feat(init): set up the Netlify MCP server for the project by domitriusclark · Pull Request #8638 · netlify/cli

domitriusclark · 2026-10-20T01:45:16Z

Summary

netlify init now adds the Netlify MCP server for the project. Claude is installed with claude mcp add --scope local, and every other agent gets a printed add-mcp command, after a check for an existing Netlify server. Project scope matches what init sets up; --mcp-scope user widens it.

When a person runs init in a terminal, they get a checkbox of agents that support the chosen scope. Agents found from the editor terminal or project folders are preticked; other installed agent CLIs are listed unticked.

Claude Code: a tick runs claude mcp add --transport http --scope local netlify https://mcp.netlify.com/mcp. Nothing is written to the repo.
Other agents: a tick prints npx -y add-mcp@2.4.1 https://mcp.netlify.com/mcp --name netlify -y -a <agent> and names the project file it writes.
Windsurf and Cline have no per-project config, so they're left out at project scope and only offered with --mcp-scope user. -g is never printed at project scope.
With --mcp-scope user, Claude and Codex run their own CLIs after the existing-server check. VS Code can't be checked first, so its command is printed with a note that running it replaces an existing netlify entry. The other agents, OpenCode included, get the add-mcp command with -g.
Answers are saved in .netlify/state.json under agentMcpSetup.<scope>.<agent>, as accepted, declined or kept (an existing server left alone). A rerun only asks about new agents, and each scope keeps its own answer. --reset-mcp-setup asks again.

When an agent runs init, an agent init knows (Claude Code, Codex, Cursor and the others in MCP_AGENTS) gets no prompt. Claude is installed at project scope after the existing-server check; if the check fails, nothing is installed. Other agents get the printed command. A saved "no" for that scope is honored, and nothing goes user-wide without --mcp-scope user. With --reset-mcp-setup, the saved "no" is skipped for that run and replaced once the server is added or already there. That's the only time an agent run writes .netlify/state.json; a failed add or a printed command leaves it untouched. An agent init doesn't know gets the checkbox when a terminal is attached; without one, it gets the generic add-mcp command with how to run it without its questions (-y -a <agent>, list-agents).

Existing servers are left alone. Claude is checked with claude mcp list (every scope and plugin servers; servers still pending .mcp.json approval don't count), Codex with codex mcp list --json. With --mcp-scope user, a Claude entry only counts if claude mcp get reports it at user scope, and Codex is checked from the home folder so project config isn't read. The hosted URL is matched exactly. Any netlify or plugin:*:netlify server, a Netlify MCP host, or @netlify/mcp counts as an existing Netlify server, under any name, and is reported instead of duplicated.

Skills and MCP are skipped when init runs from the file system root. From the home directory, skills are skipped, and MCP is too unless --mcp-scope user is passed. Agent CLIs are found only through absolute PATH entries, using isexe.

Tests

npm exec vitest -- run tests/unit/utils/init/: 134 passed, including saving and resetting against a real .netlify/state.json
npm exec vitest -- run tests/integration/commands/init/init.test.ts: 12 passed, using a fake claude on PATH, including init from the home directory (with and without --mcp-scope user) and a saved "no" held until --reset-mcp-setup
typecheck, lint, format:check and docs regeneration are clean
Reviews: fresh full-PR reviews found nothing blocking; Codex adversarial findings are fixed, except running add-mcp from init, which stays a printed command. Each review round's fixes got a fresh review before pushing.

Risk

claude mcp list health-checks every approved server and can take up to 30s.
An agent init knows skips the prompt even with a terminal attached, which Copilot and Cursor need since they run commands in the editor's terminal. A person whose shell sets NETLIFY_AGENT or CLAUDE_CODE_CHILD_SESSION=1 gets Claude configured for the project without being asked.
Saved choices go in the nearest .netlify/state.json, which can be an ancestor folder's in a monorepo.
Windows runs the unit tests, including the relative-PATH ones; the integration tests use a shell-script fake claude and skip there.
At user scope, only the first Netlify entry's scope is checked. With our server set for this project only and another Netlify server user-wide under a different name, a second user-wide Netlify entry gets added. That's rare, so it's left unhandled.

Related: rerunning init on a project linked without git creates a duplicate site today; the fix is #8646.

Rollback: revert this PR. Anyone who already has the entry can remove it with claude mcp remove --scope local netlify, or --scope user if they used --mcp-scope user.

init now runs `claude mcp add --scope local` for the hosted server, so nothing lands in the repo. Agent setup also skips the home directory and folders with no project marker, which stops skills leaking into ~/.claude.

Summary

Summary by CodeRabbit

New Features
- Added MCP server setup options to init, including project or user scope, the ability to skip MCP setup independently, and an option to reset saved setup choices.
- init can configure MCP support for detected AI coding agents and recognize existing server configurations.
- Agent setup avoids writing skills or MCP configuration in home-directory and filesystem-root locations.
Documentation
- Updated the init command documentation with the new options and clarified what --skip-agent-setup skips.

