Memorix MCP Server

---

Memorix gives the AI coding agents you already use a shared, searchable project memory that survives new chats, IDE switches, terminal sessions, and handoffs. The memory lives under the Git project, not inside one chat window or one tool.

Use Claude Code today, Codex tomorrow, and Cursor in the afternoon. The agent can change; the project memory stays the same.

Use Memorix when you keep re-explaining the same project to a new agent session: the last session already figured something out, another IDE cannot see it, or a design decision is buried in a chat you cannot find anymore.

Memorix is local-first. SQLite is the canonical store, Orama handles search, and LLM-backed formation/embedding is optional. Without model keys, Memorix still works with local full-text retrieval.

Capabilities

Memorix is more than a memory store. It also installs agent integrations, keeps useful work events, turns commits into project facts, exposes a local control plane, and can coordinate multi-agent work when a task needs it.

Memorix connects through the interfaces each agent already supports: plugin packages, MCP, project rules, hooks, skills, or the bundled terminal agent. memorix setup chooses the right setup for each agent and keeps stdio MCP as the default transport.

Integration surfaces:

See Integration Surfaces for the current support matrix and what each generated file means.

Use the same setup command without --global only when you intentionally want repo-local guidance, rules, or hooks in the current Git project.

CLI, MCP, and HTTP are different entry points:

• memorix CLI is the direct command surface for setup, memory search/store, Git Memory, import/export, dashboard, orchestration, diagnostics, and automation.
• memorix serve is the stdio MCP bridge used by IDEs and coding agents. Its default tool profile is micro, so agents see only the compact core tool set.
• memorix background start / memorix serve-http run the HTTP service for a shared endpoint, dashboard, Docker, or multiple clients.

Requirements:

• Node.js >=22.18.0
• Git, because project identity is derived from the real Git root

Install and initialize:

npm install -g memorix
memorix init --global                   # optional defaults
memorix setup --agent claude --global   # or codex, copilot, cursor, pi, gemini-cli, opencode,
                                       # windsurf, kiro, antigravity, trae, openclaw, hermes, omp

memorix init is optional. It creates or updates TOML configuration:

• ~/.memorix/config.toml for global defaults
• <git-root>/memorix.toml for optional project overrides

Legacy memorix.yml, .env, and ~/.memorix/config.json are still read for compatibility, but new setup flows use TOML.

If you want repo-local guidance or hooks for a specific repository, run the same setup command from inside that repo without --global. Codex is the exception: its supported path is the user-level plugin install, so Memorix leaves project .codex configuration alone.

Connect an existing agent

Use the setup command first. The global form is the normal one-time install:

memorix setup --agent claude --global
memorix setup --agent codex --global
memorix setup --agent copilot --global
memorix setup --agent cursor --global
memorix setup --agent pi --global
memorix setup --agent gemini-cli --global
memorix setup --agent opencode --global
memorix setup --agent windsurf --global
memorix setup --agent kiro --global
memorix setup --agent antigravity --global
memorix setup --agent trae --global
memorix setup --agent openclaw --global
memorix setup --agent hermes --global
memorix setup --agent omp --global

What it installs depends on the target agent, but the goal is the same: make Memorix available wherever you open that agent without asking you to wire every repo by hand.

• Claude Code: installs the Memorix plugin package, adds CLAUDE.md guidance, and enables hook capture when you do not pass --noHooks.
• Codex: installs one user-level Memorix plugin with bundled stdio MCP, skills, and lifecycle hooks. It does not write project-local .codex config or change your model, approval, or sandbox settings. When Codex asks, review the plugin hook definition once with /hooks; --noHooks skips automatic capture.
• GitHub Copilot CLI: installs the Copilot plugin package and official Memorix skills.
• Pi: installs the user-level Pi package and official skills.
• Cursor: writes Cursor MCP/rules/config entries in the chosen scope.
• Gemini CLI: installs the extension package, GEMINI.md context, hooks, and skills. Antigravity CLI has an official Gemini CLI migration path, but Gemini CLI remains an active standalone target.
• OpenCode: installs the local plugin file, opencode.json, skills, and AGENTS.md guidance.
• Windsurf, Kiro, Trae: write the MCP/rules/hooks files the target supports.
• Antigravity: installs the official plugin package with plugin.json, mcp_config.json, hooks.json, rules, and skills under ~/.gemini/config/plugins/memorix or .agents/plugins/memorix.
• OpenClaw: installs an OpenClaw-compatible bundle with .mcp.json, official skills, and an OpenClaw HOOK.md/handler.ts hook pack.
• Hermes Agent: installs into Hermes home (%LOCALAPPDATA%\hermes on native Windows, ~/.hermes elsewhere, or HERMES_HOME), enables the plugin in config.yaml, registers plugin hooks, slash/CLI commands, skills, and writes MCP config.
• Oh-my-Pi: installs an omp.extensions package with extension hook events, a memorix command, official skills, and writes MCP config.

Need a quieter install? Add --noHooks for targets where setup can control hook capture separately from the host's official package entry. It keeps MCP and guidance, but skips Memorix hook capture.

If you intentionally want repo-local guidance or hooks, run the same command inside that repository without --global.

If your agent only needs a manual MCP entry, use stdio:

{
  "mcpServers": {
    "memorix": {
      "command": "memorix",
      "args": ["serve"]
    }
  }
}

For a manually managed Claude Code entry, add "alwaysLoad": true inside the memorix server object. This lets Claude Code expose Memorix tools during print-mode startup; memorix doctor agents --agent claude can detect and repair a missing setting.

