Not a standard server
A better open-source AI chatbot with multi-model, MCP tools, and visual workflows.

This is not a typical connect-and-use MCP server; read the source repository before using it.

This MCP server is actually a full AI chat application that acts as an MCP client (can connect to other MCP servers) and also provides its own MCP-related tools. It is ideal for users who need to integrate multiple AI capabilities and tools into one interface. Due to its feature richness, deployment and configuration are relatively complex, but it offers detailed documentation and quick deployment options.

Why each score
Reliability 3/20
No server manifest, source, tests, or CI evidence was supplied. The README claims MCP support and shows demos, but there is no tool list, handshake verification, or error-handling detail, so the happy path cannot be confirmed.
Security and permissions 5/20
The README shows env-based keys, BETTER_AUTH_SECRET, options to disable sign-ups/add-MCP, and a manual tool-permission mode; however no source verifies credential handling, least privilege, default confirmation for dangerous actions (e.g., JS/Python execution), or data boundaries.
Maintenance 7/20
The repo is not archived and has an MIT license, with a contributing guide and Discord in the README; but there is no evidence of releases, commit cadence, dependency updates, or a security-response channel. The 50 open issues are not characterized, so full credit cannot be given.
Documentation 9/20
The README provides layered quick-start, env-var, Docker/Vercel/OAuth/MCP guides, previews, and a roadmap; however the actual MCP server manifest/tool-parameter docs are absent, troubleshooting and limitations are missing, and the MCP guide is only a link without included content.
Setup experience 8/20
The README gives Docker Compose and local install paths and lists required env vars; but it needs pnpm, Postgres, multiple API keys, and storage configuration, making it manual and fragile, and there is no mainstream-client connection example for this server.

Fit and risk

What it can accessRuns commands or codeUses the networkControls a browser

Best for

  • Developers
  • Technical teams
  • Users needing flexible AI tool integration
  • Users who want a self-hosted AI chat solution

Not for

  • Non-technical users, as deployment and configuration require a certain level of expertise
  • Enterprises needing official support
  • Users who prefer a lightweight chat interface may find it too complex

Required permissions

  • Read environment variables for API keys
  • Access to configured database (PostgreSQL)
  • Access external APIs (LLM, Exa, etc.) as configured
  • If enabled, access to file storage (Vercel Blob)
  • Execute tools provided by MCP servers (e.g., browser control)

Risks and side effects

  • User-configured MCP servers may execute dangerous operations; authorize with caution
  • API keys stored in environment variables; ensure server security
  • Code execution tools may run malicious code; restrict usage
  • Data storage and privacy depend on self-hosting or cloud deployment

DISABLE_SIGN_UP optional Set to 1 to disable user sign-ups.
NOT_ALLOW_ADD_MCP_SERVERS optional Set to 1 to disallow adding MCP servers.
  1. Clone the repository.
  2. Run pnpm i to install dependencies (generates .env file).
  3. Fill in at least one LLM provider API key (e.g., OPENAI_API_KEY) in the .env file.
  4. Optionally, start a PostgreSQL database (pnpm docker:pg or use Docker Compose).
  5. Run pnpm build:local && pnpm start to start the app.
  6. Open http://localhost:3000 to begin.

Check that it works

After starting with pnpm docker-compose:up, open http://localhost:3000, type @ in a chat and confirm tools like web-search, js-executor, and image-generation appear in the tool list.

Troubleshooting

  1. Ensure all required API keys are correctly set.
  2. Verify that PostgreSQL is running and the connection URL is correct.
  3. Check the .env file for proper configuration.
  4. Review server logs for error messages.
  5. If using Docker, check that containers are running correctly.

Things to try

Once connected, you can ask your AI assistant things like:

  • Use @web-search to look up information about modelcontextprotocol
  • Generate an image of a sunset beach with image-generation
  • Run a script with js-executor to compute the first 10 Fibonacci numbers
  • Use the playwright MCP to navigate to Google and click the Login button
