keryx vs notion-mcp-server

keryx: Keryx is a fullstack TypeScript framework built on Bun, designed to write application logic once and deploy it across various transports, including HTTP, WebSocket, CLI, background tasks, and MCP (Model Context Protocol) for AI agents. It automatically exposes all actions as MCP tools, allowing AI agents to authenticate and interact with your application's validated endpoints with type safety.; notion-mcp-server: This project provides a local Model Context Protocol (MCP) server for the Notion API, offering powerful tools specifically designed for AI agents to interact with Notion content efficiently. It supports various client integrations and deployment methods, enabling AI to manage Notion pages and data sources.

When to choose:
  • You want a local Notion server you run with npx or Docker, using an internal integration token.
  • You want access limited to the pages and databases you connect to the integration, or a read-only token.
  • Your prompts work with Notion API data sources: v2.0 has 21 tools on the 2025-09-03 API.
When to skip:
  • You want the supported option: the README says Notion prioritises its remote Notion MCP and may sunset this repository.
  • You need issues answered: the README says issues and pull requests here are not actively monitored.
  • You do not want to manage tokens: the remote Notion MCP uses standard OAuth instead.

Features

keryx logokeryx
01MCP-native actions: Every action is automatically an MCP tool with OAuth 2.1 authentication, typed errors, and per-session isolation for AI agents.
02Transport-agnostic Actions: A single action class handles HTTP, WebSocket, CLI, background tasks, and MCP tool calls with unified validation and middleware.
03Zod input validation: Provides type-safe parameter validation with automatic error responses and OpenAPI generation.
04Built-in background tasks: Utilizes node-resque for background job processing with fan-out patterns for parallel execution.
05Strongly-typed frontend integration: Offers end-to-end type safety for API responses with a companion Vite + React frontend, no code generation needed.
06Streaming responses: Supports SSE, chunked binary, and cross-transport streaming behavior for real-time data flow.
