Implements a Python-based MCP server that launches as a subprocess and communicates with MCP clients (Claude Desktop) via stdio, translating high-level tool requests into structured MCP protocol messages. The server registers 13 tools dynamically, handles request routing through call_tool and list_tools handlers, and manages the full MCP lifecycle including initialization and tool discovery without requiring direct file system access to Obsidian vaults.
Unique: Uses MCP protocol as the primary abstraction layer rather than direct REST API exposure, enabling seamless integration with Claude Desktop's tool-calling framework while maintaining clean separation between protocol handling (server.py) and business logic (tools.py, obsidian.py)
vs alternatives: Provides standardized MCP protocol compliance vs custom REST wrappers, enabling native Claude Desktop integration without requiring custom client code or authentication management
Implements file reading capability by translating MCP tool requests into HTTP GET calls to Obsidian's REST API vault/read endpoint, parsing JSON responses containing file metadata and content, and returning formatted text content to the client. Supports reading any file type stored in the vault (markdown, JSON, images as base64) with automatic error handling for missing files and permission issues.
Unique: Abstracts Obsidian's REST API read endpoint through a ToolHandler pattern that formats responses as TextContent objects, enabling seamless integration with Claude's context window while handling encoding for binary content automatically
vs alternatives: Safer than direct file system reads because it respects Obsidian's internal state management and plugin hooks, vs alternatives that bypass Obsidian entirely and risk vault corruption
Implements the MCP server using Python's asyncio framework with async/await syntax, enabling non-blocking I/O for HTTP requests to Obsidian's REST API. The implementation uses async context managers for resource cleanup and async generators for streaming responses, allowing the server to handle multiple concurrent client requests without blocking.
Unique: Uses Python's asyncio framework with async/await syntax for the MCP server loop, enabling non-blocking I/O and concurrent request handling while maintaining clean, readable code structure
vs alternatives: More responsive than synchronous servers because multiple concurrent requests don't block each other, and better resource utilization because threads aren't created per request
Implements file listing capability by querying Obsidian's REST API vault/list endpoint to retrieve directory contents with file metadata (size, type, modification date). The implementation supports recursive directory traversal and filtering by file type, enabling clients to explore vault structure and discover files without direct file system access.
Unique: Provides recursive directory traversal through Obsidian's REST API rather than direct file system access, respecting Obsidian's vault structure and ignoring system files or ignored directories
vs alternatives: More reliable than file system traversal because it only returns files that Obsidian recognizes as vault content, excluding system files, caches, and ignored directories
Implements tag-based filtering by parsing note frontmatter and content to extract tags, then filtering notes by tag matches. The implementation supports both YAML frontmatter tags and inline tag syntax (#tag), enabling clients to discover notes by topic without full-text search.
Unique: Extracts tags from both YAML frontmatter and inline #tag syntax, supporting multiple tagging conventions within the same vault and enabling flexible tag-based organization
vs alternatives: More flexible than search-based filtering because it respects Obsidian's tag structure and supports hierarchical tag relationships, vs full-text search which treats tags as regular text
Implements link traversal capability by parsing note content to extract wiki-style links ([[note-name]]) and backlinks, enabling clients to navigate the knowledge graph and discover related notes. The implementation builds a link graph by analyzing note content and provides methods to traverse forward links (outgoing) and backlinks (incoming).
Unique: Parses note content to extract wiki-style links and builds a bidirectional link graph, enabling both forward link traversal (what does this note link to) and backlink traversal (what notes link to this)
vs alternatives: More powerful than simple link following because it supports bidirectional traversal and can analyze the full knowledge graph structure, vs alternatives that only support forward links
Implements file writing capability by translating MCP tool requests into HTTP POST calls to Obsidian's REST API vault/write endpoint, supporting both full file replacement and targeted content patching via search-and-replace operations. The implementation validates file paths, handles encoding for text and binary content, and provides atomic write semantics through Obsidian's internal file handling.
Unique: Supports both full-file replacement and targeted search-and-replace patching through the same ToolHandler interface, enabling both bulk updates and surgical edits without requiring the client to manage merge logic or conflict resolution
vs alternatives: More reliable than direct file system writes because Obsidian's REST API enforces its internal consistency checks and plugin hooks, preventing vault corruption from concurrent access or malformed content
Implements search capability by translating MCP tool requests into HTTP POST calls to Obsidian's REST API vault/search endpoint with query parameters, returning ranked lists of matching files with excerpt snippets and relevance scores. The implementation supports boolean operators, phrase matching, and field-specific searches (title, content, tags) through Obsidian's native search syntax.
Unique: Leverages Obsidian's native search engine through the REST API rather than implementing custom indexing, ensuring search results reflect Obsidian's actual vault state including recent edits and plugin-generated content
vs alternatives: More accurate than external search indexes because it queries Obsidian's live index rather than a potentially stale external database, and supports Obsidian-specific search syntax (tags, links, metadata)

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 Obsidian at 23/100.

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
