Install & configure

Prerequisites

required
Install Nimble
`nimlangserver` requires `nimble >= 0.16.1`. Install Nim/Nimble so the `nimble` command is available.
required
Install compatible nimsuggest
`nimlangserver` requires a `nimsuggest` version that supports `--v3` (Nim devel with PR 19826 or Nim 1.6+ with PR 19892). Ensure `nimsuggest` is installed and available on PATH.

Install in your client

Paste into the AI you're chatting with — it will figure out the rest

Please install the `nimlangserver` MCP server into my current AI client (that's you).

Required prerequisites (do these first if not already done):
- **Install Nimble** — `nimlangserver` requires `nimble >= 0.16.1`. Install Nim/Nimble so the `nimble` command is available.
- **Install compatible nimsuggest** — `nimlangserver` requires a `nimsuggest` version that supports `--v3` (Nim devel with PR 19826 or Nim 1.6+ with PR 19892). Ensure `nimsuggest` is installed and available on PATH. (https://github.com/nim-lang/Nim/pull/19892)
- **Install nimlangserver** — Install the latest release binary into your Nimble bin directory. Run: `nimble install -g nimlangserver`

Canonical MCP server config (stdio transport):
- command: `nimlangserver`
- args: ["--mcp","--stdio"]

Note: `nimlangserver` defaults to LSP mode, so MCP mode must be selected explicitly with `--mcp`. The README states stdio is the default transport and also mentions socket transport, but it does not provide a canonical MCP client config for socket/http; use stdio for MCP client configuration. No MCP-specific environment variables are documented.

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.
