What it does
Eve is a filesystem-first framework designed to enable durable backend AI agents that can persist state and run reliably across different environments. It provides infrastructure for building agents that interact with file systems as a primary data store, enabling stateful, long-running AI workflows.
Who it’s for
Backend developers and builders creating production AI agents that require durability, state persistence, and multi-environment deployment. Teams building autonomous systems that need reliable data handling and filesystem-based workflows.
Copy-paste setup
Check these steps against the project’s own instructions before running anything.
Install via npm:
npm install eve
For Claude Desktop MCP integration, verify against the repo README at https://github.com/vercel/eve.git (opens external site) for current mcpServers configuration. Typical setup involves configuring filesystem paths and agent parameters in your project's initialization code.
Risks
- Filesystem access scope: Agents granted broad filesystem permissions could read/exfiltrate sensitive credentials or private data from the host system
- State persistence vulnerabilities: Durable agent state stored on disk may expose conversation history, intermediate reasoning, or user data if storage isn't encrypted
- Prompt injection via file content: If agents read untrusted files and process them as prompts, malicious file contents could manipulate agent behavior
- Supply chain consideration: Early-stage project (0 GitHub stars) with high npm adoption warrants monitoring for maintenance and security updates
- Minimal versioning signal: Limited public visibility makes it harder to assess community scrutiny or disclosed vulnerabilities
How to stay secure
Eve MCP Connector Security Hardening Guide
Least-privilege permissions
- Restrict file access zones: Only grant eve permission to access specific folders it needs (e.g.,
/var/eve-data), not your entire system or sensitive directories like/etcor~/.ssh - Use dedicated user accounts: Run eve under a separate system user with minimal permissions rather than an admin or production account
- Disable write access where possible: If eve only needs to read certain files, explicitly remove its ability to modify or delete them
- Rotate credentials regularly: Keep API keys and passwords separate from eve's working directories; refresh them every 30-90 days
Network isolation
- Limit outbound connections: Configure firewalls to allow eve to communicate only with approved services it genuinely needs (not the full internet)
- Run in a sandbox or container: Use Docker, virtual machines, or OS-level sandboxes to isolate eve from the rest of your infrastructure
- Disable unnecessary network interfaces: Ensure eve cannot access internal networks or databases unless required for its specific job
- Monitor data egress: Log and alert on any large or unexpected data transfers leaving eve's environment
Monitoring
- Audit file access logs: Track which files eve reads and writes; alert if it accesses unexpected locations like credential stores or user home directories
- Encrypt stored conversations: Ensure agent state and chat history are encrypted at rest so even if disk is compromised, data remains protected
- Review agent behavior regularly: Periodically examine eve's decisions and file operations to spot unusual patterns or unauthorized activity
- Enable security update alerts: Subscribe to notifications for eve package updates and apply security patches within 24-48 hours of release
Red flags to watch for
- Unexpected file access: Eve suddenly reading files outside its designated directories or accessing system configuration files
- Large data transfers: Unusual amounts of data being uploaded, downloaded, or moved to unfamiliar locations
- Version abandonment: No updates to eve for 6+ months, unclear maintenance status, or unresponded security reports on GitHub
- Modified file contents: Changes to eve's configuration, state files, or injected content that could alter its behavior without authorization
