Hoofy MCP Server

Connect Hoofy to Claude, Cursor or any other MCP client and it stops being a tab you switch to. Your AI development companion. An MCP server that gives your AI persistent memory, structured specifications, and adaptive change management — so it builds what you actually want. The hoofy mcp server is what makes that connection.

What the server does

The AI coding assistant that remembers context and reduces spec hallucinations.

Hoofy solves three recurring AI-dev problems: memory loss between sessions, hallucinated implementations, and unstructured workflows. It's a single MCP (Model Context Protocol) server written in Go — one binary, zero external runtime dependencies.

• Principles-first pipeline — — define non-negotiables before requirements
• Clarity Gate — — blocks vague specs before implementation starts
• Context-check on every change — — catches conflicts early
• Spec-aware review/audit — — compare code against requirements and rules
• Persistent memory + knowledge graph — — decisions and fixes remain searchable
• Hot/cold instructions — — lightweight core instructions + on-demand guides

Installation

Setup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client.

Available tools

The toolset is worth reading before you wire it up, because it tells you what the integration is really for:

• Principles — first pipeline** — define non-negotiables before requirements
• Context — check on every change** — catches conflicts early
• Spec — aware review/audit** — compare code against requirements and rules
• Spec-vs — Code Audit** — sdd_audit compares specifications against source code to detect missing implementations and drift
• Auto — Generated Agent Instructions** — sdd_init_project injects SDD instructions into CLAUDE.md/AGENTS.md (idempotent)
• Facade — First Tooling** — unified memory entry points: mem_save and mem_session
• Pre — pipeline Exploration** — sdd_explore captures goals/constraints/unknowns before formal pipeline work
• Cursor — .cursor/rules/hoofy.md
• OpenCode — AGENTS.md
• Reviews — sdd_review
• Memory — mem_save, mem_session
• EARS — Research-backed sentence templates that eliminate requirements ambiguity

Worth knowing first

• It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
• With 14 tools registered it takes up a noticeable share of the context window; turn it off in projects that never touch Hoofy.
• Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.

Where it fits

Plenty of developer tooling servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Hoofy's toolset — Principles, Context, Spec and 11 more — is a fair guide to whether it matches your workflow.

We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.
