Campaign Manager 360 MCP Server

Cesteral MCP Servers

Self-hostable MCP connectors for major advertising platforms.

Use this repo when you want transparent platform integrations, local experimentation, and infrastructure you control. Use Cesteral Intelligence when your team needs approvals before spend commits, credential brokering, auditability, and cross-platform execution from one governed environment.

Two Ways to Use This

This repo is an open connector layer, not the full product.

• Self-host a connector for transparency and direct control of your credentials, infrastructure, and platform access.
• Use Cesteral Intelligence when the workflow needs governed writes, team approvals, credential brokering, auditability, and cross-platform coordination — see when you need it below.

When You Need Cesteral Intelligence

The OSS connectors give you per-server tool execution + audit logs. Cesteral Intelligence layers governance and orchestration on top:

• Credential brokering -- keep platform secrets out of local operator workflows
• Approval workflows -- require human review before destructive or high-spend changes
• Aggregated audit -- unified, cross-server activity feed with provenance, tied to operator identity
• Cross-platform orchestration -- coordinate governed execution across multiple connectors
• Team operations -- shared workflows, tenant isolation, and operator visibility

dv360-mcp	DV360 API v4	26	Google OAuth2 / service account
ttd-mcp	The Trade Desk REST + GraphQL API	43	User token (TTD-Auth header)
linkedin-mcp	LinkedIn Marketing API v2	21	Bearer token

Thirteen servers, 290+ tools. Tool counts are the live registered total per server, including the *_search_tools discovery tool where present.

What Every Server Ships

These connectors have grown past "thin REST wrappers." Beyond raw tool calls, every server in the fleet exposes the full surface of the modern MCP spec (protocol revisions 2025-03-26 through 2025-11-25):

• MCP Prompts — on-demand, multi-step workflow guidance (campaign launch, reporting, troubleshooting) so agents don't have to rediscover each platform's sequencing. Present on all 13 servers.
• MCP Resources — structured, addressable context (schemas, field catalogs, examples, enums) fetched on demand instead of bloating every tool schema. Present on all 13 servers. DV360 uses these to keep its >1 MB discriminated unions off the wire (entity-schema://, entity-fields://, entity-examples://).
• Tool discovery — a <platform>_search_tools tool that lets an agent search the server's own catalog by intent instead of paging the full list. On 11 servers (all except the small gads-mcp and sa360-mcp / reporting-only dbm-mcp).
• Server discovery cards — SEP-2127 metadata at /.well-known/mcp/server-card.json (name, version, transports, auth modes, capabilities) on every server, in every auth mode.
• OAuth resource discovery — in jwt auth mode, the RFC 9728 endpoint at /.well-known/oauth-protected-resource.
• Report CSV spill — large report bodies spill to GCS behind a signed URL so responses stay bounded. On the six reporting-heavy servers: ttd-mcp, tiktok-mcp, snapchat-mcp, amazon-dsp-mcp, pinterest-mcp, msads-mcp.

Built for Production

Self-hosting an AI agent that touches live ad spend is a trust problem first and a capability problem second. Two things make this fleet shippable to production without hand-rolling guardrails:

• Audit-grade observability. Every tool call is captured as append-only JSONL. Failures additionally capture the full upstream HTTP trail — every request, every retry, every response — with secrets redacted at the source. Query it directly in BigQuery for hosted deployments, or pipe stdout to your existing log stack for self-host. Read the observability guide.
• Destructive-action elicitation gates. 51 destructive tools across the twelve write-capable servers (dbm-mcp is reporting-only) prompt the user before deletes, bulk status changes, bid adjustments, budget changes, conversion uploads, and async Workflows batch jobs. Stdio and clients without elicitation support fall back to a documented non-interactive contract. Bulk mutations under 10 items skip the prompt unless they touch a sensitive field (status / budget / bid).
• Verifiable release provenance. Governed tools carry a canonical SHA-256 definitionHash (from @cesteral/contract-hash) emitted into a per-package cesteral-manifest.json. Tagged releases publish to npm with build provenance, signing the manifest transitively inside the tarball, so a downstream governance system can verify exactly which tool definitions shipped and promote matching tools to attested trust.

If your security review needs evidence — the redaction list, the field schema, the upstream capture path, the contract hash — all of it is in this repository.

Quick Start

For a guided walkthrough, see the 10-minute quickstart.

Prerequisites

• Node.js >= 20.0.0
• pnpm >= 10.0.0 -- corepack enable picks up the pinned version from packageManager (or npm install -g pnpm@10)
• Docker (for containerization)
• Terraform >= 1.6.0 (for deployment)

1. Clone and install

git clone https://github.com/cesteral/mcp-open-advertising.git
cd mcp-open-advertising
pnpm install

2. Build

pnpm run build

3. Run a server locally

# Start any server using the dev script
./scripts/dev-server.sh gads-mcp    # port 3004
./scripts/dev-server.sh meta-mcp    # port 3005
./scripts/dev-server.sh dv360-mcp   # port 3002

# See each package README for required environment variables

4. Configure your AI agent

{
  "mcpServers": {
    "cesteral-gads": {
      "url": "https://gads.your-domain.com/mcp",
      "apiKey": "your-gads-api-key"
    },
    "cesteral-meta": {
      "url": "https://meta.your-domain.com/mcp",
      "apiKey": "your-meta-api-key"
    }
  }
}

Add as many servers as you need. Each runs independently and can be deployed separately.

5. Deploy

cd terraform
terraform init
terraform apply -var-file=dev.tfvars

See the deployment guide for production setup.

Architecture

Cesteral uses a GCP-native architecture with thirteen independently deployable Cloud Run MCP services. Each server exposes the MCP protocol directly via HTTPS on Cloud Run.

Key design decisions:

• Single cloud provider (GCP): Cloud Run, BigQuery, Pub/Sub, Secret Manager -- unified monitoring, ~$150-220/month
• Direct HTTP transport: No edge gateway layer needed
• Independent deployment: Each server can be deployed and scaled separately
• Composable: Use one server or all thirteen -- they work independently or together

AI clients connect directly to one or more MCP servers over HTTPS; there is no shared gateway to provision. Cesteral Intelligence, when used, layers tenancy, credentials, approvals, and governance above the same fleet.
