Walkthrough

This update introduces new development instructions in the documentation for running the MCP server locally, including details on enabling debug output with an environment variable. Development scripts in the package configuration are modified to automatically load environment variables from a .env file. The server implementation is updated to listen on all IPv4 interfaces by binding to "0.0.0.0". The @pipedream/sdk dependency is also updated to a newer version.

Changes

File(s) Change Summary
modelcontextprotocol/README.md Added a section with instructions for running the server locally, including debug mode usage and command examples.
modelcontextprotocol/package.json Modified dev scripts to load .env via -r dotenv/config and updated @pipedream/sdk version to ^1.5.2.
modelcontextprotocol/src/sse.ts Changed server to listen on "0.0.0.0" for accepting connections on all IPv4 interfaces.

Poem

Hopping through the code so bright,
Local servers now take flight!
With dotenv’s magic, configs appear,
Debug logs whisper, crystal clear.
On every port, connections grow—
A happy dev, a server in tow!

Chat

There are 3 ways to chat with CodeRabbit:

  • Review comments: Directly reply to a review comment made by CodeRabbit. Example:
    • I pushed a fix in commit <commit_id>, please review it.
    • Generate unit testing code for this file.
    • Open a follow-up GitHub issue for this discussion.
  • Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
    • @coderabbitai generate unit testing code for this file.
    • @coderabbitai modularize this function.
  • PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
    • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
    • @coderabbitai read src/utils.ts and generate unit testing code.
    • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
    • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

10-11: Improved developer experience with automatic environment variable loading!

Adding -r dotenv/config to the dev scripts enables automatic loading of environment variables from a .env file, making local development easier and more consistent with the new instructions in the README.


23-23: SDK version bump looks good.

Updating the @pipedream/sdk dependency from ^1.4.0 to ^1.5.2 ensures compatibility with the latest features and bug fixes.

163-163: Improved server accessibility by listening on all interfaces.

Binding to "0.0.0.0" allows the server to accept connections on all IPv4 interfaces instead of just localhost, making it more accessible for local development and testing from other devices.
