Mcp MCP Server

@kaminari-ad/mcp

Official Model Context Protocol (MCP) server for Kaminari Ad — the ad verification platform from the team behind Kaminari Click.

Lets AI agents (Cursor, Claude Desktop, Cline, and any MCP-compatible client) launch scans, inspect results, manage campaigns and policies, and read alerts directly against your Kaminari Ad workspace via your API key.

Install (one click)

Cursor

What the server can do and how to connect any client: Kaminari Ad MCP overview.

Claude Desktop

Download kaminari-ad-mcp.mcpb → double-click to install. Claude Desktop shows a config form for your API key.

Claude Code (CLI)

claude mcp add kaminari-ad -- npx -y @kaminari-ad/mcp
export KAMINARI_AD_API_KEY=your-key

Full installation docs — see Quick start below.

Quick start

1. Sign up & get an API key

1. Sign up at https://app.kaminari.ad/signup (free tier, no card required).
2. Once signed in, go to Settings → API Keys and generate a new key, OR have an existing AI assistant (with a temporary login) call the create_api_key tool — both paths produce the same result.
3. The key is shown once. Copy it. The full key is hashed server-side immediately.

Keys are opaque random strings — no required prefix or fixed length. Treat the whole value as a raw secret and paste it verbatim into your client config.

Tip for evaluators / Anthropic Software Directory reviewers: ask the team at hello@kaminari.ad for a sandboxed test account with seeded sample scans, campaigns, and alerts.

2a. Local install (stdio transport)

Add to your MCP client config (Cursor: ~/.cursor/mcp.json; Claude Desktop: ~/Library/Application Support/Claude/claude_desktop_config.json):

{
  "mcpServers": {
    "kaminari-ad": {
      "command": "npx",
      "args": ["-y", "@kaminari-ad/mcp"],
      "env": {
        "KAMINARI_AD_API_KEY": "<your-kaminari-ad-api-key>",
      },
    },
  },
}

Restart your client. You should see kaminari-ad in the MCP servers list with 108 tools exposed.

2b. Hosted HTTP transport (no install)

For cloud agents or clients without a local Node runtime, point at the hosted endpoint:

{
  "mcpServers": {
    "kaminari-ad": {
      "url": "https://mcp.kaminari.ad/mcp",
      "headers": {
        "Authorization": "Bearer <your-kaminari-ad-api-key>",
      },
    },
  },
}

2c. OAuth 2.0 (Claude directory, third-party agents)

The hosted server publishes RFC 9728 protected-resource metadata at https://mcp.kaminari.ad/.well-known/oauth-protected-resource and points at the Kaminari Ad Authorization Server (https://app.kaminari.ad). Any unauthenticated request to /mcp returns a WWW-Authenticate: Bearer resource_metadata="…" header so spec-compliant MCP clients (Claude.ai, Claude Code, third-party agents) can complete an OAuth 2.0 authorization-code flow with PKCE S256 + Dynamic Client Registration (RFC 7591).

# Discovery — works without any credential
curl -sk https://mcp.kaminari.ad/.well-known/oauth-protected-resource

# Triggering the WWW-Authenticate hint
curl -isk https://mcp.kaminari.ad/mcp -X POST \
  -H 'content-type: application/json' \
  -d '{"jsonrpc":"2.0","method":"tools/list","id":1}'

API keys remain the recommended path for CLIs and one-off scripting — OAuth is only for interactive agents that want per-app consent and per-app revocation. Both Bearer flavours hit the same /mcp endpoint; the server forwards the token verbatim to the API, which decides which credential type minted it.

