Implementation Reference

• src/index.ts:101-118 (handler)

  The handler for the 'save_json_doc' tool. It extracts the 'doc' from arguments, validates it, saves it to the Fireproof database with a 'created' timestamp, and returns a message with the saved document's ID.

  case "save_json_doc": {
    const doc = request.params.arguments?.doc;
    if (!doc) {
      throw new Error("Document is required");
    }
  
    const response = await db.put({
      ...doc,
      created: Date.now()
    });
  
    return {
      content: [{
        type: "text",
        text: `Saved document with ID: ${response.id}`
      }]
    };
  }

• src/index.ts:39-52 (registration)

  The tool registration in the ListTools response, defining name, description, and input schema for 'save_json_doc'.

  {
    name: "save_json_doc",
    description: "Save a JSON document",
    inputSchema: {
      type: "object",
      properties: {
        doc: {
          type: "object",
          description: "JSON document to save"
        }
      },
      required: ["doc"]
    }
  },

• src/index.ts:42-51 (schema)

  Input schema for the 'save_json_doc' tool, requiring a 'doc' object.

  inputSchema: {
    type: "object",
    properties: {
      doc: {
        type: "object",
        description: "JSON document to save"
      }
    },
    required: ["doc"]
