Release Notes: 8.3

DipDup 8.3 brings several important improvements to enhance developer experience and expand integration capabilities. This release focuses on AI-assisted development with the Model Context Protocol, improved package management with uv, and standardized code quality tools.

Model Context Protocol

MCP is an open protocol that standardizes how applications provide context to LLMs. It enables AI tools to access and interact with your indexer data in real-time.

In this release, we've added a built-in MCP server to DipDup. This allows AI assistants like GitHub Copilot, Cursor, and Claude to understand your project's structure, schema, and current state.

We've prepared a complete guide on integrating DipDup with MCP to help you:

• Configure and run the DipDup MCP server
• Connect popular MCP clients (Cursor, VSCode, Claude)
• Implement custom tools and resources specific to your project
• Access real-time indexer data and metrics

Improved uv support

The uv package manager support was introduced in DipDup 8.2 and has proven to be reliable and loved by developers.

In this release, we've enhanced the integration:

• The installer script and dipdup self commands now use uv tool instead of pipx for faster, more reliable installations.
• Default project templates are configured to use uv by default
• Better handling of dependencies and virtual environments

To switch to uv in existing projects, update your configs/replay.yaml and run dipdup init --force.

Standardized linting and formatting

We've improved the integration of code quality tools that were already part of our default project templates. The key changes include:

• Replacing Black with Ruff Format as the default formatter for faster and more consistent results
• Better integration of linting and formatting tools with unified configurations (run on dipdup init)

Our carefully selected ruleset helps maintain code quality without being too restrictive. Check pyproject.toml and adjust it to your liking if needed. We continue to invest in standardized tooling because developer time is the most valuable resource.

If you prefer to manage code quality tools manually, you can disable the built-in linting with DIPDUP_NO_LINTER environment variable or dipdup init --no-linter option.

Migrating from 8.2

Existing projects will continue to work with 8.3 without any modifications.

If you want to use recent improvements like the MCP server, uv package manager, and Ruff formatter, refresh your project template:

dipdup init --force
make install

This will update your project package with the latest template files while preserving your existing code (handlers, models, etc.). The -b flag tells DipDup to update the project base template, and -f forces the regeneration of supporting files.

Changes since 8.2

Added

• cli: Added init --no-base option to skip creating the base template.
• cli: Apply ruff linting and formating on init.
• config: Added api_url and compatibility fields to MCP config.
• env: Added DIPDUP_NO_BASE environment variable to skip creating the base template.
• mcp: Added Model Context Protocol (MCP) server implementation.
• mcp: Added ctx.api datasource and ctx.call_api helper to server context.
• mcp: Added built-in resources for accessing indexer configuration and metrics.
• mcp: Added support for exposing custom tools and resources via @dipdup.mcp decorators.

Fixed

• api: Fixed configuring uvicorn logging.
• api: Strip secret fields from API responses.
• cli: Fixed new command using incorrect template.
