notte

Notte open-source web agent environment. It converts browser sessions into a Markov Decision Process with structured observation/action spaces, making browsers first-class RL and LLM agent environments.

infisical-agent-vault

A HTTP credential proxy and vault for AI agents like Claude Code, OpenClaw, Hermes, custom agents + harnesses, and more.

e2b-desktop

E2B Desktop Sandbox: a cloud virtual desktop (Ubuntu + VNC) with Python SDK for screenshot, mouse, keyboard, and process control; designed for AI agents that need a full GUI environment in an isolated VM.

agent-e

Emergence AI agent-E browser agent: hierarchical LLM-based web automation that uses DOM distillation and action abstraction layers to achieve significantly higher benchmark accuracy than prior browser agents.

letta-ai-agent-file

Use when you need to save, share, version or move a whole agent — its persona, memory and behaviour — as one portable file.

webvoyager

Research browser agent from Zhejiang University and HKU. It uses GPT-4V interleaved screenshot + HTML observations to complete open-ended web tasks; established an early web-agent benchmark (WebVoyager).

surf-computer-use

E2B Surf: a Stagehand-powered computer-use interface layer for E2B Firecracker sandboxes; connects the act/extract/observe primitives directly to microVM display output for lightweight headless computer use.

modal-labs-modal-client

Modal — serverless GPU/CPU containers for running agents, sandboxes and model inference from Python (this is the client SDK).

unicity-aos-capsule-identity

Use when an agent's identity must be persisted as state and assembled into its system prompt at boot, rather than pasted into a prompt by hand.

agntcy-oasf

Use when agents must describe themselves to other systems in a common schema so they can be catalogued, discovered and verified.

telagod-code-abyss

Use when you want a coding agent to have a consistent, composable personality and voice across Claude Code, Codex, Gemini CLI and OpenClaw.

agntcy-dir

Use when agents and multi-agent systems need to announce themselves and be found across organisations rather than hardcoded.

character-card-spec-v2

Use when reading or writing the character-card files that the roleplay-agent ecosystem actually ships, including the PNG-embedded variant.

cloudflare-web-bot-auth

Use when a website has to be able to tell that a request really came from your agent and not from someone impersonating it.

highflame-ai-zeroid

Use when a fleet of autonomous agents needs issued identities with a lifecycle — created, rotated and revoked.

agentmail-to-agentmail-toolkit

Use when an agent needs its own email address so people and systems can reach it, and it can act on what arrives.

agntcy-identity

Use when agents, MCP servers and multi-agent systems all need issued identities that another party can verify.

character-card-spec-v3

Use when authoring an agent persona against the current character-card standard, with lorebooks, assets and decorators.

agentrhq-authsome

Use when agents must stay logged in to third-party services without ever seeing your credentials.

gebruder-wirken

Use when autonomous agents need one gateway that holds their credentials, isolates them per channel, and logs every session.

opena2a-agent-identity-management

Use when non-human identities need the same lifecycle a workforce IAM gives people — issue, authorize, audit, revoke.

vestauth

Use when an agent needs to authenticate as itself to services, without you hand-rolling keys and rotation.

vorim-ai-labs-vorim-mcp-server

Use when you want agent identity, scoped permissions and an audit trail exposed to the agent as tools it can call.

deeptrail-deepsecure

Use when agents move from prototype to production and their identities, secrets and access need managing centrally.
