Cline v3.88.0 Adds Fireworks AI Kimi K2.6 as Default Model, Fixes MCP Server Management
Cline released v3.88.0 on June 5, 2025, changing its default Fireworks AI model to Kimi K2.6 and addressing critical bugs in MCP server configuration.
Key Changes
The update adds the latest Fireworks AI serverless models to Cline's model selection and sets Kimi K2.6 as the new default Fireworks model. Cline removed outdated Fireworks AI models and corrected model metadata and cache pricing information.
The release fixes a significant bug in MCP (Model Context Protocol) server management where delete and add operations would cause the file watcher to empty the entire MCP server list during settings writes. This bug prevented users from reliably managing their MCP server configurations.
Recommended Models Endpoint
Cline now uses the upstream Cline recommended models endpoint for all users, removing the feature flag that previously gated this functionality. This change means all Cline instances will now receive standardized model recommendations directly from the project's maintained endpoint.
What This Means
The switch to Kimi K2.6 as the default Fireworks model suggests the Cline team found it performs better than their previous default for coding tasks. Moonshot AI's Kimi models are known for their extended context windows and Chinese-English bilingual capabilities.
The MCP server fix addresses a critical workflow issue for users who integrate external tools and data sources through the Model Context Protocol. The bug could have caused data loss in server configurations, making this a significant stability improvement.
Removing the feature flag for the recommended models endpoint indicates the Cline team is consolidating their model recommendation infrastructure, likely to provide more consistent experiences across their user base and simplify testing of new model integrations.
Full changelog available from cli-v3.0.20 to v3.88.0.
