MCP Connections
Promptmark can now talk to other tools. Connect to any MCP-compatible server, browse its capabilities, and use those tools directly in conversations, playbooks, and tests – no glue code required.
What’s new
- Connect to any MCP server – Add connections to external tool servers like Civic Hub, internal APIs, or any service that speaks MCP. Each connection stores its own credentials and health status.
- Flexible authentication – Choose the auth method that fits your server: bearer token, API key, OAuth, or custom headers. Promptmark handles token refresh and reconnection automatically.
- Civic Auth integration – First-class support for Civic’s OAuth flow. Tools that require user authorization show a one-click connect button; Promptmark polls for completion and picks up the token seamlessly.
- Tool discovery – Once connected, Promptmark fetches the server’s tool catalog automatically. Browse tools by name and description, mark favorites for quick access, and refresh the catalog when the server updates.
- Manual tool execution – Run any discovered tool directly from its detail page. Fill in the input schema, execute, and watch results stream back in real time.
- AI-powered tool use – Attach tools to conversations and playbooks and let the AI call them as needed. The model sees tool descriptions in its context and decides when to invoke them – you stay in control of which tools are available.
- Tool picker – A searchable picker lets you attach tools to prompts, conversations, and tests. Bulk select or clear tools per connection, with “+N more” overflow chips when many are attached.
- Anthropic native tools – Web search and code execution are available for Anthropic models directly in the tool picker, no external server needed.
