Field-by-field comparison

Compare the evidence before choosing an MCP.

Each signal stays separate, missing facts remain visible, and the column order follows your selection.

Uncheck an MCP to remove it. Comparing two or three keeps each signal in its own row.

Task fit
Best for
  • Developers debugging MCP servers, transports, tools, resources, and prompts
  • Testing a server before connecting it to a production AI client
  • Human-in-the-loop issue, event, trace, and performance investigation
  • Coding agents working on one constrained Sentry project
  • Teams using the supported hosted OAuth service
Not ideal for
  • Production automation that should run unattended
  • Inspecting untrusted servers with production credentials
  • General-purpose Sentry administration
  • Unattended remediation against production
  • Self-hosted users unwilling to configure tokens and optional LLM providers
Avoid when
  • You cannot isolate the target server or its credentials
  • Invoking target tools could create unacceptable side effects
  • Error payloads may contain secrets or personal data that cannot be shown to the model/client
  • You cannot constrain the session to the intended organization/project
  • The requested OAuth scopes or write-capable skills exceed policy

Access and data
AuthenticationInspector itself is a local developer tool; target-server authentication depends on the server and connection configuration.The hosted service uses MCP OAuth layered over Sentry OAuth; raw Sentry credentials stay server-side. Stdio uses a Sentry user auth token and may also require OpenAI or Anthropic credentials for AI-powered search.
CostOpen-source tool; any target APIs or services may have separate costs.The repository is source-available under its published license and the hosted MCP has no separately documented fee in the reviewed sources. Normal Sentry plan/usage, Seer, and external LLM-provider charges may apply.
PermissionsIt can list and invoke capabilities exposed by the target MCP server, so effective privileges are those of the connected server credentials.Hosted OAuth requests org:read, project:write, team:write, and event:write upstream, then narrows exposed actions through granted MCP skills and optional /mcp/:org/:project resource paths. Stdio documentation lists org/project/team read/write and event write token scopes.
Data handlingInputs and outputs from the target MCP server are visible in the inspection workflow; sensitive target data may therefore appear in the UI/session.Issue, event, trace, release, team, project, and related telemetry may be returned to the MCP client. Hosted mode stores upstream OAuth credentials in encrypted grant properties and gives the client a separate MCP token. AI search tools may process query/event context through configured model infrastructure.
Limitations
Tradeoffs
  • Inspector can reveal and invoke real server capabilities, so usefulness comes with the same side-effect risk as the target server
  • It is a development/debugging tool, not an isolation sandbox
  • The hosted server keeps upstream Sentry credentials server-side and narrows sessions by skills and paths, but requests broad upstream scopes.
  • AI-powered natural-language search may invoke an embedded model/provider; stdio self-hosting requires separate provider keys for those tools.
  • Self-hosted Sentry may lack features such as Seer and needs explicit skill disabling.
Risk contextHigh operational caution. Use test accounts or isolated environments when inspecting unknown or write-capable servers; do not assume rollback or sandboxing.Production error telemetry often contains sensitive values, while upstream OAuth scopes include write capabilities. Prefer a project-constrained hosted URL, minimal granted skills, human approval for mutations, and prior telemetry scrubbing.
