Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Step-by-step reflective thinking: record, revise, and branch thought chains.
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
The registry does not list a required key, though some servers ask you to sign in on first use.
It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Think in steps, out loud, with a server keeping the thread.
Some problems do not yield to a single pass. You form a first idea, poke at it, realise the second step contradicts the first, double back, try a different route from an earlier point, and only then see the shape of the answer. thinkstep is the notebook for that process: an MCP server with one tool, sequentialthinking, that records a chain of thoughts one step at a time and keeps the whole history — revisions and side branches included — straight for you.
Each call adds one thought. You say where you are (thoughtNumber), roughly how far you think you have to go (totalThoughts), and whether you need another step. If the chain outgrows your estimate, the server raises the total for you instead of complaining. When a step rethinks an earlier one, flag it as a revision and point at the thought it reconsiders. When you want to explore a different route without losing the main line, fork a named branch from an earlier thought; every response lists the branch ids created so far, so you always know which threads are open.
State lives in the server process for the length of the session. Nothing is written to disk, nothing leaves the machine, and closing the session closes the notebook.

| parameter | type | required | meaning |
|---|---|---|---|
thought | string | yes | Your current thinking step |
nextThoughtNeeded | boolean | yes | Whether another thought step is needed |
thoughtNumber | integer | yes | Current thought number (numeric value, e.g., 1, 2, 3) |
totalThoughts | integer | yes | Estimated total thoughts needed (numeric value, e.g., 5, 10) |
isRevision | boolean | no | Whether this revises a previous thought |
revisesThought | integer | no | Which thought is being reconsidered |
branchFromThought | integer | no | Branching point thought number |
branchId | string | no | Branch identifier |
needsMoreThoughts | boolean | no | If more thoughts are needed |
A branch is tracked when a thought carries both branchFromThought and branchId. A revision is recorded with isRevision: true and revisesThought set to the number of the thought it rethinks; the original stays in the history.
Every accepted thought returns a JSON summary:
{
"thoughtNumber": 2, "totalThoughts": 5, "nextThoughtNeeded": true, "branches": ["cheaper-route"], "thoughtHistoryLength": 4 }
thoughtNumber / totalThoughts — where the chain stands. If thoughtNumber exceeds the estimated totalThoughts, the total is raised to thoughtNumber.nextThoughtNeeded — whether the chain continues. Sending needsMoreThoughts: true also reports this as true.branches — the id of every branch created so far, in creation order.thoughtHistoryLength — how many thoughts the server has recorded, including this one.Missing or mistyped fields are refused with an error result (isError) naming the offending field; nothing is recorded for a rejected call.
