Cloudflare

Enables programmatic deployment, updating, and deletion of Cloudflare Workers serverless functions through MCP protocol bindings. Implements a schema-based tool registry that maps Workers API endpoints to structured function calls, allowing Claude or other MCP clients to manage worker versions, routes, and metadata without direct API calls. Handles authentication via Cloudflare API tokens and manages request/response serialization for the Workers REST API.

Provides structured MCP tools for interacting with Cloudflare KV namespaces, supporting get, put, delete, and list operations with TTL and metadata support. Implements namespace isolation through MCP tool parameters, allowing safe multi-tenant access patterns. Handles serialization of arbitrary JSON values and binary data encoding for storage in KV's string-based backend.

Exposes R2 bucket operations through MCP tools including object upload, download, delete, and listing with support for multipart uploads and metadata tagging. Implements streaming for large files to avoid memory exhaustion, with progress tracking via MCP protocol. Handles S3-compatible API calls under the hood while presenting a simplified interface for common storage patterns.

Provides MCP tools for executing SQL queries against D1 databases, including DDL operations (CREATE, ALTER, DROP) and DML operations (SELECT, INSERT, UPDATE, DELETE). Implements parameterized query support to prevent SQL injection, with result streaming for large datasets. Handles connection pooling and transaction management transparently, exposing a simple query interface without explicit connection handling.

Enables deployment of static sites and full-stack applications to Cloudflare Pages through MCP tools, supporting git integration, build configuration, and environment variable management. Implements a declarative approach where deployment state is expressed as structured tool calls, with automatic handling of build triggers and deployment status polling. Supports both direct file uploads and git-based deployments with branch preview environments.

Provides MCP tools for creating, updating, and deleting DNS records (A, AAAA, CNAME, MX, TXT, etc.) within Cloudflare-managed zones. Implements zone-level isolation to prevent cross-zone modifications, with support for DNS routing policies and traffic management. Handles DNS propagation timing and TTL management, allowing Claude to reason about DNS changes and their impact on traffic routing.

Exposes Cloudflare's Web Application Firewall (WAF) and Firewall Rules through MCP tools, enabling creation and modification of security policies including rate limiting, bot management, and custom rule expressions. Implements a rule builder pattern where complex filter expressions are constructed from structured parameters, with validation against Cloudflare's rule syntax. Supports both legacy Firewall Rules and newer WAF Managed Rules with automatic migration guidance.

Provides MCP tools for querying Cloudflare's analytics APIs and Logpush data, supporting time-range filtering, metric aggregation, and log sampling. Implements a query builder pattern where analytics dimensions and metrics are selected through structured parameters, with automatic handling of pagination for large result sets. Supports both real-time analytics (GraphQL API) and historical logs (Logpush), with configurable sampling rates for cost optimization.

Exposes credential management through MCP tools for creating, rotating, and revoking API tokens with fine-grained permission scoping. Implements a permission model where token capabilities are declared upfront (e.g., 'Workers:write', 'KV:read'), with automatic validation against available scopes. Handles token lifecycle management including expiration policies and audit logging, allowing Claude to manage credentials safely without exposing raw tokens.
