Your AI finally remembers.

You explain your codebase to Claude. Architecture, constraints, patterns. Then you hit the context limit. New session. Claude forgets everything.

You: "Our auth uses JWT..."       You: /catchup

         ↓                         What should we work on?"
    [Memory]  ────────────────►

Persistent, project-scoped memory with semantic search. Conventions, decisions, snippets — stored locally, never forgotten.

Option A: Automated with hive-mcp-cli (Recommended)

# Requires Go 1.21+
go install github.com/hive-agi/hive-mcp-cli/cmd/hive@latest
go install github.com/hive-agi/hive-mcp-cli/cmd/hive-setup-mcp@latest

# Register and let Claude guide setup
claude mcp add hive-setup --scope user -- hive-setup-mcp
claude
# Ask: "Help me setup hive-mcp"

Option B: Manual

export HIVE_MCP_DIR="$HOME/hive-mcp"
export BB_MCP_DIR="$HOME/bb-mcp"

git clone https://github.com/hive-agi/hive-mcp.git "$HIVE_MCP_DIR"
git clone https://github.com/hive-agi/bb-mcp.git "$BB_MCP_DIR"

claude mcp add hive --scope user -- "$HIVE_MCP_DIR/start-bb-mcp.sh"

claude mcp list | grep -q "hive" && echo "OK" || echo "FAILED"

ollama pull nomic-embed-text      # Local embeddings
docker compose up -d              # Chroma vector DB

Optional:

• Emacs 28.1+ for swarm vterm UI and buffer integration. See Emacs Configuration.
• Headless mode works without Emacs (but WIP for stability of headless - recommended to use Emacs as a dependency).

Each tool is a consolidated namespace with subcommands (e.g., memory add, memory query, kg traverse).

hive-mcp uses a plugin architecture based on the IAddon protocol with automatic classpath discovery. Creating a new addon takes one command:

clojure -Sdeps '{:deps {io.github.hive-agi/hive-mcp {:git/tag "vX.Y.Z" :git/sha "..."}}}' \
  -Tnew create :template hive-agi/addon :name com.example/my-addon

This generates a complete project with:

• IAddon protocol implementation (defrecord with 8 lifecycle methods)
• META-INF classpath manifest (auto-discovered at startup, zero core changes)
• Unit tests (12 tests covering lifecycle, tools, health)
• REPL-ready development setup

Addons are discovered via META-INF/hive-addons/*.edn manifest files on the classpath (same pattern as Java's ServiceLoader). Manifests declare dependencies, and addons are loaded in topological order. No changes to hive-mcp core code needed.

See the Creating Addons wiki guide and ADR-0007 for architecture details.

See CLAUDE.md for project conventions, tool patterns, and memory usage guidelines.
