Ollama MCP Server

Instructions

Implementation Reference

• src/tools/pull.ts:7-23 (handler)

  Core handler function that performs the ollama.pull operation to download the specified model.

  /**
   * Pull a model from the Ollama registry
   */
  export async function pullModel(
    ollama: Ollama,
    model: string,
    insecure: boolean,
    format: ResponseFormat
  ): Promise<string> {
    const response = await ollama.pull({
      model,
      insecure,
      stream: false,
    });
  
    return formatResponse(JSON.stringify(response), format);
  }

• src/schemas.ts:146-153 (schema)

  Zod schema used for input validation in the ollama_pull tool handler.

  /**
   * Schema for ollama_pull tool
   */
  export const PullModelInputSchema = z.object({
    model: z.string().min(1),
    insecure: z.boolean().default(false),
    format: ResponseFormatSchema.default('json'),
  });

• src/tools/pull.ts:25-53 (registration)

  Tool definition export that registers the 'ollama_pull' tool, including its description, inline input schema, and handler wrapper that performs validation and delegates to the core pullModel function. Auto-loaded by src/autoloader.ts.

  export const toolDefinition: ToolDefinition = {
    name: 'ollama_pull',
    description:
      'Pull a model from the Ollama registry. Downloads the model to make it available locally.',
    inputSchema: {
      type: 'object',
      properties: {
        model: {
          type: 'string',
          description: 'Name of the model to pull',
        },
        insecure: {
          type: 'boolean',
          description: 'Allow insecure connections',
          default: false,
        },
        format: {
          type: 'string',
          enum: ['json', 'markdown'],
          default: 'json',
        },
      },
      required: ['model'],
    },
    handler: async (ollama: Ollama, args: Record<string, unknown>, format: ResponseFormat) => {
      const validated = PullModelInputSchema.parse(args);
      return pullModel(ollama, validated.model, validated.insecure, format);
    },
  };
