Install in your client
Paste into the AI you're chatting with — it will figure out the rest
Please install the `dejared` MCP server into my current AI client (that's you).
Required prerequisites (do these first if not already done):
- **Install Node.js 18+** — Required to run npx. (https://nodejs.org)
- **Install Java 17+** — JRE is sufficient; required for the dejared JAR to run. (https://adoptium.net)
Canonical MCP server config (stdio transport):
- command: `npx`
- args: ["-y","dejared-mcp"]
- optional environment variables:
- `DEJARED_JAVA_PATH`: Absolute path to the Java executable, used when Java is not on PATH. (example: `<your-java-path>`)
Note: MCP server for exploring, analyzing, and decompiling Java JAR files using CFR/Vineflower/Procyon.
Add this MCP server to my current client's config in the correct format for you. If you need secrets or credentials I haven't provided, ASK me — do not invent values or leave raw placeholders. After adding it, tell me how to verify the server is connected.Note: MCP server for exploring, analyzing, and decompiling Java JAR files using CFR/Vineflower/Procyon.
