- `expireAfter` (integer)
- `filePath` (string): A file inside the folder this server runs in (or INKRELAY_FILE_ROOT)

### `cancel_print_job` (~44 tokens)

Cancel a print job

Cancels a job that is still queued or sent. Once the agent has received it, the API answers 409 not_cancellable.

Input parameters:

Prints the stored file of an earlier job again (files are kept 7 days), on the same printer or another one of the same mode.

Input parameters:

- `jobId` (string, required)

## Common questions

### What is the InkRelay MCP server?

InkRelay is an MCP server listed in the public MCP registry as io.github.GauravBR/inkrelay. Print PDFs, ZPL labels and ESC/POS receipts on your printers and follow print jobs via InkRelay. This page covers its npm package (@inkrelay/mcp).

### Is the InkRelay MCP server safe to use?

InkRelay scores 84 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 4 November 2026. It declares no install or post-install scripts. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the InkRelay MCP server expose?

InkRelay exposes 17 tools: whoami, list_computers, list_printers, get_printer, update_printer, and 12 more. Their descriptions and schemas cost roughly 1,369 tokens of context every time the server is loaded.

### Is the InkRelay MCP server still maintained?

InkRelay is still listed as active in the MCP registry. We last reached this channel on 4 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the InkRelay MCP server under?

InkRelay declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
