FeedMob Direct Spend Visualizer – n8n Nodes

These community nodes wrap the FeedMob Claude Agent plugin (“direct spend visualizer”) so that n8n workflows can trigger Claude via AWS Bedrock, run FeedMob’s MCP-aware skill, and emit chart-ready direct spend insights without writing custom code.

Requirements

1. npm install automatically clones feed-mob/claude-code-marketplace into vendor/claude-code-marketplace. Ensure git is on the host; rerun npm install (or node scripts/setup-plugin.js) anytime you need the latest plugin changes.
2. FeedMob MCP credentials (FEEDMOB_KEY, FEEDMOB_SECRET, FEEDMOB_API_BASE) are required. Generate keys at FeedMob Admin → API Keys.
3. Supply AWS Bedrock credentials with access to Anthropic Claude models (AWS_REGION, AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY). The node sets CLAUDE_CODE_USE_BEDROCK=1 and uses your configured model IDs.

Local development

Follow the official n8n guide: https://docs.n8n.io/integrations/creating-nodes/test/run-node-locally/

Steps

1. Install n8n globally

   npm install n8n -g

2. Build and link this node

   cd src/n8n-nodes-feedmob-direct-spend-visualizer
   npm install
   npm run build
   npm link

3. Link the node into your local n8n installation

   # Navigate to your n8n custom nodes directory
   # e.g., ~/.n8n/custom or ~/.n8n/<CUSTOM_NAME> if N8N_CUSTOM_EXTENSIONS is set
   cd ~/.n8n/custom
   npm link @feedmob/n8n-nodes-feedmob-direct-spend-visualizer

   Note: If ~/.n8n/custom doesn't exist, create it manually and run npm init -y before linking.

4. Start n8n

   n8n start

5. Test the node Open http://localhost:5678 and search for "Direct Spend Visualizer" in the node panel (search by node name, not package name).

Ensure AWS and FeedMob credentials are available in the n8n process environment for the Claude Agent SDK to authenticate properly.

Installing inside n8n

• n8n Cloud / UI – Settings → Community Nodes → Install → enter @feedmob/n8n-nodes-feedmob-direct-spend-visualizer.
• Self-hosted – include N8N_COMMUNITY_PACKAGES="@feedmob/n8n-nodes-feedmob-direct-spend-visualizer" in your process / container env variables.

Make sure community nodes are allowed for your workspace before installing.

Credentials

Create credentials of type FeedMob Direct Spend Visualizer and fill the following fields:

| Field | Description | | --- | --- | | AWS Region | Defaults to us-east-1. Region used for Bedrock Claude. | | AWS Access Key ID | Required. Must have permissions to invoke Anthropic models via Bedrock. | | AWS Secret Access Key | Required. Secret for the above key. | | FeedMob Key | Required. Exported to FEEDMOB_KEY for the plugin’s MCP server (create via https://admin.feedmob.com/api_keys). | | FeedMob Secret | Required. Exported to FEEDMOB_SECRET (create via https://admin.feedmob.com/api_keys). | | FeedMob API Base | Required. Exported to FEEDMOB_API_BASE. | | Anthropic Model (primary) | Defaults to us.anthropic.claude-sonnet-4-20250514-v1:0. | | Anthropic Model (fast) | Defaults to us.anthropic.claude-3-5-haiku-20241022-v1:0. |

Supported operations

| Operation | Description | | --- | --- | | Visualize Spend | Provide start_date, end_date, and click_url_id. The node loads vendor/claude-code-marketplace/plugins/direct-spend-visualizer, starts the Claude Agent SDK (with allowedTools: ["Skill","mcp__plugin_direct-spend-visualizer_feedmob__get_direct_spends"]), and returns the skill’s ASCII chart plus JSON (status, summary, data). |

Troubleshooting tips

• The plugin is bundled under vendor/claude-code-marketplace/plugins/direct-spend-visualizer. If it’s missing or out of date, rerun npm install or execute node scripts/setup-plugin.js.
• The Agent SDK call whitelists the FeedMob MCP tool (mcp__plugin_direct-spend-visualizer_feedmob__get_direct_spends) so it can access the API without prompting. Ensure your FeedMob credentials are valid or the tool will fail with a permission error.
• Max turns default to 50 to give Claude enough room to fetch data, render ASCII charts, and format the JSON output. Lower this in the node settings if you need faster runs.

Scripts

• npm run build – compile TypeScript and copy the SVG icon into dist/.
• npm run dev – run TypeScript in watch mode during development.
• node scripts/setup-plugin.js – reclone or refresh the FeedMob plugin marketplace (normally run for you during npm install).
