# How to connect Mailsoftly to Hermes Agent (paste one key, 20 tools) > Connect Mailsoftly to Hermes with ClawLink: paste your Mailsoftly key once and 20 tools work from chat. No MCP server to run, nothing stored on your machine. Web version: https://claw-link.dev/hermes/mailsoftly Most guides for giving Hermes Agent Mailsoftly 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 Mailsoftly setup: pair once in the browser and your always-on Hermes agent can act on Mailsoftly 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 Mailsoftly. 1. **Install ClawLink** — add the plugin to Hermes Agent once. 2. **Connect Mailsoftly** — 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 mailsoftly # connect Mailsoftly (browser OAuth) npx -y @useclawlink/cli actions mailsoftly # list available actions npx -y @useclawlink/cli run mailsoftly --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 Mailsoftly in the [ClawLink dashboard](https://claw-link.dev/dashboard) — paste your Mailsoftly API key once. Verify the connection by asking Hermes: > Use Mailsoftly to authenticate firm and walk me through the result in plain English. ### 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 Mailsoftly is connected in the dashboard, that agent calls the same 20 Mailsoftly tools over MCP.

ClawLink connects Mailsoftly to Hermes Agent and exposes 20 Mailsoftly 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 Mailsoftly integration](https://claw-link.dev/openclaw/mailsoftly) works the same way. ## What the Hermes Agent Mailsoftly integration can do 20 Mailsoftly tools are ready for Hermes Agent once the account is connected. ### All 20 Mailsoftly tools for Hermes | Tool | What it does | |---|---| | **Authenticate firm** `mailsoftly_authenticate_firm` | Validate the API key and retrieve firm details | | **Get contact** `mailsoftly_get_contact` | Retrieve a specific contact by ID from Mailsoftly | | **Get contact fields** `mailsoftly_get_contact_fields` | Fetch all contact fields available for a firm, excluding hidden columns | | **Get contact list** `mailsoftly_get_contact_list` | Retrieve details of a specific contact list by ID | | **Get contact list contacts** `mailsoftly_get_contact_list_contacts` | Retrieve all contacts within a specific contact list | | **Get contact lists** `mailsoftly_get_contact_lists` | Retrieve all contact lists for the authenticated firm | | **Get contacts** `mailsoftly_get_contacts` | Retrieve all contacts associated with a firm | | **Get custom fields** `mailsoftly_get_custom_fields` | Retrieve all custom fields defined for the authenticated firm | | **Get email status** `mailsoftly_get_email_status` | Fetch the status of a specific email draft by its ID | | **Get tags** `mailsoftly_get_tags` | Retrieve all tags associated with the authenticated firm | | **Search contacts** `mailsoftly_search_contacts` | Search for contacts matching specified criteria in Mailsoftly | | **Add contact to contact list** `mailsoftly_add_contact_to_contact_list` | Add an existing contact to a specific contact list | | **Add custom field to contact** `mailsoftly_add_custom_field_to_contact` | Add a custom field value to an existing contact | | **Assign tags to contact** `mailsoftly_assign_tags_to_contact` | Assign multiple tags to an existing contact at once | | **Create contact** `mailsoftly_create_contact` | Create a new contact for the authenticated firm with email, first name, and last name | | **Create contact list** `mailsoftly_create_contact_list` | Create a new contact list for the authenticated firm | | **Create emails** `mailsoftly_create_emails` | Create one or more email drafts in Mailsoftly | | **Create or update contact** `mailsoftly_create_or_update_contact` | Create a new contact or update an existing contact in Mailsoftly | | **Send email** `mailsoftly_send_email` | Send an existing email draft that is marked as ready | | **Update contact** `mailsoftly_update_contact` | Update an existing contact's information in Mailsoftly | ## Example prompts **Authenticate Firm** > Use Mailsoftly to authenticate firm and walk me through the result in plain English. **Get Contact** > Pull the relevant data from Mailsoftly, summarize it in plain English, and point out anything that needs attention. **Get Contact Fields** > Pull the relevant data from Mailsoftly, summarize it in plain English, and point out anything that needs attention. **Get Contact List** > Pull the relevant data from Mailsoftly, summarize it in plain English, and point out anything that needs attention. ## 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 Mailsoftly working from chat. | | Manual | ClawLink | |---|---|---| | **Credential handling** | Collect, validate, store, and rotate the Mailsoftly API key yourself, then make sure every tool call uses the right account. | Users complete the hosted ClawLink setup once and the connected Mailsoftly 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 Mailsoftly. | 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 Mailsoftly actions to the runtime in a format your agent can reliably use. | 20 tools for Mailsoftly are already exposed through ClawLink, so the agent can read and act from chat immediately. | ## ClawLink vs. Composio Composio also exposes Mailsoftly 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 Mailsoftly in the browser, and the 20 tools above work from chat. There is no SDK and no config file, and the Mailsoftly key you paste at setup is stored server-side rather than kept in your environment. Choosing between them? Read the full [Composio alternatives](https://claw-link.dev/hub/composio-alternatives) comparison. ### Hermes paired but still can't use Mailsoftly 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 Mailsoftly 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 Mailsoftly tools Mailsoftly 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 Mailsoftly 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. ### Mailsoftly 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 Mailsoftly 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 Mailsoftly integration? Yes. ClawLink is the fastest way to connect Hermes to Mailsoftly: link your Mailsoftly account once in the browser and Hermes Agent can call the Mailsoftly API through 20 ready-made tools — no custom code or token handling. ### How do I connect Mailsoftly 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 Mailsoftly in the dashboard and Hermes can use it from the next message — no config files, and the Mailsoftly key you paste is stored server-side instead of in your environment. ### How long does it take to connect Mailsoftly to Hermes Agent? About two minutes. Sign in, click Connect next to Mailsoftly in the dashboard, authenticate, and Hermes Agent can use it from the next chat message. ### Why use ClawLink instead of wiring Mailsoftly 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 Mailsoftly working from chat. ### Hermes paired but still can't use Mailsoftly 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`. ## Related - [Connect ActiveCampaign](https://claw-link.dev/hermes/activecampaign) — Marketing automation, CRM, and email marketing - [Benchmark Email](https://claw-link.dev/hermes/benchmark-email) — Benchmark Email is a comprehensive email marketing platform offering tools for creating, sending, and analyzing email campaigns. - [Connect Mailchimp](https://claw-link.dev/hermes/mailchimp) — Create email campaigns and manage audiences