HTTP is not required for normal setup. Use it only when you intentionally want a shared background service, dashboard, Docker, or multiple clients using the same endpoint:

memorix background start

Then point the client at:

http://localhost:3211/mcp

In HTTP mode, agents should bind the active repo explicitly with memorix_session_start(projectRoot=...) when the client can provide the workspace path. Git remains the final source of truth for project identity.

Uninstall

Preview what will be removed:

memorix uninstall --dry-run

Stop the background service and remove hooks:

memorix uninstall --background --hooks

Full cleanup:

memorix uninstall --yes --background --hooks --purge-data
npm uninstall -g memorix

memorix uninstall reports MCP config entries for manual cleanup instead of silently editing every MCP file it finds.

Work from the CLI

memorix --cwd /path/to/repo resume "continue release blocker"
memorix checkpoint list
memorix memory search --query "release blocker"
memorix memory --help

# Optional: activate one local agent identity for personal/team records and coordination.
memorix identity join --agent-type codex --name codex-main
memorix memory store --text "private investigation note" --visibility personal
memorix task create --description "verify the release package"

memorix transfer export --format json --out ./.memorix-export.json
memorix transfer import --file ./.memorix-export.json
memorix reasoning search --query "why sqlite"
memorix git-hook --force
memorix ingest log --count 20
memorix workbench

The CLI is direct and does not depend on an MCP session. It binds to the current Git project, or to the project supplied with --cwd. Without an active identity it reads, writes, and exports project-visible memory only. Use memorix identity join or memorix identity use --agent-id <id> only when you intentionally need personal/team memory or coordinated task actions; memorix identity clear returns the terminal to project scope. --as <active-agent-id> is the one-command alternative for scripts. Both camelCase and kebab-case flags are accepted.

Use the bundled terminal agent

memorix
# or
memcode

This opens memcode, a terminal coding agent that uses the same Memorix project memory as your MCP-connected agents.

Search is project-scoped by default. scope="global" searches across projects. The search boosts Git Memory for "what changed" questions and reasoning records for "why" questions.

memorix context "..." is the default Memory Autopilot entry. It builds a compact task-lensed brief for agents: bugfix tasks lean toward tests and repros, release tasks lean toward package/changelog/build checks, onboarding tasks lean toward docs and entry points, and stale or unrelated memories stay in warning lanes instead of flooding the prompt. A normal new task does not receive an old-session dump. For an explicit continuation, memorix resume "..." adds only the latest useful session summary, up to three readable durable anchors, and at most one recent source-labelled host compact checkpoint. A checkpoint is lifecycle evidence, not durable memory or a transcript backup. Agents should read the suggested files before trusting stored memory.

memorix serve defaults to --mode micro (7 tools) to keep MCP tool schemas small for agents. Use --mode lite for the extended solo memory surface, --mode team for coordination tools, or --mode full for advanced and compatibility tools such as checkpoint inspection.

memorix orchestrate uses the current checkout for single-worker runs. When running multiple workers, it creates task worktrees under .worktrees/ and merges successful task branches back. Use --isolated to force worktree isolation for one worker, --no-worktree to disable it, --allow-dirty to run with uncommitted changes, and --no-auto-merge to preserve task worktrees for manual review.

memcode is the terminal coding agent bundled with Memorix. It can read, edit, run commands, resume sessions, switch models, and use /memory commands — all backed by the same project memory as your MCP-connected agents.

Use it when you want a terminal agent with memory already wired in.

one Git project -> one shared Memorix memory pool

See docs/MEMCODE.md for the memcode-specific guide.

Minimal ~/.memorix/config.toml:

[agent]
provider = "openai"
model = "gpt-4o"
api_key = "..."

[memory.llm]
provider = "openai"
model = "gpt-4o-mini"
api_key = "..."

[embedding]
provider = "auto"

[memory]
inject = "minimal"
formation = "active"

Use [memory.llm] and [embedding] for Memorix memory quality and retrieval. Use [agent] for the model memcode talks to while coding. Keep credentials in global config or environment variables, and do not commit secrets.

For OpenRouter embeddings, use provider = "api", base_url = "https://openrouter.ai/api/v1", and model = "qwen/qwen3-embedding-8b". Memorix accepts OPENROUTER_API_KEY for that embedding endpoint; MEMORIX_EMBEDDING_API_KEY remains the explicit override.

Docker is for the HTTP service, not stdio MCP:

docker compose up --build -d

Then open:

• dashboard: http://localhost:3211
• MCP: http://localhost:3211/mcp
• health: http://localhost:3211/health

The container must be able to access the repository path passed as projectRoot for project-scoped Git and config behavior.

Use Memorix directly from TypeScript:

import { createMemoryClient } from 'memorix/sdk';

const client = await createMemoryClient({ projectRoot: '/path/to/repo' });

await client.store({
  entityName: 'auth-module',
  type: 'decision',
  title: 'Use JWT for API auth',
  narrative: 'Chose JWT because the API is stateless and used by multiple clients.',
});

const results = await client.search({ query: 'auth decision' });
await client.close();

LLM-friendly summaries: llms.txt and llms-full.txt.

Memorix draws from the MCP ecosystem and prior memory projects such as mcp-memory-service, MemCP, claude-mem, and Mem0. memcode is based on the Pi coding-agent codebase and adapts its terminal-agent model for the Memorix ecosystem.
