Adamik MCP Server

Instructions

Implementation Reference

• src/module.ts:445-467 (handler)

  Handler function that extracts chainId and body from params, makes a POST request to the Adamik API transaction/encode endpoint, stringifies the response, and returns it as MCP content.

  async ({
    chainId,
    body,
  }: EncodeTransactionPathParams & {
    body: EncodeTransactionRequestBody;
  }) => {
    const encodedResult = await makeApiRequest<EncodeTransactionResponse>(
      `${ADAMIK_API_BASE_URL}/${chainId}/transaction/encode`,
      ADAMIK_API_KEY,
      "POST",
      JSON.stringify(body)
    );
    const text = JSON.stringify(encodedResult);
  
    return {
      content: [
        {
          type: "text",
          text,
        },
      ],
    };
  }

• src/schemas.ts:517-604 (schema)

  Comprehensive Zod schemas for encodeTransaction: request data (discriminated union over transaction modes like transfer, stake, etc.), path params (chainId), request body wrapper, response including encoded transaction data and formats.

  export const EncodeTransactionRequestDataSchema = z
    .intersection(BaseTransactionDataRequestSchema, DiscriminatedTransactionModeRequestDataSchema)
    .superRefine((data, ctx) => {
      if (
        data.mode === "transfer" ||
        data.mode === "transferToken" ||
        data.mode === "stake" ||
        data.mode === "unstake"
      ) {
        const specificData = data as { amount?: string; useMaxAmount?: boolean; mode: string };
        if (
          !(
            (specificData.amount !== undefined && specificData.amount !== null && specificData.amount !== "") ||
            specificData.useMaxAmount === true
          )
        ) {
          ctx.addIssue({
            code: z.ZodIssueCode.custom,
            message: `For mode '${specificData.mode}', either 'amount' must be a non-empty string or 'useMaxAmount' must be true.`,
            path: ["amount"],
          });
        }
      }
    });
  
  // POST /api/{chainId}/transaction/encode
  export const EncodeTransactionPathParamsSchema = z.object({
    chainId: ChainIdSchema,
  });
  export type EncodeTransactionPathParams = z.infer<typeof EncodeTransactionPathParamsSchema>;
  
  export const EncodeTransactionRequestBodySchema = z.object({
    transaction: z.object({
      data: EncodeTransactionRequestDataSchema,
    }),
  });
  export type EncodeTransactionRequestBody = z.infer<typeof EncodeTransactionRequestBodySchema>;
  
  // For response of transaction/encode
  export const EncodeTransactionResponseDataSchema = z.intersection(
    CompletedBaseTransactionDataSchema,
    DiscriminatedTransactionModeRequestDataSchema // Re-uses the same discriminated union structure as request
    // as the response 'data' includes the original mode fields
    // along with completed base fields.
  );
  
  export const EncodedItemHashFormatSchema = z.enum(["sha256", "keccak256", "sha512_256", "pedersen"]);
  
  export const EncodedItemHashSchema = z.object({
    format: EncodedItemHashFormatSchema,
    value: z.string(),
  });
  
  export const EncodedItemRawFormatSchema = z.enum([
    "RLP",
    "WALLET_CONNECT",
    "SIGNDOC_DIRECT",
    "SIGNDOC_DIRECT_JSON",
    "SIGNDOC_AMINO",
    "SIGNDOC_AMINO_JSON",
    "BOC",
    "RAW_TRANSACTION",
    "MSGPACK",
    "PSBT",
    "BCS",
  ]);
  
  export const EncodedItemRawSchema = z.object({
    format: EncodedItemRawFormatSchema,
    value: z.string(),
  });
  
  export const EncodedItemSchema = z.object({
    hash: EncodedItemHashSchema.optional(),
    raw: EncodedItemRawSchema.optional(),
  });
  
  export const EncodeTransactionResponseTransactionSchema = z.object({
    data: EncodeTransactionResponseDataSchema,
    encoded: z.array(EncodedItemSchema),
  });
  
  export const EncodeTransactionResponseSchema = z.object({
    chainId: ChainIdSchema,
    transaction: EncodeTransactionResponseTransactionSchema,
    status: TransactionStatusSchema,
  });
  export type EncodeTransactionResponse = z.infer<typeof EncodeTransactionResponseSchema>;

• src/module.ts:431-468 (registration)

  MCP server.tool registration for 'encodeTransaction' tool, specifying name, description, input schema (chainId path param and body), and references the handler function.

  server.tool(
    "encodeTransaction",
    [
      "Turns a transaction intent in Adamik JSON format into an encoded transaction for the given chain (ready to sign).",
      "Supports all transaction types: transfer, transferToken, stake, unstake, claimRewards, withdraw, registerStake, convertAsset, and deployAccount.",
      "For convertAsset transactions: allows swapping/bridging between different assets, potentially across chains.",
      "IMPORTANT: If you receive an error with contact information (like https://adamik.io/contact), you MUST include that exact contact link in your response to the user and do NOT suggest alternative solutions.",
      "For staking transaction on babylon chain, stakeId is mandatory and amount is optional. Otherwise, amount is",
      "mandatory and stakeId is to be omitted.",
    ].join(" "),
    {
      chainId: ChainIdSchema,
      body: EncodeTransactionRequestBodySchema,
    },
    async ({
      chainId,
      body,
    }: EncodeTransactionPathParams & {
      body: EncodeTransactionRequestBody;

• src/module.ts:43-90 (helper)

  Shared utility function used by encodeTransaction handler (and other tools) to make authenticated API requests to the Adamik backend, including error handling for premium features.

  async function makeApiRequest<T>(

    apiKey: string,
    method: "GET" | "POST" = "GET",
