MindSync AI

One orchestrator. Your coding agents. Shared context.

MindSync AI is a local-first MCP orchestration layer for coding agents. It turns the CLI already working with you into the lead orchestrator: MindSync discovers available workers, routes tasks by capability, supervises execution, and keeps every session aligned through shared focus, events, and durable memory.

Use Codex, Claude, Antigravity/Gemini, Grok, Cursor, and Aider as one coordinated system—without introducing another hosted control plane. MindSync works locally by default, requires no MindSync account, and makes remote synchronization entirely optional.

Why MindSync?

Running several capable agents is easy. Keeping them coordinated is the hard part. Without a shared layer, agents duplicate work, overwrite files, lose decisions between sessions, and force the user to manually choose a worker for every task.

MindSync provides:

• Automatic orchestration — the human-facing CLI decides when delegation is useful.

• Capability-based routing — workers are ranked by task fit, availability, and priority.

• Conflict prevention — active file and project focus is visible before work begins.

• Shared local memory — session state, events, and queued facts survive restarts.

• Safe process control — tracked jobs, timeouts, cancellation, and process-tree cleanup.

• Optional durable sync — important facts can be shared through your own SSH host.

• Explainable decisions — every automatic route includes the reason and candidate scores.

The orchestrator remains responsible for planning, authorization, integration, and the final answer. Delegated workers receive bounded tasks and cannot recursively delegate through MindSync.

Quick start

Install MindSync:

pip install mindsync-ai

Run one-time onboarding:

mindsync setup --mode auto
mindsync doctor

Restart the configured CLI sessions. From then on, the CLI can use MindSync automatically; the user does not need to name a worker for every task.

setup is idempotent. Existing MCP registrations are preserved unless --force is explicitly supplied, and a non-mutating preview is available:

mindsync setup --dry-run

Requires Python 3.10 or newer.

Install from source

git clone https://github.com/adityarya24/mindsync-ai.git
cd mindsync-ai
python -m pip install -e ".[dev]"

Supported clients and workers

MindSync distinguishes an MCP host from a worker backend. A CLI may support one or both roles.

Antigravity and Gemini CLI are two execution backends in one logical gemini-antigravity family—not two separate logical agents. When either backend is the human-facing orchestrator, MindSync excludes both from automatic worker selection to prevent self-delegation.

Detected clients without a supported registration surface are reported but never modified through guessed or undocumented configuration.

Automatic orchestration

Static roles remain supported, but they are optional. Omitting agent from delegate_task is equivalent to agent="auto".

delegate_task(
  prompt="Audit authentication and report concrete vulnerabilities",
  required_capabilities=["security", "review"]
)

The router:

1. infers capabilities when none are supplied;

2. filters out missing CLIs and explicit exclusions;

3. excludes the human-facing agent family;

4. ranks eligible workers using capability weights and routing priority;

5. stores and returns the complete routing explanation.

Use route_task to preview a decision and list_agents to inspect the live worker inventory.

Orchestration modes

Policy is stored in ~/.mindsync/orchestration.json.

Manage policy from the CLI:

mindsync config
mindsync config orchestration.mode suggest
mindsync config orchestration.announce false
mindsync config orchestration.maxParallel 4

The default parallel limit is three automatically routed pending or running jobs. MindSync never retries a failed write-capable task on another worker automatically, preventing duplicate edits.

Custom workers

Add custom adapters to ~/.claude/agent-dispatch/agents.json:

{
  "agents": [
    {
      "name": "my-worker",
      "family": "my-provider-family",
      "bin": "my-cli",
      "input": "stdin",
      "capabilities": ["general", "coding", "testing"],
      "capabilityWeights": {"coding": 100, "testing": 90},
      "routingPriority": 75
    }
  ]
}

Authentication remains the responsibility of each worker CLI.

Shared context and coordination

MindSync combines three coordination layers:

A typical session uses:

1. get_sync_context(agent_name) to load current state and compiled truth.

2. update_focus(...) before editing to detect overlapping work.

3. delegate_task(...) for bounded work that benefits from another agent.

4. queue_durable_fact(...) for high-confidence decisions worth retaining.

5. sync_offline_facts(...) when an optional remote store comes back online.

MCP tools

MindSync exposes 20 tools.

Memory and focus

Event bus

Dispatch and orchestration

Background completion ping

After delegate_task(..., background=True) returns a job ID, call job_wait(job_id) immediately. The MCP call remains pending while the worker runs and returns a completion ping with the mechanical review when the job reaches done, failed, or cancelled. This keeps the orchestrator's turn alive and removes the need for the user to ask for repeated status checks. If a job exceeds the wait timeout, call job_wait again to continue watching it.

MCP servers cannot reopen a chat turn after the client has closed it, so the orchestrator must start job_wait before ending its response.

