# How to connect Msg91 to Hermes Agent (paste one key, 8 tools) > Connect Msg91 to Hermes with ClawLink: paste your Msg91 key once and 8 tools work from chat. No MCP server to run, nothing stored on your machine. Web version: https://claw-link.dev/hermes/msg91 Most guides for giving Hermes Agent Msg91 access start with registering your own OAuth app or pasting API keys into env files, then leave the token refresh and tool wiring to you. ClawLink gives Hermes a more practical Msg91 setup: pair once in the browser and your always-on Hermes agent can act on Msg91 for you, reading and doing real work on your behalf with no auth, token refresh, or tool wiring to build yourself. ## Setup It takes three steps to connect Hermes to Msg91. 1. **Install ClawLink** — add the plugin to Hermes Agent once. 2. **Connect Msg91** — one-click OAuth in the ClawLink dashboard. 3. **Use it from chat** — ask Hermes Agent in plain English. **Paste this into Hermes to set up ClawLink:** > Set up ClawLink for Hermes and tell me when it's ready. > 1. Install the plugin: `hermes plugins install ClawLink-HQ/hermes-plugin --enable` > 2. Start pairing with `hermes clawlink begin`. It prints an approval link, so show me the link and stop, don't wait. > 3. I'll approve it in my browser, then reply "approved". > 4. When I say approved, finish setup: `hermes clawlink finish` > 5. Then run `hermes clawlink test` and tell me whether ClawLink is ready. **Alternative for any agent (no plugin needed):** if the Hermes Agent plugin route isn't available or doesn't work, any AI agent with shell access can use the ClawLink CLI instead: ```bash npx -y @useclawlink/cli login # sign in via browser — no API key to paste npx -y @useclawlink/cli connect msg91 # connect Msg91 (browser OAuth) npx -y @useclawlink/cli actions msg91 # list available actions npx -y @useclawlink/cli run msg91 --input '' # execute (add --confirm for writes) ``` ### Install by command The prompt above walks Hermes through this. By hand, it is four commands and a browser approval: ```bash hermes plugins install ClawLink-HQ/hermes-plugin --enable hermes clawlink begin # prints an approval link — open it and approve hermes clawlink finish # after approving in the browser hermes clawlink test ``` Then connect Msg91 in the [ClawLink dashboard](https://claw-link.dev/dashboard) — paste your Msg91 API key once. Verify the connection by asking Hermes: > Pull the relevant data from Msg91, summarize it in plain English, and point out anything that needs attention. ### Using a different agent? The Hermes plugin is one client of ClawLink's MCP server. Claude Code, Cursor, Codex, or any agent that can run a shell command pairs with the same ClawLink account through the CLI: ```bash npx -y @useclawlink/cli login ``` `login` opens the same browser approval and stores a credential locally. Once Msg91 is connected in the dashboard, that agent calls the same 8 Msg91 tools over MCP.

ClawLink connects Msg91 to Hermes Agent and exposes 8 Msg91 tools your agent can call over [MCP](https://claw-link.dev/learn/what-is-an-mcp-server), with [hosted auth](https://claw-link.dev/learn/oauth-for-ai-agents) and nothing to run or maintain yourself. Using OpenClaw instead? The [OpenClaw Msg91 integration](https://claw-link.dev/openclaw/msg91) works the same way. ## What the Hermes Agent Msg91 integration can do 8 Msg91 tools are ready for Hermes Agent once the account is connected. ### All 8 Msg91 tools for Hermes | Tool | What it does | |---|---| | **Get event types** `msg91_get_event_types` | Retrieves all event types configured in MSG91 Segmento | | **Get failed events** `msg91_get_failed_events` | Retrieve failed user events from a MSG91 Segmento campaign | | **List campaigns** `msg91_list_campaigns` | List all campaigns in Segmento | | **Create user events** `msg91_create_user_events` | Create and track user events in MSG91 Segmento for customer behavior analysis and segmentation | | **Resend otp** `msg91_resend_otp` | Resend OTP to the same mobile number via text message or voice call | | **Send otp** `msg91_send_otp` | Send OTP (One-Time Password) to a mobile number using a pre-configured MSG91 template | | **Send sms v5** `msg91_send_sms_v5` | Send SMS messages using pre-defined templates via MSG91 Flow API v5 | | **Verify otp** `msg91_verify_otp` | Verify an OTP (One-Time Password) sent to a mobile number | ## Example prompts **Get Event Types** > Pull the relevant data from Msg91, summarize it in plain English, and point out anything that needs attention. **Get Failed Events** > Pull the relevant data from Msg91, summarize it in plain English, and point out anything that needs attention. **List Campaigns** > List the relevant items in Msg91, group them by priority, and recommend what Hermes should do next. **Create User Events** > Create it in