unblu-mcp

A Model Context Protocol (MCP) server for debugging and operating Unblu deployments. Optimised for debugging workflows — curated typed tools for common operations, plus an escape hatch for the full 300+ endpoint API.

📚 Full Documentation

Design

The server exposes three layers, each progressively more powerful:

Layer	What it is	When to use
Curated tools	Typed, token-efficient tools for common debugging tasks	90% of debugging sessions
execute_operation	Generic escape hatch for any of 331 Unblu API operations	When a curated tool doesn't exist
Resources	Read-only api:// URIs for browsing the API surface	Discovery and schema inspection

Quick Start

Installation

uvx unblu-mcp

Or install persistently: uv tool install unblu-mcp

MCP Client Configuration

Direct API access with an API key:

{
  "mcpServers": {
    "unblu": {
      "command": "uvx",
      "args": ["unblu-mcp"],
      "env": {
        "UNBLU_BASE_URL": "https://your-instance.unblu.cloud/app/rest/v4",
        "UNBLU_API_KEY": "your-api-key"
      }
    }
  }
}

Kubernetes port-forward (auto-managed):

{
  "mcpServers": {
    "unblu": {
      "command": "uvx",
      "args": ["unblu-mcp", "--provider", "k8s", "--environment", "dev"],
      "env": {
        "PATH": "/Users/YOUR_USERNAME/.local/bin:/opt/homebrew/bin:/usr/local/bin:/usr/bin:/bin"
      }
    }
  }
}

Tools

Curated tools (read-only)

Tool	Description
get_current_account	Current account info — good first call to verify connectivity
search_conversations(status?, topic?, assignee_id?, limit?, fields?)	Search conversations with filters
get_conversation(conversation_id)	Full conversation detail with participants
search_persons(query?, email?, limit?, fields?)	Find persons (visitors, agents)
get_person(person_id)	Full person detail
get_persons(identifiers, fields?)	Batch-resolve up to 20 persons in parallel
search_users(query?, email?, limit?, fields?)	Find registered users
get_user(user_id)	Full user detail
check_agent_availability(named_area_id?)	Check agent availability per named area
search_named_areas(query?, limit?)	List named areas (routing targets)
find_operation(query, service?, include_schema?, limit?)	Discover API operations by keyword

Mutation tools

Tool	Description
assign_conversation(conversation_id, agent_id)	Assign a conversation to an agent
end_conversation(conversation_id)	End an active conversation

Escape hatch

Tool	Description
execute_operation(operation_id, path_params?, query_params?, body?, fields?, confirm_destructive?)	Execute any of the 331 Unblu API operations

Resources

URI	Description
api://services	JSON list of all API service groups
api://operations/{operation_id}	Full resolved schema for a specific operation

Prompts

Prompt	Description
debug_conversation(conversation_id)	Step-by-step debugging workflow for a conversation
find_agent(criteria)	Locate an agent and check their availability
account_health_check	Validate account configuration and connectivity

Safety

By default, execute_operation blocks DELETE operations unless confirm_destructive=True is passed. For stricter control, install the optional Eunomia policy engine:

uv tool install "unblu-mcp[safety]"

Then point to a policy file:

{
  "mcpServers": {
    "unblu": {
      "command": "unblu-mcp",
      "args": ["--policy", "config/mcp_policies.json"],
      "env": { "UNBLU_BASE_URL": "...", "UNBLU_API_KEY": "..." }
    }
  }
}

The bundled config/mcp_policies.json allows all read-only and curated tools while blocking destructive execute_operation calls by operation ID pattern.
