# MCP Access Management
|
|
|
|
Infrastructure as Code for managing access to MCP community resources using Pulumi.
|
|
|
|
- Define groups in [`src/config/groups.ts`](src/config/groups.ts)
|
|
- Add users to groups in [`src/config/users.ts`](src/config/users.ts)
|
|
- Changes are applied via GitHub Actions when merged to the main branch
|
|
|
|
## What This Manages
|
|
|
|
- **GitHub Teams**: Automatically syncs team memberships in the MCP GitHub organization
|
|
- **Google Workspace Groups**: Automatically syncs group memberships for @modelcontextprotocol.io email accounts
|
|
- **Email Groups**: Groups with `isEmailGroup: true` accept emails from anyone (including external users) and notify all members. External posts are moderated for security.
|
|
|
|
## Deployment
|
|
|
|
### Production Deployment (Automated)
|
|
|
|
**Note:** Production deployment is automatically handled by GitHub Actions. All merges to the `main` branch trigger an automatic deployment via [the configured GitHub Actions workflow](.github/workflows/deploy.yml).
|
|
|
|
### Manual Deployment
|
|
|
|
Pre-requisites:
|
|
- [Pulumi CLI installed](https://www.pulumi.com/docs/iac/download-install/)
|
|
- [Google Cloud SDK installed](https://cloud.google.com/sdk/docs/install)
|
|
- Access to GCP project and GCS bucket
|
|
- Required credentials and secrets
|
|
|
|
1. Authenticate with GCP: `gcloud auth application-default login`
|
|
2. Get the passphrase file `passphrase.prod.txt` from the maintainers
|
|
3. Preview changes: `make preview`
|
|
4. Deploy changes: `make up`
|
|
|
|
## Key Management
|
|
|
|
### Required GitHub Secrets (for CI/CD)
|
|
|
|
The following secrets must be configured in GitHub Actions for automated deployments:
|
|
|
|
- **`GCP_PROD_SERVICE_ACCOUNT_KEY`**: GCP service account key
|
|
- Used to authenticate with Google Cloud Storage for Pulumi state (`gs://mcp-access-prod-pulumi-state`)
|
|
- Should be a JSON key file for a service account with Storage Admin permissions
|
|
- See "Setting Up GCS Backend" below for setup instructions
|
|
|
|
- **`PULUMI_PROD_PASSPHRASE`**: Passphrase for encrypting Pulumi state
|
|
- Used to decrypt encrypted values in Pulumi stack configuration
|
|
- Keep this secure - if lost, you cannot decrypt your Pulumi state
|
|
|
|
## Initial Setup
|
|
|
|
If setting up this infrastructure for the first time:
|
|
|
|
### 1. Set Up Service Account
|
|
|
|
```bash
|
|
# Create project and enable APIs
|
|
gcloud projects create mcp-access-prod
|
|
gcloud config set project mcp-access-prod
|
|
gcloud services enable storage.googleapis.com
|
|
gcloud services enable admin.googleapis.com
|
|
gcloud services enable groupssettings.googleapis.com
|
|
|
|
# Create service account
|
|
gcloud iam service-accounts create pulumi-svc \
|
|
--display-name="MCP Access Management Service Account" \
|
|
--description="Service account for Pulumi state and Google Workspace management"
|
|
|
|
# Grant storage admin permissions (for Pulumi state)
|
|
gcloud projects add-iam-policy-binding mcp-access-prod \
|
|
--member="serviceAccount:pulumi-svc@mcp-access-prod.iam.gserviceaccount.com" \
|
|
--role="roles/storage.admin"
|
|
|
|
# Create key
|
|
gcloud iam service-accounts keys create sa-key.json \
|
|
--iam-account=pulumi-svc@mcp-access-prod.iam.gserviceaccount.com
|
|
|
|
# Create GCS bucket for Pulumi state
|
|
gsutil mb gs://mcp-access-prod-pulumi-state
|
|
```
|
|
|
|
Then:
|
|
1. In Google Workspace Admin Console, go to **Account** → **Admin roles**
|
|
2. Select **Groups Admin** role (or create a custom role with these privileges):
|
|
- Read, create, update, and delete groups
|
|
- Read and update group members
|
|
3. Click **Assign service accounts**
|
|
4. Add your service account email: `pulumi-svc@mcp-access-prod.iam.gserviceaccount.com`
|
|
|
|
### 2. Initialize Pulumi Stack
|
|
|
|
```bash
|
|
# Login to Pulumi backend (GCS)
|
|
pulumi login gs://mcp-access-prod-pulumi-state
|
|
|
|
# Create production stack
|
|
export PULUMI_CONFIG_PASSPHRASE_FILE=passphrase.prod.txt
|
|
pulumi stack init prod
|
|
|
|
# Configure application secrets in Pulumi
|
|
pulumi config set --secret googleworkspace:credentials "$(cat sa-key.json)"
|
|
pulumi config set --secret github:token "ghp_your_github_token_here"
|
|
```
|
|
|
|
### 3. Configure GitHub Actions Secrets
|
|
|
|
Add the CI/CD secrets to GitHub Actions (repository settings → Secrets and variables → Actions):
|
|
- `GCP_PROD_SERVICE_ACCOUNT_KEY`: Content of `sa-key.json`
|
|
- `PULUMI_PROD_PASSPHRASE`: The passphrase you set above
