UltraBrain MCP Server

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.

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.
