"Agent Dilemma - Concept or Topic Search" matching MCP servers:

Enables Claude Code, Codex CLI and Antigravity (Gemini) agents to exchange messages that are pushed live into each other's open sessions, with mail_send, mail_check and mail_peers tools so no agent has to poll. Mail can also be bridged over SSH between machines with no shared filesystem.

Enables full-text search of macOS iMessages including link preview metadata. Works as an MCP server for Claude Desktop to search your messages locally.

Enables searching Telegram messages and chats, retrieving recent messages, and extracting text from attached documents (PDF, TXT, MD, CSV) using your personal Telegram account.

Enables coding agents to send files and notes into approved Zas channels and read items back, with content encrypted before leaving the machine and scoped, revocable agent access.

Enables an agent to hand a prepared natural-language task from its current conversation to a specified chat in a real client, then wait for and verify the recipient's actual accept, refuse, or clarification reply. Provides tools to locate or reuse a recipient conversation, stage and preview the transfer, supplement missing information, and report the genuine receipt back in the source chat while keeping all records in a local SQLite store.

Enables AI agent sessions to read, search, and post durable messages to a private local JSON-file message board, letting them share preferences, lessons, warnings, questions, and replies without a cloud service or database.

Lets independent Claude Code and Codex sessions running in different tools and projects discover each other and exchange questions, coordination messages, and replies that arrive back in the conversation that asked. Uses direct local Unix sockets between sessions on the same machine, with no extra service to run or account to configure.

Enables MCP-capable agents to search shared threads, retrieve full discussions, post sourced findings/questions/answers, and list channels or open questions so they can reuse prior findings and surface unresolved disagreements.

Enables AI agents to exchange private, asynchronous messages through a provider-verified store-and-forward mailbox, with tools to send, check inbox, acknowledge, read threads and block senders. Built on the SAMP protocol, it gives each agent its own key-based identity, structured message data, and automatic expiry so handoffs survive while recipients are offline.

Enables multiple MCP-connected AI agents to talk to each other in local, owner-controlled message rooms where each agent has its own identity for reading, posting, replying, and tracking unread messages. A browser UI lets the operator watch conversations live, create rooms, manage per-agent access, and step in as themselves without any cloud service or API keys.

Lets AI coding agents delegate work to each other through a shared broker: each agent can list peers and unread counts, send typed messages tied to a task id (questions, review requests, decisions), and read and clear its own inbox. Every exchange is recorded in an audit trail filterable by task, so parallel agents leave a reviewable record of who asked whom for what.

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.

Enables durable agent-to-agent messaging across any MCP client, DSH session, or A2A agent, with threads, receipts, search, broadcast, attachments, presence, SSE streaming, signing, and wake-on-message.

Enables any agent to send a message by name into a live chat or another agent's conversation, and to receive replies by long-polling an inbox cursor that yields each message exactly once, in order, in roughly a tenth of a second. Also lets agents discover reachable chats, threads, and registered agents, with unresolvable names optionally routed to a relay agent for delivery.

Exposes read-only tools over a local OneBot 11 / NapCat endpoint for a logged-in QQ account, letting agents list sessions, fetch chat history and surrounding context, resolve forwarded messages, search messages, and inspect files or media, with message sending gated off by default.

Enables AI coding agents running in separate apps to exchange messages, tasks, presence, and context through shared rooms, direct threads, and webhook wake-ups. A human owner stays in control by approving proposed plans before execution and reviewing posted results, with safety limits on agent-to-agent chatter.

A local MCP relay that enables two or more MCP-speaking agent CLIs to communicate through shared channels by posting and reading messages.

A local MCP server that lets Claude Code, Codex and Gemini agents post messages, mention each other, wait for replies without burning tokens, and share tasks that move from assigned to verified. It pairs with a local desktop window for writing tasks, following every conversation, monitoring agent models and quota, and sending owner-signed instructions.

Enables AI agents and applications to send audio notifications with text-to-speech, message streaming, agent-to-agent conversations, and web push notifications through a persistent message store and MCP integration.

Exposes a shared-directory message bus to coding agents as MCP tools: receive pending messages, send one-way announcements, ask a peer and block until answered, and track peer status. Lets agents read and update per-agent state and group announcement boards so several agents working on the same machine stay coordinated without a broker, port, or account.

Enables AI agents to exchange direct messages and post to channels, check inboxes with optional blocking waits, page conversation history with automatic size-capped summaries, and attach or retrieve files. It also supports channel membership, agent registration, and optional phone push notifications, hosted entirely on Cloudflare's free tier.

Enables AI agents to connect to the P-Talk civic discussion forum over MCP/stdio, synchronizing platform rules, reporting skill attestation, running health checks, and posting questions or replies as an AI agent using environment-provided credentials.

Enables one AI coding agent to discover, read, message, and wait on other agent sessions across Codex threads and Claude Code or Claude Desktop sessions, while logging every send as a local receipt that can be audited later.

A self-hosted WhatsApp bridge with an AI agent enabling searchable context, message drafting, and approval workflow via MCP protocol for Claude Desktop and other MCP clients.

MCP server that enables Claude Code to communicate with other Claude Code agents over HTTP, allowing users to ask questions about remote codebases or delegate coding tasks.

Enables searching and retrieving messages across Slack workspaces using Slack's search API. Supports pagination, filtered results, and returns message details including text, timestamps, users, channels, and permalinks.

Enables sending, reading, archiving, and threading messages across parallel Claude Code sessions with per-session addressing and status monitoring.

Agent-native cold-email infrastructure providing ~12 high-level tools for domain setup, mailbox provisioning, campaign launch, inbox management, and metrics, all operated via MCP or CLI.

Lets separate coding-agent sessions coordinate through a shared, role-addressed mailbox instead of a human relaying every message, over a single local SQLite file or a hosted server with many isolated channels. Messages can be sent as tracked obligations that stay open until one side resolves and the other confirms, alongside threads, full-text search, work statuses, and an append-only versioned pin system where protected changes require recorded agreement from every declared role.

Read-only MCP server for Agent Plaza (plaza.exiton.net). Provides plaza_get_manifest, plaza_get_digest_sample and plaza_list_residents using only the Python standard library.

Enables concurrent terminal sessions or other MCP clients on the same machine to register, exchange messages, check inboxes/replies, and coordinate tasks through file-based storage without a daemon or network port.

A public, long-lived contact and cooperation point for autonomous AI agents. Agents describe missing capabilities or resources, request help from a human operator, and leave persistent messages on a tamper-evident message board.

Enables AI coding agents to coordinate through a local, pull-only message board by registering sessions, posting updates, proposing and accepting tasks, holding leases, and reading or acknowledging updates under scoped human authorization.

Slack for AI agents — rooms, messaging and context sharing for multi-agent collaboration.

A Model Context Protocol (MCP) server for Discord-based AI agent-user communication. Enables AI agents to communicate with users through Discord instead of IDE chat interfaces.

MCP server that connects AI assistants to Instructure Canvas LMS, enabling teachers and administrators to manage courses, assignments, grades, and more through natural language.

Enables local AI sessions on the same machine to exchange messages through a hub using register, send, check, wait, and who tools, with an optional browser-based live log viewer.

Enables Claude and Codex sessions on the same host to communicate across different session systems via shared SQLite rooms, with named participants, durable ordered messages, offline delivery, and wait-based message handling.

A home for any agent on the internet: inbox, public memory, job board, rooms, human help. Free, no key.

Enables multi-agent collaboration across different AI assistants and projects by providing a universal coordination layer for MCP-compatible agents to communicate, share context, and coordinate complex tasks seamlessly.
