How to use

This MCP server is a Deno-based implementation for the Jotai MCP package. It runs the jotai-mcp-server using Deno with environment and network access enabled, sourcing the server bundle from the npm:jotai-mcp-server entry. The server exposes the MCP interface for interacting with Jotai-related functionality and provides access to accompanying resources such as a readme from the official repository and a tips collection (the latter being available to sponsors). To use it, ensure Deno is installed and start the server with the configuration that includes the jotai-mcp-server entry. Once running, clients can request the MCP endpoints defined by the jotai-mcp-server package and reference the included resources as needed.

How to install

Prerequisites:

Step-by-step:

  1. Install Deno on your system according to the official guide.
  2. Create the MCP config file (examples below) to define the jotai-mcp-server.
  3. Start the MCP server using your MCP orchestration tool, pointing to the config that includes the jotai-mcp-server entry.

Example: Create a config file named mcp_config.json with the contents shown in the mcp_config section of this document, then run your MCP orchestrator to load that configuration. If you run manually, the equivalent CLI invocation mirrors the args provided: deno run --allow-env --allow-net npm:jotai-mcp-server

Prerequisites recap:

  • Deno installed and accessible in your PATH
  • Access token (GITHUB_PERSONAL_ACCESS_TOKEN) if your setup requires authenticated access to GitHub resources
  • Network access for deno to fetch dependencies

Additional notes

Tips:

  • The environment variable GITHUB_PERSONAL_ACCESS_TOKEN is optional for public resources but may be required for private or rate-limited endpoints. Provide a token if you encounter authentication-related errors.
  • The server is configured to run with Deno's --allow-env and --allow-net permissions; ensure these are acceptable for your deployment environment.
  • If you upgrade jotai-mcp-server or related dependencies, verify that the npm entry npm:jotai-mcp-server remains valid and that the config’s command and arguments are compatible with the new version.
  • The README references a readme resource from the official repository and a sponsor-only tips section; these are informational and may not always be available in all deployments.
