MCP server support is available

Why

You can ask your agent (like codex) to do some jobs with your editor, like:

• Fix the issue at current cursor position.
• Use the tool workspace/apply_edit to apply workspace edits (so you can use workspace.undo and workspace.redo command provided by coc.nvim)

Quick start

1. In coc-settings.json (:CocConfig) add whitelist tools (default: none exposed): :

{ "mcp": { "allowedTools": ["editor/state", "document/read", "workspace/apply_edit"] } }

2. The MCP server is not started by default, start your vim and coc.nvim mcp server by vim command:

:CocCommand mcp.start

3. In ~/.codex/config.toml:

[mcp_servers.coc]
command = "node"
#  add "--match-first" if your codex is not started with the same cwd of coc.nvim
args = ["/path/to/coc.nvim/bin/coc-mcp.js"]
enabled = true

4. Start your codex form the same cwd of coc.nvim, and use command /mcp to verify the mcp status.

5. Try tools: editor/state, document/read, workspace/apply_edit.

Checkout :h coc-mcp for coc.nvim mcp details, more useful tools is coming.

Hi @chemzqm , glad you're back and driving the project again — the MCP work looks great. Curious about your vision going forward:

1. Is MCP/AI integration the main direction, or part of a bigger plan?
2. What MCP tools are planned next?

[chemzqm]

Here's the future roadmap for this project:

• Comprehensive auditing and fixes, along with performance improvements — this is largely complete at this point.
• Plugin upgrades in sync with the core, plus integration testing via coc-test to ensure reliability. We're still figuring out the most efficient approach for this.
• Enhanced MCP support — we'll add and refine the provided tools, but since MCP itself is fairly limited and modern LLMs don't heavily rely on those features, this isn't a top priority.
• A brand-new AI integration plugin to deliver a native AI experience in Vim, drawing inspiration from plugins like Continue to offer more useful capabilities — unlike GitHub Copilot, which doesn't provide much in the way of meaningful completions.
• Plugin-based ACP support to directly drive agents. Since ACP is still in its early stages, we'll first research what needs to be added to support it, so this won't be implemented anytime soon.

If you have any feedback or suggestions, feel free to let me know.

A special reminder for users running DeepSeek V4 Flash under Codex: make sure to set "supports_search_tool": false for the DeepSeek model in models.json to make DeepSeek V4 Flash use MCP tools.
