Exposes OCI (Open Container Initiative) registry operations through the Model Context Protocol (MCP) using Server-Sent Events (SSE) transport. Implements a standardized tool interface that allows LLM applications to query container image metadata (manifests, config, layers) by translating MCP tool calls into authenticated OCI registry API requests, handling content negotiation for different manifest formats (Docker v2, OCI Image Spec).
Unique: Implements MCP as a standardized bridge to OCI registries, enabling any MCP-compatible LLM client to query container images without registry-specific SDKs; uses SSE transport for streaming registry responses directly into LLM context
vs alternatives: Provides registry access through a protocol-agnostic MCP interface rather than requiring LLMs to call registry APIs directly or use language-specific SDKs, reducing integration complexity for multi-registry environments
Implements tag listing functionality that queries OCI registry tag endpoints and returns available image versions for a given repository. Handles pagination for registries with large tag counts and supports filtering/sorting by tag name, creation date, or digest. Works with registry-specific tag listing APIs (Docker Registry V2 _catalog endpoint, Quay API, ECR DescribeImages) abstracted behind a unified MCP tool interface.
Unique: Abstracts registry-specific tag listing APIs (Docker V2 _catalog, Quay API, ECR DescribeImages) into a single MCP tool, handling pagination and format normalization transparently so LLM clients don't need registry-specific logic
vs alternatives: Unified tag enumeration across heterogeneous registries (Docker Hub, ECR, GCR, private registries) through a single MCP interface, whereas direct registry API calls require conditional logic for each registry type
Retrieves and parses container image manifests (Docker Image Manifest V2 or OCI Image Manifest) and associated layer information by negotiating content types with the registry. Handles manifest list resolution (multi-arch images) to select the appropriate platform-specific manifest, extracts layer digests and sizes, and provides access to image configuration blobs. Implements proper HTTP Accept header negotiation to request specific manifest formats from registries.
Unique: Implements full content negotiation for manifest formats (Docker V2, OCI Image Manifest) with automatic manifest list resolution for multi-arch images, exposing platform-specific layer metadata through a single unified MCP tool
vs alternatives: Handles manifest list resolution and platform selection automatically, whereas direct registry API calls require manual Accept header management and conditional logic to select correct manifest variant
Manages authentication to OCI registries through MCP server configuration, supporting multiple credential types (basic auth, OAuth tokens, service accounts) and registry-specific authentication schemes. Implements token caching and refresh logic to minimize authentication overhead for repeated registry requests. Credentials are configured at MCP server startup and transparently applied to all registry API calls without exposing them to the LLM client.
Unique: Centralizes registry authentication at the MCP server level, preventing credentials from being exposed to LLM clients or appearing in model context; implements token caching to reduce authentication overhead for repeated requests
vs alternatives: Isolates registry credentials from LLM context by handling authentication server-side, whereas direct API calls from LLM clients would require embedding credentials in prompts or tool parameters
Generates standardized MCP tool schemas that expose OCI registry operations as callable tools for LLM applications. Implements the MCP tool definition format (JSON schema for inputs, description, name) and registers tools with the MCP server's tool registry. Handles tool invocation routing, parameter validation against schemas, and error handling for invalid tool calls. Supports dynamic tool discovery so LLM clients can query available registry operations.
Unique: Implements full MCP tool lifecycle (schema generation, registration, invocation routing, parameter validation) for OCI registry operations, enabling seamless integration with any MCP-compatible LLM client without custom tool adapters
vs alternatives: Provides standardized MCP tool schemas that work with any MCP client (Claude, custom agents) without client-specific adapters, whereas direct API integration would require building separate tool interfaces for each LLM platform
Implements Server-Sent Events (SSE) as the transport mechanism for MCP protocol communication, allowing the registry MCP server to stream responses back to LLM clients over HTTP. Handles SSE connection lifecycle (connection establishment, keep-alive, graceful closure), message framing, and error propagation through SSE event streams. Enables real-time streaming of large registry responses (manifest lists, tag enumerations) without buffering entire responses in memory.
Unique: Uses SSE as the primary MCP transport mechanism, enabling streaming of large registry responses and persistent connections for sequential queries, whereas typical MCP implementations use JSON-RPC over stdio or WebSocket
vs alternatives: SSE transport provides simpler deployment than WebSocket (no special server configuration needed) while enabling streaming responses, though with lower concurrency than HTTP/2 multiplexing
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 ocireg at 24/100.

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
