How to connect LMNT to Hermes Agent
Connect LMNT to Hermes with ClawLink: paste your LMNT key once and 8 tools work from chat. No MCP server to run, nothing stored on your machine.
LMNTAPI KEYMCPGenerate speech and voice from text using LMNT API. Once connected, Hermes Agent can read and act on LMNT from chat — pairing, token refresh, and tool wiring handled for you.
Most guides for giving Hermes Agent LMNT 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 LMNT setup: pair once in the browser and your always-on Hermes agent can act on LMNT for you, reading and doing real work on your behalf with no auth, token refresh, or tool wiring to build yourself.
Copy this prompt into Hermes to install the plugin and pair your account.
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. It prints an approval link, so show me the link and stop, don't wait:
hermes clawlink begin
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.Setup
It takes three steps to connect Hermes to LMNT.
1Install and pair
Install the ClawLink plugin, then pair Hermes with a one-time browser approval:
hermes plugins install ClawLink-HQ/hermes-plugin --enable- 2
Connect LMNT
Paste your API key in the dashboard.

Use it from chat
Ask Hermes Agent: "What can you do with LMNT?"
Install by command
The prompt above walks Hermes through this. By hand, it is four commands and a browser approval:
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 testThen connect LMNT in the ClawLink dashboard — paste your LMNT API key once.
Verify the connection by asking Hermes:
Create it in LMNT for me, then confirm the important fields before you finish.
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:
npx -y @useclawlink/cli loginlogin opens the same browser approval and stores a credential locally. Once LMNT is connected in the dashboard, that agent calls the same 8 LMNT tools over MCP. Full setup for MCP clients and shell agents: connect apps to any AI agent.
LMNT MCP for Hermes
Looking for a LMNT MCP server for Hermes Agent? ClawLink connects LMNT to Hermes Agent and exposes 8 LMNT tools your agent can call over MCP, with hosted auth and nothing to run or maintain yourself. Using OpenClaw instead? The OpenClaw LMNT integration works the same way.
What the Hermes Agent LMNT integration can do
8 LMNT tools are ready for Hermes Agent once the account is connected. The 7 below are the ones people reach for most; your agent can call all 8.
7 of 8 LMNT tools for Hermes
| Tool | What it does |
|---|---|
Create voice lmnt_create_voice | Creates a custom voice in LMNT by training on uploaded audio samples. The voice can then be used for text-to-speech synthesis. Returns the voice ID and metadata upon successful creation. |
Generate speech with metadata lmnt_generate_speech_with_metadata | Generates speech from text and returns JSON with base64-encoded audio and optional word-level timing metadata. Use when you need the synthesis seed or word timestamps for subtitle synchronization. |
Get account lmnt_get_account | Retrieves account information including subscription plan details and current usage statistics. |
Get voice info lmnt_get_voice_info | Gets metadata for a specific LMNT voice, including active status, supported languages, and plan availability. Useful for validating a voice ID before using it in synthesis requests. |
Get voices list lmnt_get_voices_list | Retrieves a list of available voices from LMNT. Returns both system-provided preset voices and any custom voices you have created. |
Synthesize speech lmnt_synthesize_speech | Synthesizes speech from text using LMNT's AI voices. Converts text (up to 5000 characters) into natural-sounding speech audio using a specified voice. |
Update voice lmnt_update_voice | Updates information about a specific voice in LMNT. You can update the name, description, gender, starred status, and unfreeze state of a voice. |

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 LMNT working from chat.
| Manual | ClawLink | |
|---|---|---|
| Credential handling | Collect, validate, store, and rotate the LMNT API key yourself, then make sure every tool call uses the right account. | Users complete the hosted ClawLink setup once and the connected LMNT 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 LMNT. | 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 LMNT actions to the runtime in a format your agent can reliably use. | 8 tools for LMNT are already exposed through ClawLink, so the agent can read and act from chat immediately. |
ClawLink vs. Composio
Composio also exposes LMNT 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 LMNT in the browser, and the 8 tools above work from chat. There is no SDK and no config file, and the LMNT key you paste at setup is stored server-side rather than kept in your environment. Choosing between them?

Troubleshooting
Hermes paired but still can't use LMNT
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. Confirm the plugin was installed with --enable, then verify with hermes clawlink test.
Connection succeeds but no tools appear
Reconnect LMNT 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 LMNT tools
LMNT 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 LMNT 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.
LMNT 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 LMNT has the right scopes or account access. A valid key can still be too limited for some reads or writes.
