cognigy-vibe-mcp 1.4.0

Cognigy AI agent demo builder MCP server

cognigy-vibe-mcp

A local Python MCP server for building Cognigy AI agent demos with Claude Code. Provides 15 tools covering 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-claude-plugin.

Installation

uvx cognigy-vibe-mcp

Or install permanently:

uv tool install cognigy-vibe-mcp

Quick start

In your demo project directory, run the cognigy:init-mcp skill in Claude Code. It will:

1. Create ~/.config/cognigy-mcp/<project-id>/ for state and cache
2. Create a .cognigy-mcp symlink in your project root
3. Write the MCP server entry to .claude/mcp.json

Then restart Claude Code and call sync_remote_state to populate state from your Cognigy project.

Manual configuration

Add to .claude/mcp.json:

{
  "mcpServers": {
    "cognigy-vibe": {
      "command": "uvx",
      "args": ["cognigy-vibe-mcp"],
      "env": {
        "COGNIGY_BASE_URL": "https://cognigy-api-au1.nicecxone.com",
        "COGNIGY_API_KEY": "<your-api-key>",
        "COGNIGY_PROJECT_ID": "<your-project-id>"
      }
    }
  }
}

Environment variables

Variable	Required	Default	Description
COGNIGY_BASE_URL	Yes	—	Cognigy API base URL
COGNIGY_API_KEY	Yes	—	API key from Cognigy UI → My Profile → API Keys
COGNIGY_PROJECT_ID	No	—	Default project; prompted if omitted
COGNIGY_VIBE_RESYNC_HOURS	No	4	Hours of idle before auto-resync
COGNIGY_VIBE_CACHE_TTL	No	300	Resource cache TTL in seconds

Tools

State & sync

Tool	Description
sync_remote_state	Wipe cache and repopulate from Cognigy remote
get_build_state	Return name→ID mappings (filterable by resource_type)
resolve_resource	Fast name→ID lookup from local state (no API call)

Flow operations

Tool	Description
cognigy_get	GET any resource, cache-first
cognigy_list	List resources; singular/plural resource_type both accepted
cognigy_create	POST resource; extension auto-injected, Say config auto-normalised
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

File push

Tool	Description
push_code_node	Push local .js/.ts to a code node with conflict detection
push_html_node	Push local .html to a setHTMLAppState node

Testing

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

Guidance

Tool	Description
explain	20-topic reference library (see below)

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
