Longhand
Give Claude Code persistent local semantic memory across sessions without paying for recall API calls.
Overview
Longhand is an MCP server for the Build phase that provides local semantic memory and session-history recall for Claude Code with no recall API calls.
What is this MCP server?
- Local semantic recall across Claude Code session history
- Zero external API calls for memory retrieval (on-machine emphasis)
- PyPI package longhand v0.5.5 with uvx runtime hint and stdio transport
- Positional package argument mcp-server for stdio MCP launch
- MCP memory layer—not a cloud vector DB subscription or generic notes skill
- Package version 0.5.5
- Transport: stdio
- Registry: PyPI (longhand)
Community signal: 10 GitHub stars.
What problem does it solve?
Claude Code sessions forget prior decisions and you do not want cloud memory APIs or manual copy-paste archaeology every time you resume work.
Who is it for?
Indie developers on Claude Code who want private, local continuity across long agent sessions.
Skip if: Teams needing shared org-wide knowledge, compliance-audited cloud memory, or builders not using MCP with Claude Code.
What do I get? / Deliverables
After registration, the agent can semantically search local session history through MCP so multi-day solo builds stay coherent without extra API spend.
- Running stdio MCP server from longhand package (mcp-server entrypoint)
- Semantic search and recall tools over local Claude Code session history
Recommended MCP Servers
Journey fit
Long-running agent work happens in Build when you extend Claude Code with tooling; memory is foundational agent infrastructure, not a launch or growth tactic. Agent-tooling is the right shelf because the server adds recall over session history to the coding agent itself.
How it compares
Local agent memory MCP server, not a hosted RAG platform or documentation generator skill.
Common Questions / FAQ
Who is io.github.Wynelson94/longhand for?
It is for Claude Code users who want local semantic memory across sessions without relying on external recall APIs.
When should I use io.github.Wynelson94/longhand?
Use it during Build when agent sessions are long or span days and you need the coding agent to remember prior context on your machine.
How do I add io.github.Wynelson94/longhand to my agent?
Install the longhand PyPI package (uvx with mcp-server as documented), add the stdio MCP server entry to Claude Code, and restart so memory tools are available.
