"Signal" matching MCP servers:

MCPL server that bridges Signal via signal-cli, exposing DMs and group chats as channels and providing signal_send and signal_react tools.

MCP server for Signal via signal-cli that enables sending and receiving messages, managing contacts and groups, and reacting over stdio.

An MCP server that runs developer tooling commands (tests, linters, etc.) and returns compact, grouped error summaries to AI agents, reducing token usage and context window pollution. It supports multiple adapters for different tools and provides tools like run_check, diff_runs, and get_log_slice for iterative debugging.

Provides live integrations with GitHub, Spotify, and blog RSS feeds to power a dynamic portfolio.

Publishes experimental MCP Events methods — events/list, events/stream, events/poll, and events/subscribe/events/unsubscribe with verified webhook delivery — so MCP clients can receive pushed notifications alongside a public website. Anonymous visitors appear as floating dots and can ping or send a short message of up to 200 Unicode code points to any chosen name, with no accounts, database, or persistent storage.

An MCP server that lets AI assistants propose sending Signal messages, but nothing is ever sent without explicit human approval.

MCP server that wraps a running signal-cli daemon's JSON-RPC API as MCP tools, enabling list contacts, groups, conversations, read and send messages, and react to messages on Signal.

Exposes MCP tools over Streamable HTTP that turn ranked Sygnal signals into voice-ready buyer-intent briefings with analyst verdicts, card and carousel payloads, and session state for a simulated Alexa+ experience. It also surfaces the next recommended action so a voice assistant can guide users through follow-ups, with fallback fixtures when the live signal feed is restricted.

Enables ChatGPT to list, create, update, pause, resume, and delete monitoring items in Signal Desk via OAuth-protected MCP tools, with support for periodic execution and Web Push notifications.

Enables MCP clients to connect to a privacy-first, self-hostable workout planning and training log, allowing coaching agents to preview and apply program changes while accessing training data through OAuth-protected endpoints.
