How to Use the AI21 Labs MCP in Cline

Q: Does AI21 Labs support conversational chat in Cline?

The ai21chatcompletion tool provides access to Jamba models for standard back-and-forth dialogue. Cline passes your prompt through the endpoint and prints the reply in your VS Code sidebar.

Q: What happens when I ask the agent to improve my writing?

The agent executes the ai21textimprovements command on your selected text. It evaluates the style, retrieves suggestions, and implements the edits in your current working document.

Perplexity

Automate documentation with Cline

Calling `ai21_summarize_text` allows the agent to read your messy commit history and generate a clean changelog. You ask for release notes, and the agent pulls the diffs, sends them to the API, and writes the output to a new markdown file. It does not stop at summaries. Cline uses `ai21_grammar_correction` to review your inline comments and fixes typos before staging the commit. You watch the diff appear in VS Code without typing a single correction.

Extract facts using the MCP Server

The `ai21_contextual_answers` tool forces the model to rely only on the provided background text. You feed it a massive API documentation file and ask how a specific endpoint works. Cline handles the extraction. If the source material is too dense, the agent runs `ai21_segment_text` to split the document into logical topics first. It writes the exact configuration steps into your project files based on the extracted answers.

Control remote files directly

Endpoints like `ai21_list_files` and `ai21_get_file` exposed by this MCP server let your AI client inspect the reference materials currently stored on the provider. Cline checks this inventory before attempting to answer complex architecture questions. Outdated specs get purged automatically. The agent triggers `ai21_delete_file` when you tell it a project phase is complete, ensuring old requirements never pollute your future prompts.