The init command adds options to configure the Netlify MCP server for supported AI agents, select project or user scope, and reset saved setup choices. The change adds agent discovery, server lookup, selection, and choice persistence. Setup checks the project location before installing skills or configuring MCP. Documentation and tests cover the options and setup behavior.

Estimated code review effort: 4 (Complex) | ~60 minutes

Change: Feature

Suggested reviewers: serhalp, sarahetter

Merge Risk: Low · up to 617f2

A reset may leave an absent agent’s choice in place, and setup from a filesystem root that is also home can proceed at user scope. A rare interrupted config write could also damage an agent’s project configuration. These issues warrant owner awareness or fixes before merging.

commit: 617f2e3

Pick the agent running init, or ask a person with a checkbox preticked from their editor terminal and project folders. Claude, Codex, OpenCode and VS Code get the server at user scope through their own CLIs; other agents get a pinned add-mcp command. Regenerate init docs.

Save each prompted yes or no in the global config, keyed by agent and server URL, so reruns only ask about new agents. --reset-mcp-setup asks again. Agent-driven runs are unchanged.

The project-marker check skipped skills in an empty folder, the usual start for an agent building a new site. Block only the home directory and the file system root, and apply that guard to skills, not MCP.

[blocking] An agent-driven run adds the server at user scope with no prompt, and ignores a saved "declined".

Say someone unticks Claude Code in the checkbox, then later Claude Code runs netlify init for them. It gets added anyway. --reset-mcp-setup doesn't reach this branch either. And the header in agent-detection.ts says its result is "never for authorization" — this is the thing deciding whether to write to someone's user config.

[blocking] On Windows this can run a claude.cmd (or codex.cmd, code.cmd) from the project folder instead of the one on PATH.

execa goes through cross-spawn, which resolves the command from cwd, and the Windows lookup checks the current directory before PATH. So a repo with a claude.cmd at the root runs it when someone runs netlify init in their clone, without a prompt if an agent is driving.

[blocking] Does opencode mcp add take a name and --url? The OpenCode CLI docs show it as an interactive wizard with no flags, and the tests mock execa, so nothing here runs the real thing.

[consider] Any existing netlify entry counts as present, whatever URL it points at, and in the checkbox flow that gets saved as accepted, so they're not asked again. Only the legacy host gets a note.

[consider] Every run without the fake claude adds --skip-mcp-setup, so nothing checks that --skip-agent-setup on its own now skips MCP too. --reset-mcp-setup is only tested by calling setupAgentMcp directly, not through the command.

[consider] This is a third list of agents to keep in step, next to AGENT_DIRECTORY_BY_DRIVING_AGENT in agent-skills.ts and the name table in agent-detection.ts, with drivenBy mapping between them by hand.

[nit] shellQuote uses POSIX single quotes, so the printed code --add-mcp '{...}' fallback won't paste into cmd on Windows.

[nit] Other spots check ENOENT with an isErrnoException guard (src/utils/shell.ts:192) rather than a cast.

Agent-driven runs now look up and print the add command instead of writing user config, and honor a saved no and --reset-mcp-setup. Agent binaries resolve from absolute PATH entries only, so a project-local claude.cmd never runs. A server on another URL is reported, not counted as present.

A ticked agent whose netlify server was left unchanged is no longer saved as accepted. Clarify the message for non-hosted entries, note when VS Code or OpenCode may have replaced one, and drop a dead branch.

Default to project scope: Claude via claude mcp add --scope local, other agents via a printed add-mcp project command. --mcp-scope user keeps the user-wide path. Check every scope and plugin for an existing Netlify server first, save choices in .netlify/state.json, skip MCP in ~ and /, and match the hosted URL exactly.

…o run

Agent runs now install at the chosen scope (project by default) after the same existing-server check as a ticked agent. A saved no and --reset-mcp-setup still apply, and nothing goes user-wide without --mcp-scope user.

Agents with no lookup get a printed command instead of a silent replace; project scope never prints -g and reports Windsurf and Cline as unsupported; Codex is checked with mcp list --json across all names; --reset-mcp-setup only deletes an existing saved choice. Tests cover the real .netlify/state.json.

--reset-mcp-setup in an agent run now bypasses a saved no in memory instead of deleting it, so agent runs never write .netlify/state.json.

Fix the Windows PATHEXT casing in tests and make the relative-PATH test able to fail. Key saved choices by scope and remember kept servers. An unmapped agent with a terminal gets the checkbox. Use isexe, and test the home guard and --reset-mcp-setup through the init command.

seancdavis

a couple of blockers and then a bunch of other nits

Check scope before treating a Claude entry as user-wide, skip pending .mcp.json servers, let reset replace or forget saved choices, allow --mcp-scope user from home, and tighten URL matching and printed names.

Follow-up from review: a user-wide server under another name now counts, failure output is printed without control characters, and the skip hint names what was skipped.

