How do I install Cloudflare?

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 Cloudflare need an API key?

No required environment variable is listed on this record.

What transport does Cloudflare use?

Cloudflare runs locally over stdio.

When was Cloudflare last checked?

Questions

Cloudflare MCP Server

An MCP (Model Context Protocol) server that exposes the entire Cloudflare API as tools. Dynamically generates one MCP tool per API operation from the bundled Cloudflare OpenAPI spec — 2,655 operations across 1,686 endpoints covering every Cloudflare service.

How it works

Bundled Cloudflare OpenAPI spec (8.4 MB, 1,686 paths)
  → parse & resolve $refs (swagger-parser)
  → filter operations (optional tag/path/method filters)
  → for each operation:
      → derive tool name from operationId
      → merge path/query params + request body into a single JSON Schema
      → map HTTP method to MCP tool annotations (readOnly, destructive, idempotent)
      → register as an MCP tool with a call handler that calls the Cloudflare API
  → start MCP server over stdio

Features

Entire Cloudflare API — 2,655 operations across 436 service categories (Zones, DNS, Workers, R2, Pages, WAF, Load Balancing, Tunnels, and more)
Dynamic tool generation — tools are generated at startup from the bundled OpenAPI 3.0.3 spec
MCP tool annotations — readOnlyHint, destructiveHint, idempotentHint set automatically based on HTTP method
Tag filtering — --include-tags / --exclude-tags to expose only the API categories you need
Path filtering — --include-paths / --exclude-paths with glob patterns
Method filtering — --include-methods / --exclude-methods to restrict HTTP methods
Security hardening — response sanitization with cryptographic boundary markers (prompt injection defense), response truncation, rate limiting
Bearer token auth — reads CLOUDFLARE_API_TOKEN environment variable

Prerequisites

Java 21 or later
Cloudflare API token — create one here

Quick start

1. Build

git clone https://github.com/wrxck/cloudflare-mcp.git
cd cloudflare-mcp
mvn clean package -DskipTests

This produces target/cloudflare-mcp-1.0.0.jar — a self-contained executable JAR (18 MB).

2. Set your API token

export CLOUDFLARE_API_TOKEN='your-token-here'

3. Register with Claude Code

java -jar target/cloudflare-mcp-1.0.0.jar --install

Or manually:

claude mcp add --scope user --transport stdio cloudflare -- \
  java -jar /path/to/cloudflare-mcp-1.0.0.jar

4. Use

> List my Cloudflare zones
> Show DNS records for example.com
> Create an A record pointing app.example.com to 1.2.3.4
> List my Workers scripts
> What firewall rules are configured on my zone?

Filtering

The full Cloudflare API has 2,655 operations. Use filters to expose only what you need:

By tag (API category)

# Only DNS and Zone tools
java -jar cloudflare-mcp.jar --include-tags "DNS Records,Zones"

# Everything except deprecated APIs
java -jar cloudflare-mcp.jar --exclude-tags "Access Bookmark applications (Deprecated)"

By path

# Only zone-related endpoints
java -jar cloudflare-mcp.jar --include-paths "/zones/**"

# Zone and DNS endpoints
java -jar cloudflare-mcp.jar --include-paths "/zones/**" --include-tags "DNS Records,Zones"

By HTTP method

# Read-only mode — only GET endpoints
java -jar cloudflare-mcp.jar --include-methods "GET"

# No deletes
java -jar cloudflare-mcp.jar --exclude-methods "DELETE"

Common filter presets

Use case	Flags
DNS management	`--include-tags "DNS Records,Zones"`
Workers development	`--include-tags "Worker Script,Workers KV Namespace,Workers for Platforms"`
Security audit	`--include-tags "WAF Managed Rules,Firewall Rules,Account Rulesets,Zone Rulesets"`
Read-only browsing	`--include-methods "GET"`
Storage (R2/KV/D1)	`--include-tags "R2 Bucket,Workers KV Namespace,D1 Database"`

Configuration

Flag	Description	Default
`--install`	Register with Claude Code
`--claude-binary`	Custom Claude binary path	`claude`
`--include-tags`	Comma-separated tags to include	(all)
`--exclude-tags`	Comma-separated tags to exclude	(none)
`--include-paths`	Comma-separated path globs to include	(all)
`--exclude-paths`	Comma-separated path globs to exclude	(none)
`--include-methods`	Comma-separated HTTP methods to include	(all)
`--exclude-methods`	Comma-separated HTTP methods to exclude	(none)
`--max-requests-per-minute`	Rate limit	`240`
`--max-response-length`	Truncate responses beyond this length	`50000`
`--connect-timeout`	Connection timeout in seconds	`10`
`--request-timeout`	Request timeout in seconds	`30`
`--transport`	`stdio` (one client) or `http` (one shared server for many clients)	`stdio`
`--bind`	Address for `http`	`127.0.0.1`
`--port`	Port for `http`	`7401`
`--auth-token-file`	File with the bearer token; required for `http`

Shared HTTP server

By default each Claude session starts its own copy of the server, about 450 MB each. With --transport http, one copy serves every session over MCP streamable HTTP at /mcp.

java -Xmx384m -XX:+UseSerialGC -jar target/cloudflare-mcp-1.1.0.jar \
  --transport http --port 7401 --auth-token-file /run/credentials/mcp-cloudflare.service/token

Every request must send Authorization: Bearer <token>. The server refuses to start if the token file is readable by every user, or if the token has fewer than 32 characters. Register it in Claude Code with a headersHelper that prints the header:

"cloudflare-mcp": {
  "type": "http",
  "url": "http://127.0.0.1:7401/mcp",
  "headersHelper": "/usr/local/bin/mcp-auth-header cloudflare-mcp"
}

Environment variables

Variable	Description	Required
`CLOUDFLARE_API_TOKEN`	Cloudflare API token (Bearer auth)	Yes

Tool annotations

Every generated tool includes MCP annotations based on the HTTP method:

HTTP Method	readOnlyHint	destructiveHint	idempotentHint
GET, HEAD, OPTIONS	true	false	true
POST	false	false	false
PUT	false	false	true
PATCH	false	false	false
DELETE	false	true	true

This means Claude will treat DELETE operations with appropriate caution and won't hesitate to call GET endpoints for information gathering.

Security

Response sanitization — All API responses are wrapped in unique cryptographic boundary markers with instructions to treat the content as untrusted data. This defends against prompt injection via API responses.
Response truncation — Responses are truncated at a configurable limit (default 50k chars) to prevent context overflow.
Rate limiting — Sliding window rate limiter (default 240/minute, matching Cloudflare's 1,200/5-minute limit).
Timeouts — Configurable connect timeout (10s) and request timeout (30s) prevent hanging connections.
Input validation — Required parameters are validated before API calls.
HTTP auth — In http mode, every request needs the bearer token. The compare is constant-time. Bind to 127.0.0.1 only; containers on the host network can reach loopback, and the token is what keeps them out.
