FAULTLINE

FAULTLINE builds open-source tools for AI agent reliability: measure repeated runs, check recorded traces before a release, and monitor MCP tool calls at runtime. Explore the platform.

Installable tools

Product Use it for Install Details
faultgate Check recorded AI agent traces for failure modes and business-rule violations; compare candidate runs with measured baseline variation and return PASS, FAIL, or INCONCLUSIVE in CI. pip install faultgate Source · PyPI · Docs
MCP Guard Monitor local stdio MCP servers for changed tool definitions and tool-description poisoning; audit calls by default and block supported rule violations in enforce mode. pip install mcp-integrity Source · PyPI

Naming: FAULTLINE MCP Guard is the product. Its Python package and command are named mcp-integrity; install it with pip install mcp-integrity.

Research