Tools

109 tools covering the public /api/v1 surface of Kaminari Ad. Every tool carries MCP behaviour annotations (title, readOnlyHint, destructiveHint, idempotentHint, openWorldHint) so MCP clients can warn before destructive actions. The complete list, by domain:

• Account (14) — get_account, update_org, list_org_users, invite_user, update_user_role, remove_user, transfer_ownership, list_org_roles, create_custom_role, list_account_labels, update_account_labels, list_api_keys, create_api_key, revoke_api_key
• Scans (13) — list_scans, get_scan, list_scan_children, create_scan, create_bulk_scans, recheck_scans, cancel_scan, get_scan_screenshot, get_scan_creative_screenshot, get_scan_landing_screenshot, get_scan_creative_html, get_scan_creative_video, get_scan_vast_xml
• Campaigns (10) — list_campaigns, list_campaigns_picker, get_campaign, create_campaign, update_campaign, archive_campaign, unarchive_campaign, cancel_campaign, run_campaign, list_campaign_runs
• Campaign groups (10) — list/get/create/update/run/cancel/archive/unarchive + pause_campaign_group_schedule, resume_campaign_group_schedule
• Runs (3) — get_run, list_run_scans, cancel_run (use list_campaign_runs to enumerate runs of a campaign — the API has no standalone /runs index)
• Tags (5) — list_tags, get_tag_definition, update_tag_definition, delete_tag_definition, list_scan_tags
• Custom rules (7) — list_custom_rules, get_custom_rule, create_custom_rule, update_custom_rule, delete_custom_rule, test_custom_rule, test_custom_rules_batch
• Custom taxonomies (7) — list_custom_taxonomies, get_custom_taxonomy, create_custom_taxonomy, update_custom_taxonomy, delete_custom_taxonomy, restore_custom_taxonomy, parse_custom_taxonomy_text
• Policy sets (11) — list_policy_sets, get_policy_set, create_policy_set, update_policy_set, delete_policy_set, request_policy_set_approval, unpublish_policy_set, set_default_policy_set, list_policy_set_campaigns, attach_policy_set_campaigns, detach_policy_set_campaigns
• Alerts (4) — list_alerts, update_alert_status, bulk_update_alert_status, get_alert_stats
• Webhooks (11) — list_webhooks, get_webhook, create_webhook, update_webhook, delete_webhook, list_webhook_event_types, list_webhook_deliveries, test_webhook, rotate_webhook_secret, replay_webhook_delivery, bulk_replay_webhook
• Billing (4) — get_billing_summary, list_usage, get_usage_summary, list_balance_history
• Invoicing (2) — list_invoices, get_invoice_pdf
• Alert notifications (5) — list_alert_destinations, delete_alert_destination, set_alert_destination_version, get_campaign_alert_overrides, set_campaign_alert_overrides
• Reference data (3) — list_geos, list_emulators, get_proxy_targeting

Screenshots (get_scan_screenshot, get_scan_creative_screenshot, get_scan_landing_screenshot) come back as inline MCP image blocks; get_invoice_pdf and get_scan_creative_video as inline resource blocks — no second fetch, no presigned URL. The two text artifacts (get_scan_creative_html, get_scan_vast_xml) come back as strings the model can read directly. Every artifact download is size-capped in the gateway — 256 KiB for the text artifacts, 8 MiB for the binary ones — and refused while reading rather than buffered and then rejected.

Not exposed (intentionally): the public marketing forms, which are anonymous intake for kaminari.ad itself rather than an agent capability.

Example agent prompts

These three prompts each exercise a different cross-section of tools and demonstrate the typical agent workflow:

1. "Scan https://news.example.com/article-promo across US, UK, DE on mobile profiles, flag anything that redirects to a paywall." Touches list_emulators → create_bulk_scans → wait → list_scans (status=completed) → get_scan → list_scan_tags.
2. "Create a campaign that re-checks the homepage of brand-x.com every hour from JP and US; alert me on Slack if it ever shows a malware tag." Touches list_emulators → list_policy_sets (find one with malware) → create_campaign (schedule_enabled=true) → attach_policy_set_campaigns → list_alert_destinations → set_campaign_alert_overrides (mode: "override" with the Slack destination).
3. "What did I spend on ad verification last month, and which campaigns drove the cost?" Touches get_usage_summary → list_usage (with date_from/date_to) → group by scan_id → get_scan → get_campaign for attribution.

