## Common questions

### What is the io.github.GuardBee/context-oversharing-auditor MCP server?

io.github.GuardBee/context-oversharing-auditor is an MCP server listed in the public MCP registry as io.github.GuardBee/context-oversharing-auditor. OWASP MCP10 context oversharing: session dumps, unscoped memory, shared context, prompt leaks. This page covers its npm package (@guardbee/mcp-context-oversharing-auditor).

### Is the io.github.GuardBee/context-oversharing-auditor MCP server safe to use?

io.github.GuardBee/context-oversharing-auditor scores 85 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 25 October 2026. It declares no install or post-install scripts. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the io.github.GuardBee/context-oversharing-auditor MCP server expose?

io.github.GuardBee/context-oversharing-auditor exposes 4 tools: scan_text, scan_file, scan_directory, list_patterns. Their descriptions and schemas cost roughly 249 tokens of context every time the server is loaded.

### Is the io.github.GuardBee/context-oversharing-auditor MCP server still maintained?

io.github.GuardBee/context-oversharing-auditor is still listed as active in the MCP registry. We last reached this channel on 25 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the io.github.GuardBee/context-oversharing-auditor MCP server under?

io.github.GuardBee/context-oversharing-auditor declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
