Security scanner for AI agent tool definitions


01Tools · 5

How to read this: tool names here are observed from a live tools/list handshake. The Risk label is a heuristic inferred from the tool name (write/destructive verbs), not from executing the tool — a conservative guess, not a verified capability. We never escalate risk from a description. Found one that's wrong? Tell us — we fix on report.

ToolRiskSide effectsApproval
tooltrust_list_rules
Returns the full catalog of security rules used by the ToolTrust scanner, including rule IDs, titles, and descriptions. Useful for understanding what the scanner checks for.
readfalseunknown
tooltrust_scanner_scan
Scan a list of AI agent tool definitions for security risks. Accepts an MCP tools/list JSON payload and returns a risk report with gateway policies (ALLOW, REQUIRE_APPROVAL, or BLOCK) for each tool.
readfalseunknown
tooltrust_lookup
Look up historical security risk grades for an MCP server from the public ToolTrust Directory. Accepts the kebab-case name of the server and returns its full JSON scan report, or 404 if not found.
readfalseunknown
tooltrust_scan_config
Reads the user's Claude Code MCP configuration and scans all configured servers in parallel. Searches for .mcp.json in the current directory, then ~/.claude.json as fallback. Returns a summary report with scan results for each server. Servers that fail to start are reported with an error note; scanning continues for remaining servers.
readfalseunknown
tooltrust_scan_server
Connects to a live MCP server via standard input/output (stdio), parses its tools, and scans them for prompt injection, data exfiltration, and privilege escalation risks. Returns a risk report with gateway policies (ALLOW, REQUIRE_APPROVAL, or BLOCK) for each tool.
