Questions
What is the Claude MCP server?
MCP Server implementation for Claude
What tools does Claude expose?
2 in total: 1 read-only, 1 that write, and 0 that can delete or overwrite. Every one is listed on this page with its risk.
Is Claude safe to connect to an agent?
The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B.
What credentials does Claude need?
No credential environment variables were found in its source, so it appears to need none.
How does Claude run?
It speaks stdio, so it runs as a local process your client starts.
How current is this page?
The grade is for one exact copy of the source (1be6f5a09501), read on 2026-10-08. The repository is watched and re-audited when it changes.
