Bootstraps a Model Context Protocol server instance using Svelte as the frontend framework, handling the bidirectional communication channel between MCP clients and the server runtime. The server exposes a standardized MCP interface while delegating UI rendering to Svelte components, enabling reactive, component-based server interfaces without manual protocol message marshaling.
Unique: Demonstrates native Svelte integration with MCP server lifecycle, showing how to bind reactive Svelte stores to MCP resource state changes and tool invocations without middleware abstractions
vs alternatives: Provides a minimal, framework-native example compared to generic MCP server templates, making Svelte-specific patterns explicit rather than requiring developers to infer integration points
Exposes MCP resources (tools, prompts, resources) as Svelte-reactive components, automatically synchronizing resource state with component reactivity. The server maps MCP resource definitions to Svelte stores and component props, enabling UI components to directly reflect and trigger resource state changes without manual subscription management or event listener boilerplate.
Unique: Uses Svelte's reactive declaration syntax ($:) to automatically derive component state from MCP resource changes, eliminating manual subscription boilerplate and enabling declarative resource-UI synchronization
vs alternatives: More concise than imperative event-listener patterns used in vanilla MCP server examples, reducing UI glue code by leveraging Svelte's built-in reactivity system
Handles MCP tool invocations by binding tool parameters to Svelte form components with automatic validation and serialization. When a tool is invoked, the server routes the request through Svelte form handlers that validate inputs against the tool's JSON Schema, execute the tool logic, and return results back through the MCP protocol while updating component state to reflect execution status.
Unique: Leverages Svelte's two-way binding (bind: directive) to create zero-boilerplate form-to-tool mappings, where form input changes automatically update tool parameters and form submission directly triggers MCP tool invocation
vs alternatives: Simpler than React-based MCP server examples that require useState hooks and onChange handlers for each form field; Svelte's bind: syntax reduces form glue code by ~60%
Renders MCP prompt templates as Svelte components, enabling dynamic prompt composition with reactive variable substitution. Prompts defined in the MCP server are mapped to Svelte component templates where variables are bound to reactive stores, allowing prompts to update in real-time as underlying data changes without re-rendering the entire component tree.
Unique: Uses Svelte's reactive declarations ($:) to automatically re-render prompt templates when input variables change, enabling live prompt preview without explicit change detection or memoization
vs alternatives: More reactive than static prompt template systems; changes to variables immediately reflect in the rendered prompt, unlike string-based template engines that require manual re-rendering
Establishes bidirectional communication between MCP clients and the Svelte server using JSON-RPC message passing, with Svelte event handlers managing incoming requests and dispatching responses. The server listens for MCP protocol messages, routes them through Svelte component event handlers (on: directives), and sends responses back to clients while maintaining connection state in Svelte stores.
Unique: Integrates MCP JSON-RPC message handling directly into Svelte's event dispatch system, allowing component event handlers (on: directives) to process MCP requests and trigger responses without separate message routing middleware
vs alternatives: More declarative than imperative message listener patterns; Svelte's on: syntax makes request-response mappings explicit in component templates rather than hidden in event listener registrations
Provides a development server that watches for changes to both MCP server code and Svelte components, automatically reloading the server and re-rendering components without full page refresh. Uses Svelte's HMR (Hot Module Replacement) infrastructure to preserve component state during development while reloading MCP protocol handlers, enabling rapid iteration on both server logic and UI.
Unique: Combines Svelte's HMR infrastructure with MCP server reloading, allowing developers to modify both UI components and protocol handlers in the same edit-reload cycle without manual server restarts
vs alternatives: Faster development iteration than traditional MCP server examples that require manual server restarts; HMR preserves UI state across reloads, reducing context switching during development
Provides a reference project structure demonstrating best practices for organizing MCP server code, Svelte components, and configuration files. The boilerplate includes example tool implementations, sample prompts, resource definitions, and Svelte component templates, enabling developers to understand the expected layout and quickly scaffold new MCP + Svelte projects by copying and modifying the example structure.
Unique: Provides a complete working example of MCP + Svelte integration rather than just documentation, allowing developers to run, inspect, and modify actual code to understand architectural patterns
vs alternatives: More concrete than generic MCP server documentation; developers can immediately see how tools, prompts, and Svelte components interact in a working system rather than reading abstract specifications
Executes SQL queries against Supabase PostgreSQL instances through the Model Context Protocol, translating natural language or structured query requests into parameterized SQL statements. Uses MCP's tool-calling interface to expose database operations as callable functions with schema validation, enabling LLM agents to perform CRUD operations, joins, and aggregations with automatic connection pooling and credential management through Supabase client SDK.
