• Example: A task to read the most recent email and transform it into a haiku.

6. Deployment and Infrastructure:

• Kubernetes: The production-grade setup is expected to be deployed into a Kubernetes cluster, with a Helm chart available.
• Docker: A simple docker run command is available for local testing and trying out the platform.
• Authentication (OAuth): The transcript acknowledges the complexity of OAuth in the MCP ecosystem, noting that it often requires pre-setup for demonstration purposes.

7. Administrator Dashboard:

• Authentication Provider Setup: Administrators configure an authentication provider (e.g., OAuth providers) to manage user access.
• Model Provider Setup: A plug-in system allows integration with major model providers to power the Obot Chat experience.
• Catalog Management:
  • Official Catalog: Obot ships with an official catalog that is continuously updated.
  • Custom Server Addition: Administrators can add their own servers manually via the web console or from a Git server.
  • GitOps Integration: The official catalog is hosted on GitHub, and custom catalogs can be managed via GitOps principles, using Pull Requests for review and automatic syncing.
• Adding Servers: Three options are available:
  • Single-User Server: For MCP servers written with the older standard.io protocol, requiring an instance per user.
  • Multi-User Server: For scalable, multi-tenant servers written with the streamable-http protocol.
  • Remote Server: To expose existing MCP servers running elsewhere without needing to deploy them.
• Example (Adding a Remote Server): Adding Linear's MCP server by providing its URL.
• Access Control:
  • Granular Control: Administrators control which users or teams have access to specific servers.
  • Group Support: Initial group support for GitHub has been merged, with plans to expand to other OAuth providers.
  • Catch-All Rule: A rule can be set to expose all servers to all users.
• Connecting to Added Servers: Demonstrates connecting to the newly added Linear server, which requires authentication via Linear's OAuth flow.

8. Observability and Auditing:

• Audit Logs: Provides a detailed log of all activities within the system, including tool calls and server interactions.
  • Filtering: Logs can be filtered by various table columns.
  • Inspiration: Draws inspiration from modern cloud console logging dashboards and tools like Datadog.
• Usage Insights: Tracks usage of MCP servers and tool calls, identifying most used components and response times.
  • Example: Observing that "fire crawls" consistently has long response times due to web scraping.
• Chat Threads: Allows administrators to view and debug chat conversations.

9. Filters and Guardrails:

• Web Hook Based: Filters are implemented as web hooks that are called when an MCP server call is made.
• Selectors: Define specific tool methods or identifiers to trigger the filter.
• Example Filter: A filter that detects the word "hacking" and rejects the call.
• Flexibility: Designed for maximum flexibility, allowing users to bring their own filters.

10. Target Market and Pitch:

• Enterprise Focus: Designed for organizations with forward-looking architecture teams who anticipate MCP adoption.
• Value Proposition: Provides control, management, and visibility into MCP systems from day one.
• Problem Solved: Addresses the chaos of managing MCP server access, which is often done through informal methods like SharePoint documents.
