- Enable "Start Automatically" if you want the plugin to start when Highlight launches
From the repository
uv --directory "/path/to/sequential-thinking-mcp" run main.py
pip install "mcp[cli]"
```python
thought
(string): The current thinking step
thoughtNumber
(integer): Current thought number
totalThoughts
(integer): Estimated total thoughts needed
nextThoughtNeeded
(boolean): Whether another thought step is needed
isRevision
(boolean, optional): Whether this revises previous thinking
revisesThought
(integer, optional): Which thought is being reconsidered
branchFromThought
(integer, optional): Branching point thought number
branchId
(string, optional): Branch identifier
needsMoreThoughts
(boolean, optional): If more thoughts are needed
The server provides a tool called sequential_thinking with the following parameters:
- thought (string): The current thinking step
- thoughtNumber (integer): Current thought number
- totalThoughts (integer): Estimated total thoughts needed
- nextThoughtNeeded (boolean): Whether another thought step is needed
- isRevision (boolean, optional): Whether this revises previous thinking
- revisesThought (integer, optional): Which thought is being reconsidered
- branchFromThought (integer, optional): Branching point thought number
- branchId (string, optional): Branch identifier
