Exposes yfinance's ticker data fetching as an MCP tool that LLM agents can invoke to retrieve current and historical stock prices. Implements the Model Context Protocol's tool-calling interface, allowing Claude or other MCP-compatible clients to request stock data through standardized JSON-RPC messages without direct library imports. The server wraps yfinance's Ticker class and marshals responses back through MCP's transport layer (stdio or HTTP).
Unique: Wraps yfinance as a standardized MCP tool, enabling seamless integration into multi-tool agent workflows without requiring agents to manage library imports or API authentication directly. Uses MCP's schema-based tool registration to expose yfinance methods as discoverable, type-safe functions.
vs alternatives: Simpler than building custom REST endpoints for yfinance; integrates directly into Claude and other MCP clients without additional infrastructure, whereas direct yfinance usage requires agents to handle library management and error handling themselves.
Retrieves and structures historical open-high-low-close-volume (OHLCV) candlestick data for specified date ranges and intervals (daily, weekly, monthly). Leverages yfinance's built-in resampling and aggregation to convert raw tick data into standardized time-series format. Returns data as JSON arrays suitable for charting libraries or time-series analysis, with automatic handling of market holidays and trading halts.
Unique: Exposes yfinance's pandas-based resampling as an MCP tool, allowing agents to request pre-aggregated historical data without managing DataFrame transformations themselves. Automatically handles timezone normalization and market calendar adjustments.
vs alternatives: More flexible than static CSV exports because agents can request arbitrary date ranges and intervals on-demand; more accessible than raw yfinance because MCP abstracts pandas/numpy complexity into simple JSON responses.
Fetches corporate action history (dividends, stock splits, rights issues) for a given ticker through yfinance's actions API. Structures this data as MCP tool responses, enabling agents to adjust historical price data or calculate total return metrics that account for distributions. Automatically parses yfinance's internal action tables and normalizes dates and amounts.
Unique: Exposes yfinance's actions API as a discrete MCP tool, allowing agents to separately query corporate actions without fetching full price history. Normalizes dividend and split data into consistent JSON schema for downstream calculations.
vs alternatives: Simpler than manually parsing SEC filings or maintaining a corporate actions database; more reliable than web scraping because it leverages yfinance's curated data, though less comprehensive than premium financial data providers like Bloomberg or FactSet.
Retrieves company metadata (sector, industry, market cap, PE ratio, dividend yield, 52-week range) and fundamental metrics from yfinance's info endpoint. Marshals this data through MCP's tool interface, enabling agents to contextualize price data with company fundamentals. Handles missing fields gracefully and normalizes numeric values across different data types.
Unique: Wraps yfinance's info endpoint as an MCP tool, exposing company fundamentals as a queryable resource for agents without requiring direct library access. Normalizes inconsistent field naming and handles null values across different ticker types.
vs alternatives: More accessible than raw yfinance because MCP abstracts data parsing; less comprehensive than dedicated fundamental data APIs (e.g., Alpha Vantage, IEX Cloud) but requires no additional API keys or subscriptions.
Accepts a list of ticker symbols and returns aggregated price/fundamental data for all tickers in a single MCP call. Implements concurrent fetching using Python's asyncio or threading to parallelize yfinance requests, reducing total latency compared to sequential ticker-by-ticker calls. Structures responses as a JSON array indexed by ticker symbol for easy agent consumption.
Unique: Implements concurrent yfinance fetching within a single MCP tool call, reducing round-trip overhead compared to sequential agent calls. Uses asyncio or threading to parallelize I/O-bound network requests while maintaining MCP's synchronous tool interface.
vs alternatives: Faster than agents making individual MCP calls per ticker because it batches network requests; simpler than agents managing their own concurrency because parallelization is handled server-side.
Retrieves exchange rates and forex data for currency pairs (e.g., EUR/USD) using yfinance's ticker support for forex symbols. Enables agents to convert portfolio values across currencies or analyze forex trends. Handles currency pair naming conventions and returns rates with timestamps for time-series analysis.
