## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

## Common questions

### What is the Pixeltable Developer MCP server?

Pixeltable Developer is an MCP server listed in the public MCP registry as io.github.pixeltable/mcp-server-pixeltable-developer. Pixeltable MCP server for declarative multimodal tables, computed columns, and services. This page covers its PyPI package (mcp-server-pixeltable-developer).

### Is the Pixeltable Developer MCP server safe to use?

Pixeltable Developer scores 82 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. 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 Pixeltable Developer MCP server expose?

Pixeltable Developer exposes 18 tools: pixeltable_list_catalog, pixeltable_describe, pixeltable_rows, pixeltable_get_row, pixeltable_errors, and 13 more. Their descriptions and schemas cost roughly 1,224 tokens of context every time the server is loaded.

### Is the Pixeltable Developer MCP server still maintained?

Pixeltable Developer is still listed as active in the MCP registry. We last reached this channel on 5 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 Pixeltable Developer MCP server under?

Pixeltable Developer declares the Apache-2.0 licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.

### What did VerifyMCP test on the Pixeltable Developer MCP server?

VerifyMCP ran 16 checks on Pixeltable Developer, covering Malware scan, Known CVEs, Install scripts, Dependency health and 12 more. Endpoint Security and Transport & Reachability do not apply to a PyPI package, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
