How do I install Renovate?

Copy the stdio config for Cursor, Claude Desktop, Claude Code, or VS Code on this page. It uses the publisher's install, not a PlugMCP proxy.

Does Renovate need an API key?

No required environment variable is listed on this record.

What transport does Renovate use?

Renovate runs locally over stdio.

When was Renovate last checked?

Server MCP Renovate

renovate-mcp

An MCP server for designing Renovate configurations interactively. Point it at a local repo and let an LLM help you read, validate, preview, and save renovate.json.

Quick start

Needs Node.js ≥ 24.11 on Linux or macOS. With Claude Code:

npm install -g renovate-mcp
claude mcp add renovate -s user -- renovate-mcp
claude mcp list   # renovate should show as connected

Then try the prompt: "List the namespaces available under renovate://presets." A response listing config, docker, npm, … confirms the server is reachable. No tokens are needed for the offline tools. Other clients, tokens and upgrades are under Install below.

What you can do

Read and explain configs — locate the active renovate.json*, expand every extends preset offline, and trace which preset set each field.
Discover presets from intent — describe what you want ("automerge patches, group dev deps") and get ranked built-in (and your own local-repo) presets, plus a draft config skeleton when nothing fits.
Preview custom managers before running Renovate — regex and JSONata, with Renovate's managerFilePatterns glob/regex file selection, file/line hits and extracted dep info.
Validate and lint — schema validation plus a semantic lint pass for Renovate-specific footguns (unwrapped regexes, unknown manager names, deprecated keys).
Dry-run against a local checkout or a remote GitHub/GitLab — see exactly which PRs Renovate would open.
Save back atomically — round-trip writes preserve comments and key order in existing JSON-with-comments files.

Tools & resources

Eighteen tools, seven resources, and four workflow prompts. Each tool name below links to its full reference in docs/tools.md.

Tool	Purpose
`check_setup`	Report Renovate CLI + validator availability, versions, install hints, and a `platformContext` block for env diagnosis. Also runs at startup. Pass an optional `repoPath` to add a `repoContext` block diagnosing the repo's git origin, config endpoint/platform, endpoint reachability, and token coverage.
`get_version`	Report the renovate-mcp server version and whether it's a released or local/dev build.
`read_config`	Locate and parse a repo's Renovate config in Renovate's own discovery order.
`suggest_presets`	Search built-in (and optional local-repo) presets by natural-language intent; ranks matches and sketches an unvalidated draft config skeleton for multi-facet or weakly-covered intents. Offline.
`resolve_config`	Expand every `extends` preset offline. Opt in to fetching `github>` / `gitlab>` / `gitea>` / `forgejo>` presets over HTTPS, or Bitbucket Cloud presets via `local>` + `platform`.
`explain_config`	Inverse of `resolve_config`: annotate every leaf field with the chain of presets that set it.
`resolve_config_diff`	Offline structural diff of two fully-resolved configs — changed fields plus an order-insensitive set diff of array keys (`packageRules`, `customManagers`, …). The refactor-friendly counterpart to .

Prompts. Four workflow prompts package the tool sequences above into ready-to-run starting points. Claude Code surfaces MCP prompts as slash commands (e.g. /mcp__renovate__design-renovate-config); other MCP clients expose them through their own prompt picker.

Prompt	Drives
`design-renovate-config`	`check_setup` → `read_config` → `suggest_presets` → `resolve_config`/`explain_config` → `validate_config`/`lint_config` → `dry_run` → `write_config` on confirmation.
`debug-package-rule`	`check_setup` → `read_config` → `test_package_rules` (matches + rendered names) → `dry_run` (with `reportOutputPath`) → `annotate_dry_run` → `explain_dependency` → a verdict naming rule indices and matchers.
`author-custom-manager`	Draft a `customManagers` entry → `preview_custom_manager` iteratively → `validate_config`/`lint_config` → `dry_run` → `write_config` on confirmation.
`onboard-repo`	For repos without a config: `check_setup` → `read_config` (expect none) → `dry_run` (extract mode) → `suggest_presets` → `lint_config`/`validate_config` → `write_config` on confirmation → full `dry_run`.

