Make CoPilot An Interactive Programmer MCP Server

VS Code AI Agent Interactive Programming. Tools for CoPIlot and other assistants. Can also be used as an MCP server. Exposed over MCP by the make copilot an interactive programmer mcp server, that capability becomes something an assistant can invoke while it works, not something you go and do afterwards.

What it actually does

Clojure Tools for VS Code Agent harnesses. (Such as Copilot and Cursor.)

• Tool: Evaluate Code Access to the Clojure REPL to evaluate code at will. All active REPL sessions in Calva are available for targeting (and with shadow-cljs, also builds and runtime)
• Tool: Create Clojure File Creates Clojure files with automatic bracket balancing
• Tool: Append Code Appends code to Clojure files with automatic bracket balancing
• Tool: Replace Top Level Form Structural editing, including formatting, bracket balancing and linting
• Tool: Insert Top Level Form Structural editing, including formatting, bracket balancing and linting
• Tool: Bracket Balancer Helps the model get the bracket balance right (powered by Parinfer)

Its toolset

Everything the assistant can do here goes through one of these:

• Tool — Evaluate Code Access to the Clojure REPL to evaluate code at will. All active REPL sessions in Calva are available for targeting (and with
• Resource — Symbol info lookup, (a bit experimental) same as the tool
• calva-backseat — driver.evaluation.maxLength (default 25) — maximum number of items to display in collections. Use 0 to disable length limiting
• Skills — The Skills tool exposed by this server
• Prerequisites — The Prerequisites tool exposed by this server
• Using — 0. Teach the AI Clojure and REPL discipline, e.g. See: Agent Instructions 1. Connect Calva to your

Adding it to your client

Setup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client.

Configuration

• VS Code (or your favorite fork) - Calva - Calva Backseat Driver - GitHub Copilot (or some MCP compliant assistant)

When to reach for it

Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Make CoPilot An Interactive Programmer's toolset — Tool, Resource, calva-backseat and 3 more — is a fair guide to whether it matches your workflow. It is maintained by PEZ; worth a glance at recent repository activity before you build anything load-bearing on it.

Caveats

• It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
• MCP clients confirm each tool call by default. Leave that on until you have watched what the make copilot an interactive programmer mcp server does with a few real requests.
