.plane.so/sse",
      "type": "sse"
    }
  }
}

Open the AI panel (Cmd + Shift + A) to use Plane tools in conversation.

Self-hosted Plane deployments

Set PLANE_BASE_URL to the public URL of your Plane instance (e.g., https://plane.yourcompany.com). This is used for user-facing OAuth redirects and API calls in stdio mode.

In HTTP/SSE mode, the server also makes internal server-to-server calls to Plane for token validation. If your infrastructure routes internal traffic differently from public traffic (e.g., via a private network, service mesh, or internal load balancer), set PLANE_INTERNAL_BASE_URL to the internal address. When set, all server-to-server calls use this URL and only OAuth redirects use PLANE_BASE_URL.

If PLANE_INTERNAL_BASE_URL is not set, it falls back to PLANE_BASE_URL for all calls.

Before connecting a client, verify your credentials reach the instance:

curl -H "x-api-key: YOUR_API_KEY" \
  "https://plane.yourcompany.com/api/v1/users/me/"

A 200 response confirms the API key and URL are correct.

Common workflows

Look up a work item by ID

What is work item ENG-42 about?

Model calls retrieve_work_item_by_identifier with project_identifier="ENG" and work_item_identifier="42".

Create a work item

Create a high-priority bug in the ENG project called "Login times out on Safari".
Description: The OAuth callback redirects to a blank page on Safari 17+.
Assign it to me.

Model calls list_projects → retrieve_work_item_by_identifier (or get_me to resolve "me") → create_work_item.

Update work item state

Mark ENG-88 as done and add a comment: "Fixed in commit abc1234, needs QA."

Model resolves the UUID, calls list_states to find the Done state UUID, calls update_work_item and create_work_item_comment.

Sprint planning

Create a cycle called "Sprint 15" in ENG starting 2025-06-02, ending 2025-06-15.
Then move all incomplete issues from Sprint 14 into it.

Model calls create_cycle then list_cycles to find Sprint 14's UUID, then transfer_cycle_work_items.

Log time

Log 90 minutes on ENG-42: "Implemented retry logic for the upload endpoint."

Search across the workspace

Show me all high-priority bugs assigned to me that are still in progress.

Model calls list_work_items with filters priorities=["high"], state_groups=["started"], and the current user's UUID as assignee_ids.

Manage a module

Add ENG-55, ENG-56, and ENG-57 to the "Checkout Redesign" module.

Model calls list_modules to find the UUID, then add_work_items_to_module with the resolved work item UUIDs.

Troubleshooting

The server propagates errors from the Plane SDK as MCP tool errors.

Scenario	HTTP Status	Cause	Resolution
Invalid API key	401	PLANE_API_KEY is wrong or revoked	Regenerate the token in Plane settings
Invalid OAuth token	401	Token expired or revoked	Re-authorise through OAuth flow
Missing x-workspace-slug header	-	Header auth missing workspace	Include x-workspace-slug header
Wrong workspace slug	404	Slug doesn't exist	Check the exact slug in your Plane URL
Insufficient permissions	403	User role too low	Check your role in the workspace/project
Resource not found	404	UUID or identifier doesn't exist	Verify the ID; check if resource was deleted
Validation error	400	Required field missing or invalid value	Check required fields and value constraints
Redis unavailable	-	Token storage down	Set REDIS_HOST/REDIS_PORT or omit for in-memory
Network error	-	Cannot reach Plane API	Verify PLANE_BASE_URL and connectivity

Verify connectivity (stdio/PAT):

curl -H "x-api-key: YOUR_KEY" \
     "https://api.plane.so/api/v1/users/me/"

Run stdio mode manually to debug startup:

PLANE_API_KEY=your_key PLANE_WORKSPACE_SLUG=your-slug plane-mcp-server stdio

Test the HTTP server is running:

curl http://localhost:8211/http/mcp
# Should return MCP protocol response or 401
