Roadmap & Status

Completed

  • [x] Rust Daemon: Topic Pub/Sub and Service Req/Res message routing.
  • [x] Python SDK (Simple API): Node class with connect, publish, subscribe, service, call_service, spin.
  • [x] Python SDK Dual-Layer API: LifecycleNode with on_configure/on_activate/on_deactivate/on_shutdown.
  • [x] ~~MCP Bridge (Rust)~~: Removed in v0.3.0 — superseded by mcp-gateway (Python Gateway Node with transport-level relay).
  • [x] ~~MCP Transport Layer~~: Removed in python-sdk-mcp v0.2.0 — replaced by direct Streamable HTTP connections.
  • [x] MCPServerNode Base Class: python-sdk-mcp v0.2.0 — base class for MCP Server Nodes with auto Streamable HTTP + /mcp/directory publishing.
  • [x] MCP Gateway: mcp-gateway v0.1.0 — transport-level stdio→HTTP relay + directory service.
  • [x] Tagentacle MCP Server: Built-in MCP Server exposing bus interaction tools (FastMCP-based, auto-schema from type hints).
  • [x] tagentacle.toml Spec: Define and parse package manifest format.
  • [x] Bringup Configuration Center: Config-driven topology orchestration with parameter injection.
  • [x] CLI Toolchain: daemon, run, launch, topic echo, service call, doctor, setup dep, setup clean.
  • [x] Environment Management: uv-based per-package .venv isolation, workspace install/ structure with symlinks.
  • [x] Secrets Management: secrets.toml auto-loading, bringup environment variable injection.
  • [x] SDK Utilities: load_pkg_toml, discover_packages, find_workspace_root.
  • [x] Workspace Repo Auto-Clone: [workspace.repos] in bringup tagentacle.toml — setup dep --all auto-clones missing git repos.
  • [x] Example Packages: example-agent, example-mcp-server, example-bringup as independent repos.
  • [x] TACL (Tagentacle Access Control Layer): python-sdk-mcp v0.3.0 — MCP-level JWT authentication with auth_required on MCPServerNode, AuthMCPClient, PermissionMCPServerNode (SQLite agent registry + credential issuer).
  • [x] Standard System Services: Daemon-intercepted /tagentacle/ping, /tagentacle/list_nodes, /tagentacle/list_topics, /tagentacle/list_services, /tagentacle/get_node_info.
  • [x] Node Registration & Heartbeat: Register handshake, periodic ping/pong, automatic stale-node cleanup (90s timeout).
  • [x] Node Disconnect Cleanup: Automatic removal of subscriptions, services, and node entries on disconnect, with /tagentacle/node_events publishing.
  • [x] JSON Schema Validation: python-sdk-core v0.3.0 — SchemaRegistry with auto-discovery from interface packages, configurable per-node (strict/warn/off), integrated into Node.publish() and Node._dispatch(). Requires optional jsonschema>=4.0.
  • [x] TACL space Claim: python-sdk-mcp v0.4.0 — JWT space field binding agents to isolated execution environments. Full stack: CallerIdentity.space, sign_credential(space=...), PermissionMCPServerNode.register_agent(space=...).
  • [x] Container Orchestration Pkg: container-orchestrator v0.1.0 — LifecycleNode managing Docker containers via bus services (/containers/create, stop, list, exec, etc.).
  • [x] Shell Server Pkg: shell-server v0.1.0 — MCPServerNode exposing exec_command tool with TACL space-aware dynamic container routing (JWT → container → local fallback).

Planned

  • [ ] Standard Topics (SDK-side): SDK auto-publish to /tagentacle/log, /tagentacle/diagnostics.
  • [ ] SDK Log Integration: Auto-publish node logs to /tagentacle/log via get_logger().
  • [ ] Flattened Topic Tools API: SDK API to auto-generate flattened MCP tools from Topic JSON Schema definitions (e.g., a registered /chat/input schema auto-generates a publish_chat_input(text, sender) tool with expanded parameters).
  • [ ] Interface Package: Cross-node JSON Schema contract definition packages.
  • [ ] Action Mode: Long-running async tasks with progress feedback.
  • [ ] Parameter Server: Global parameter store with /tagentacle/parameter_events notifications.
  • [ ] Web Dashboard: Real-time topology, message flow, and node status visualizer.
