"A system or program using SSE instead of STDIO" matching MCP servers:

A simple MCP server implementation in TypeScript that communicates over stdio, allowing users to ask questions that end with 'yes or no' to trigger the MCP tool in Cursor.

Enables AI agents to query OpenRouter model information including prices, ELO rankings, context, and perform comparisons.

A minimal, zero-dependency MCP server that enables defining and running tools over stdio transport, without extra features like HTTP or resources.

Enables authenticated users and service accounts to discover and invoke tools from a wrapped third-party stdio MCP server behind a secure gateway, using per-profile credentials, role/default routing, and managed child instances.

MCP server for Jira integration with stdio transport. Enables reading, writing, and managing Jira issues and projects directly from Claude Desktop. Supports issue creation, updates, comments, JQL search, and project management.

Stable stdio MCP server for Google Stitch AI UI design tool, eliminating the proxy subprocess to prevent crashes. Provides tools to manage projects, screens, design systems, and generate UI designs.

A local Model Context Protocol server (stdio) for Redmine that allows you to work with Redmine issues, projects, and time entries directly from your editor.

A development tool that serves as a bridge to launch and inspect other stdio MCP servers on demand, ensuring a clean process for every operation. It enables developers to bypass host caching issues by providing tools to list and call target server components during active development.

A no-nonsense framework for building stdio MCP servers using plain async handlers and type annotations, with strict schema validation and no configuration overhead.

Acts as a proxy between a local Stdio connection and a remote Model Context Protocol server running over Server-Sent Events. It specifically enables Stdio-based MCP clients to connect to the SwiftZilla remote SSE endpoint.

Local stdio proxy for Uno MCP Gateway that enables MCP clients without OAuth support to securely connect to authenticated remote servers.

Supply chain risk scoring for npm, PyPI, and GitHub repos

A Model Context Protocol server that exposes an airline design system as a queryable knowledge base, enabling AI to discover components, find components for use cases, and scaffold prototypes.

Enables MCP clients to evaluate typed choice, score, and noul questions and list available models on configured backends such as Ollama nimble/tev/clef, TypeSafe jev, Kev, or Laya via two stdio tools.

Enables MCP clients to call a single identify tool that returns fixture name, version, transport, and a supplied message for publisher acceptance testing. It runs over stdio without external services or credentials.

reference MCP server over STDIO — every SDK feature demonstrated

A FastAPI MCP server that uses Server-Sent Events as a transport layer, providing echo functionality through tools, resources, and prompts.

Exposes any stdio-based MCP server over the MCP Streamable HTTP transport so remote clients can reach it, spawning an isolated child process per session and gating access behind a secret URL path.

Creates a local MCP runtime for design-system repositories, enabling AI coding agents to look up and use real components, icons, and tokens instead of guessing.

A starter MCP server using StdioServerTransport, providing example tools to check which app runs on a port (macOS) and add two numbers.
