"Relay" matching MCP servers:

Enables explicit, auditable project-context handoffs between ChatGPT Work and Codex through nine MCP tools for upserting projects, creating handoffs and checkpoints, and retrieving project context and history.

Enables Alexa+ agents to maintain auditable operational continuity across shifts by turning speech into verifiable state, persisting unresolved work, refusing unverified actions, and requiring human approval before executing and confirming high-risk tasks.

Read-only MCP access to the p-e relay store: an append-only corpus of provenance-bearing coordination records, with tools to fetch a record by id, list records and replies, and check existence. This image serves a snapshot frozen at build time; append_relay is listed but refused, and deposits to the live store require an HMAC-signed request.

Enables selecting exact conversation excerpts, carrying forward only confirmed background and provenance, and handing the packaged selection to another agent for continuation.

Read, search, and write Obsidian vault notes via Team Relay collaborative server. Supports shared folders, real-time sync, and AI agent access.

A lightweight, self-hostable MCP server for shared memory, structured command relay, and traceable decision evidence across AI runtimes.

A global marketplace MCP server enabling OpenCode instances to publish, search, and exchange MCP server capabilities, knowledge, and ideas over a distributed network via SMTP relay.

Enables Claude Code with persistent semantic memory, cross-session context, and memory hygiene via a local AD4M executor, offering 13 tools for managing semantic graphs and cross-terminal relay.

Enables MCP clients to manage conversations, handoffs, context packets, audits, and publishing through the LNKZ REST relay, while exposing resources and prompts for context-aware workflows.

MCP server enabling ChatGPT to search, read, and write Apple Notes via a local Mac agent with a privacy-preserving relay.

Enables AI assistants to maintain continuous project memory by automatically relaying compacted context from any MCP compactor into a persistent context log.

MCP server that exposes hardware automation tools (build, flash, serial capture, symbolization, relay control) for ESP32-S3 boards, with board-level concurrency locks and remote access.

AI idea relay commons where agent outputs become permanent, buildable nodes in a knowledge graph via MCP.

Persistent, structured memory server for AI agents using the Model Context Protocol, with categorized storage and tools to add, get, delete, and list memories.

On Board is a local MCP server that gives multiple AI agents and IDEs a shared project memory, ticket queue, and handoff history, so agents can seamlessly continue each other's work. It supports agent-to-agent wake events, enabling autonomous workflows like reject-fix-resubmit cycles without human relay.
