Sentry MCP

the best-engineered server on this list, and almost nobody knows

free with a sentry account#error-triage#debugging-without-leavin

skill-based tool narrowing, deliberate token-type separation, self-hosted support — it punches far above its 788 stars.

sentry's server handles issue, error, trace and performance inspection plus ai-powered search, and it is the most thoughtfully designed thing we reviewed. you can narrow the tool surface with `?skills=inspect,triage` or `?disable-skills=seer`, which directly addresses the context-bloat problem most servers ignore.

the auth design is unusually careful: it uses a distinct `Sentry-Bearer` header for pass-through sentry tokens, reserving plain `Bearer` for mcp oauth tokens, and documents that the worker does not store, validate, exchange or refresh the upstream token. that is the kind of detail that only shows up when someone has thought about failure modes.

the description above is ours, condensed from the ranking. pricing moves — check it on the vendor's own page before you rely on it.

our verdict

skill-based tool narrowing, deliberate token-type separation, self-hosted support — it punches far above its 788 stars.

we researched this category against vendors' own pricing pages and licence files. that is where this line comes from — not from the vendor, and not from anything they paid for.
