"Relay" matching MCP servers:

Enables AI to delegate boilerplate, drafts, tests, and refactors to free LLM providers, saving tokens and running tasks in parallel.

Lets AI agents exchange typed, schema-validated messages and coordinate asynchronously through a shared inbox, with tools to list, ask, send, and reply to other agents.

MCP server that enables AI agents on different machines to communicate and collaborate directly through relay channels, supporting structured agent contracts, real-time messaging, and human-in-the-loop approval workflows.

An MCP server enabling AI agents to browse, claim, submit, and manage paid tasks on the SYNAI Relay agent-to-agent task protocol, with on-chain USDC settlement via x402.

Enables agents to discover services and check API contracts via tools like directory search, API Doctor, and receipt verification, without requiring an account or payment.

Enables team members' personal AI agents to exchange tasks, questions, decisions, and deliveries over MCP with identity, policy, and audit, using Slack as a shared visibility record.

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.

Forwards Instagram reels to Claude with timestamped transcripts and video frames, enabling Claude to watch, research, and build based on shared content.

MCP server connecting AI agents to SocioLogic's synthetic persona platform for interviewing personas, running research campaigns, and exporting reports.

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.

MCP server that enables controlling a StackChan robot via tools like speak, emote, and move head, with a relay service for ESP32 long polling.

An end-to-end encrypted inbox where AI agents deliver reports, files, and artifacts, and submit outbound email or spend requests for human approval. Content is decrypted in the browser, never on the server.

Enables image generation and editing through a configurable relay image API, with explicit parameters, original image preservation, and technical verification of output dimensions and transparency.

MCP client for AgentRelay, enabling local Codex agents to communicate with an AgentRelay HTTP relay for agent orchestration and task management.

Enables managing Firefox Relay masks (random and domain) via MCP tools, including listing, creating, updating, and disabling masks.

An AI operations agent that reads from your own PostgreSQL database and policy documents, provides grounded answers with citations, and exposes read-only tools to external MCP clients while keeping writes behind a human approval gate.

Enables external AI applications to access MCP tools by providing a user-hosted HTTPS endpoint that forwards requests to a paired desktop client.

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.

Exposes provider-specific tools and relays HTTP requests to configured providers like Supabase, Vercel, and Context7, enabling interaction with multiple external APIs through a unified MCP interface with configurable authentication and access controls.

Fetches images from allowed hosts (e.g., Hugging Face Spaces) and returns them as inline content to Claude, bypassing the sandbox's network restrictions.
