Required Credentials

Replace the placeholder values with your actual Exotel credentials:

YOUREXOTELTOKEN: Base64 Encoded API Credentials

This token is created by encoding your Exotel API Key and Secret in Base64 format.

Step 1: Get your API credentials from Exotel Dashboard

1. Log into your Exotel Dashboard
2. Navigate to Settings → API Settings
3. Copy your API Key and API Secret

Step 2: Create the Base64 token

Format: api_key:api_secret (colon-separated)

Example: If your API Key is abc123 and API Secret is xyz789, combine them as: abc123:xyz789

Step 3: Encode to Base64

You can use any of these methods:

Online Tool:

• Visit base64encode.org
• Enter your api_key:api_secret string
• Copy the encoded result

Command Line (Mac/Linux):

echo -n "your_api_key:your_api_secret" | base64

Command Line (Windows):

[Convert]::ToBase64String([Text.Encoding]::UTF8.GetBytes("your_api_key:your_api_secret"))

Other Required Values:

• YOURFROMNUMBER: Your registered Exotel phone number (from Dashboard → Numbers)
• YOURDLTTEMPLATE: DLT template ID for SMS compliance (from Dashboard → DLT)
• YOURDLTENTITY: DLT entity ID for SMS compliance (from Dashboard → DLT)
• YOURCALLERID: Your registered caller ID (from Dashboard → Numbers)
• YOURACCOUNTSID: Your Exotel account SID (from Dashboard → API Settings)
• YOURSUBDOMAIN: Your Exotel account SubDomain (from Dashboard → API Settings)
• YOUREXOTELDASHBOARDBASEURL: Your Exotel Dashboard base url

Conversational Intelligence Credentials:

• YOURCQAAPI_KEY: API key generated from the Conversational Intelligence console
• YOURCQAACCOUNT_ID: Your account ID (visible in the Conversational Intelligence console)
• YOURCQAHOST: Host URL (default: https://cqa-console.in.exotel.com)

> Note: Conversational Intelligence credentials are only required if you plan to use the quality analysis tools. SMS and Voice tools work independently.

VoiceBot Credentials:

• YOURVOICEBOTAPI_KEY: API key from the VoiceBot platform
• YOURVOICEBOTAPI_TOKEN: API token from the VoiceBot platform
• YOURVOICEBOTACCOUNT_ID: Your VoiceBot account ID (e.g. ameyo5m)
• YOURCALLSAPI_KEY: Exotel CPaaS API key for placing bot-powered calls
• YOURCALLSAPI_TOKEN: Exotel CPaaS API token for placing bot-powered calls
• YOURCALLSACCOUNT_ID: Exotel CPaaS account SID for calls (can differ from VoiceBot account)
• callsbaseurl: Exotel Calls API base URL (default: https://api.exotel.com)

> Note: VoiceBot credentials are only required if you plan to use the VoiceBot tools. The VoiceBot management API (list/create/delete bots) uses voicebot_* credentials, while placing actual calls uses calls_* credentials.

Conversational Intelligence Services

Exotel Conversational Intelligence analyzes 100% of customer conversations across voice and digital channels using AI, delivering real-time quality intelligence. The platform reviews thousands of conversations in minutes, maintaining over 90% accuracy in objective evaluations — replacing manual sampling with continuous, automated QA at scale.

Authentication: CQA tools use two authentication methods:

• Setup tools (login, quality profiles, API keys, assignment rules) use JWT authentication obtained via the login tool -- no pre-configured credentials needed
• Ingestion & analysis tools (ingest, status, results) use your cqa_api_key configured in the MCP auth header

API key: Generate your API key from the Conversational Intelligence console or via the exotel_cqa_create_api_key MCP tool, then provide it as cqa_api_key in the MCP configuration.

Login

Authenticate with CQA to get a JWT token required for setup operations (quality profiles, API keys, assignment rules).

Example:

Login to CQA as admin@exotel.com on tenant exotel_support

Create Quality Profile

Create a complete quality profile with categories, sub-categories, and KPIs in a single call. The profile is automatically created with AI analysis enabled.

Example:

Create a quality profile called "Support Evaluation" with category "Communication", sub-category "Clarity", and KPIs: "Clear Speech" (Yes/No, options: Yes=1/No=0), "Professional Tone" (Yes/No, options: Yes=1/No=0)

> Supported KPI types: Yes/No, Selection, Rating, Text > > Options are REQUIRED for Yes/No, Selection, and Rating types. Each option needs label (string) and weightage (integer). Rating options also need type: "STAR". Text KPIs do not support options. > > Additional optional KPI fields: is_scoring_allowed, is_critical, is_mandatory, is_comment_mandatory, is_dispute_allowed, criticality_level. All fields provided in categoriesJson are passed through to the API. > > Partial failure handling: If a sub-step (category, sub-category, or KPI creation) fails, the tool returns a partial result containing the profile_id and any categories created before the failure, along with a recovery hint.

Create API Key

Generate an API key for programmatic ingestion and analysis. Keys are scoped to the account.

Example:

Create a CQA API key called "support-api-key"

> Note: There is a per-tenant limit on active API keys (currently 2). A 409 response means the limit is reached -- revoke an existing key first.

Create Assignment Rule

Create a rule that routes interactions to quality profiles based on metadata filters (e.g., route all calls with source=support to a specific quality profile).

Example:

Create an assignment rule that routes calls with source "support" to quality profile a1b2c3d4-e5f6-7890-abcd-ef1234567890 at 100% sampling

> filterGroupJson is REQUIRED. The tool will return an error if no filter is provided. > > Supported filter operators: IS, ISNOT, CONTAINS, NOTCONTAINS, GREATERTHAN, LESSTHAN, GREATEROREQUAL, LESSOREQUAL

Ingest Single Interaction

Submit a single call recording or transcript for quality analysis. Provide at least one of audioUrl, transcriptUrl, or inline transcriptText (max 200KB).

Example:

Ingest interaction call-001 (voice channel) with audio at https://s3.example.com/call-001.wav in English

Quality Profile / Rule / API Key Management

JWT setup tools also support list/get/update/delete/duplicate for profiles, list/update/delete for assignment rules, list/revoke for API keys, metadata config, and list analyses.

Destructive tools (delete_*, revoke_api_key) require confirm=true. Empty KPI wipe on profile update requires confirmWipeKpis=true. accountId must match cqa_account_id in the MCP auth header when that header field is set.

Ingest Batch

Submit up to 100 interactions as a single batch job.

Example:

Ingest a batch of 3 voice interactions for quality analysis

Ingest File

Submit a CSV file containing multiple interactions for bulk analysis.

Example:

Submit https://s3.example.com/calls.csv as a CSV file for quality analysis ingestion

Get Interaction Status

Check the processing status of an ingested interaction.

Example:

Check the status of interaction call-2026-04-01-001

Track Job

Monitor the progress of a batch or file ingestion job.

Example:

Track ingestion job d4f5a6b7-c8d9-4e0f-a1b2-c3d4e5f6a7b8

Get Analysis Results

Retrieve the full quality scoring breakdown for a completed analysis.

Example:

Get the quality analysis for analysis ID a1b2c3d4-e5f6-7890-abcd-ef1234567890

VoiceBot Services

Create and manage AI-powered VoiceBots that handle entire phone conversations autonomously.

List VoiceBots

List all VoiceBots on your account with pagination and status filtering.

Example:

Create VoiceBot

Create a new VoiceBot by describing its personality and purpose in natural language.
