clear_thoughts
Clear all thoughts recorded in the current session. Use this to start fresh if the thinking process needs to be reset.
LABSCO SUMMARY
A place to put reasoning that a long tool chain would otherwise lose.
The write half is deliberately inert; the read half is the point. get_thoughts recovers what was decided earlier in the same session, which is exactly what drops out of context during a long chain of calls, policy checks or sequential decisions. The scope is one session — clear_thoughts resets it and nothing here carries a record from one session into the next.
What it is
A session-scoped thought log: four tools that write to and read from a record of the model's own reasoning, with no external system behind them.
What you get
- think appends a thought to the session log — its own description is explicit that it obtains no new information and changes nothing else
- get_thoughts returns everything recorded in the current session, so a decision made twenty calls ago can be read back verbatim
- clear_thoughts resets the log when the reasoning needs to start over
- get_thought_stats returns statistics over what has been recorded
Requirements
Nothing — no account, no key.
Setup effort
One command — npx -y @cgize/mcp-think-tool
USE CASES
01
Keeping a long chain of tool calls on the rails
An intermediate conclusion goes into the log instead of being carried in the reply, and the log can be read back mid-chain when the next decision depends on what was already settled.
02
Reconstructing why the answer came out that way
After the fact, the log is the reasoning trail: every recorded thought in the session, with statistics over what accumulated.
03
Starting over after a line of reasoning dead-ends
Clearing the session's thoughts drops the abandoned trail so the next chain does not read it back as context, and thinking resumes on an empty log.
4 tools
Counted once with only startup setup. Other versions, modes or optional credentials may expose a different list.
get_thought_stats
Get statistics about the thoughts recorded in the current session to analyze your thinking process.
get_thoughts
Retrieve all thoughts recorded in the current session to review your reasoning process.
think
Use this tool to think about something. It will not obtain new information or change anything, but just append the thought to the log. Use it when complex reasoning or cache memory is needed, especially during long chains of tool calls, policy adherence scenarios, or sequential decision making.
