cap application context exposure via mcp protocol
Exposes SAP CAP (Cloud Application Programming) project structure, metadata, and configuration as MCP resources through a standardized protocol interface. The server introspects CAP project files (package.json, cds files, data models) and surfaces them as queryable resources that AI clients can discover and reference, enabling context-aware assistance without requiring the AI to parse project structure directly.
Unique: Purpose-built MCP server specifically for SAP CAP projects, introspecting CDS data models and service definitions to expose them as first-class MCP resources rather than generic file access
vs alternatives: Provides CAP-native context exposure through MCP (vs. generic file-based context or manual prompt engineering), enabling AI tools to understand domain-specific patterns like entity relationships and service boundaries
cds entity and service schema introspection
Parses and analyzes CAP's Core Data Services (CDS) definition files to extract entity schemas, relationships, service definitions, and annotations. The server reads .cds files, builds an in-memory representation of the data model, and exposes entity properties, types, associations, and service operations as queryable metadata that AI assistants can use to generate type-safe code.
Unique: Implements CDS-specific parsing logic that understands CAP's domain language (entities, services, associations, annotations) rather than treating CDS as generic text, enabling semantic understanding of data model intent
vs alternatives: Extracts structured schema information from CDS files (vs. passing raw CDS text to AI), allowing AI to generate code that respects type safety and relationship constraints without manual interpretation
mcp resource discovery and listing
Implements the MCP resource listing protocol, allowing clients to discover available resources (CDS entities, services, configuration files) without prior knowledge of the project structure. The server maintains a resource registry that maps CAP project artifacts to MCP resource URIs and provides metadata (name, description, MIME type) for each resource, enabling clients to browse and select relevant context.
Unique: Implements MCP resource listing specifically for CAP artifacts, mapping CDS entities, services, and configuration files to discoverable MCP resources with semantic metadata
vs alternatives: Provides structured resource discovery through MCP (vs. requiring clients to parse project files directly), enabling AI clients to understand available context without project-specific knowledge
mcp resource content retrieval with caching
Handles MCP readResource requests by retrieving and serving CAP project file contents (CDS definitions, configuration, documentation) through the MCP protocol. The server reads files from disk, applies optional caching to reduce I/O for frequently accessed resources, and returns content in appropriate formats (text, JSON) with metadata about the resource type and encoding.
Unique: Implements MCP readResource with optional caching layer for CAP project files, balancing freshness with performance for frequently accessed resources like entity definitions
vs alternatives: Serves project content through MCP protocol (vs. requiring clients to implement file system access), enabling seamless content injection into AI context without manual file handling
tool calling interface for cap development tasks
Exposes CAP development operations as MCP tools that AI clients can invoke, such as generating boilerplate code, validating CDS syntax, or scaffolding new services. The server implements tool definitions with input schemas (JSON Schema) that describe parameters, and executes the corresponding CAP operations, returning structured results that the AI can interpret and present to the user.
Unique: Implements MCP tool calling interface specifically for CAP development operations, with JSON Schema validation of inputs and CAP-aware code generation that respects project conventions
vs alternatives: Enables AI to invoke CAP-specific tools through MCP (vs. generic code generation), ensuring generated code follows CAP patterns and integrates with existing project structure
project configuration and metadata exposure
Reads and exposes CAP project configuration from package.json (cds section), .cdsrc.json, and other configuration files as MCP resources. The server parses configuration to extract project settings (database type, build profiles, middleware configuration) and makes this metadata available to AI clients, enabling context-aware suggestions that respect project-specific settings.
Unique: Extracts and exposes CAP-specific configuration (database type, build profiles, middleware) as structured metadata rather than raw config files, enabling AI to make context-aware suggestions
vs alternatives: Provides parsed configuration metadata (vs. requiring AI to read and interpret raw config files), enabling AI to understand project-specific constraints and generate compatible code
multi-client mcp server lifecycle management
Manages the MCP server lifecycle, handling client connections, protocol negotiation, and request routing. The server implements the MCP protocol specification, manages concurrent client connections, handles protocol versioning, and ensures proper cleanup of resources when clients disconnect. Built on Node.js with support for stdio-based transport (standard for local AI clients like Claude Desktop).
Unique: Implements full MCP protocol server lifecycle management for CAP projects, handling client negotiation and request routing through stdio transport with proper resource cleanup
vs alternatives: Provides complete MCP server implementation (vs. requiring developers to build protocol handling from scratch), enabling immediate integration with Claude Desktop and other MCP clients
cap-aware code generation with template support
Generates CAP-compliant code (CDS entities, services, handlers) using templates that respect CAP conventions and patterns. The server maintains a library of code templates for common CAP structures (entity definitions, service implementations, event handlers) and uses these templates to generate boilerplate code that integrates with the existing project structure and follows best practices.
Unique: Implements CAP-specific code generation with built-in templates for entities, services, and handlers that respect CAP conventions and project structure
vs alternatives: Generates CAP-compliant code using domain-specific templates (vs. generic code generation), ensuring generated code integrates seamlessly with existing CAP projects
