Breaks down complex problems into numbered sequential thoughts with full state management, supporting non-linear exploration through branching and revision. Uses a ThoughtData interface to track thought content, position, branch relationships, and associated recommendations. The ToolAwareSequentialThinkingServer class maintains a thought_history array and branches record, allowing LLMs to explore alternative solution paths while preserving the original reasoning chain.
Unique: Implements thought decomposition as a stateful MCP server with explicit branching support via a branches record, allowing LLMs to explore multiple solution paths while maintaining the full reasoning history. Unlike simple chain-of-thought prompting, this provides server-side state management and structured metadata for each thought step.
vs alternatives: Provides server-side thought state management with branching support, whereas most chain-of-thought implementations rely on prompt-based reasoning without persistent state tracking or explicit revision paths.
Analyzes each sequential thinking step and recommends which MCP tools should be applied next, returning structured recommendations with confidence scores and rationales. The processThought() method evaluates available_tools (stored as a Map of registered MCP tools) against the current thought context, generating StepRecommendation objects that include tool names, confidence levels, and reasoning. This enables LLMs to make informed tool-selection decisions rather than blindly attempting all available tools.
Unique: Implements tool recommendations as a first-class server capability that analyzes thought context and returns scored suggestions, rather than embedding tool selection logic in the LLM prompt. Uses a Map-based tool registry that can be queried during recommendation generation, enabling dynamic analysis of available tools.
vs alternatives: Provides structured, scored tool recommendations with rationales, whereas most LLM agents rely on prompt engineering or simple tool availability lists without confidence-based prioritization.
Maintains a Map of registered MCP tools with their schemas and metadata, enabling the server to discover available tools and analyze their applicability to problem-solving steps. The available_tools Map stores tool definitions that can be queried during recommendation generation. Version 0.0.3 added explicit tool listing capabilities, allowing clients to request the full inventory of registered tools and their specifications.
Unique: Implements tool discovery as a queryable Map-based registry within the MCP server, allowing clients to inspect available tools and their schemas. This enables the recommendation engine to analyze tool applicability dynamically without hardcoding tool knowledge.
vs alternatives: Provides server-side tool discovery and registry management, whereas many LLM agents hardcode tool lists in prompts or require clients to manage tool availability externally.
Manages thought history with configurable memory limits to prevent unbounded growth of the thought_history array. Version 0.0.3 added explicit memory management capabilities, allowing configuration of maximum history size and automatic pruning of older thoughts when limits are exceeded. This prevents memory exhaustion in long-running reasoning sessions while preserving recent context.
Unique: Implements configurable history limits as a first-class feature of the sequential thinking server, with automatic pruning when limits are exceeded. This prevents memory exhaustion in long-running sessions while maintaining recent context for reasoning.
vs alternatives: Provides explicit, configurable memory management for thought history, whereas most reasoning systems either accumulate unbounded history or require manual cleanup logic in client code.
Enables non-linear problem-solving by supporting branching where the LLM can explore alternative solution paths and revise previous thoughts. The branches record maps branch IDs to separate thought arrays, allowing the server to maintain multiple solution hypotheses simultaneously. When a branch is created, a new thought array is initialized; when a branch is merged or abandoned, the server can switch context between branches without losing the original reasoning chain.
Unique: Implements branching as a first-class feature using a branches record that maps branch IDs to separate thought arrays, enabling true parallel exploration of solution paths. This is distinct from simple undo/redo, as multiple branches can coexist and be compared.
vs alternatives: Provides explicit branching support for parallel hypothesis exploration, whereas most reasoning systems use linear thought sequences or simple undo/redo without true branching capability.
Validates incoming thought data against a SequentialThinkingSchema defined using valibot, ensuring type safety and correctness before processing. The schema enforces required fields (thought content, thought_number), optional fields (branch_id, recommendations), and data type constraints. This validation occurs before the processThought() method executes, preventing malformed thoughts from corrupting server state.
Unique: Uses valibot for runtime schema validation integrated with the MCP protocol via @tmcp/valibot, providing both compile-time TypeScript type safety and runtime validation. This is more robust than simple type checking and enables detailed error reporting.
vs alternatives: Provides runtime schema validation with valibot, whereas many MCP servers rely on TypeScript types alone without runtime validation, risking malformed data from non-TypeScript clients.
Implements the Model Context Protocol using tmcp (v1.16.1) instead of the original @modelcontextprotocol/sdk, providing type-safe MCP communication over standard I/O. The ToolAwareSequentialThinkingServer class extends or integrates with tmcp's server base, handling MCP message serialization, tool resource definitions, and protocol compliance. Version 0.0.4 migrated to tmcp for improved type safety and maintenance.
Unique: Uses tmcp (Type-safe Model Context Protocol) for MCP implementation, providing type-safe protocol handling with automatic serialization/deserialization. This replaces the original @modelcontextprotocol/sdk with a more modern, type-safe alternative.
vs alternatives: Provides type-safe MCP protocol implementation via tmcp with automatic message handling, whereas raw MCP implementations require manual JSON-RPC serialization and error handling.
Enriches each thought with associated StepRecommendation objects that include tool suggestions, confidence scores, and rationales. When a thought is processed, the server analyzes the context and generates recommendations that are attached to the ThoughtData object. This allows clients to access both the raw thought and the server's analysis of what tools should be applied next, creating a rich decision context for the LLM.
Unique: Attaches structured recommendations directly to each thought as metadata, enabling clients to see both the reasoning step and the server's analysis of next steps in a single object. This creates a rich decision context without requiring separate recommendation queries.
vs alternatives: Provides recommendations as first-class thought metadata rather than separate API calls, reducing latency and keeping reasoning and recommendations tightly coupled.
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 mcp-sequentialthinking-tools at 32/100.

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
