Exposes yfinance's stock ticker data fetching through the Model Context Protocol, allowing AI agents to query current and historical stock prices by ticker symbol. Implements MCP resource endpoints that wrap yfinance's Ticker.history() and Ticker.info methods, translating HTTP/JSON requests into structured financial data responses with OHLCV (open, high, low, close, volume) fields and metadata.
Unique: Wraps yfinance as an MCP server, enabling direct integration with Claude and other MCP-compatible AI agents without custom API wrappers; uses MCP's resource and tool abstractions to expose ticker data as first-class protocol primitives rather than generic function calls
vs alternatives: Simpler than building a custom REST API wrapper around yfinance; tighter integration with Claude's native MCP support compared to generic HTTP tool calling
Supports querying multiple stock tickers in a single MCP call, aggregating results into a unified response structure. Implements parallel or sequential fetching of yfinance Ticker objects, combining OHLCV data, fundamentals, and metadata across symbols, then normalizing into a consistent JSON schema for downstream processing by AI agents.
Unique: Implements batch ticker fetching as a single MCP tool invocation, reducing round-trip overhead compared to calling single-ticker endpoints repeatedly; normalizes heterogeneous yfinance responses into a consistent schema for agent consumption
vs alternatives: More efficient than agents making N separate API calls for N tickers; cleaner than agents managing their own batching logic outside the MCP boundary
Exposes yfinance's Ticker.history() method through MCP, allowing agents to fetch historical price data at configurable intervals (daily, weekly, monthly). Translates interval parameters into yfinance's period/interval arguments, returns time-indexed DataFrames converted to JSON arrays with timestamp, open, high, low, close, volume, and adjusted close fields.
Unique: Parameterizes yfinance's interval selection (daily/weekly/monthly) as MCP tool arguments, allowing agents to dynamically request different granularities without code changes; converts pandas DataFrames to JSON with explicit timestamp normalization for agent consumption
vs alternatives: More flexible than fixed-interval endpoints; avoids agents needing to manage pandas or numpy dependencies directly
Exposes yfinance's Ticker.info dictionary through MCP, extracting key fundamental metrics (PE ratio, market cap, dividend yield, earnings per share, 52-week high/low, etc.). Implements selective field extraction from yfinance's unstructured info dict, normalizing null/missing values and converting numeric strings to proper types for agent consumption.
Unique: Selectively extracts and normalizes yfinance's unstructured Ticker.info dict into a clean schema, handling type conversions and null values; exposes fundamental metrics as a dedicated MCP tool rather than bundling with price data
vs alternatives: Cleaner than agents parsing raw yfinance dicts; more focused than generic financial data APIs that require separate subscriptions
Implements the Model Context Protocol server specification, registering yfinance capabilities as MCP resources and tools with proper schema definitions. Uses MCP's JSONSchema for input validation, implements request/response serialization, and handles MCP lifecycle (initialization, capability advertisement, error handling). Enables Claude and other MCP clients to discover and invoke yfinance functions with type-safe arguments.
Unique: Implements full MCP server lifecycle (initialization, capability advertisement, request handling) as a Python MCP server, enabling seamless integration with Claude and other MCP clients; uses JSONSchema for declarative tool definitions rather than runtime type checking
vs alternatives: Tighter integration with Claude than generic REST APIs; avoids custom HTTP server boilerplate by leveraging MCP's standardized protocol
Implements input validation for ticker symbols and date parameters, catching invalid tickers early and returning structured error responses via MCP. Validates ticker format (alphanumeric, length constraints), date range logic (start < end), and handles yfinance exceptions (network errors, invalid symbols) by translating them into MCP error responses with descriptive messages for agent consumption.
Unique: Implements input validation at the MCP boundary before invoking yfinance, reducing wasted API calls and providing early feedback; translates yfinance exceptions into MCP-compliant error responses with structured metadata
vs alternatives: Prevents agents from making invalid yfinance calls; cleaner error handling than agents parsing raw exceptions
Handles common ticker symbol variations and aliases (e.g., 'Apple' → 'AAPL', 'BRK.A' → 'BRK-A'), normalizing user input before querying yfinance. Implements a mapping layer for common aliases and case-insensitive matching, allowing agents to accept natural language ticker references and convert them to valid yfinance symbols.
Unique: Implements a ticker normalization layer before yfinance calls, allowing agents to accept natural language or alternative formats; uses a static alias mapping for common variations rather than external symbol resolution services
vs alternatives: Simpler than agents managing their own normalization logic; avoids dependency on external symbol resolution APIs
Provides a runnable MCP server implementation with standard lifecycle hooks (startup, shutdown, error recovery). Implements stdio-based MCP transport for local execution or can be deployed as a subprocess managed by MCP clients (Claude Desktop, custom hosts). Handles graceful shutdown, resource cleanup, and connection state management for reliable agent integration.
Unique: Implements a complete MCP server with lifecycle management, using stdio transport for local execution; handles initialization, capability advertisement, and graceful shutdown without requiring external process managers
vs alternatives: Simpler deployment than custom REST API servers; integrates directly with Claude Desktop without additional infrastructure
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 yfinance-mcp-server2 at 25/100. yfinance-mcp-server2 leads on ecosystem, while Supabase is stronger on quality.

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
