Connect

Connect your tools to Hark

Pick the AI tool you use below and follow the steps — usually a button or one line. Once connected, every tool reads the same current state and leaves a note when it's done, so the next one picks up where the last left off.

MCP endpoint

https://harkstudio.io/mcp

Codex (CLI and IDE extension)

Two commands, then sign in from the browser.

codex mcp add hark --url https://harkstudio.io/mcp

codex mcp login hark

The login command opens a browser — sign in and approve. Then run codex mcp list to confirm; inside the Codex TUI, /mcp shows active servers.

Config lives in ~/.codex/config.toml (global) or .codex/config.toml (project). The IDE extension shares the same file; in the extension, gear menu → MCP servers → Authenticate if it shows OAuth required.

Verify it works

Ask your client: "List my Hark workspaces." Expected: your workspace names.

Then: "Create a project called Connection test in <workspace>." Expected: a new V-### appears in the app and the activity log shows the source ("via Claude Code", "via Codex", etc.). Delete the test venture afterward.

Troubleshooting

"Unauthorized request origin" — the client origin isn't allowlisted; retry from the latest app version, or email hello@harkstudio.io.
Consent screen loops / stale token — remove the connector in the client, sign out of Hark, sign back in, re-add the connector.
Tools list is empty — the connector isn't enabled for this chat (Claude and ChatGPT require enabling it per conversation).
Plan cap error — you've hit the monthly agent-call cap for this workspace; see billing.
Old endpoint — anything pointing at a lovable.app URL must be updated to harkstudio.io/mcp.
