"Overview of HTTP (HyperText Transfer Protocol)" matching MCP connectors:

Official Kudosity Model Context Protocol (MCP) server that allows AI-powered editors (like Cursor and Windsurf) and assistants (like Claude Desktop) to directly explore and execute Kudosity APIs. With MCP, your AI can search API specs, generate code snippets, and run live requests; all without leaving your development environment.

Read-only public statistics for Telegram groups tracked by Limzo (https://limzo.com), a group analytics bot. Two tools: get_global_stats (network-wide totals) and get_group_stats (activity, engagement, top members, achievements for a group by its public slug - the last part of its https://limzo.com/s/<slug> URL; browse https://limzo.com/groups/ to find groups). Privacy-safe: payloads never include verbatim member messages. No authentication required. Docs: https://limzo.com/docs/

Multi-tenant Telegram gateway for AI agents — HTTP+stdio, 8 tools, MTProto User API

Print and physically mail letters and postcards to US addresses via USPS, including certified/registered mail and address verification. Paid per call in USDC on Base via the x402 protocol, no signup.

Ephemeral REST chatrooms where AI agents of different owners coordinate on a shared task. A room is one URL — no SDK, no registration; the owner watches the conversation live in a browser. Optional LLM arbiter turns negotiations into a tamper-evident Ed25519-signed ledger.

Bluesky MCP — wraps the AT Protocol API

The Telnyx MCP server is an official implementation of the Model Context Protocol that enables AI clients (like Claude Desktop, Cursor, and OpenAI Agents) to interact with Telnyx's telephony, messaging, and AI assistant APIs. It provides comprehensive capabilities including making and managing phone calls, sending SMS/MMS messages, purchasing and configuring phone numbers, creating AI assistants with custom instructions, managing cloud storage buckets, scraping and embedding website content, and handling integration secrets. The server exists as both a local implementation and a remotely hosted version, allowing developers to integrate real-world communication infrastructure directly into AI applications.

aX is an agent-native collaboration network. A single Streamable HTTP MCP endpoint gives agents persistent identity, real-time messaging with @mentions and threads, tasks and handoffs, shared workspace context, semantic search, agent discovery, and rendered MCP App / widget artifacts that humans and agents can open and play back.

Phone, SMS & email for AI agents. One remote MCP server (Streamable HTTP, OAuth or API-key auth, no local install) exposing call, sms, email, and event tools; also usable via CLI, Python SDK, and OpenAPI. Self-hostable, AGPLv3.

Reply.io is a sales engagement platform used by thousands of B2B sales teams to automate multichannel outreach — email, LinkedIn, calls, SMS, and WhatsApp. The Reply.io MCP server exposes the platform's core functionality as tools that any MCP-compatible AI model can call directly. The MCP server is hosted by Reply.io and authenticated via API key. No self-hosting or open-source setup is required.

Privacy-first agent inboxes: read, search, draft, send, and triage mail over Streamable HTTP.

Choir management for AI assistants: events, RSVP, announcements and sheet music of your choir.

Hosted NeuroDock — stateless communication and planning tools over OAuth-secured Streamable HTTP.

A Remote MCP Server that checks every email before your agent acts on it. Connect via MCP protocol, pay per use with Skyfire.

Continuity protocol for autonomous AI agents. Agent messaging with SMTP bridge and LN payments.

MCP server enabling AI agents to manage Bitrix24 features via standardized protocol

The file protocol for AI agent context — encrypted, signed, P2P messaging via plain files. No SDK required. Works with Claude, GPT, Gemini, any model. MCP server included. npm + crates.io.

Zapier MCP connects AI tools like Claude, ChatGPT, and Cursor to over 8,000 apps and 30,000+ actions, enabling AI to perform real-world tasks such as sending messages, searching data, scheduling events, and updating records. It acts as a translator between AI tools and apps, handling authentication, rate limits, and retries automatically, transforming AI from a conversational tool into a functional extension of your business stack.
