## 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)

Scored 2026-09-21.

- **Supply Chain Security**: 50/100

## Common questions

### What is the mcp-server-sigma server?

mcp-server-sigma is listed in the public MCP registry as io.github.christianclaudio/sigma. MCP server for Sigma Computing. Provision dashboards, build models, and automate cloud analytics. This page covers its PyPI package (mcp-server-sigma).

### Is the mcp-server-sigma server safe to use?

mcp-server-sigma scores 66 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 21 September 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 mcp-server-sigma server expose?

mcp-server-sigma exposes 155 tools: sigma_list_connections, sigma_get_connection, sigma_sync_connection, sigma_test_connection, sigma_list_columns_for_table, and 150 more. Their descriptions and schemas cost roughly 6,397 tokens of context every time the server is loaded.

### Is the mcp-server-sigma server still maintained?

mcp-server-sigma is still listed as active in the MCP registry. We last reached this channel on 21 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