Unique: Exposes Supabase PostgreSQL as MCP tools with automatic credential injection from Supabase client SDK, eliminating manual connection string management and enabling seamless LLM-to-database queries within Claude or compatible agents
vs alternatives: Tighter integration than generic SQL MCP servers because it leverages Supabase's built-in authentication and connection pooling rather than requiring separate database credential configuration
Exposes Supabase Auth session state and user metadata through MCP tools, allowing agents to inspect current authentication context, retrieve user profiles, and trigger auth-related operations. Integrates with Supabase's JWT-based auth system to validate sessions and access user claims without re-authenticating, using the Supabase client's built-in session management.
Unique: Integrates Supabase's JWT-based auth system directly into MCP tool interface, allowing agents to inspect and act on auth state without managing separate credential stores or re-authentication flows
vs alternatives: More seamless than generic auth MCP servers because it leverages Supabase's built-in session management and avoids redundant credential passing between agent and auth system
Invokes Supabase Edge Functions (serverless TypeScript/JavaScript functions) through MCP tools, passing parameters and receiving results with optional streaming support. Uses Supabase's edge function HTTP API to trigger functions with automatic authentication headers and response parsing, enabling agents to execute custom business logic without embedding it in the agent itself.
Supabase scores higher at 42/100 vs @modelcontextprotocol/server-basic-svelte at 21/100.

Unique: Exposes Supabase Edge Functions as MCP tools with automatic authentication and response parsing, allowing agents to invoke custom serverless logic without managing HTTP clients or credential injection
vs alternatives: More integrated than generic HTTP MCP tools because it handles Supabase-specific authentication, error handling, and response formatting automatically
Subscribes to real-time changes on Supabase tables through MCP's event streaming interface, using Supabase's PostgreSQL LISTEN/NOTIFY mechanism to push INSERT, UPDATE, and DELETE events to agents. Maintains persistent WebSocket connections and filters events by table and row-level policies, enabling agents to react to database changes without polling.
Unique: Bridges Supabase's PostgreSQL LISTEN/NOTIFY real-time system with MCP's tool interface, enabling agents to subscribe to database changes without managing WebSocket connections or event serialization
vs alternatives: More efficient than polling-based approaches because it uses Supabase's native real-time infrastructure rather than repeated database queries
Manages files in Supabase Storage buckets through MCP tools, supporting upload, download, list, and delete operations with automatic authentication and path-based access control. Uses Supabase's S3-compatible storage API with built-in support for public/private buckets and signed URLs for temporary access, enabling agents to handle file I/O without managing cloud storage credentials.
Unique: Exposes Supabase Storage's S3-compatible API as MCP tools with automatic authentication and signed URL generation, eliminating the need for agents to manage cloud storage credentials or generate temporary access tokens
vs alternatives: More integrated than generic S3 MCP tools because it leverages Supabase's built-in bucket policies and authentication rather than requiring separate AWS credentials
Performs semantic similarity searches on vector embeddings stored in Supabase PostgreSQL using pgvector extension, translating natural language queries into embedding vectors and executing cosine/L2 distance searches. Integrates with embedding providers (OpenAI, Cohere) or uses pre-computed embeddings, enabling agents to retrieve semantically similar documents or records without full-text search limitations.
Unique: Integrates pgvector directly into MCP tools with automatic embedding generation and distance calculation, enabling agents to perform semantic search without managing separate vector database infrastructure
vs alternatives: More efficient than external vector databases (Pinecone, Weaviate) for Supabase users because it colocates embeddings with relational data, reducing network latency and simplifying data synchronization
Exposes Supabase database schema information through MCP tools, allowing agents to discover table structures, column types, constraints, and relationships without manual schema documentation. Queries PostgreSQL information_schema and Supabase metadata tables to dynamically generate schema descriptions, enabling agents to construct valid queries and understand data relationships.
Unique: Queries Supabase's PostgreSQL information_schema directly through MCP tools, enabling agents to dynamically discover and adapt to database schemas without pre-configured schema definitions
vs alternatives: More flexible than static schema definitions because it reflects live database state, including recent migrations or schema changes
Enforces Supabase Row-Level Security policies within agent queries, ensuring that agents can only access rows permitted by RLS rules defined in the database. Evaluates policies based on authenticated user context (JWT claims, user ID) and applies WHERE clause filters automatically, preventing unauthorized data access at the database layer rather than application layer.
Unique: Delegates authorization enforcement to PostgreSQL RLS policies rather than implementing authorization in agent code, ensuring that data access rules are centralized and cannot be bypassed by agent logic
vs alternatives: More secure than application-level authorization because RLS is enforced at the database layer, preventing accidental data leaks even if agent code has bugs
