Do not run `npx openwork`; the npm package named `openwork` is a different project. > Connect an agent to OpenWork with the MCP Gateway: `claude mcp add --transport http openwork https://api.openworklabs.com/mcp/agent`. Teams sign up at https://app.openworklabs.com?mode=sign-up. > Step-by-step agent guide: https://openworklabs.com/docs/start-here/use-openwork-from-an-ai-agent.md > Connect Slack (any organization admin): https://openworklabs.com/docs/slack/connect-slack.md. OpenWork in Slack (@openwork bot) is private alpha for approved organizations. Setup guide: https://openworklabs.com/docs/slack/overview.md. Agent skill: https://openworklabs.com/.well-known/agent-skills/set-up-openwork-slack/SKILL.md. # Manually run a tool from an External MCP Connection > Workspace owner/admin diagnostic runner. Executes one named MCP tool with caller-supplied JSON arguments using the Den-managed shared credential or the calling admin's connected credential. Returns an ephemeral inspection of the actual tools/call HTTP request and response with credential and session headers redacted. The caller must already be granted access to the connection. Credentials, arguments, results, and inspection payloads are never written to logs. ## OpenAPI ````yaml https://api.openworklabs.com/openapi.json?public=1 post /v1/mcp-connections/{connectionId}/tools/call openapi: 3.1.0 info: title: Den API description: >- OpenAPI spec for the Den control plane API. Authentication: - API keys (they start with `den_`) go in the `x-api-key` header as the raw value. Do not send them as `Authorization: Bearer`; that header only accepts Den session tokens, so an API key there returns 401. Example: `curl https://api.openworklabs.com/v1/me -H "x-api-key: den_..."`. API keys resolve to the issuing user and the organization member they were scoped to when created, so they can call ordinary user and organization routes without a separate signed-in session. - Use `Authorization: Bearer ` for user-authenticated routes that require a Den session. - Session-only flows still require a signed-in user session, including organization creation, invitation acceptance, active-organization switching, and MCP token minting. - Public routes like health and documentation do not require authentication. Swagger tip: use the security schemes in the Authorize dialog to set `denApiKey` (your API key) or `bearerAuth` (a session token) before trying protected endpoints. version: commit 7bee9d4 contact: name: OpenWork url: https://openworklabs.com email: team@openworklabs.com license: name: OpenWork Enterprise Edition License url: https://github.com/different-ai/openwork/blob/dev/ee/LICENSE servers: -