Msg91 for me, then confirm the important fields before you finish. ## ClawLink vs. building it yourself The alternative to ClawLink is usually manual API key setup plus your own token handling, permission troubleshooting, and tool plumbing for Hermes Agent. That is fine if you want to build and maintain the integration yourself. Most teams just want Msg91 working from chat. | | Manual | ClawLink | |---|---|---| | **Credential handling** | Collect, validate, store, and rotate the Msg91 API key yourself, then make sure every tool call uses the right account. | Users complete the hosted ClawLink setup once and the connected Msg91 account becomes available to the agent without you building credential management. | | **Ongoing maintenance** | You own refresh logic, permission debugging, environment config, and every provider-specific edge case for Msg91. | ClawLink handles the repetitive integration plumbing so your team can focus on the workflow instead of the infrastructure. | | **Agent usability** | You still need to expose the right Msg91 actions to the runtime in a format your agent can reliably use. | 8 tools for Msg91 are already exposed through ClawLink, so the agent can read and act from chat immediately. | ## ClawLink vs. Composio Composio also exposes Msg91 to AI agents. It is developer infrastructure: Python and TypeScript SDKs, an MCP server, and a catalog past 1,000 apps, aimed at teams shipping agent products. ClawLink is built for Hermes Agent users instead. You install the plugin once, connect Msg91 in the browser, and the 8 tools above work from chat. There is no SDK and no config file, and the Msg91 key you paste at setup is stored server-side rather than kept in your environment. Choosing between them?

If you ran finish before approving, or the approval link expired, run `hermes clawlink begin` again to get a fresh link. Confirm the plugin was installed with `--enable`, then verify with `hermes clawlink test`. ### Connection succeeds but no tools appear Reconnect Msg91 from the dashboard, then start a fresh chat if the runtime still has the old tool catalog loaded. ### "Tool schema not loaded yet" error when calling Msg91 tools Msg91 tool schemas load on demand the first time a tool runs and are cached after that, so this error usually clears on its own: wait a few seconds and retry the same request. If every Msg91 call keeps failing with it in a fresh chat, reconnect from the dashboard, and contact support if it still persists — that pattern points to a configuration problem on our side, not something you can fix by reconnecting again. ### Msg91 returns 403 or "permission denied" on one action while others work Two usual causes. The connected account may not have access to the specific workspace, inbox, store, or project in the request — check that first. If access looks right, the agent may have sent a placeholder value (like "YOUR_ID" or an example id from documentation) instead of a real one: ask it to run a list or search tool first, then retry the action with a real id from those results. Most failures at this stage are one of these two, not ClawLink bugs. ### API key setup works but results look incomplete Double-check that the API key for Msg91 has the right scopes or account access. A valid key can still be too limited for some reads or writes. ### Is there a Hermes Agent Msg91 integration? Yes. ClawLink is the fastest way to connect Hermes to Msg91: link your Msg91 account once in the browser and Hermes Agent can call the Msg91 API through 8 ready-made tools — no custom code or token handling. ### How do I connect Msg91 to Hermes with ClawLink? Install the plugin with `hermes plugins install ClawLink-HQ/hermes-plugin --enable`, then pair once: run `hermes clawlink begin`, approve the link in your browser, and run `hermes clawlink finish`. Connect Msg91 in the dashboard and Hermes can use it from the next message — no config files, and the Msg91 key you paste is stored server-side instead of in your environment. ### How long does it take to connect Msg91 to Hermes Agent? About two minutes. Sign in, click Connect next to Msg91 in the dashboard, authenticate, and Hermes Agent can use it from the next chat message. ### Why use ClawLink instead of wiring Msg91 up myself? The alternative to ClawLink is usually manual API key setup plus your own token handling, permission troubleshooting, and tool plumbing for Hermes Agent. That is fine if you want to build and maintain the integration yourself. Most teams just want Msg91 working from chat. ### Hermes paired but still can't use Msg91 Pairing is a two-step handshake: run `hermes clawlink begin`, approve the link in your browser, then run `hermes clawlink finish`. If you ran finish before approving, or the approval link expired, run `hermes clawlink begin` again to get a fresh link.
