Ollama MCP Server

Instructions

Implementation Reference

• src/index.ts:54-61 (handler)

  The handler function for the 'show' tool. It takes a model name, calls ollama.show to retrieve model information, formats it as JSON, and returns it. Includes error handling using the formatError helper.

  async ({ name }) => {
    try {
      const result = await ollama.show({ model: name });
      return { content: [{ type: "text", text: JSON.stringify(result, null, 2) }] };
    } catch (error) {
      return { content: [{ type: "text", text: `Error: ${formatError(error)}` }], isError: true };
    }
  }

• src/index.ts:52-52 (schema)

  Input schema for the 'show' tool, validating the 'name' parameter as a string using Zod.

  inputSchema: { name: z.string() },

• src/index.ts:47-62 (registration)

  Registration of the 'show' tool on the MCP server, including the tool name, metadata, input schema, and inline handler function.

  server.registerTool(
    "show",
    {
      title: "Show model info",
      description: "Show information for a model",
      inputSchema: { name: z.string() },
    },
    async ({ name }) => {
      try {
        const result = await ollama.show({ model: name });
        return { content: [{ type: "text", text: JSON.stringify(result, null, 2) }] };
      } catch (error) {
        return { content: [{ type: "text", text: `Error: ${formatError(error)}` }], isError: true };
      }
    }
  );
