Summary

Adding SIGIL (sigil-eu/sigil-py) to the Community Servers list.

SIGIL is a Python security middleware for AI agent tool calls that provides:

  • Secret scanning: 43+ patterns (AWS, OpenAI, GitHub tokens, PII, prompt injection)
  • Policy enforcement: allow/block tool call arguments at runtime
  • Tamper-evident audit logging: cryptographically chained log entries
  • Works with MCP, LangChain, CrewAI, AutoGen, and OpenAI Agents SDK

MIT licensed — installable via pip install sigil-protocol.

Placement

Inserted alphabetically in the Community Servers list, between Shopify Storefront and Simple Loki MCP.