Dispatch CLI

mindsync-dispatch agents
mindsync-dispatch models <agent>
mindsync-dispatch roles
mindsync-dispatch run auto "implement and test the fix" \
  --capability coding --capability testing
mindsync-dispatch run codex "summarize README" \
  --worktree --effort high --check "pytest -q"
mindsync-dispatch status
mindsync-dispatch review <job-id>
mindsync-dispatch result <job-id>
mindsync-dispatch cancel <job-id>

Jobs live under ~/.claude/agent-dispatch/jobs/; override this with AGENT_DISPATCH_HOME.

--worktree provides advisory isolation. Agents still run with the permissions of the current user, so task wording and working-directory boundaries must agree.

Manual MCP configuration

If native setup is unavailable, register the server manually:

{
  "mcpServers": {
    "mindsync": {
      "command": "python",
      "args": ["-m", "mindsync.server"]
    }
  }
}

On Windows, use the full path to the appropriate python.exe when client processes do not share the same PATH.

Optional remote synchronization

Core coordination works without a network connection. To share durable facts through an always-on host, configure:

export MINDSYNC_SSH_HOST=my-server
export MINDSYNC_REMOTE_ROOT=/opt/mindsync

SSH must support non-interactive key authentication. See .env.example and examples/remote/.

For a VPS + laptop setup:

1. deploy the scripts from examples/remote/ on the VPS;

2. point the laptop at that host with the two variables above;

3. for sync-only use, leave remote variables empty on the VPS itself; remote dispatch submitters set only MINDSYNC_REMOTE_ROOT so they write into that local durable store.

Remote Dispatch Queue & Worker

MindSync enables a remote orchestrator (e.g., running on a VPS) to submit work into a queue on the remote store, which a worker running on the local machine claims and executes within its own interactive session.

Submitting a job (remote side)

On the VPS, point only MINDSYNC_REMOTE_ROOT at the existing local durable-store root; no SSH host is needed because the queue is local there.

export MINDSYNC_REMOTE_ROOT=/opt/mindsync
mindsync submit --repo /path/to/repo --prompt "implement feature" --agent codex
mindsync status <job-id>

Remote jobs default to the safe worker execution mode. To run a configured human-facing CLI as an orchestrator, opt in explicitly and name the agent (or role) in the payload:

mindsync submit --repo /path/to/repo --prompt "plan and implement feature" \
  --execution-mode orchestrator --agent <configured-orchestrator-agent>

Or use a configured role instead: --execution-mode orchestrator --role <configured-role>. Orchestrator submissions without an explicit --agent or --role are rejected.

An orchestrator job is accepted only when the local worker owner also enables the boundary with MINDSYNC_WORKER_ALLOW_ORCHESTRATOR=true (or the one-shot mindsync worker --once --allow-orchestrator / loop --allow-orchestrator flag). The remote repository allow-list, branch check, write sandbox, and result lifecycle apply in both modes. The orchestrator process is allowed to use MindSync delegation; every child dispatch remains a depth-1 worker with MINDSYNC_WORKER=1 and cannot delegate recursively. Legacy payloads without the mode/depth fields remain worker jobs.

Running the worker (local side)

Configure worker environment:

$env:MINDSYNC_SSH_HOST = "mindsync-vps"
$env:MINDSYNC_REMOTE_ROOT = "/opt/mindsync"
$env:MINDSYNC_WORKER_ALLOWED_ROOTS = "C:\work\project1;C:\work\project2"
# Optional, privileged local opt-in for explicit orchestrator payloads:
$env:MINDSYNC_WORKER_ALLOW_ORCHESTRATOR = "true"

Keep a non-default SSH port in the selected host's ~/.ssh/config entry (this setup uses port 2422); MindSync intentionally has no separate port setting.

Start the worker loop:

mindsync worker

Or process at most one job and exit:

mindsync worker --once

Configuration

Local data

By default, state is stored under ~/.mindsync:

~/.mindsync/
├── local-state.json       active project and per-agent focus
├── local-audit.jsonl      append-only action audit
├── offline_queue.jsonl    durable facts waiting for remote sync
├── events.jsonl           event bus
├── events.jsonl.seq       monotonic sequence checkpoint
├── subscriptions.json     event subscriptions
├── orchestration.json     automatic delegation policy
├── compiled-truth/        pulled durable summaries
└── .locks/                kernel-managed lock files

Safety model

• The human-facing CLI owns authorization, integration, and the final answer.

• Delegated workers cannot recursively delegate through MindSync.

• Automatic routing never expands the permissions granted by the user.

• Setup preserves existing registrations and supports a non-mutating dry run.

• Cursor configuration is merged atomically and backed up before forced replacement.

• Local state uses crash-safe OS locks and atomic file replacement.

• Remote identifiers are allowlisted; text is encoded safely before SSH transfer.

• Pulled truth is treated as untrusted and validated before replacing local files.

• Job cancellation terminates the spawned process tree.

MindSync runs with the privileges of the current user. Connect only trusted local agents. See SECURITY.md for the complete security policy.