Requirements

Linux or macOS. Windows is not supported — package.json declares "os": ["darwin", "linux"], so npm i surfaces an EBADPLATFORM warning on Windows and the server exits with a clear stderr message at startup. Use WSL2 or a Linux/macOS host instead.
Node.js ≥ 24.11 (aligns with Renovate's own engine requirement).

Renovate ships bundled — the renovate package is a runtime dependency, so validate_config, dry_run, and write_config work out of the box with no separate install. The offline tools (read_config, suggest_presets, resolve_config, explain_config, resolve_config_diff, test_package_rules, preview_custom_manager, lint_config, dry_run_diff, annotate_dry_run, explain_dependency, migrate_config) never spawn Renovate at all — nor do check_setup (by default it reads version metadata from the bundled install instead of spawning) or get_version (it only reports the renovate-mcp server's own version).

Optional env vars:

RENOVATE_BIN / RENOVATE_CONFIG_VALIDATOR_BIN — override the bundled binaries. When set, the override always wins.
RENOVATE_MCP_REQUIRE_CLI=false — suppress the startup "partial availability" notice when you only intend to use the offline tools.
Platform + token env vars — see docs/platform-setup.md for the per-platform matrix.
GITHUB_COM_TOKEN — authenticates github.com datasource lookups (release notes, github-tags / github-releases / github-actions). Distinct from the platform token and never auto-derived from it; set it when github.com-hosted deps are resolved under the default dry_run platform: local. See docs/security.md.

Heads up: MCP servers do not inherit your shell env. Set every env var via the env key in .mcp.json / claude_desktop_config.json. See docs/security.md.

Install

1. Install the package

npm install -g renovate-mcp

Install before you register the server. The package bundles Renovate (about 670 packages, 350 MB), so a client that starts npx -y renovate-mcp against a cold npm cache downloads all of that during server startup and can time out.

Upgrade with npm install -g renovate-mcp@latest and restart your client. With nvm or fnm, global packages belong to one Node version — reinstall after switching.

2. Register it with your client

Claude Code:

claude mcp add renovate -s user -- renovate-mcp

-s user makes the server available in every project. Leave it out to register it for the current project only, or use -s project to write a shared .mcp.json.

Claude Desktop and other GUI clients don't load your shell's PATH, so with nvm, fnm or Homebrew they may find no Node or an older one. Use absolute paths:

which node                                        # → "command"
echo "$(npm root -g)/renovate-mcp/dist/index.js"  # → "args"

Claude Desktop reads ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "renovate": {
      "command": "/Users/you/.nvm/versions/node/v24.14.1/bin/node",
      "args": ["/Users/you/.nvm/versions/node/v24.14.1/lib/node_modules/renovate-mcp/dist/index.js"]
    }
  }
}

Any other client that can launch a stdio MCP server works with the same command.

3. Add tokens (optional)

The offline tools need nothing. Add env vars only for what you use:

Use case	Env vars
Local `dry_run` on a repo with github.com dependencies	`GITHUB_COM_TOKEN` (read-only PAT, avoids anonymous rate limits)
`dry_run` against GitHub, or private `github>` presets	`RENOVATE_PLATFORM=github` + `GITHUB_TOKEN`
`dry_run` against GitLab, or private `gitlab>` presets	`RENOVATE_PLATFORM=gitlab` + `GITLAB_TOKEN`

Self-hosted GitLab and GitHub Enterprise also need RENOVATE_ENDPOINT — see Platform setup.

In Claude Code, re-register with -e:

claude mcp remove renovate -s user
claude mcp add renovate -s user -e GITHUB_COM_TOKEN=ghp_xxx -- renovate-mcp

-e stores the value in plain text in ~/.claude.json. Keep tokens in user or local scope, never in a project-scope .mcp.json that gets committed.
-e accepts several values, so keep the -- before renovate-mcp.
Other clients take the same variables in an "env": { … } block next to "args".

