unblu-mcp

ci documentation pypi version python versions license FastMCP

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.

📚

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.

Development

git clone https://github.com/detailobsessed/unblu-mcp.git