Full machine-readable tool listing is exposed by the server itself — connect with any MCP client and call tools/list.

Security & tenant isolation

The hosted HTTP endpoint serves many organizations from a single process. We take cross-tenant isolation very seriously:

• The MCP server is a strict, stateless, per-request pass-through. It forwards your Authorization header to the Kaminari Ad API verbatim and stores no per-tenant state between requests.
• No caches, no in-memory data indexed by anything tenant-related.
• KAMINARI_AD_API_KEY env var is rejected on startup in HTTP mode (stdio only) — no default fallback token exists.
• Session IDs are bound to the SHA-256 of the Bearer that initialized them; reuse with a different Bearer is rejected.
• Bearers are never logged. Only their 8-character hash prefix is recorded for correlation.
• See tests/isolation/ for the regression suite that enforces every rule above on each CI run.

To report a security issue, see SECURITY.md.

Development

The Docker path (no local Node required for the build, but see CONTRIBUTING for the host-side commit hooks):

make check           # lint + format-check + typecheck + arch-gates + test-cov
make test            # full test suite
make test-unit       # unit only
make test-isolation  # tenant-isolation suite

Or directly with npm if you have Node >=22.19.0 on the host (matches engines.node; .nvmrc pins the minor for dev parity with CI). The package gates strictly at 22.19.0 because undici@8.x requires markAsUncloneable from node:worker_threads (Node 22.19+).

npm ci --legacy-peer-deps
npm run lint && npm run typecheck && npm test

See CONTRIBUTING.md for the development workflow and how to add a tool.

The maintainers run the full development gate (integration tests, deploy automation, prod smoke) on a private GitLab instance and mirror the repo to GitHub. The public CI on GitHub Actions (.github/workflows/ci.yml) runs lint + typecheck + unit tests + build + bundle-size check on every community PR, so contributors get fast green/red feedback without needing access to the internal infra. Tag pushes (v*.*.*) trigger .github/workflows/release.yml, which publishes the package to npm with OIDC provenance, creates the GitHub Release and publishes server.json to the official MCP Registry.

Stability

The public surface of this package is:

1. The CLI binary kaminari-ad-mcp and its --transport stdio|http flag, the env vars documented in .env.example, and the exit codes (0 / 1 fatal / 2 invalid config).
2. The MCP wire protocol as implemented by every registered tool (tool names, input schemas, output shapes, annotations). Tools deprecated in a future major version will keep working for at least one minor version with a console warning.

Everything else — the TypeScript types exported from dist/bin.d.ts, deep imports, internal class shapes — is not part of the public contract and may change in any release. Treat this package as a CLI, not a library.

We follow Semantic Versioning for the two items above. See CHANGELOG.md for the per-release record.

Privacy

• Data collected by the MCP server itself: none beyond the Authorization header it forwards. The HTTP transport is stateless — no sessions are persisted; each request is authenticated independently by its own Bearer. The only in-memory state is the leaky-bucket rate limiter keyed by sha256(bearer).
• Data forwarded to Kaminari Ad: every tool call is a thin pass-through to /api/v1 over HTTPS. The Kaminari Ad privacy policy applies: https://kaminari.ad/privacy.
• Logs: structured pino output, JSON in HTTP mode. The full Bearer token is redacted; only bearer_hash = sha256(token).slice(0,8) makes it into a log line, alongside request_id, tool_name, api_status, elapsed_ms. Tool inputs (which may contain customer scan IDs / URLs) are NOT logged.
• Telemetry: none. The OSS build ships a NoopErrorReporter. We do not bundle Sentry, OpenTelemetry exporters, or PostHog.

To report a security or privacy issue, see SECURITY.md.