Alternatives

npx without a global install — register npx -y renovate-mcp instead, after warming the npm cache once with npm exec --yes --package=renovate-mcp -- node -e 0.
Installer script — curl -fsSL https://raw.githubusercontent.com/tibuntu/renovate-mcp/main/install.sh | bash runs steps 1 and 2 interactively: it checks Node, asks for npx or global mode, verifies the server with an MCP initialize handshake, and registers it via claude mcp add when the Claude Code CLI is on PATH. Flags (after bash -s --): --global, --npx, --no-mcp-add, --mcp-scope=user|project|local, --version=X.Y.Z; also accepted as env vars (RENOVATE_MCP_GLOBAL=1, RENOVATE_MCP_NO_MCP_ADD=1, RENOVATE_MCP_VERSION=…).
From source — clone, run npm install && npm run build, and point your client at node /absolute/path/to/renovate-mcp/dist/index.js.

Platform setup

For dry_run against a remote platform or resolve_config with externalPresets: true:

Setup	`RENOVATE_PLATFORM`	`RENOVATE_ENDPOINT`	Token
github.com	`github`	(omit)	`RENOVATE_TOKEN` or `GITHUB_TOKEN`
GitHub Enterprise	`github`	`https://github.example.com/api/v3/`	`RENOVATE_TOKEN` or `GITHUB_TOKEN`
gitlab.com	`gitlab`	(omit)	`RENOVATE_TOKEN` or `GITLAB_TOKEN`
Self-hosted GitLab	`gitlab`	`https://gitlab.example.com/api/v4/`	`RENOVATE_TOKEN` or `GITLAB_TOKEN`
gitea.com / Forgejo (code.forgejo.org)	—	(omit)	`RENOVATE_TOKEN` or `GITEA_TOKEN` / `FORGEJO_TOKEN`
Self-hosted Gitea / Forgejo	—	`https://forgejo.example.com/api/v1/`	`RENOVATE_TOKEN` or `GITEA_TOKEN` / `FORGEJO_TOKEN`
Bitbucket Cloud	—	(omit)	`RENOVATE_TOKEN` or `BITBUCKET_TOKEN`

The Gitea / Forgejo / Bitbucket Cloud rows apply to the resolve_config family only: dry_run runs Renovate as local / github / gitlab and never reads those tokens. Pass platform (gitea / forgejo / bitbucket) and endpoint as tool inputs instead of RENOVATE_PLATFORM / RENOVATE_ENDPOINT.

See docs/platform-setup.md for a worked self-hosted GitLab example, local> preset handling, and private-registry credentials.

Example prompts

Once the server is wired up, try prompts like these. Written for Claude but work with any MCP-capable client.

Understanding an existing config

"Read the Renovate config in this repo and summarize what it actually does — expand every preset so I can see the real effective behavior."
"Resolve my config and list anything that landed in presetsUnresolved, with the reason for each."
"Why is my prCreation set to not-pending? Use explain_config to trace which preset set it."

Discovering & browsing presets

"I want to automerge patch and minor updates and group my dev dependencies — suggest presets for that, search my ../renovate-presets repo too, and draft a config I can validate."
"List the presets in the config namespace." (uses the renovate://presets/config sub-resource — cheaper than pulling the whole index)
"What does config:recommended actually enable? Show me its expanded JSON."
"Find a built-in preset that pins GitHub Actions digests." (or use suggest_presets with that intent)

Self-hosted GitLab / GitHub Enterprise (env set per Platform setup)

"Resolve my config with external presets enabled, fetching gitlab>platform/renovate-presets from our self-hosted GitLab at https://gitlab.example.com/api/v4. Route local> presets through the same host."
"Expand github>acme/renovate-config//base from our GitHub Enterprise at https://github.acme.corp/api/v3."
"Dry-run infrastructure/kubernetes/our-platform (a nested-group GitLab project) so Renovate can fetch the local> presets the config extends."

