Print PDFs, ZPL labels and ESC/POS receipts on your printers and follow print jobs via InkRelay
MCP server, Agent Skill and Claude Code plugin for InkRelay, a cloud printing API. Use them to let an AI assistant print on your printers, or to have a coding agent add printing to your app.
| Piece | Use it to | Install |
|---|---|---|
@inkrelay/mcp | List printers, print PDFs, ZPL labels and ESC/POS receipts, follow jobs, manage webhooks from an MCP client | npx -y @inkrelay/mcp |
inkrelay-printing skill | Give a coding agent the API rules, SDK usage, webhook verification and raw printing details | Claude Code plugin, or copy the folder |
inkrelay-integrator agent | Add printing to a project: SDK, config, print module, webhook route, tests, one test print | Claude Code plugin |
| Docs MCP server | Search the InkRelay docs from an MCP client | https://docs.inkrelay.app/mcp |
| AGENTS.md snippet | Give agents without skills the same rules | Paste into AGENTS.md, CLAUDE.md or Cursor rules |
Sign in at app.inkrelay.app and create a key under API keys. A test key (ir_test_...) prints only to four virtual printers (A4 laser, Letter color, 80 mm receipt, 4x6 label) and costs nothing.
Add the MCP server to Claude Code (other clients are in mcp/README.md):
claude mcp add-json inkrelay '{"command":"npx","args":["-y","@inkrelay/mcp"],"env":{"INKRELAY_API_KEY":"ir_test_your_key"}}'
Ask: "Print https://inkrelay.app/sample.pdf on Test A4 Laser and tell me when it is done."
Installs the MCP server, the docs MCP server, the skill and the agent together. Set INKRELAY_API_KEY in your shell, start Claude Code and run:
/plugin marketplace add GauravBR/inkrelay-ai
/plugin install inkrelay@inkrelay
Then ask, for example: "Add label printing to this app with InkRelay."
Copy plugins/inkrelay/skills/inkrelay-printing into your agent's skills folder (for Claude Code, .claude/skills/ in the project or ~/.claude/skills/). It uses the Agent Skills format (SKILL.md with name and description), so other agents that read that format can load it too.
