Akave MCP Server

Instructions

Implementation Reference

• src/server.ts:188-193 (handler)

  The handler function for the 'update_object' MCP tool. It calls the S3Client's updateObject method with the provided bucket, key, and body, then returns a success response.

  async ({ bucket, key, body }) => {
    await this.s3Client.updateObject(bucket, key, body);
    return {
      content: [{ type: "text", text: JSON.stringify({ success: true }) }],
    };
  }

• src/server.ts:183-187 (schema)

  Input schema validation for the 'update_object' tool using Zod, defining bucket, key, and body parameters.

  {
    bucket: z.string().describe("Bucket name"),
    key: z.string().describe("Object key"),
    body: z.string().describe("New object content"),
  },

• src/server.ts:180-194 (registration)

  Registration of the 'update_object' tool on the MCP server, including name, description, input schema, and handler.

  this.server.tool(
    "update_object",
    "Update (overwrite) an object in a bucket",
    {
      bucket: z.string().describe("Bucket name"),
      key: z.string().describe("Object key"),
      body: z.string().describe("New object content"),
    },
    async ({ bucket, key, body }) => {
      await this.s3Client.updateObject(bucket, key, body);
      return {
        content: [{ type: "text", text: JSON.stringify({ success: true }) }],
      };
    }
  );

• src/s3Client.ts:127-130 (helper)

  Supporting helper method in S3Client class that implements object update by delegating to putObject (which overwrites existing objects).

  async updateObject(bucket: string, key: string, body: string) {
    // S3 putObject overwrites by default
    return this.putObject(bucket, key, body);
  }
