Existence Synchronization System Entity

VeniceEsse

MCP server that fuses 2–5 AI agents into one unified mind. Features 7 tools: esse_quick, esse_fuse, esse_execute, esse_list_agents, esse_list_sessions, esse_memory, esse_defuse. Supports Venice AI, OpenAI, and Anthropic. One AI. Many agents. Fused.

Ephemeral verification receipts for agent workflows. Agents create receipts to prove actions happened, then other agents verify before acting. Prevents duplicates, stale approvals, and unsafe retries. Receipts expire in 24 hours. Free API — sign up with the signup tool.

Codex Octopus

xiaolai

One brain, many arms. Spawn multiple specialized Codex agents as MCP servers via the OpenAI Codex SDK. Each instance gets its own model, sandbox, effort, and personality.

93 agentic MCP tools + 49 specialist agents for every major AI CLI. Self-learning, no API keys.

Ephemeral REST chatrooms where AI agents of different owners coordinate on a shared task. A room is one URL — no SDK, no registration. The owner creates a room, hands the URL to agents, and watches the conversation live in a browser. Remote MCP server at https://roomcomm.ru/mcp (

X402 A2a Hub

garyedgington

A discovery hub for AI agents navigating the x402 micropayment ecosystem. A single get_capabilities call returns the full service manifest — endpoint URLs, supported input/output formats, x402 payment details, and free trial endpoints for every live agent in the network. Use this

MCP Playground

Core MCP Server with React Frontend and Multi-Agent Support

Attestor

bolnet

Audit-grade memory backbone for agent teams. Bi-temporal facts (event time + transaction time, with recall(as_of=...) replay), 6-step deterministic retrieval (no LLM in the critical path), conversation ingest with speaker-locked dual-pass extraction, per-tenant Postgres row-level

Share one memory store across all your AI coding tools. Memory Arbiter is a lightweight, fully local MCP Server with built-in dual-timeline conflict arbitration. No cloud, no LLM calls — just SQLite.

Atomic gap-free id claims, advisory file leases, a shared event ledger + digest, presence, prose handoffs, and a task graph - so multiple agents (Claude Code, Cursor, Codex) stop colliding and re-deriving each other's work. Native Streamable HTTP, one claude mcp add. Open source

Runtime security oracle for AI agents — scan prompts, tool calls, and outputs before execution. Pay-per-call via x402/USDC, no accounts needed.

A neutral, attack-resistant reputation and trust layer for autonomous AI agents. Agent Guild lets an agent ask "who is the safest agent for this job?", vet any agent before delegating work or money, and vouch for completed work with cryptographically signed attestations. Reputati
