cognigy-vibe-mcp 1.7.1rc2

Cognigy AI agent demo builder MCP server

cognigy-vibe-mcp

A local Python MCP server for building Cognigy AI agent demos with Claude Code. Covers the full Cognigy REST API surface — node creation, flow inspection, code push with conflict detection, session testing, and a 20-topic reference library.

Part of the cognigy-vibe repo — this package is the MCP server; the plugin repo also ships the Claude Code skills that drive it.

Installation

uv tool install cognigy-vibe-mcp                        # stable
uv tool install cognigy-vibe-mcp --prerelease allow     # latest RC prerelease
uvx cognigy-vibe-mcp==1.7.0rc1                          # specific RC (check PyPI for latest)

Setup CLI (cognigy-vibe-setup)

Installing this package also installs cognigy-vibe-setup, a CLI that manages the companion Claude Code plugin — marketplace entry, plugin install/uninstall, and the Claude Desktop config version pin. It's separate from the MCP server process itself.

cognigy-vibe-setup                 # install — default when no subcommand is given
cognigy-vibe-setup install         # explicit alias for the default
cognigy-vibe-setup status          # report drift across marketplace/plugin/Desktop pins; no changes
cognigy-vibe-setup status --fix    # same check, applies fixes; never touches PyPI or upgrades the package
cognigy-vibe-setup update          # check PyPI for a newer cognigy-vibe-mcp, upgrade if stale, then reconcile
cognigy-vibe-setup update --check  # dry-run of update — reports drift, changes nothing
cognigy-vibe-setup uninstall       # reverse install: plugin, Desktop config entry, optionally credentials

Flag	Applies to	Description
--install-only	install	Skip credential collection; install the plugin only.
--client code|desktop|both	install	Which client(s) to configure (default: both if Desktop is detected, else code).
--scope user|project|local	install	Plugin install scope for Claude Code (default: user).
--scope user|project|local	uninstall	Override the auto-detected plugin scope to uninstall from (default: auto-detected via claude plugin list).
--verbose	all subcommands	Stream subprocess output instead of hiding it behind a status line; show a full traceback instead of a short message on failure.

uninstall always prompts before deleting ~/.config/cognigy-vibe/.env — credentials are the one step that is never non-interactive, regardless of flags.

Quick start

Run cognigy:init-cognigy-vibe in Claude Code to capture your Cognigy credentials and build defaults. It writes .env at your workspace root and ~/.config/cognigy-vibe/config.json globally. No restart required.

If credentials aren't configured yet, the server starts in degraded mode — all tools are visible but every call returns setup guidance until you create a .env. Once the file exists, retry the same tool call and it executes immediately without restarting.

Once connected, call sync_remote_state to populate state from your Cognigy project.

Manual configuration

Add to .mcp.json at your project root:

{
  "mcpServers": {
    "cognigy-vibe": {
      "command": "uvx",
      "args": ["cognigy-vibe-mcp"]
    }
  }
}

Credentials are read from a .env file in the project root (see Environment variables below). If no .env exists, the server starts in degraded mode — all tools are visible but calls return setup guidance until credentials are configured.

Environment variables

Variable	Required	Default	Description
COGNIGY_BASE_URL	Yes	—	Cognigy API base URL (e.g. https://cognigy-api-au1.nicecxone.com)
COGNIGY_API_KEY	Yes	—	API key from Cognigy UI → My Profile → API Keys
COGNIGY_PROJECT_ID	No	—	Default project; can be set later via sync_remote_state
COGNIGY_VIBE_RESYNC_HOURS	No	4	Hours of idle before auto-resync
COGNIGY_VIBE_CACHE_TTL	No	300	Resource cache TTL in seconds
COGNIGY_VIBE_DEV	No	—	Set to 1 to enable dev mode (requires credentials configured)
COGNIGY_VIBE_SOURCE_DIR	No	—	Path to cognigy-vibe-mcp/ source tree; required when COGNIGY_VIBE_DEV=1. Relative paths are resolved from CWD (e.g. ./cognigy-vibe-mcp works when Claude Code opens the repo root).

Startup modes

The server selects a mode at startup based on the .env file in the project root:

Condition	Mode	Tools available
COGNIGY_BASE_URL or COGNIGY_API_KEY missing	Degraded	Full tool set (calls return setup guidance)
Both present, COGNIGY_VIBE_DEV absent	Production	Full tool set
Both present, COGNIGY_VIBE_DEV=1	Dev	Full tool set + reload_mcp

In degraded mode every tool call returns guidance on creating .env with the correct credentials. Once the file exists, retry the same call — the server restarts to production mode and returns the real response immediately.

Dev mode spawns the inner server from COGNIGY_VIBE_SOURCE_DIR via uv run. After editing source files, call reload_mcp to respawn from updated code in the same Claude session.

Tools

State & sync

cognigy_update	PATCH with always-fresh GET + optional deep merge
cognigy_delete	DELETE any resource including nodes
cognigy_invoke	Named operations: move, clone, train, inject, search
get_flow_chart	Chart with relations array + readable hierarchy string

push_html_node	Push local .html to a setHTMLAppState node
push_agent_tool	Create or update a file-backed aiAgentJobTool from a .tool.json

Testing

Tool	Description
talk_to_agent	Send a message to a flow via REST endpoint

Guidance

Tool	Description

explain topics

Call explain() for an overview. Call explain("topic") for full details.

node-positioning · node-wiring · agent-tool-branch · node-config-update · flow-chart-reading · tool-conditions · two-pass-confirm · turn-structure · xapp-delivery · cognigyScript · code-node-patterns · voice-gateway · outbound-trigger · knowledge-store · endpoint-config · function-execution · session-injection · extension-map · node-types · mcp-comparison

Topics are front-loaded in the tool description — no tool call needed to see what's available.

Key behaviours

• Extension auto-injection — cognigy_create injects extension for all known node types: @cognigy/voicegateway2 for setSessionConfig/hangup, cognigy-ai-agent for AI agent nodes, cxone-utils for xApp nodes
• Say node normalisation — config: { text: "Hello" } is automatically wrapped into the full config.say.text envelope
• Conflict detection — push_code_node snapshots the last-pushed content and blocks if the Cognigy UI has been edited since
• Auto-resync — sessions idle longer than the threshold are silently re-synced before the next tool call
• Atomic writes — state and cache files use write-to-tmp-then-replace to survive process interrupts
• Graceful degraded mode — server always starts; missing credentials surface the init tool instead of crashing

Development

git clone https://github.com/ben-elliot-nice/cognigy-vibe
cd cognigy-vibe/cognigy-vibe-mcp
uv sync --extra dev
uv run pytest tests/ -v

To develop against local source with hot-reload, the repo's .mcp.json already sets COGNIGY_VIBE_DEV=1 and COGNIGY_VIBE_SOURCE_DIR=./cognigy-vibe-mcp — no .env additions needed. Ask Claude to call reload_mcp after editing source files — the server respawns from updated code without a terminal restart.