Authoring a custom manager (regex or JSONata)

"I have # renovate: datasource=docker depName=... comments above image tags in my Dockerfiles. Draft a customManagers regex entry with managerFilePatterns: ["**/Dockerfile"] and preview it against this repo so I can see what it extracts."
"Here's a customManagers entry — preview it and tell me which files match managerFilePatterns, which lines hit each matchStrings regex, and what dep info gets extracted."
"My custom manager still uses fileMatch. Lint the config, then run migrate_config so it becomes managerFilePatterns."
"Draft a customType: \"jsonata\" customManager with fileFormat: \"yaml\" to extract Helm chart dependencies (name, version, repository) from Chart.yaml, and preview it against this repo."

Validating, previewing, saving

"Validate this proposed config against Renovate's schema without writing it anywhere."
"Do a dry run and show me which PRs Renovate would open — no pushes."
"Why didn't Renovate update lodash? Run a dry run and explain that dependency."
"Add :semanticCommits to my extends, validate it, and save back to renovate.json."

Example session

A transcript-style walkthrough: design a Dockerfile custom manager from scratch, validate it, dry-run, and save. Turns are abbreviated — your client will show the actual tool-call JSON.

You: I've got # renovate: datasource=docker depName=<image> comments above FROM lines in my Dockerfiles. Draft a customManagers entry and preview it against this repo.

Claude calls preview_custom_manager with a first-draft managerFilePatterns (**/Dockerfile) + matchStrings. → 4 Dockerfiles matched managerFilePatterns, 0 lines matched matchStrings. The regex anchored on ARG, but the Dockerfiles use FROM.

You: Rewrite matchStrings to anchor on the renovate comment, then FROM <image>:<version> on the next line.

Claude calls preview_custom_manager again with the fixed regex. → 4 files, 4 line hits. Extracted: postgres:15.3-alpine, redis:7.2, nginx:1.25, node:20.11. Named groups depName and currentValue populated on every hit.

You: Good. Validate the full config inline, with this customManagers entry alongside my existing extends.

Claude calls validate_config with the inline config. → valid.

You: Now dry-run so I can see what Renovate would actually open.

Claude calls dry_run. → 2 updates: postgres 15.3-alpine → 15.5-alpine, redis 7.2 → 7.4. No entries in problems.

You: Save it.

Claude calls write_config on renovate.json. → validated, written atomically; because the file already existed and parsed as JSON-with-comments, the round-trip serializer preserved the surrounding comments and key order — only the customManagers slice was edited in place.

What this is NOT

Not a Renovate replacement. This server doesn't open PRs, run scheduled updates, or execute in CI — it's a design-time companion for a local renovate.json. Use the real Renovate for the actual dependency-update pipeline.
resolve_config merges faithfully. Preset expansion runs offline against a committed snapshot, then folds with Renovate's real mergeChildConfig in a worker thread — mergeQuality: "faithful" (it falls back to an approximate in-process merge as "preview" only if the worker is unavailable). Template substitution still implements only positional {{argN}} placeholders — non-positional tokens and Handlebars helpers are flagged in warnings and pass through verbatim. For full config resolution (datasource lookups, etc.), run dry_run.
preview_custom_manager is a subset of Renovate's custom managers. It covers customType: "regex" (with matchStringsStrategy of any / combination / recursive) and customType: "jsonata" (with fileFormat: "json" | "yaml" | "toml"). File selection follows Renovate's managerFilePatterns semantics (globs or /regex/, entries unioned like Renovate's extract phase); the deprecated fileMatch is still accepted with a warning. Template substitution is {{groupName}} only — full Handlebars helpers/conditionals are not implemented. Other custom types (e.g. html) are out of scope. Use it for fast iteration; confirm with dry_run. Full coverage matrix in docs/tools.md#preview_custom_manager.
dry_run still uses fake binaries in CI. The bundled Renovate is available (it's a runtime dependency), and validate_config / write_config have real-validator integration tests (test/integration/realValidator.test.ts) exercising the actual bundled renovate-config-validator — but dry_run itself still runs per-PR against fake binaries via RENOVATE_BIN / RENOVATE_CONFIG_VALIDATOR_BIN env overrides, for determinism and speed. A separate nightly workflow re-runs the full suite against renovate@latest end-to-end. Run dry_run locally against a real config to validate behaviour.
