"A server that supports Server-Sent Events (SSE)" matching MCP servers:

Turns ordinary third-party provider webhooks, starting with Resend inbound email, into MCP Events that agents can subscribe to and act on. Hookdeck Event Gateway verifies, stores, filters, dedupes and retries delivery to each subscriber's callback, while the server exposes event catalog, subscribe/unsubscribe, and past-event lookup tools.

Enables querying and triaging SEC 8-K events through a pre-classified mirror.

Implements a Model Context Protocol server using Server-Sent Events for real-time communication with OAuth 2.1 integration via Ory Network, enabling secure AI model communication with authentication and client management.

Enables AI assistants to manage events, venues, organizers, and tickets on WordPress sites via CRUD operations.

Enables agents such as ChatGPT to subscribe to events happening behind an MCP server (for example, order.created with filters) and receive them as signed webhooks without the builder implementing delivery itself. Hookdeck Outpost handles filtering, Standard Webhooks signing, retries, and delivery to each subscriber's callback URL.

Enables creating and managing webhook subscriptions for blockchain events such as new blocks, confirmed transactions, and token transfers across major blockchains (EVM, UTXO, Solana, XRP).

MCP server that provides live event search, explainable recommendations, night planning, and agentic ticket purchase with safety rails, using Dizko's event inventory.

MCP-first A/B testing server that enables agents to manage experiments (create, update traffic splits, read results, apply winning variants) from tools like Claude Code, with self-hosted Cloudflare backend.

Enables teams to automate certificate issuance and query engagement data from the thatsme platform via AI-powered tools like search_events and issue_certificates.

Universal HTTP 402 Micropayment Protocol & Autonomous Economic Settlement Engine for AI Agents on Base L2.

Answers why a specific number in a Chinese listed company moved — margins, cash flow, inventory, management commentary, policy impact — by reading filed reports and IR transcripts and returning figures with the document and announcement number attached. It deliberately refuses price, valuation, and recommendation queries, returning a "gone_by_design" error instead.

Enables searching and retrieving content, module information, and Twig template snippets from a-blog cms via its GET API.

Lets an AI assistant read call and message history, send texts and picture messages, reach Phone Book contacts by name, and — once switched on — place calls run by a voice agent, all limited to the phone numbers the user ticks. Hosted remotely with OAuth sign-in, so nothing needs to be installed locally.

A server that interfaces with the Hedera Testnet Mirror Node API, converting its OpenAPI-defined endpoints into MCP-compatible tools that can be accessed over Server-Sent Events (SSE).

Enables an assistant to send email and list sent emails through the Maillog email API.

Just to be clear about the final JSON: the MCP server is named herdr-inbox, and it enables Claude Code agents in herdr to ask questions asynchronously without stalling, with all open questions answered from one popup and answers routed back to the asking agent.

Enables AI assistants to manage CData Sync operations, including data synchronization jobs, connections, and ETL processes through stdio or HTTP transports. It provides tools for executing jobs, monitoring real-time progress via Server-Sent Events, and handling comprehensive workspace configurations.

Connects MCP clients to a local browser-based map editor, enabling session discovery, map state inspection, item and actor queries, actor placement and movement, selection changes, deletion, and undo/redo operations. Supports STDIO, Streamable HTTP, and legacy HTTP+SSE transports through a local WebSocket bridge.

Enables deploying a secure MCP gateway that proxies, sandboxes, and policy-governs third-party MCP servers, with credential vaulting and audited tool access across stdio, SSE, and Streamable HTTP.

Loads multiple MCP tools as plugins, enables management via a web dashboard, and serves them over HTTP with Server-Sent Events.
