ClickSend Communication Gateway Server
This Model Context Protocol (MCP) endpoint functions as a bridge, offering transactional SMS transmission and Text-to-Speech (TTS) voice interaction services by interfacing with the ClickSend platform's Application Programming Interface (API). It enables artificial intelligence entities to issue textual messages and trigger audible communications on demand.
Core Capabilities
- Short Message Service (SMS) Delivery: Transmit text messages to any global telephone receiver.
- Automated Voice Interaction: Execute voice calls incorporating messages synthesized from provided text.
- Traffic Control: Integrated mechanism imposing a constraint of five (5) operations per sixty-second interval.
- Data Integrity Checks: Rigorous verification protocols applied to recipient numbers and message payloads.
- Fault Reporting: Comprehensive error notifications and systematic error cascade management.
Deployment Guide
Prerequisites
- A runtime environment supporting Node.js (version 16 or newer).
- Active registration with ClickSend, securing necessary API authentication tokens.
- A compatible MCP Client application.
Initialization Sequence
-
Obtain the source code repository: bash git clone https://github.com/J-Gal02/clicksend-mcp.git cd clicksend-mcp
-
Install required dependencies: bash npm install
-
Compile the source code: bash npm run build
Configuring the MCP Client Integration
Incorporate the following configuration block into your cline_mcp_settings.json or claude_desktop_config.json file.
Ensure the path specified in args points accurately to the compiled JavaScript file within your build directory, alongside the substitution of placeholder credentials for your actual ClickSend username and secret key.
{ "mcpServers": { "clicksend": { "command": "node", "args": ["/path/to/build/directory/clicksend-mcp/build/index.js"], "env": { "CLICKSEND_USERNAME": "your_registered_email@example.com", "CLICKSEND_API_KEY": "YOUR_SECRET_API_KEY_HERE" } } } }
Operational Instructions
Exposed Functions
1. transmit_sms
For dispatching short text communications to designated numbers.
Arguments Schema:
- recipient_number: Destination telephone identifier, adhering to E.164 format (e.g., +447700900123).
- text_payload: The textual content intended for delivery.
Invocation Example:
{ "name": "transmit_sms", "arguments": { "recipient_number": "+447700900123", "text_payload": "Greetings from the ClickSend communication module!" } }
2. initiate_tts_call
To commence an automated voice call where the message is rendered audibly.
Arguments Schema:
- recipient_number: The target telephone identifier (E.164 format).
- spoken_content: The string data to be converted into synthesized speech.
- vocal_profile: Specification for the voice timbre ('female' or 'male', defaulting to 'female').
Invocation Example:
{ "name": "initiate_tts_call", "arguments": { "recipient_number": "+447700900123", "spoken_content": "This transmission is an automated voice message originating from ClickSend.", "vocal_profile": "male" } }
Throttling Mechanism
Operation is regulated by a rate constraint of five service requests per minute to mitigate unauthorized usage. Exceeding this threshold will result in an error response detailing the necessary wait duration before retrying.
Development Contributions
Available Execution Scripts
npm run build: Compiles TypeScript source into executable JavaScript artifacts.npm run start: Launches the MCP server process.npm run dev: Initiates the TypeScript compiler in continuous monitoring mode.

Exception Handling Protocols
The server furnishes granular diagnostic feedback across several potential failure vectors:
- Misformatted telephone numbers.
- Violations in message content constraints.
- Rate limitation threshold breaches.
- Issues related to API credential verification.
- Problems stemming from network instability.
Error messages delivered will include relevant status codes and unambiguous textual descriptions to facilitate rapid problem resolution.

WIKIPEDIA: Organizational management apparatus encompasses the array of systems, software constructs, regulatory mechanisms, computational frameworks, and established procedures utilized by enterprises to navigate evolving market dynamics, sustain competitive advantage, and enhance overall operational efficacy. == Conceptual Framework == Tooling can be categorized based on organizational function or departmental focus, such as tools for strategic foresight, workflow management, record-keeping, personnel administration, judgment support, oversight, etc. A functional breakdown often includes:
Mechanisms for data intake and correctness verification across all units. Instrumentation designed for monitoring and refining core operational flows. Systems dedicated to aggregating information and facilitating high-level decision-making. Contemporary business instrumentation has experienced explosive transformation in the last decade, propelled by rapid technological progress, creating a challenge in selecting optimal solutions for diverse corporate environments. This complexity arises from the perpetual drive to minimize expenditure and maximize revenue, coupled with the necessity to deeply comprehend customer requirements and deliver products precisely as demanded. Within this context, leadership should adopt a deliberate, strategic posture regarding business tools, rather than simply adopting the newest available technology. Over-reliance on off-the-shelf solutions without tailoring them often results in organizational friction. Selection of management tools requires careful calibration to align with, rather than dictate, the organization's specific operational needs.
== Prominent Instruments (2013 Benchmark) == A 2013 survey by Bain & Company illustrated the global adoption profile of business instruments, reflecting regional necessities shaped by economic conditions. The leading ten observed categories included:
Strategic Roadmapping Client Relationship Management (CRM) Personnel Sentiment Assessment Comparative Performance Analysis (Benchmarking) Performance Measurement Frameworks (Balanced Scorecard) Identification of Key Strengths (Core Competency) Operational Outsourcing Strategies Frameworks for Managing Organizational Transition Logistics Network Management (Supply Chain) Declarations of Purpose and Vision Customer Group Identification (Market Segmentation) Comprehensive Quality Assurance Methodologies (TQM)
== Enterprise Software Applications == Software collections deployed by business personnel to execute diverse corporate functions are termed 'business software' or 'business applications.' These applications aim to elevate productivity, quantify performance metrics, and execute various enterprise tasks with precision. The evolution progressed from early Management Information Systems (MIS) to comprehensive Enterprise Resource Planning (ERP) suites, later incorporating CRM capabilities, culminating in the current paradigm of cloud-based business management solutions. While a measurable correlation exists between Information Technology investment and organizational outcomes, two factors are paramount for value realization: the efficacy of the deployment process and the judicious selection and customization of the chosen instruments.
