## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Endpoint Security**: 74/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Nothing on it is marked destructive, but we can't show that an anonymous caller can only read: full credit needs the server to list at least one tool and every tool to be verifiably read-only. We use a best-effort check of tool names and descriptions to tell read-only tools from tools that change things, so some genuinely read-only tools may not get full credit. Names that start with a read verb (get, list, read, search and similar) and accurate readOnlyHint annotations help. Meet that to earn full credit, or require authorisation.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 69/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 313 tokens (~104/item across 3 items; 3 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 20/100
  - Stability observed for 6 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 3 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (3)

### `search_msg91_docs` (~79 tokens)

Search the MSG91 documentation with a natural-language question. Returns the most relevant passages with their page URLs.

Input parameters:

- `collectionIds` (array, required): Always send exactly these collection ids, unchanged: they are the documentation sites searched.
- `query` (string, required): What to look for, e.g. "how do I send a WhatsApp template message"

### `get_msg91_api_docs` (~202 tokens)

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.

Input parameters:

- `path` (string): A link from a listing, exactly as given (e.g. "https://docs.example.com/sms/llms.txt" or ".../sms/send-sms.openapi.yml"), or just the path ("sms", "sms/send-sms.openapi.yml"). Leave it out for the to…

### `quickstart-msg91` (~32 tokens)

## Common questions

### What is the MSG91 MCP server?

MSG91 is an MCP server listed in the public MCP registry as com.msg91.mcp/mcp. Find and call the right MSG91 API for SMS, OTP, WhatsApp, Email and Voice. This page covers its hosted endpoint (https://mcp.msg91.com/mcp).

### Is the MSG91 MCP server safe to use?

MSG91 scores 73 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the MSG91 MCP server expose?

MSG91 exposes 3 tools: search_msg91_docs, get_msg91_api_docs, quickstart-msg91. Their descriptions and schemas cost roughly 313 tokens of context every time the server is loaded.

### Does the MSG91 MCP server require authentication?

No. We connected to MSG91 without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the MSG91 MCP server still maintained?

MSG91 is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What did VerifyMCP test on the MSG91 MCP server?

VerifyMCP ran 13 checks on MSG91, covering TLS certificate, Authorization, HTTPS, HSTS header and 9 more. Supply Chain Security and Provenance & Transparency do not apply to a hosted endpoint, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
