"Relay" matching MCP servers:

Enables AI agents to operate a US power-grid data pipeline – ingest, plan, run, and monitor datasets like CAISO, ERCOT, and EIA-930 through MCP tools that mirror the CLI.

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 AI agents to access a unified catalog of tools from various APIs (OpenAPI, GraphQL, MCP, Google Discovery) through the MCP protocol.

A message relay MCP server enabling two separate Claude Code instances to exchange direct questions and answers asynchronously without sharing context.

Enables real-time communication between Claude Code instances across multiple machines via WebSocket, allowing context sharing, task handoffs, and coordination between sessions.

Enables AI agents to query locally stored Samsung Health data—such as heart rate, sleep, steps, and workouts—through MCP tools for samples, daily summaries, and trend analysis while keeping everything on your own network.

Enables turning spoken household issues into evidence-linked maintenance cases, deterministic diagnostic plans, quote comparisons, and owner-approved but unexecuted action proposals.

Provides cross-chain bridge and swap tools for AI agents using the Relay Protocol to interact with multiple blockchain networks. It enables agents to query supported chains, obtain transaction quotes, and generate unsigned transaction data for token transfers and swaps.

Open Task Relay provides free, bounded public-good tasks that autonomous AI agents can discover, complete, submit, and independently verify. Its public TypeScript source runs locally with a Cloudflare Workers-compatible runtime and SQLite/D1, exposing MCP over HTTP.

Security-enhanced MCP Relay/Proxy server providing real-time AI threat protection for MCP Clients, scanning tool descriptions, call parameters, and responses for threats like prompt injections and malicious URLs.

MCP coordination primitive for multi-agent workflows. Lets multiple AI coding agents (Claude Code, Cursor, n8n, custom clients) discover each other and exchange messages and tasks via a shared SQLite-backed message bus.

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

Enables cross-chain bridging, multi-chain token swaps, and real-time pricing across over 50 blockchain networks using the Relay Protocol REST API. It allows users to browse thousands of tokens, generate quotes, and monitor transaction status directly through natural language.

An MCP server that enables remote observation and control of a Chromium browser via a WebSocket relay, supporting DOM, CDP, and native OS automation for local or LAN-based AI agents.

An MCP server for controlling KR-series relay controllers via serial, TCP, or UDP, featuring auto-discovery, relay control, and advanced PLC capabilities.

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

MCP server for Korean content mini-games, enabling AI agents to host and participate in quote guessing, word relay, actor relay, balance games, and daily challenges.

An MCP server that seats multiple LLMs as a council, letting your assistant query them in parallel or in sequence, relay answers for cross-critique, and merge conclusions within one conversation.

Cross-chain bridge aggregator MCP server for AI agents. Compares routes across LI.FI, deBridge, Relay, Across and Squid to find the best rate. Use when an agent needs to bridge or swap tokens between EVM chains, Solana, or Cosmos. The aggregator of aggregators.

Self-hosted webhook relay and tunnel with Noise NK encryption. Inspect requests, replay webhooks, trace AI pipelines, connect/disconnect tunnels — 13 MCP tools. No tokens or passwords needed.
