Query the OSV database to retrieve vulnerability information for a specific package and version combination. The MCP server translates package identifiers (name, version, ecosystem) into OSV API calls, returning structured vulnerability records with severity, affected versions, and remediation guidance. Supports multiple package ecosystems (npm, PyPI, Maven, etc.) through OSV's unified schema.
Unique: Exposes OSV's unified vulnerability schema across heterogeneous package ecosystems through a single MCP interface, abstracting away ecosystem-specific API differences and enabling consistent vulnerability queries regardless of package manager
vs alternatives: Broader ecosystem coverage than Snyk or GitHub Dependabot because it queries the open-source OSV database directly rather than relying on proprietary vulnerability feeds
Query vulnerabilities by Git commit SHA, enabling vulnerability detection at the source code level rather than package level. The MCP server translates commit hashes into OSV API queries, returning vulnerabilities that affect that specific commit in the repository's history. Useful for detecting vulnerabilities in dependencies pinned to specific commits or for analyzing historical code snapshots.
Unique: Enables commit-hash-based vulnerability queries, which is critical for Git-pinned dependencies and source-level security audits — a capability not commonly exposed in package-manager-centric vulnerability tools
vs alternatives: Unique ability to query vulnerabilities at the commit level rather than package version, enabling security analysis of Git-based dependency pinning strategies that bypass traditional package managers
Submit multiple package-version pairs in a single request and receive vulnerability data for all of them in one response. The MCP server batches requests to the OSV API, reducing round-trip latency and enabling efficient scanning of entire dependency manifests (package.json, requirements.txt, pom.xml, etc.). Implements request coalescing to minimize API calls while handling partial failures gracefully.
Unique: Implements batch query aggregation at the MCP layer, allowing clients to submit multiple packages in a single tool call and receive coalesced results, reducing network round-trips and API call overhead compared to sequential queries
vs alternatives: More efficient than making individual API calls for each dependency because batch requests reduce network latency and API overhead, making it practical for scanning large dependency trees in CI/CD pipelines
Fetch comprehensive vulnerability details by OSV ID (e.g., GHSA-xxxx-xxxx-xxxx, CVE-YYYY-NNNNN). The MCP server queries the OSV database for the full vulnerability record, including affected versions, severity scores (CVSS), remediation steps, references, and related advisories. Returns structured data suitable for generating security reports or populating vulnerability dashboards.
Unique: Provides direct access to OSV's comprehensive vulnerability records by ID, including cross-referenced CVE/GHSA data and ecosystem-specific impact information, enabling rich vulnerability context without requiring multiple data sources
vs alternatives: Single source of truth for vulnerability details across multiple ecosystems and advisory formats (CVE, GHSA, etc.), eliminating the need to cross-reference multiple vulnerability databases
Implements OSV vulnerability queries as MCP tools with JSON schema definitions, enabling LLM agents and MCP clients to discover and invoke vulnerability lookups through a standardized tool-calling interface. The MCP server exposes tools for package queries, commit queries, batch queries, and detail lookups, each with defined input schemas and response formats that LLMs can understand and invoke autonomously.
Unique: Exposes OSV vulnerability queries as MCP tools with standardized schemas, enabling LLM agents to autonomously discover and invoke vulnerability checks without hardcoded integrations, following the MCP protocol for tool discovery and invocation
vs alternatives: Enables agentic vulnerability scanning where LLMs can autonomously decide when and how to query OSV based on code context, rather than requiring explicit human-triggered scans or hardcoded CI/CD rules
Abstracts away ecosystem-specific vulnerability data formats and APIs by translating queries across npm, PyPI, Maven, Rust crates, Go modules, and other supported ecosystems into a unified OSV schema. The MCP server handles ecosystem detection, version normalization, and response mapping, returning consistent vulnerability records regardless of the underlying package manager or ecosystem.
Unique: Provides a single, unified interface for querying vulnerabilities across 10+ package ecosystems by leveraging OSV's cross-ecosystem schema, eliminating the need to learn ecosystem-specific vulnerability APIs
vs alternatives: Supports more ecosystems in a single tool than ecosystem-specific scanners (e.g., npm audit only works for npm), making it ideal for polyglot projects and enterprise environments with diverse tech stacks
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 OSV 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