Unique: Extends yfinance's ticker support to forex symbols, exposing currency data through the same MCP tool interface as stocks. Normalizes forex pair naming and provides time-series rates for currency analysis.
vs alternatives: More integrated than calling separate forex APIs because it uses the same yfinance backend; less comprehensive than dedicated forex platforms (e.g., OANDA, Interactive Brokers) but requires no additional subscriptions.
Implements robust error handling for yfinance failures (invalid tickers, network timeouts, rate limiting) and returns structured error responses through MCP. Validates input parameters (date ranges, ticker formats) before making requests and provides meaningful error messages to agents. Includes optional fallback strategies such as returning cached data or degraded responses when primary data sources fail.
Unique: Wraps yfinance calls with comprehensive input validation and error handling, returning structured error responses that agents can programmatically interpret. Distinguishes between client errors (invalid input), server errors (yfinance unavailable), and rate limiting to enable targeted recovery strategies.
vs alternatives: More reliable than raw yfinance because it validates inputs and handles failures gracefully; simpler than agents implementing their own error handling because validation and error structuring is centralized in the MCP server.
Implements the Model Context Protocol's transport layer, supporting both stdio (for local Claude Desktop integration) and HTTP (for remote MCP hosts). Abstracts transport details from tool implementations, allowing the same yfinance tools to work across different client architectures. Handles JSON-RPC message serialization, request routing, and response marshaling according to MCP specification.
Unique: Implements both stdio and HTTP transport layers for MCP, allowing the same server to work with Claude Desktop (stdio) or remote clients (HTTP). Uses MCP SDK's transport abstraction to decouple tool logic from protocol details.
vs alternatives: More flexible than stdio-only implementations because it supports both local and remote deployment; simpler than building custom protocol handlers because it leverages the MCP SDK's transport layer.
Scrapes a single URL and converts HTML content to clean markdown using Firecrawl's content extraction pipeline. The firecrawl_scrape tool accepts a URL and optional parameters (formats, headers, wait time, screenshot capability) and returns structured markdown output with automatic cleanup of boilerplate, navigation, and ads. Implements MCP tool handler pattern that marshals arguments through the @mendable/firecrawl-js client library to Firecrawl's backend processing engine.
Unique: Integrates Firecrawl's proprietary content extraction engine (which uses ML-based boilerplate removal and semantic content identification) through MCP protocol, enabling AI agents to access production-grade web scraping without managing browser automation or parsing logic themselves. The markdown conversion is handled server-side rather than client-side, reducing latency and ensuring consistent output formatting.
vs alternatives: Cleaner markdown output than regex-based scrapers like Cheerio or Puppeteer-only solutions because Firecrawl uses ML models to identify main content; simpler than self-hosted solutions because it's fully managed and requires only an API key.
Scrapes multiple URLs in a single operation using Firecrawl's batch processing pipeline. The firecrawl_batch_scrape tool accepts an array of URLs and shared options, submitting them to Firecrawl's backend which processes them in parallel and returns an array of markdown-converted content objects. Implements batching through the @mendable/firecrawl-js client's batch method, which handles request queuing, parallel execution, and result aggregation without requiring client-side coordination.
Unique: Implements server-side parallel batch processing through Firecrawl's backend rather than client-side loop iteration, reducing network round-trips and enabling true concurrent scraping. The batch operation is atomic from the MCP client perspective — a single tool call returns all results, simplifying agent orchestration logic.
More efficient than sequential scraping loops because Firecrawl handles parallelization server-side; simpler than managing Promise.all() with individual scrape calls because batching is a first-class operation with built-in error handling.

Unique: Provides production-ready Docker packaging with environment-based configuration, enabling zero-code deployment to containerized infrastructure. The Dockerfile handles Node.js runtime setup and dependency installation, reducing deployment complexity.
vs alternatives: Simpler than manual deployment because Docker handles environment setup; more portable than binary distribution because containers run consistently across platforms.
