This guide is for teams that want to run their own instance of the Plane MCP server — either because they use a
self-hosted Plane installation that needs OAuth against their own domain, or because they want full control over the
MCP infrastructure.

If you're a Plane Cloud user connecting to `mcp.plane.so`, you don't need this. Use the [MCP Server setup guide](/dev-tools/mcp-server) instead.
If you're a Plane Cloud user connecting to `mcp.plane.so`, you don't need this. Use the
[MCP server setup guide](/dev-tools/mcp-server) instead.

## Prerequisites

- A running **Plane instance** (self-hosted or Cloud) with workspace admin access
- **Docker** and Docker Compose v2+, _or_ **Kubernetes** v1.21+ with Helm v3+
- A **public URL** for the MCP server (e.g. `https://mcp.yourdomain.com`) - OAuth callbacks must be able to reach it over HTTPS
- A **public URL** for the MCP server (e.g. `https://mcp.yourdomain.com`) — OAuth callbacks must reach it over HTTPS

## Register an OAuth app in Plane

The MCP server authenticates users through Plane's OAuth 2.0 system. You need to register an app to get a Client ID and Client Secret.

A previously registered `https://mcp.yourdomain.com/callback` URI is harmless but unnecessary.

Plane Helm chart plane-mcp-server extraEnv environment variables chart templates

💡 Result:

As of August 2026, there is no official, published Helm chart specifically for the plane-mcp-server [1]. While there have been community discussions and pull requests aimed at creating one, the primary documentation for the Plane MCP server focuses on direct configuration via environment variables (such as PLANE_API_KEY, PLANE_WORKSPACE_SLUG, and PLANE_BASE_URL) rather than Helm deployment [2][3][4]. For the main Plane platform Helm charts (plane-ce and plane-enterprise), the platform does provide a mechanism for injecting additional environment variables globally across its workloads using an extraEnv parameter [5]. If you are working with the main Plane Helm charts, you can define custom environment variables in your values.yaml file using the following structure [5]: extraEnv: - name: CUSTOM_VAR_NAME value: "your-value" - name: ANOTHER_VAR value: "another-value" This extraEnv setting applies the defined environment variables to all workloads (web, api, worker, etc.) within the deployment [5]. Important Considerations: 1. Plane MCP Server Deprecation: Note that the Node.js-based plane-mcp-server is deprecated [2][6][7]. The current recommendation is to use the Python-based implementation, which is typically configured as an MCP server for your AI client (e.g., in your Claude or other MCP-compatible editor configuration file) rather than as a standalone Kubernetes service [2][3]. 2. Helm Chart Availability: Because the dedicated plane-mcp-server Helm chart is not officially published, if you require a containerized deployment of the MCP server, you would currently need to create your own Kubernetes deployment manifests or custom Helm chart using the official Plane MCP container image [1]. 3. OAuth Configuration: There have been reports that specific configurations for MCP server OAuth integration are currently missing from the standard Community Edition Helm charts, which may complicate direct integration in some self-hosted environments [8].

Remove or correct the Helm deployment section.

https://helm.plane.so publishes only plane-ce and plane-enterprise. It has no plane-mcp-server chart, so the documented helm install command cannot work. Publish the MCP chart, or document the supported Kubernetes deployment method and its actual environment-variable configuration. Do not document extraEnv unless the chart templates support it.

The chart does exist — plane-mcp-server (v1.3.0) in Plane's commercial Helm repository — but it isn't published to helm.plane.so, so this section (which predates this PR) currently points at the wrong repo. Flagging to the team to either publish the chart to helm.plane.so or point this section at the commercial repository; the environment-variable wording here does not claim extraEnv support.

@vihar, thanks for the clarification.

The extraEnv concern does not apply. The current wording only states that unsupported Helm values must be set on the deployment.

The finding remains valid for the repository URL. The documented helm repo add plane https://helm.plane.so command cannot install plane-mcp-server until the chart is published there. The section should either use the commercial Helm repository or wait for publication to helm.plane.so.

Learning: The `plane-mcp-server` Helm chart exists as version `1.3.0` in Plane's commercial Helm repository. It is not currently published to `https://helm.plane.so`. In `docs/dev-tools/mcp-server-self-host.md`, the Helm deployment section predates pull request `#313` and currently points to `https://helm.plane.so`, so its `plane-mcp-server` install command cannot work until the chart is published there or the documentation uses the commercial repository.

## Logging and observability

The server emits structured JSON logs with the tool name, duration, status, opaque user ID, and workspace slug.

`LOG_USER_INFO` defaults to `false`. Setting it to `true` also logs the user's display name, which is personally
identifiable information.
