ultrabrain-mcp

A local MCP reasoning gate that enables structured engineering thought through step-by-step reasoning, branching, merging, validation, and quality metrics without calling external LLM APIs.

README

ultrabrain-mcp

LCV's local MCP reasoning gate for structured engineering thought.

Install. npm install -g @lcv-ideas-software/ultrabrain-mcp from npmjs.com, or npm install -g @lcv-ideas-software/ultrabrain-mcp --registry=https://npm.pkg.github.com from the GitHub Packages mirror.

Status. Latest release target: v01.01.00 for npm package 1.1.0. First publication started at v01.00.00. Public GitHub tags use the LCV display convention v00.00.00; npm keeps normal SemVer.

Release

Release	Package	Date	Notes
`v01.01.00`	`1.1.0`	2026-05-12	Refinements for depth enforcement, active thought-reference validation, update record returns, real markdown merge output, optional file persistence, and expanded smoke coverage.
`v01.00.00`	`1.0.0`	2026-05-12	First LCV Ultrabrain MCP release: branded tool surface, session lifecycle, branching, merging, validation, analysis, prompts, resources, Pages, CI, publish, and StepSecurity baseline.

What It Does

ultrabrain-mcp is an LCV-created MCP server for local, structured reasoning before engineering work is closed. It gives agents a single branded gate for:

step-by-step reasoning with branches and revisions;
quality metrics, confidence, budget mode, and meta checkpoints;
bias detection and counterexample prompts;
explicit evidence, assumptions, alternatives, risks, and next actions;
session review, validation, metrics, export, prompts, and resources.

The server does not call external LLM APIs. It is a local MCP reasoning scratchpad and quality gate, so source code and private task context stay inside the active MCP host.

Tools

Tool	Purpose
`ultrabrain_start`	Create a reasoning session and optionally seed the first thought.
`ultrabrain_think`	Append the canonical Ultrabrain reasoning step.
`ultrabrain_update`	Strengthen an existing thought with evidence, risks, confidence, or metrics.
`ultrabrain_branch`	Create or continue an alternative reasoning path.
`ultrabrain_merge`	Merge branch insights into a synthesis, best-evidence path, or decision.
`ultrabrain_validate`	Check evidence, alternatives, verification, bias, and closure gaps.
`ultrabrain_analyze`	Summarize quality, confidence, labels, bias counts, and recommendations.
`ultrabrain_review`	Render a session as summary, linear chain, tree, markdown, or JSON.
`ultrabrain_status`	Show session state, thought count, branches, and latest quality score.
`ultrabrain_history`	Return recent thought records.
`ultrabrain_export`	Export a session as markdown, text, or JSON.
`ultrabrain_metrics`	Return aggregate session and reasoning metrics.
`ultrabrain_templates`	List built-in LCV engineering reasoning templates.
`ultrabrain_reset`	Clear one session or all in-memory sessions.

MCP Configuration

Global npm installation target in the LCV Windows environment:

C:\npm-global\node_modules\@lcv-ideas-software\ultrabrain-mcp

Use the MCP server name ultrabrain in host configs:

{
  "mcpServers": {
    "ultrabrain": {
      "command": "ultrabrain-mcp",
      "args": []
    }
  }
}

Development checkout and global installation are intentionally separate. Do not create a junction or symlink from C:\npm-global\node_modules\@lcv-ideas-software\ultrabrain-mcp to the workspace checkout.

Optional local persistence can be enabled per host with ULTRABRAIN_STATE_DIR or ULTRABRAIN_PERSIST_DIR. When unset, sessions remain process-local.

Development

npm install
npm test
npm run format:public:check
npm pack --dry-run

The smoke test starts the built MCP server over stdio, lists tools, verifies the branded ultrabrain_* surface, exercises session start, thought, branch, merge, validation, status, export, prompts, and resources.

Release Automation

This repository follows the LCV package baseline:

CI runs on main pull requests and pushes.
Dependabot tracks npm and GitHub Actions updates.
Pages deploys the static site from site/ using ultrabrain-mcp.lcv.dev.
Auto-tagging derives padded public tags from package.json version.
Publish workflow releases to npmjs.com, GitHub Packages, and GitHub Releases.
StepSecurity Harden-Runner is enabled on workflows.

Research

See docs/research-matrix.md. Ultrabrain imports ideas only at the architecture level. It does not copy third-party code, text, branding, non-English localization strings, or external model/API behavior.
