Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

n8n Workflow Manager
Manage n8n workflows directly via the REST API. The MCP server only supports read/execute/publish — this skill fills the gap with full CRUD via curl.
Prerequisites
- n8n API key stored as
N8N_API_KEYin.claude/settings.jsonenv - n8n instance at https://
API Reference
Base URL: https:///api/v1 Auth: X-N8N-API-KEY: $N8N_API_KEY
List Workflows
curl -s -H "X-N8N-API-KEY: $N8N_API_KEY" "$BASE/workflows"Get Workflow

| Workflow | ID | Status | |---|---|---| | Acrid Single Post Pipeline | EVt8VtXvrtUUjTr4 | ACTIVE | | Acrid Content Pipeline | nT8vRFk1UcRiogU2 | INACTIVE | | Acrid Image Generator v2 | G8CRNb8XB3z7Xet6 | INACTIVE | | My workflow | YptFQoMBqSRQW9W9 | ACTIVE (test) |
Pending Task: Wire Image Generator into Single Post Pipeline
The Image Generator (G8CRNb8XB3z7Xet6) needs to be called by the Single Post Pipeline (EVt8VtXvrtUUjTr4) before posting to Buffer. The modification:
- GET the Single Post Pipeline workflow JSON
- Add an IF node after "Extract Post Data" that checks if
imageUrlis empty - On the TRUE branch: add Execute Sub-Workflow node calling Image Generator with pageId
- After sub-workflow: add HTTP Request to re-read Notion page for new image URL
- Add Code node to extract the image URL
- Connect both branches (has image / generated image) to the Buffer posting node
- PUT the modified workflow back
This requires network access to the n8n API. Execute in a session without sandbox restrictions.
