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. Stable. Current release: v01.02.01 (npm package 1.2.1). See CHANGELOG.md for the full release history.

First publication started at v01.00.00. Public GitHub tags use the LCV display convention v00.00.00; npm keeps normal SemVer.

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.

Canonical Example

{
  "thought": "Map the failure, list evidence, compare alternatives, and choose the next verification step.",
  "thought_number": 1,
  "total_thoughts": 4,
  "next_thought_needed": true,
  "mode": "hybrid",
  "step_type": "analysis",
  "evidence": ["The failing behavior was reproduced locally."],
  "alternatives": ["patch the caller", "patch the shared parser"],
  "risks": ["a shared parser change can affect unrelated hosts"],
  "next_actions": ["run the focused test", "inspect the shared call path"],
  "quality_metrics": {
    "logical_consistency": 4,
    "completeness": 4,
    "objectivity": 4,
    "practicality": 5,

  },
  "response_format": "json"
}

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.
