Reviewer Notes

Sigma Computing has an OpenAPI but lacks an MCP server or llms.txt, making discoverability moderate. Account creation is OAuth/SAML only—no API key signup or programmatic registration, blocking autonomous agent signup. The API is functional with REST endpoints for workbooks, worksheets, and queries, but documentation is geared toward human developers rather than agent integration. The free tier and sandbox environment are positive, but enterprise-focused pricing and lack of agent-specific tooling limit autonomous operation. Reliability appears solid (established vendor), but the OAuth-only auth model and absence of agent discovery mechanisms are the main weaknesses.
