MCP Servers

The Model Context Protocol (MCP) is an open standard for connecting AI agents to external tools and data. Add an MCP server and Agentastic discovers its tools and lets the agent call them — connecting to any API, database, or service you like.

Add a server

In Settings → Tools and Plugins → MCP Servers, click Add server and fill in:

  • Server name — a display name.
  • Server URL — the server endpoint, e.g. https://api.example.com/mcp.
  • API key (optional) — an authentication token.
  • Custom headers (optional) — additional key/value headers for auth.

Click Test connection to verify connectivity and list the tools the server exposes, then Add server to save.

What MCP adds

Once connected, an MCP server can provide:

  • Tools — callable actions the agent can use, with typed inputs and outputs.
  • Resources — files, documents, or data the agent can read.
  • Prompts — ready-made prompts the server offers to guide the agent.

Agentastic auto-discovers everything the server exposes on connection.

Manage servers

Each configured server has controls to:

  • Enable / Disable it,
  • Sync tools to refresh the tool list from the server,
  • Edit its name, URL, or credentials,
  • Delete it,
  • and show/hide the stored API key.

The test result shows how many tools were found and their names, so you can confirm a server is wired up correctly.

Tips

  • Start with Test connection before saving — it's the fastest way to catch a bad URL or token.
  • If a server adds or renames tools, hit Sync tools so Agentastic sees the changes.
  • Combine MCP tools with Skills to teach the agent when and how to use them.
