"Relay" matching MCP servers:

Enables local AI agents to communicate directly over Unix sockets, allowing multi-agent collaboration across different models and harnesses without any broker or network dependency.

MCP server that drives a user's real Chrome browser via a WebSocket-connected MV3 extension, enabling tab management, navigation, page interaction, screenshots, and script evaluation through natural language.

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.

Enables ChatGPT Plus and Codex agents to use DataRelay Link through a published Agent Plugins package, relaying tool calls to the upstream DRLink Server MCP for authorization and execution.

Agent tools for the Ophis intent-based DEX: parse, quote, build, relay orders, look up fee tiers.

Enables AI agents to manage account, usage, and abuse operations for the Volter tunnel relay.

Drives the browser you are already signed into, so work behind a login, SSO or MFA needs no scripted auth. A local stdio MCP server talking to the free T3rnel Browser extension over a native-messaging relay. 20 tools standalone; 99 with the extension — CSS-as-component export, full-page capture, React inspector, network and console capture, form filling, record and replay. Nothing hosted.

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.

Security intelligence for AI agents — breach detection, SIM swap, domain lookalikes, OAuth watchlist, and malware scanning. Subscription or x402 PAYG.

Runs commands on machines you cannot SSH into by publishing steps to a transport the far side already reaches (git, file share, S3, relay), then reads back a log with every line timestamped in UTC. Seven tools cover send, status, logs, stall detection and a pre-flight check.

Enables efficient AI workflow orchestration by chaining multi-step LLM operations while keeping intermediate results out of the context window, reducing token usage by 90%+ and supporting multiple AI providers.

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.

Enables CLI/agent sessions to join a Buzz relay, see channels, read the bus, post, and @mention agents, with custody-clean identity resolution.

Builds and edits real websites from your coding agent: create a site from a template, rewrite sections, add and link pages, insert blocks, keep reusable symbols in sync, screenshot any viewport, and export static HTML/CSS/JS. Drives an open Swebsy Studio tab in your browser over a local 127.0.0.1 WebSocket relay — no account, no API key, and no per-token AI fees.

A local MCP runtime that lets MCP clients such as ChatGPT inspect workspaces, search, read, write, and patch files, manage directories, run shell commands, and control persistent processes on your machine through an outbound Device Relay connection that needs no open inbound port. It can also publish a local loopback OpenAI-compatible model runtime as a Frely personal Provider.

Provides Solana RPC tools for agents to check health, estimate priority fees, sample Yellowstone gRPC, and submit signed transactions via the rpc edge relay.

Enables LLMs and MCP clients to interact programmatically with Flux, Volt, and Mesh simulation web applications via WebSocket relay.

Enables secure remote access to your computer's filesystem and terminal through MCP, allowing AI assistants to manage files, run commands, and automate tasks from anywhere via a hosted relay.
