Adamik MCP Server

Instructions

Implementation Reference

• src/module.ts:241-258 (handler)

  The core handler function that implements the listFeatures tool logic: validates the provided chainId against supported chains, fetches chain details (features, native currency decimals, etc.) from the Adamik API, and returns the JSON-stringified response as text content.

  async ({ chainId }) => {
    if (!chains.includes(chainId)) {
      throw new Error(`Chain ${chainId} is not supported`);
    }
    const features = await makeApiRequest<GetChainDetailsResponse>(
      `${ADAMIK_API_BASE_URL}/chains/${chainId}`,
      ADAMIK_API_KEY
    );
    const text = JSON.stringify(features);
    return {
      content: [
        {
          type: "text",
          text,
        },
      ],
    };
  }

• src/module.ts:235-259 (registration)

  MCP server registration of the listFeatures tool, specifying the tool name, description, input schema (chainId: ChainIdSchema), and handler function.

  server.tool(
    "listFeatures",
    "Get chain details including supported features (read, write, token, validators) and native currency information (ticker, decimals, chain name)",
    {
      chainId: ChainIdSchema,
    },
    async ({ chainId }) => {
      if (!chains.includes(chainId)) {
        throw new Error(`Chain ${chainId} is not supported`);
      }
      const features = await makeApiRequest<GetChainDetailsResponse>(
        `${ADAMIK_API_BASE_URL}/chains/${chainId}`,
        ADAMIK_API_KEY
      );
      const text = JSON.stringify(features);
      return {
        content: [
          {
            type: "text",
            text,
          },
        ],
      };
    }
  );

• src/schemas.ts:6-6 (schema)

  Zod schema for chainId input parameter: z.string().

  export const ChainIdSchema = z.string();

• src/schemas.ts:102-112 (schema)

  Zod schema defining the ChainDetail structure returned by the API, including native currency details (ticker, decimals) and supported features - used to type the listFeatures response via GetChainDetailsResponse.

  export const ChainDetailSchema = z.object({
    family: ChainFamilySchema,
    id: ChainIdSchema,
    nativeId: z.string(),
    name: z.string(),
    ticker: z.string(),
    decimals: z.number(),
    isTestnetFor: z.string().optional(),
    supportedFeatures: ChainSupportedFeaturesSchema,
    signerSpec: SignerSpecSchema,
  });

• src/module.ts:42-90 (helper)

  Helper function makeApiRequest used by the handler to perform authenticated HTTP requests to the Adamik API endpoint `/chains/{chainId}`.

  // Helper function for making Adamik API requests
  async function makeApiRequest<T>(
    url: string,
    apiKey: string,
    method: "GET" | "POST" = "GET",
    body?: any
  ): Promise<T | ApiError> {
    const headers = {
      Accept: "application/json",
      Authorization: apiKey,
      "Content-Type": "application/json",
      "User-Agent": "Adamik MCP Server",
    };
  
    const response = await fetch(url, {
      headers,
      body,
      method,
    });
    const data = await response.json();
  
    // Check for specific Premium feature limitation error
    if (response.status === 501) {
      let errorMessage = "";
  
      // Try different possible error response structures
      if (data.status?.errors?.length > 0) {
        errorMessage = data.status.errors[0]?.message || "";
      } else if (data.errors?.length > 0) {
        errorMessage = data.errors[0]?.message || "";
      } else if (data.message) {
        errorMessage = data.message;
      }
  
      // Check for convertAsset Premium limitation with flexible matching
      const lowerErrorMessage = errorMessage.toLowerCase();
      if (lowerErrorMessage.includes("convert asset") && lowerErrorMessage.includes("premium")) {
        throw new Error(
          `ADAMIK_PREMIUM_REQUIRED: The convertAsset feature requires an Adamik Premium subscription. ` +
            `This feature allows you to swap and bridge assets across different chains. ` +
