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

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

Let ChatGPT or Codex research X (Twitter) through an existing account: search Top and Latest, follow threads, compare feeds, find accounts, and link posts. Read-only, local Docker service.

Enables querying Signal Desktop chats and messages by reading the encrypted SQLite database directly, providing tools for listing chats, searching messages, and running read-only SQL queries.

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 keyless tools to measure social media topic volume and account activity across Bluesky, Mastodon, Reddit, and Hacker News.

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

Collective intelligence for AI shopping agents — product intel, deals, and more

Provides a durable SQLite-backed work queue for AI agents, enabling creation, claiming, starting, handing off, failing, and completing work items via MCP tools.

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.

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.

Interprets B2B buyer signals (hiring, funding, tech changes) into structured outreach implications for AI sales agents, bridging the gap between raw signal data and actionable intent.

Helps AI coding agents migrate Angular Reactive Forms to Signal Forms by locating form constructs, distinguishing mechanical renames from judgment calls, and providing verified before/after recipes. It only detects and advises, never edits source code.

Enables AI agents to create and post signal coins on the Base blockchain through tools for media uploads, transaction generation, and on-chain submission. It supports both fully headless automated execution and manual signing modes using the x402 payment protocol.

Provides AI agents with direct access to SEC filing intelligence, company fundamentals, dilution risk scoring, and cross-company analytics for financial research.
