Ctxl
Run the ctxl npm MCP server to manage personal assistant context locally alongside Claude Code or Cursor.
Overview
ai.autoblocks/ctxl is a MCP server for the Build phase that runs local personal context management for AI assistants via the ctxl npm package.
What is this MCP server?
- Same Autoblocks personal context product as @contextlayer/mcp under package name ctxl
- npm registry package ctxl v0.0.2 with stdio MCP transport
- Source repository github.com/autoblocksai/ctxl
- Local process model for privacy-conscious solo builders
- Early 0.0.x release—pair with pinned versions in mcp.json
- npm package ctxl version 0.0.2
- Transport: stdio
- Repository: github.com/autoblocksai/ctxl
What problem does it solve?
Switching between agent tools or chat threads wipes the informal memory you built about your product and coding style.
Who is it for?
Builders whose MCP setup already references the ctxl npm package name from Autoblocks examples or older configs.
Skip if: Users who need the latest 0.0.3 scoped package features and should install @contextlayer/mcp instead, or teams wanting hosted team knowledge bases.
What do I get? / Deliverables
Installing ctxl stdio MCP gives your agent a maintained personal context layer you can update as the project evolves.
- Running local ctxl MCP context server
- Agent-accessible personal context store
- Documented stdio integration in mcp config
Recommended MCP Servers
Journey fit
Listed under Build as the primary install moment for agent memory tooling, even though context helps later in Grow support and Operate iteration. Agent-tooling captures MCP servers that extend how the assistant remembers you, distinct from backend APIs or shipping test harnesses.
How it compares
Legacy-style npm name for the same ctxl repo as contextlayer-mcp—not a separate context product.
Common Questions / FAQ
Who is ai.autoblocks/ctxl for?
Solo AI-coding workflows that follow Autoblocks ctxl documentation and install the unscoped ctxl npm MCP server locally.
When should I use ai.autoblocks/ctxl?
Use it during agent stack setup in Build when you want stdio personal context and your guide specifies the ctxl package rather than @contextlayer/mcp.
How do I add ai.autoblocks/ctxl to my agent?
Install npm package ctxl (0.0.2), add a stdio MCP server entry in Claude Code or Cursor per github.com/autoblocksai/ctxl README.
