Notes
Keep one note store synced across Claude, ChatGPT, Cursor, Codex, and Windsurf so context survives client switches.
Overview
io.github.mctx-ai/notes is an MCP server for the Build phase that centralizes notes across major AI coding clients via notes.mctx.ai.
What is this MCP server?
- Centralized note store explicitly supporting Claude, ChatGPT, Cursor, Codex, and Windsurf
- Remote MCP server (SSE) at https://notes.mctx.ai/v1.5.4
- Save in one AI client and retrieve from another without copy-paste chains
- Website https://notes.mctx.ai for account and setup context
- Version 1.5.4 documented in MCP server metadata
- Server version 1.5.4
- 1 remote endpoint (SSE): https://notes.mctx.ai/v1.5.4
- Explicit client support named: Claude, ChatGPT, Cursor, Codex, Windsurf
What problem does it solve?
Solo builders lose context when they switch between Claude, Cursor, and ChatGPT because each client keeps its own ephemeral scratch space.
Who is it for?
Indie builders juggling multiple AI tools daily who need one lightweight shared notebook for decisions, snippets, and checklists.
Skip if: Teams that require self-hosted wikis, granular RBAC, or deep Notion-style databases with offline-first guarantees.
What do I get? / Deliverables
Notes gives every connected agent the same MCP-backed note store so saved context follows you across clients and phases.
- Shared notes readable and writable from multiple AI clients
- Reduced copy-paste when moving between Claude, Cursor, Codex, and Windsurf
- Configured notes.mctx.ai v1.5.4 MCP remote in your toolchain

Journey fit
PM in Build is the canonical home for cross-cutting task and context management, though notes are equally useful from Idea research through Operate iteration. The pm subphase captures planning artifacts, decisions, and scratch context that agents should reuse across sessions and tools.
How it compares
Cross-client notes MCP sync, not an on-repo documentation skill or game/experience server.
Common Questions / FAQ
Who is io.github.mctx-ai/notes for?
It is for solo builders and small teams who use several AI assistants and want a single note layer accessible through MCP everywhere they work.
When should I use io.github.mctx-ai/notes?
Use it whenever you need durable scratch context—scope decisions, API keys reminders (non-secret pointers), launch lists—that must survive switching between Claude, Cursor, Codex, Windsurf, or ChatGPT.
How do I add io.github.mctx-ai/notes to my agent?
Configure the SSE remote https://notes.mctx.ai/v1.5.4 in each MCP client’s server list per https://notes.mctx.ai, authenticate if prompted, then use the server’s note save and search tools from chat.
