Skylos vs Sentry MCP
Two MCP servers from our developer tools ranking, compared on live data - updated nightly, never sponsored.
Bottom line · 2026-08-25
Sentry MCP records significantly more monthly package installs (460,591 vs 133,796); both are actively maintained, with commits inside the last month.
How they differ in kind
Skylos focuses on: Open-source, local-first checks for dead code, security issues, secrets, quality regressions, and AI-code mistakes before merge. Sentry MCP focuses on: Sentry's MCP service is primarily designed for human-in-the-loop coding agents. Environment-variable extraction: Skylos yielded no variables extracted; Sentry MCP yielded 5 variables. Implementation languages differ (Python vs TypeScript).
What each one does
Skylos
Open-source, local-first checks for dead code, security issues, secrets, quality regressions, and AI-code mistakes before merge.
From the project's README.
Sentry MCP
Sentry's MCP service is primarily designed for human-in-the-loop coding agents. Our tool selection and priorities are focused on developer workflows and debugging use cases, rather than providing a general-purpose MCP server for all Sentry functionality. It runs locally over stdio via the published package.

Which one, for what
Derived from the signals above, not hands-on testing.
Pick Skylos if…
- → release velocity matters - 10+ releases in 90 days vs 2
- → clear licensing matters - Apache-2.0 vs undeclared
Pick Sentry MCP if…
- → you want the more widely installed option - 460,591 monthly installs vs 133,796
- → you prefer a TypeScript codebase to extend or audit

Quick answers
Is Skylos better than Sentry MCP?
Package installs favor Sentry MCP: 460,591 monthly installs to 133,796. Skylos still ranks #4 of 139 maintained developer tools servers. Data as of 2026-08-25; we haven't hands-on tested either.
Can I use Skylos and Sentry MCP together?
Yes - MCP clients accept multiple servers in one config, so you can enable both developer tools servers side by side. If their tools overlap, keep the one whose toolset fits to keep your agent's tool list lean.
What environment variables do their READMEs document?
Skylos: no environment variables extracted from the README setup; Sentry MCP: 5 environment variables extracted from the README setup. Extraction does not rule out other authentication or configuration steps; check each project's current documentation.
