Vigil — Cognitive Infrastructure for AI Agents MCP Server

Q: What runtime dependencies does Vigil require?

Vigil has zero dependencies beyond the Python standard library; MCP is optional and only needed for MCP transport.

Q: Which transports and auth does Vigil support?

Vigil supports stdio and SSE transports. The README does not mention authentication; it is not described.

Q: Where does Vigil store data?

Vigil uses SQLite for storage and requires zero external infrastructure.

Q: How is Vigil different from memory stores?

Vigil is not a memory store; it coordinates awareness across agents and sessions, unlike tools that simply store and retrieve data.

Q: What integrations are available?

Vigil integrates with Claude Code, Cursor, Claude Desktop, GitHub Actions, Slack, and Discord.

概览

What is Vigil?

Vigil is a cognitive infrastructure for AI agents that coordinates awareness across agents and sessions. It is not a memory store but a nervous system that helps agents boot with full context, filter tools to save tokens, and communicate via signals. It is built for developers using agent frameworks like Claude Code, Cursor, and Claude Desktop.

How to use Vigil?

Install via pip install vigil-agent, then run vigil quickstart to set up configuration and vigil serve --transport stdio to start the MCP server. Vigil exposes 12 MCP tools over stdio or SSE, and integrates with clients such as Claude Code, Cursor, and Claude Desktop.

Key features of Vigil

Awareness Daemon compiles system state every 90 seconds into hot context
Frame-based tool filtering saves 75–85% of tokens
Signal Protocol enables agent coordination via lightweight event bus
Session Handoff preserves context with structured summaries
Knowledge Auto-Extract identifies recurring patterns from signals
Event Triggers fire webhooks, Slack alerts, or focus items

Use cases of Vigil

Prevent agents from starting cold by providing full awareness in <1 second
Reduce token waste by loading only relevant tools per context mode
Coordinate multiple agents without requiring them to be in the same process
Automatically extract and persist recurring knowledge from agent signals
Trigger external actions (Slack, webhooks) based on signal patterns
