Side-by-side MCP evidence comparison
Evidence field	badchars-darknet-mcp-serverShortlist candidate	Sentry MCPMCP100 Recommended
Task fit
Best for	Supervised research that uses the publisher-documented dark-web search and retrieval tools in an isolated environment	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	General web search, unattended collection, or investigations that require guaranteed provenance and comprehensive coverage	General-purpose Sentry administration Unattended remediation against production Self-hosted users unwilling to configure tokens and optional LLM providers
Avoid when	The work lacks explicit authorization, a legal and safety review, an isolated environment, or a plan for handling harmful and sensitive material	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
Authentication	Provider API keys are optional environment variables for selected tools. MCP client authentication is not documented.	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.
Cost	The server has no documented project price. The README lists HIBP account and paste search as requiring a paid API key at $3.50 per month; other provider costs and limits vary.	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.
Permissions	Performs OSINT and threat-intelligence lookups, clearnet and onion fetch, scrape, and search, breach and stealer-log queries, malware intelligence, and blockchain, domain, and IP checks.	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 handling	Queries and indicators can be sent to external providers; outputs can include breach, stealer-log, and dark-web data. The README documents Tor SOCKS5H routing, local TTL caching, and HIBP password k-anonymity with only a five-character SHA-1 prefix sent.	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	A single MCP interface may speed specialized research, while upstream content can be unsafe, misleading, illegal to access, or operationally sensitive.	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 context	Sensitive breach, credential, malware, and dark-web intelligence crosses external providers and Tor infrastructure. Minimize submitted identifiers, protect provider keys, and handle retrieved sensitive data under an explicit retention policy.	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.
