"Relay" matching MCP servers:

A keyboard-first API client that stores requests and environments as plain files, and exposes its workspace over MCP so agents can browse, send, and create requests with vault access.

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

Enables separate Claude Code sessions across a team to see teammates' live presence, warn before editing a file someone else is editing, route shared-contract changes to the developers whose code depends on them, and produce structured handoffs when a session ends.

Adds a human-in-the-loop checkpoint to MCP-capable AI coding agents, enabling them to pause and request user feedback before executing actions.

High-performance Model Context Protocol (MCP) server connecting Claude Code and AI agents to Google Gemini 3.8 Flash, Gemini 3.1 Pro, reasoning effort, and image generation.

Provides AI coding agents real-time browser access to console logs, network requests, DOM elements, and screenshots via MCP, enabling tight edit-reload-verify feedback loops.

Diagnoses the Codex MCP launch path and writes host configuration so Codex, Cursor, or Claude Code can spawn the dsh profile. It does not run the MCP stdio server in the Web process.

Enables running both Claude Code and Codex locally with a shared task board, session resume, cross-agent handoff, and an MCP bridge for inter-client messaging and task/context inspection.

Connects Claude Desktop and Claude Code, enabling autonomous exchange of messages, files, and code while keeping their context windows separate.

Self-hosted session relay for Claude enabling shared message threads across multiple Claude surfaces like Code, Chat, and Cowork, allowing seamless state transfer without manual copy-paste.

Enables developers to expose any dev tool as a safe, audited MCP server with permission tiers, audit logging, and automatic argument validation.

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

Enables coding agents to develop on one machine and verify results on another, using branch-bound runbooks, isolated checkpoints, and structured receipts to guide repair iterations.

Wraps local multimodal CLIs (Google Gemini CLI and Qwen CLI) as MCP tools, enabling text-only AI assistants like Claude to analyze images through relay calls. Supports local paths, URLs, and base64 image inputs with configurable models and output formats.

A persistent local MCP relay that caches tool discovery, keeps upstream servers warm, and allows agents to hot-add or refresh MCP servers through management tools.

A unified MCP gateway that reduces context token usage by exposing all services through just two tools (search and execute), supporting built-in services like Asana and Sentry as well as proxied external MCP servers.

Relay messages between Claude Code sessions over MCP without stealing window focus, enabling background communication between parallel sessions.

Enables MCP clients to connect to remote servers that have OAuth issuer mismatches (e.g., OutSystems) by relaying stdio and handling OAuth flows with optional issuer override.

A Docker-based relay service that simplifies authentication and provides audit logging for AI agents accessing IBM Guardium Cryptography Manager's MCP server.

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