Check only the matched entry's scope at user scope, print agent errors as-is, and drop two tests that repeat the in-memory reset checks.

seancdavis

Left notes inline. The description's out of date in a few spots too: agent runs do write state.json on a reset, the home directory with --mcp-scope user doesn't skip MCP, and the relative-PATH tests don't skip on Windows anymore.

seancdavis · 2026-10-27T16:07:19Z

+  if (run.exitCode !== 0) {
+    return { found: 'unknown', run }
+  }
+  const lookup = classify(listedServers(run.stdout))


[consider] Only the first Netlify entry gets its scope checked. A project-local netlify plus a user-wide Netlify server under another name comes back none, and a second user-wide entry gets added. cdde3f9 handled this and 49efae0 took it back out, along with its test.

Leaving this out on purpose. It needs our server set for this project only plus another Netlify server user-wide under a different name, which is rare, and the fix cost an extra claude mcp get per entry. It's listed under Risk in the description. If you've seen it happen, I'll put it back.

Check Codex from the home folder at user scope so project config doesn't count, keep a saved no unless the server is installed, filter agent error output, and check the add's working folder.

seancdavis

one fix left -- see inline comment

Newer opencode mcp add writes project config without --global, and older versions reject --global, so print the add-mcp command instead.

init now uses the detected agent to choose which config to write.

The integration test for --reset-mcp-setup checks only stdout and the fake claude call log. It never reads .netlify/state.json. If the reset run fails to save the accepted choice, the seeded declined entry remains, and the test still passes.

Add an assertion for the saved choice after the reset run:

Check the filesystem root before the home directory.

When the home directory is /, findProjectSetupBlocker returns place: 'home'. setUpAgents then skips the root block, so --mcp-scope user sets up MCP from /. Move the root check above the home check. The reason text also shows the home message at /, so the root check fixes that too.

Forget saved choices for agents that are not detected on an interactive reset.

--reset-mcp-setup must forget the saved choices for the active scope. The interactive reset path only handles detected candidates. A saved accepted, declined, or kept entry for an agent that is not detected stays in .netlify/state.json. When that agent is installed later, the entry hides it from the prompt on a later run.

Clear the entries for agents that are not candidates. This includes the case where no agent is detected. Keep the agent-driven path unchanged. A failed add on that path must not write or delete state.

Suggested fix

At project scope, init now adds the Netlify MCP server to the agent's own config file instead of printing an add-mcp command, which agents and people often skipped. A file is only edited when it can be reproduced byte for byte; Codex's TOML is appended and re-parsed. Anything else falls back to the printed command with the reason.

Write the project config atomically.

fs.writeFile truncates the target before it writes the new content. A crash or a concurrent read during that write can leave a truncated user-owned config file, and the agent that reads it can fail at startup. write-file-atomic is already a runtime dependency. It writes a temporary file in the same directory and renames it over the target. It also resolves symlinks before the rename, so a symlinked config keeps its link.

♻️ Proposed fix

import toml from 'toml' +import writeFileAtomic from 'write-file-atomic'

- await fs.writeFile(target, updated, 'utf8') + await writeFileAtomic(target, updated, 'utf8')

feat(init): add Netlify MCP server for Claude Code

4157f26

init now runs `claude mcp add --scope local` for the hosted server, so nothing lands in the repo. Agent setup also skips the home directory and folders with no project marker, which stops skills leaking into ~/.claude.

feat(init): remember MCP agent choices per user

0d3de81

Save each prompted yes or no in the global config, keyed by agent and server URL, so reruns only ask about new agents. --reset-mcp-setup asks again. Agent-driven runs are unchanged.

test(init): use .cmd fake agent binaries on Windows

fix(init): install skills in new and empty folders

bb3ddc1

The project-marker check skipped skills in an empty folder, the usual start for an agent building a new site. Block only the home directory and the file system root, and apply that guard to skills, not MCP.

fix(init): re-offer agents that kept another MCP server

f6a8241

A ticked agent whose netlify server was left unchanged is no longer saved as accepted. Clarify the message for non-hosted entries, note when VS Code or OpenCode may have replaced one, and drop a dead branch.

feat(init): add the MCP server for the agent running init

404f7ab

Agent runs now install at the chosen scope (project by default) after the same existing-server check as a ticked agent. A saved no and --reset-mcp-setup still apply, and nothing goes user-wide without --mcp-scope user.

fix(init): keep agent runs from touching saved MCP choices

b70b3e3

--reset-mcp-setup in an agent run now bypasses a saved no in memory instead of deleting it, so agent runs never write .netlify/state.json.

fix(init): address MCP setup review round four

5c7d7c4

Check scope before treating a Claude entry as user-wide, skip pending .mcp.json servers, let reset replace or forget saved choices, allow --mcp-scope user from home, and tighten URL matching and printed names.

fix(init): check every Netlify entry at user scope

cdde3f9

Follow-up from review: a user-wide server under another name now counts, failure output is printed without control characters, and the skip hint names what was skipped.
