Implementation Reference

• src/index.ts:21-68 (handler)

  The handler function for the 'get_artist' tool. It fetches artist data from the Spotify API using the provided HTTP method, processes the response, extracts artist names, and returns them in a text content block.

  async ({ method }) => {
    const methodUpper = method.toUpperCase();
    const artistData = await fetch("https://api.spotify.com/v1/artists?ids=0TnOYISbd1XYRBk9myaseg", {
      headers: {
        Authorization: `Bearer ${accessToken}`,
      },
      method
  })
  
  if (!artistData) {
  return {
      content: [
      {
          type: "text",
          text: "Failed to retrieve tracks",
      },
      ],
  };
  }
  const allArtistsData = await artistData.json()
  console.log(allArtistsData)
  const data = allArtistsData.artists || [];
  if (data.length===0) {
  return {
      content: [
      {
          type: "text",
          text: `No artists`,
      },
      ],
  };
  }
  let names = []
  for(let i = 0; i<data.length; i++){
      names.push(data[i].name)
  }
  
  const finalOutput = `Artist name is ${names}`;
  
  return {
      content: [
          {
              type: "text",
              text: finalOutput,
          },
      ],
      };
  },

• src/index.ts:18-20 (schema)

  Input schema defined using Zod, specifying a 'method' parameter as a string with minimum length 3.

  {
    method: z.string().min(3).describe("Get or post request")
  },

• src/index.ts:15-69 (registration)

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

  server.tool(
      "get_artist",
      "Get Artist name",
      {
        method: z.string().min(3).describe("Get or post request")
      },
      async ({ method }) => {
        const methodUpper = method.toUpperCase();
        const artistData = await fetch("https://api.spotify.com/v1/artists?ids=0TnOYISbd1XYRBk9myaseg", {
          headers: {
            Authorization: `Bearer ${accessToken}`,
          },
          method
      })
      
      if (!artistData) {
      return {
          content: [
          {
              type: "text",
              text: "Failed to retrieve tracks",
          },
          ],
      };
      }
      const allArtistsData = await artistData.json()
      console.log(allArtistsData)
      const data = allArtistsData.artists || [];
      if (data.length===0) {
      return {
          content: [
          {
              type: "text",
              text: `No artists`,
          },
          ],
      };
      }
      let names = []
      for(let i = 0; i<data.length; i++){
          names.push(data[i].name)
      }
  
      const finalOutput = `Artist name is ${names}`;
  
      return {
          content: [
              {
                  type: "text",
                  text: finalOutput,
              },
          ],
          };
      },
