# How to connect Codemagic to Hermes Agent (paste one key, 22 tools) > Connect Codemagic to Hermes with ClawLink: paste your Codemagic key once and 22 tools work from chat. No MCP server to run, nothing stored on your machine. Web version: https://claw-link.dev/hermes/codemagic Most guides for giving Hermes Agent Codemagic 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 Codemagic setup: pair once in the browser and your always-on Hermes agent can act on Codemagic 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 Codemagic. 1. **Install ClawLink** — add the plugin to Hermes Agent once. 2. **Connect Codemagic** — 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 codemagic # connect Codemagic (browser OAuth) npx -y @useclawlink/cli actions codemagic # list available actions npx -y @useclawlink/cli run codemagic --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 Codemagic in the [ClawLink dashboard](https://claw-link.dev/dashboard) — paste your Codemagic API key once. Verify the connection by asking Hermes: > Use Codemagic to api v3 meta get meta 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 Codemagic is connected in the dashboard, that agent calls the same 22 Codemagic tools over MCP.

ClawLink connects Codemagic to Hermes Agent and exposes 22 Codemagic 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 Codemagic integration](https://claw-link.dev/openclaw/codemagic) works the same way. ## What the Hermes Agent Codemagic integration can do 22 Codemagic tools are ready for Hermes Agent once the account is connected. The 20 below are the ones people reach for most; your agent can call all 22. ### 20 of 22 Codemagic tools for Hermes | Tool | What it does | |---|---| | **API v3 meta get meta** `codemagic_api_v3_meta_get_meta` | Get metadata about Codemagic including public IP addresses in use (in CIDR notation) | | **API v3 variable groups variable group ID get group** `codemagic_api_v3_variable_groups_variable_group_id_get_group` | Retrieve information about a specific variable group including its name and configuration | | **Get all builds** `codemagic_get_all_builds` | List all builds with optional filters for appId, workflowId, and branch | | **Get API key** `codemagic_get_api_key` | Retrieve the API key for the authenticated user from the server | | **Get shorebird meta** `codemagic_get_shorebird_meta` | Retrieve information about Shorebird integration | | **Get user** `codemagic_get_user` | Retrieve information about the currently authenticated user | | **Get variable groups** `codemagic_get_variable_groups` | Retrieve paginated list of variable groups for an application | | **Get variables** `codemagic_get_variables` | Retrieve paginated list of variables for a specific variable group | | **Retrieve all applications** `codemagic_retrieve_all_applications` | Retrieve all applications added to Codemagic | | **Retrieve an application** `codemagic_retrieve_an_application` | Retrieve a single application by its unique identifier | | **Retrieve caches for application** `codemagic_retrieve_caches_for_application` | Retrieve a list of caches for a specific application | | **Add application from private repo** `codemagic_add_application_from_private_repo` | Create an application from a private repository using SSH key authentication | | **Add new application** `codemagic_add_new_application` | Add a Git repository to the applications list in Codemagic | | **API v3 variable groups variable group ID update** `codemagic_api_v3_variable_groups_variable_group_id_update` | Change a variable group's name and security settings | | **Invite team member** `codemagic_invite_team_member` | Invite a new team member to a Codemagic team | | **Receive webhook** `codemagic_receive_webhook` | Receive webhook payloads from Git providers to trigger builds automatically | | **Start new build** `codemagic_start_new_build` | Start a new build for an application with specified workflow and branch or tag | | **Update variable** `codemagic_update_variable` | Update an existing variable within a specified variable group in Codemagic | | **Remove team member** `codemagic_remove_team_member` | Remove a collaborator or revoke a pending invitation from a Codemagic team | | **Stop preview** `codemagic_stop_preview` | Stop an app preview | ## Example prompts **Api V3 Meta Get Meta** > Use Codemagic to api v3 meta get meta and walk me through the result in plain English. **Api V3 Variable Groups Variable Group Id Get Group** > Use Codemagic to api v3 variable groups variable group id get group and walk me through the result in plain English. **Get All Builds** > Pull the relevant data from Codemagic, summarize it in plain English, and point out anything that needs attention. **Get Api Key** > Pull the relevant data from Codemagic, 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 Codemagic working from chat. | | Manual | ClawLink | |---|---|---| | **Credential handling** | Collect, validate, store, and rotate the Codemagic API key yourself, then make sure every tool call uses the right account. | Users complete the hosted ClawLink setup once and the connected Codemagic 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 Codemagic. | 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 Codemagic actions to the runtime in a format your agent can reliably use. | 22 tools for Codemagic are already exposed through ClawLink, so the agent can read and act from chat immediately. | ## ClawLink vs. Composio Composio also exposes Codemagic 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 Codemagic in the browser, and the 22 tools above work from chat. There is no SDK and no config file, and the Codemagic 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 Codemagic 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 Codemagic tools Codemagic 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 Codemagic 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. ### Codemagic 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 Codemagic 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 Codemagic integration? Yes. ClawLink is the fastest way to connect Hermes to Codemagic: link your Codemagic account once in the browser and Hermes Agent can call the Codemagic API through 22 ready-made tools — no custom code or token handling. ### How do I connect Codemagic 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 Codemagic in the dashboard and Hermes can use it from the next message — no config files, and the Codemagic key you paste is stored server-side instead of in your environment. ### How long does it take to connect Codemagic to Hermes Agent? About two minutes. Sign in, click Connect next to Codemagic in the dashboard, authenticate, and Hermes Agent can use it from the next chat message. ### Why use ClawLink instead of wiring Codemagic 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 Codemagic working from chat. ### Hermes paired but still can't use Codemagic Pairing is a two-step handshake: run `hermes clawlink begin`, approve the link in your browser, then run `hermes clawlink finish`.
