Clear Thought 1.5CAUTION
OG Sequential Thinking fork, v1.5
Overview
From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.
[](https://smithery.ai/server/@waldzellai/clear-thought-onepointfive)
A Model Context Protocol (MCP) server that provides a unified reasoning tool with multiple operations, including systematic thinking, mental models, debugging approaches, and interactive notebook capabilities for enhanced problem-solving. This server exposes a single clear_thought tool with a comprehensive suite of operations to facilitate complex reasoning tasks, plus interactive Srcbook notebook resources.
🚀 New: Modular Architecture
The codebase has been completely refactored from a monolithic 2867-line file into a clean, modular architecture with 38 separate operations organized by category. Each operation is now self-contained, making the codebase more maintainable, testable, and extensible.
Operations
The clear_thought tool provides the following operations. For detailed information on parameters, please refer to the operations guide resource at guide://clear-thought-operations.
Core Thinking Operations
- sequential_thinking: Executes a chain-of-thought process. Can be configured to use different reasoning patterns like 'tree', 'beam', 'mcts', 'graph', or 'auto'.
- mental_model: Applies a specified mental model to a problem.
- debugging_approach: Guides through a structured debugging process.
- creative_thinking: Facilitates idea generation and exploration.
- visual_reasoning: Works with diagrams and visual structures.
- metacognitive_monitoring: Monitors and assesses the reasoning process itself.
- scientific_method: Follows the steps of the scientific method for inquiry.
Collaborative & Decision Operations
- collaborative_reasoning: Simulates a multi-persona discussion to explore a topic from different viewpoints.
- decision_framework: Uses a structured framework to analyze options and make decisions.

Questions
What is the Clear Thought 1.5 MCP server?
OG Sequential Thinking fork, v1.5
What tools does Clear Thought 1.5 expose?
2 in total: 0 read-only, 0 that write, and 2 that can delete or overwrite (clear_thought, unifiedreasoning). Every one is listed on this page with its risk.
Is Clear Thought 1.5 safe to connect to an agent?
With care. The audit graded it B (89/100) and found 11 things worth knowing before you trust this server, listed below with the exact line each was found on. Separately from the audit: 2 of its tools can destroy data, so scope the token you give it to what you actually need.
What credentials does Clear Thought 1.5 need?
It reads OTEL_AUTH_TOKEN and SHINZO_TOKEN from the environment. Give it a token scoped to the least it needs — an agent that can be talked into calling a tool can be talked into calling it with your credentials.
How does Clear Thought 1.5 run?
It speaks stdio, so it runs as a local process your client starts. It is published on npm as @waldzellai/clear-thought-onepointfive at 0.2.1.
How current is this page?
The grade is for one exact copy of the source (9c308730429c), read on 2026-10-08. The repository is watched and re-audited when it changes.
