sequential-thinking

sequential-thinking is an MCP server for Claude Code, Codex, Cursor, Gemini CLI, OpenCode from virtengine/bosun. Its token cost is not measured, scanned A, original, Apache-2.0.

A structured reasoning tool that lets an agent break a problem into steps and revise those steps as it works. It runs locally through the Model Context Protocol, a standard way for agents to call tools.

In plain words
What is it for?
Use it for tasks that benefit from step-by-step analysis and revisable intermediate thoughts.
Why use it?
It helps keep complex reasoning organised instead of handling every part as one unstructured thought.

Written for no agent in particular: it speaks MCP, so any client can run it.

One of 4 entries in mcp.json upstream. Installing this one merges just its entry into your config; the other 3 are separate, each on its own page.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Security

Grade A, and why

sequential-thinking scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

This page is one entry in a file that holds 4. Installing the file brings all of them; each is measured and scanned on its own page.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
