Overview

AI-generated overview

Remote MSG91 docs server that helps an assistant find the right MSG91 API for SMS, OTP, WhatsApp, Email and Voice and call it correctly.

What you can do
  • Search MSG91 documentation with a natural-language question and get the most relevant passages with page URLs
  • Browse the MSG91 API docs one level at a time, from modules and pages down to individual endpoints and their OpenAPI files
  • Load quickstart instructions for running any MSG91 API from the terminal
When to use it
Useful when building or debugging integrations against MSG91 messaging APIs and you want the assistant to locate the correct endpoint, read its parameters, and get the right call shape instead of guessing.
Requirements
A remote Streamable HTTP endpoint; nothing to install and no API key for the server itself. Actually calling MSG91 APIs from the terminal needs Node.js 18+ and the docstar-cli package, plus your own MSG91 authkey entered in the terminal.
Before you install
The server itself needs no credentials, but the documented CLI flow asks for your MSG91 authkey; the README warns not to paste the authkey into an AI chat. Calls made through the CLI send real messages (SMS, WhatsApp, Email, Voice) and may incur MSG91 charges.

Installation

In SourceWeft

  1. Open MSG91 in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.msg91.mcp%2Fmcp/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

[MSG91]

MSG91 MCP

Lets AI assistants work with MSG91: find the right MSG91 API for SMS, OTP, WhatsApp, Email, Voice and more, read its parameters, and call it correctly.

This is a remote MCP server (Streamable HTTP) at https://mcp.msg91.com/mcp. Nothing to install and no API key for the server itself.

quickstart-msg91How to run any MSG91 API from the terminal

Connect from Cline

Install it from the Cline MCP Marketplace, or open MCP Servers → Configure MCP Servers and add this to cline_mcp_settings.json:

json
{  "mcpServers": {    "msg91": {      "type": "streamableHttp",      "url": "https://mcp.msg91.com/mcp",      "disabled": false,      "autoApprove": []    }  }}

Agent-driven install steps are in llms-install.md.

Connect from Claude Code

bash
claude mcp add --transport http msg91 https://mcp.msg91.com/mcp

Calling the MSG91 API

Run any MSG91 endpoint from your terminal (Node.js 18+):

bash
npx docstar-cli msg91 <module> <endpoint> --<flag> "<value>"# e.g.npx docstar-cli msg91 whatsapp send-message-in-text --integrated_number "91XXXXXXXXXX" \  --recipient_number "91YYYYYYYYYY" --content_type "text" --text "Hello"

The CLI asks for your MSG91 authkey in the terminal and can save it. Do not paste your authkey into an AI chat.

MCP Registry

server.json is the listing for the official MCP Registry, as com.msg91/mcp. The com.msg91 name is proven by owning the msg91.com domain.

One-time setup: create a signing key and publish its public half on msg91.com (Git Bash or any shell with OpenSSL):

bash
openssl genpkey -algorithm Ed25519 -out mcp-registry-key.pemecho "v=MCPv1; k=ed25519; p=$(openssl pkey -in mcp-registry-key.pem -pubout -outform DER | tail -c 32 | base64)"

Add the printed line as a TXT record on msg91.com. Keep mcp-registry-key.pem private and out of this repo.

Publish (bump version first for any later change):

bash
mcp-publisher login dns --domain msg91.com --private-key "$(openssl pkey -in mcp-registry-key.pem -noout -text | grep -A3 'priv:' | tail -n +2 | tr -d ' :\n')"mcp-publisher publish

get_msg91_api_docs

Get MSG91 API docs

Browse the MSG91 API docs, one level at a time. Call it without arguments to get the top level: the modules and pages with a short description and the endpoints they hold. Call it with `path` set to a module's or page's link (or path) to get what is inside it; each listing links the next level. Call it with `path` set to an endpoint's link ending in ".openapi.yml" to get that endpoint as an OpenAPI file: method, url, headers, query params, path variables, a request body example and sample responses. Fetch only the level you need.