Registers the Firecrawl MCP server in the Smithery registry, enabling one-click installation and discovery through Smithery's MCP client marketplace. The server is published to Smithery with metadata (description, tags, configuration schema) allowing users to discover and install it without manual setup. Smithery handles server distribution, version management, and client integration.
Unique: Leverages Smithery's MCP server registry to enable one-click installation without manual configuration, reducing friction for end users. Smithery handles server discovery, versioning, and client integration, abstracting deployment complexity.
vs alternatives: More user-friendly than manual installation because Smithery handles discovery and setup; more discoverable than GitHub-only distribution because Smithery provides a centralized marketplace.
Supports connecting to self-hosted Firecrawl instances in addition to Firecrawl's cloud service through configurable API endpoint. The FIRECRAWL_API_URL environment variable allows operators to specify a custom Firecrawl endpoint, enabling deployment scenarios where Firecrawl runs on-premises or in a private cloud. The @mendable/firecrawl-js client library handles endpoint abstraction, routing all API calls to the configured endpoint.
Unique: Enables flexible deployment by supporting both cloud and self-hosted Firecrawl instances through simple endpoint configuration, allowing operators to choose deployment model without code changes. The endpoint abstraction is handled by @mendable/firecrawl-js, making self-hosted support transparent to MCP server code.
vs alternatives: More flexible than cloud-only solutions because self-hosted option is available; simpler than maintaining separate server implementations because endpoint configuration is unified.
Discovers all URLs within a website by crawling from a base URL and building a sitemap-like structure. The firecrawl_map tool accepts a base URL and optional parameters (max depth, include patterns, exclude patterns) and returns a hierarchical array of discovered URLs with metadata about page structure. Uses Firecrawl's crawler to traverse internal links up to specified depth, filtering by inclusion/exclusion patterns, and returns the complete URL graph without fetching full page content.
Unique: Provides lightweight URL discovery without content extraction, allowing agents to plan scraping strategy before committing credits to full content fetches. The depth-based crawling with pattern filtering enables selective discovery — agents can discover only URLs matching specific criteria (e.g., /blog/* paths) without exploring entire site.
vs alternatives: More efficient than scraping every page to build a sitemap because it skips content extraction; more reliable than parsing robots.txt or sitemaps.xml because it performs actual crawling and discovers dynamically-linked content.
Crawls an entire website and extracts content from all discovered pages in a single asynchronous operation. The firecrawl_crawl tool accepts a base URL and options (max pages, allowed domains, exclude patterns, scrape options) and returns a crawl ID for polling. The crawler discovers URLs, extracts markdown content from each page, and stores results server-side. Clients poll firecrawl_crawl_status to retrieve results as they complete, implementing an async job pattern rather than blocking until completion.
Unique: Implements server-side asynchronous crawling with job-based result retrieval, decoupling the crawl initiation from result consumption. The MCP server handles polling coordination through firecrawl_crawl_status, allowing AI agents to initiate long-running crawls and check progress without blocking. Firecrawl's backend manages the entire crawl lifecycle including URL discovery, content extraction, and result storage.
vs alternatives: More scalable than sequential scraping because crawling happens server-side in parallel; simpler than managing Puppeteer/Playwright browser pools because Firecrawl abstracts browser automation and handles rate limiting internally.
Polls the status of an in-progress or completed website crawl and retrieves extracted content. The firecrawl_crawl_status tool accepts a crawl ID and returns current progress (pages crawled, pages remaining, completion percentage), status state (running/completed/failed), and paginated results. Implements polling pattern where clients repeatedly call this tool with the same crawl ID to check progress and incrementally retrieve content as pages are processed, supporting streaming-like result consumption.
Unique: Provides non-blocking status and result retrieval for asynchronous crawls, enabling agents to manage long-running operations without blocking. The polling pattern with pagination allows incremental result consumption — agents can start processing results before the entire crawl completes, reducing end-to-end latency for large crawls.
vs alternatives: More flexible than blocking crawl operations because agents can check progress and retrieve partial results; simpler than webhook-based result delivery because polling requires no external infrastructure setup.
