Implements a structured thinking tool that allows LLM clients to decompose complex problems into sequential reasoning steps with explicit branching, revision, and hypothesis tracking. The server exposes a single MCP tool that clients invoke to create hierarchical thought structures where each step can spawn multiple branches representing alternative reasoning paths, enabling non-linear exploration of solution spaces while maintaining full audit trails of the reasoning process.
Unique: Provides native MCP tool interface for structured branching reasoning with explicit hypothesis tracking and revision support, implemented as a reference server demonstrating MCP's tool capability primitive. Unlike generic prompt-based chain-of-thought, this exposes reasoning structure as first-class data that clients can inspect, manipulate, and persist independently.
vs alternatives: Offers protocol-level reasoning structure (via MCP tools) rather than relying on LLM output parsing, enabling deterministic branch tracking and client-side reasoning tree manipulation that generic prompt engineering cannot achieve.
Implements the MCP tool capability primitive by registering a structured tool schema that defines the reasoning interface (step creation, branching, revision operations) and handling tool invocation requests from MCP clients via JSON-RPC protocol. The server uses TypeScript SDK abstractions to define tool parameters (problem statement, step content, branch metadata) with JSON schema validation, then routes incoming tool calls to internal reasoning handlers that construct and return thought tree structures.
Unique: Demonstrates MCP tool capability as a reference implementation using TypeScript SDK, showing proper schema definition, parameter validation, and JSON-RPC request/response handling patterns. Serves as educational example for developers building their own MCP servers rather than a production tool framework.
vs alternatives: Official reference implementation from MCP steering group provides authoritative patterns for tool registration and invocation; more reliable for learning than community examples, though intentionally simplified for clarity over feature completeness.
Manages an in-memory hierarchical data structure representing reasoning steps as nodes with parent-child relationships, supporting operations like step creation, branching (creating sibling alternatives), revision (updating step content), and hypothesis labeling. The server maintains tree state during a session, allowing clients to reference previous steps by ID when creating new branches, and provides mechanisms to traverse the tree structure to retrieve reasoning history and branch relationships.
Unique: Implements hierarchical reasoning state as a first-class MCP capability, allowing clients to explicitly construct and navigate branching thought trees rather than parsing LLM text output. Uses parent-child reference semantics to support arbitrary branching depth and revision tracking without requiring external graph databases.
vs alternatives: Provides structured reasoning state management that generic prompt-based chain-of-thought cannot offer; enables deterministic branch tracking and client-side tree manipulation, though at the cost of requiring explicit client integration rather than working with any LLM via prompting alone.
Tracks modifications to reasoning steps and maintains metadata about hypothesis alternatives, allowing clients to record when a step is revised, why it was changed, and which hypotheses were explored or abandoned. The server stores revision history and hypothesis labels alongside step content, enabling clients to query the reasoning trajectory and understand decision points where the LLM chose one path over alternatives.
Unique: Provides explicit revision and hypothesis tracking as part of the reasoning tool interface, allowing clients to annotate why steps were changed and which alternatives were considered. Unlike generic reasoning logs, this captures structured metadata about decision points and abandoned paths.
vs alternatives: Enables systematic analysis of reasoning alternatives and revision decisions that text-based chain-of-thought logs cannot support; requires explicit client integration but provides richer interpretability data for reasoning analysis.
Implements the MCP server lifecycle including initialization, client connection handling, and graceful shutdown, using the TypeScript SDK's server abstractions. The server registers itself with the MCP protocol, advertises its capabilities (tools, resources, prompts) to connecting clients, and maintains session state for each connected client. Handles transport-level concerns like JSON-RPC message routing and error propagation through the MCP protocol layer.
Unique: Demonstrates MCP server lifecycle patterns using official TypeScript SDK, showing proper initialization, capability advertisement, and client session handling. Serves as reference for developers building their own MCP servers with correct protocol compliance.
vs alternatives: Official reference implementation ensures protocol compliance and best practices; more reliable than community examples for understanding correct MCP server patterns, though intentionally simplified for educational clarity.
Serializes hierarchical thought trees and reasoning metadata into JSON structures that MCP clients can consume, parse, and integrate into their own reasoning workflows. The server formats tool responses as structured JSON containing step IDs, branch relationships, content, and metadata, enabling clients to reconstruct the reasoning tree, visualize it, or feed it back into subsequent reasoning iterations. Supports round-trip serialization where clients can submit previous reasoning context to continue or refine reasoning.
Unique: Provides structured JSON serialization of reasoning trees that enables client-side tree visualization, manipulation, and round-trip context passing. Unlike text-based reasoning output, this maintains tree structure and relationships in machine-readable format.
vs alternatives: Enables rich client-side reasoning UI and context management that plain text chain-of-thought output cannot support; requires explicit client integration but provides better composability with downstream reasoning or visualization systems.
Serves as an official reference implementation for MCP server developers, demonstrating TypeScript SDK usage patterns, proper tool registration, error handling, and protocol compliance. The codebase is intentionally simplified and well-documented to serve as a learning resource for developers building their own MCP servers, rather than a feature-complete production system. Includes examples of how to structure tool handlers, manage server state, and respond to client requests according to MCP specifications.
Unique: Official reference implementation maintained by MCP steering group, providing authoritative patterns for tool registration, error handling, and protocol compliance. Intentionally simplified for educational clarity rather than feature completeness, making it ideal for learning but requiring enhancement for production use.
vs alternatives: Official status and steering group maintenance ensure accuracy and alignment with MCP specifications; more reliable for learning than community examples, though community servers may demonstrate more advanced features or production patterns.
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.

Supports both cloud and self-hosted Firecrawl instances through configuration.
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.
